37 Backrest exercises with template

Here you can test if you know how to correctly use the backquote. Do not waste time! Do the exercises and check the answers.

question 1

(Banco do Brasil) Option that correctly fills in the blanks: The manager went to ___ his office and started to ___ speak to ___ all the people called.

a) to - to - to
b) to - to - to
c) a - a - a
d) to - to - to
e) to - to - to

See Answer

Alternative c: à - a - a.

• The manager went to his office. - Before possessive pronouns, the use of the crasis is optional. So “yours” or “yours” are correct.
• He started talking. - Before verbs in the infinitive, do not use a crasis, because in this case there is only preposition. The crase is only used when, in addition to the preposition, there is a definite article "a".
• To all the people. - In this case, the crase is not used because there is no contraction of the definite article “a” with the preposition “a”.

question 2

(Banespa) Check the alternative that correctly fills in the blanks in the text opposite: "It used ___ sister and ___ she clung like ___ a lifeline."

a) to - to - to
b) to - to - to
c) a - a - a
d) to - to - to
e) to - to - to

See Answer

Alternative e: à - a - a.

• He turned to his sister. - The crase is used before feminine words, when it marks the contraction of preposition “a” with definite article “a”.
• To her he clung. - Do not use a crasis before personal pronouns of the straight case (in this case, “she”).
• To a lifeline. - Do not use a back quote before indefinite articles (in this case, “an”). The backquote marks the contraction of the preposition “a” with a definite article “a”, and not with an indefinite article “an”.

question 3

(Cescem) He sat down ___ the machine and started to ___ rewrite one ___ one of the pages of the report.

a) to - to - to
b) to - to - to
c) à - à - à
d) a - a - a

See Answer

Alternative d: à - a - a.

• He sat down at the machine. - The back is used before feminine words. It marks the contraction of a (preposition) + a (article).
• He began to rewrite. - Before verbs in the infinitive, do not use a crasis, because in this case there is only preposition. The crase is only used when, in addition to the preposition, there is a definite article "a".
• One by one. - Do not use a back quote before indefinite articles (in this case, “an”). This is because the crase only signals the contraction of the preposition “a” with the definite article “a”.

question 4

(Cesgranrio) Tick the sentence in which à or at is badly employed.

a) Love in sight.
b) I referred to the unreasonableness of love.
c) I disobeyed sentimental limitations.
d) My heart was at the mercy of passions.
e) Submitted love to difficult trials.

See Answer

Alternative e: They subjected love to difficult trials.
In this case, there is no contraction of a + a, as there is only the preposition, without the occurrence of an article.

As for the other alternatives, “on sight” (a) and “at mercy” (d) both are adverbial phrases, cases in which the back is used.

With regard to alternative (b), the crasis is used to mark the sum of the preposition “a” with the article “a ” (Refer to, that “a” is a preposition; the unreasonable, this “as” is an article). The same happens in alternative ©, (disobey the + the limitations).

question 5

(FEI) Mark the alternative that correctly fills in the gaps in the following sentences:

I. Need to speak ___ about three thousand workers.
II. In ___ a few years everything will be changed.
III. ___ days is gone.
IV. Coming from far away, everyone arrived at ___ time ___ meeting.

a) a - a - there is - a - a
b) à - a - a - there is - a
c) a - a - a - a - there is
d) there is - a - a - a - a
e) a - there is - a - a - a.

See Answer

Alternative a: a - a - there is - a - a.

I. Need to talk about… - “About” is a word, which is classified as an adverb.

II. In a few years. - The sentence contains a preposition, but it does not contain an article. For this reason, the “a” is not crased.

III. It's been missing for days. - “Ha” refers to the past.

IV. They arrived on time. - The sentence contains a preposition, but it does not contain an article. For this reason, the “a” is not crased. Remembering that “time” is a male word.

V. They arrived at the meeting. - Arrived at (preposition) + (article) meeting. In this sentence, we have everything that is necessary to constitute a crasis (a + a = à).

question 6

(FGV) Tick the alternative in which the use of the accent indicative of back is correct:

a) The author compared himself to someone who has a good memory.
b) He referred to people with good memory.
c) People allude to a specific cause.
d) He came to be understood based on his reflections on memory.
e) The books were delivered to him.

See Answer

Alternative b: He referred to people with good memory.
There is a crasis because the sentence has a preposition and an article (referring to + people).

In “The author compared himself to someone.”(a) there is no backquote because before the indefinite pronoun “someone” an article is not used, but only the preposition. Therefore, the correct thing is “The author compared himself to someone”.

The same happens in "The books were given to him." (d), because before the personal pronouns of the straight case (in this case, “he”), there is no crasis. The correct one is "The books were given to him."

As for alternative (c), “People allude to a cause.”, There is no crasis because there is no contraction of the preposition a with an indefinite article “a”. The contraction occurs with a (preposition) + a (definite article). Therefore, the correct thing is “People allude to a cause”.

question 7

(Registrar. Pol./SP) The alternative in which the backquote sign does not proceed is:

a) With the exception of Bandeirantes, the other television stations hold the broad leadership with fabulous percentages.
b) The filmmaker from Brazilian cities is present, and the percentage of 7% was a surprise.
c) The survey data refer to scenes, certainly unparalleled, anywhere else in the world.
d) Secretly, the number of cities receiving television images, threatening cultural-ethical values, is growing.

See Answer

Alternative b: The filmmaker from Brazilian cities is present, and the percentage of 7% was a surprise.
In “to whom” it is not possible to make the contraction of a + a because the sentence contains only a preposition, that is, only an “a”.

“Except” (a) “in secret”(d) are phrases, and before phrases there is a backstack.

In “at scenes” (c), “scene” is a feminine word that is accompanied by the feminine definite article in the plural "as" and is also accompanied by the preposition "a", and therefore must be marked by the grave accent (`).

question 8

(FASP) Tick the alternative with a backstroke:

a) none of the alternatives are wrong.
b) Have you ever been to Rome? I will go to Rome soon.
c) I went to my grandparents' Lisbon, because I like my grandparents' Lisbon.
d) I don't like going to Brasília anymore. Gasoline…
e) I refer to ancient Rome, in which Caesar lived.

See Answer

Alternative b: Have you ever been to Rome? I will go to Rome soon.

The correct one is “I'll go to Rome soon.”, as well as “I don't like going to Brasília anymore” (without an underline).

At the same time, “I went to my grandparents' Lisbon.” and "I mean ancient Rome." (with backstroke).

For these occurrences, the tip is as follows:

I'm going to, back from, back there! I go to, come back from, back to what?

Thus, in “I'm going to Rome, I'm coming back from Rome.”, “I'm going to Brasília, I'm coming back from Brasília.”, there is no crasis, as in “I'm going to Lisbon, I'm coming back from Lisbon.”.

But why "I went to Lisbon for my grandparents." and "I mean ancient Rome." are they crased? Because in those cases, the articles were not repulsed. By specifying Lisbon and Rome, respectively, as “the Lisbon of my grandparents”, “ancient Rome”, we would say “return from the Lisbon of my grandparents”, “I return from ancient Rome”.

question 9

(FESP) I mean ___ adult attitudes that actually lead girls to ___ senseless rebellion and ___ senseless escape.

a) at - to - to
b) as - to - to
c) at - at - at
d) a - a - a
e) to - to - to

See Answer

Alternative c: at - to - a.

“I mean attitudes” (a + as) - Contraction of the preposition “a” (I mean a) with the article “as” (attitudes). The same happens with “They lead the girls to rebellion” (a + a).

In “They Lead the Girls to an Escape”, in turn, there is no contraction of a + a. As there is only preposition, there is no crasis.

question 10

(IBGE) Check the incorrect option regarding the use of the accent indicative of crasis:

a) The researcher paid more attention to the less privileged city.
b) This statistical result could belong to any poor population.
c) Even late, the enumerator attended the interview.
d) The approved budget is intended only for that country town.
e) Veranópolis knew how to combine activity with prosperity.

See Answer

Alternative b: This statistical result could belong to any poor population.
Because it is the only case in which the a + a contraction does not occur. Before indefinite pronouns (in this case, any) there is no backrest.

In the remaining alternatives, the contraction of a (preposition) + a (article) occurs:

• “was paying attention to + the city”;
• “attended the + the interview”;
• “Joining activity to + prosperity”;
• “Intended for + that city” (it is also possible to contract the preposition with demonstrative pronouns beginning with “a”: that, that, that).

question 11

(IFSP) Check the alternative that fills, correctly and respectively, the following sentence.

Those interested in adopting children have to resort to ___ Juvenile Court guidelines and be subjected to ___ an often long wait, which, despite everything, does not discourage ___ the majority.

a) at - at - at
b) at - at - at
c) at - to - to
d) as - to - to
e) as - to - to

See Answer

Alternative to: at - to - a.

• Use the guidelines - Contraction of the preposition "a" (use a) with the article "as" (the guidelines).
• And if you subject yourself to a wait - a + one does not contract, therefore it does not receive a backrest.
• It doesn't discourage the majority - there is no preposition, but only an article (the majority), which is why there is no crasis.

question 12

(ITA) Analyzing the sentences:

I. In view of this, we must take serious action.
II. Do not say such a thing to others.
III. Day by day the company grew.
IV. I don't care what you told me.

We can deduce that:

a) Only sentence III has no backslash.
b) Sentences III and IV do not have a backquote.
c) All sentences have a backquote.
d) No sentence has a backtape.
e) Only sentence IV has no backslash.

See Answer

Alternative to: Only sentence III has no backquote.

Despite being an adverbial phrase - cases in which a crasis occurs, such as "in view of this", alternative (a) -, repeated words are not crasised. Examples: face to face, drop by drop.

There is a crasis when there is contraction of a + a em. This is what happens in “Don't talk to others” (speak to + the others) and “I don't care about that (connect to + that).

question 13

(ITA) Given the statements:

1- Everything went wonderfully.
2 – We walk close to the wall.
3 – He never went to parties.

We verified that the use of the accent indicator of the crasis in the The is required:

a) only in sentence No. 1.
b) only in sentence No. 2.
c) only in sentences 1 and 2.
d) in all sentences.

See Answer

Alternative c: only in sentences 1 and 2.

There is a crasis in adverbial phrases, such as “a thousand marvels” and “near the wall”.

In "He never went to parties." because only the preposition “a” occurs (It was never a), that is, there is no contraction of a (preposition) + a (article).

question 14

(Official of Justice/SP) Check the alternative where the sign indicative of the crasis was used inappropriately:

a) I prefer this bag to that.
b) This is harmful to health.
c) Wrote to Machado de Assis.
d) He referred to Fabiana, not me.
e) Tears fell one by one from her eyes.

See Answer

Alternative e: Tears fell one by one from her eyes.
Although “one by one” is an adverbial phrase, there is no backquote because the repeated words are not backquoted. Example: day to day, face to face.

“À moda de” is a locution and is implied in alternative (c) “I wrote à Machado de Assis.”, which is why crasis occurs.

In all other alternatives, crasis occurs, because the contraction of a + a occurs:

• I prefer this one to + that bag;
• It is harmful to + health;
• You referred to + to Fabiana.

question 15

(Acafe) Check the correct alternative that fills in the blanks in the following sentence.

“The councilor who resides on ___ Rua Miguel Deodoro runs the risk of having his ___ ___as soon as the process arrives ___ in the hands of the President.

a) to - hunting warrant - the
b) at - hunted mandate - at
c) na - annulled writ - the
d) na - term revoked - at

See Answer

Alternative d: na - term revoked - at.

• Resides na - the regency of the verb “to reside” is “in”, that is, Rua Miguel Deodoro.
• Mandate (with “t”) is the authorization that one person gives to another to perform an act.
• Canceled (with “ss”) means annulment.
• Reaching the President's hands - Crasis occurs thanks to the occurrences of the preposition “a” and the article “as” (reaching + hands).

question 16

(Cesgranrio) Indicate the option in which the sign indicative of backstroke is correctly used.

a) This proposal suits everyone.
b) The government increased the amount of subsidies.
c) The company considered the offer inferior to the other.
d) He is likely to leave office.
e) I will not adhere to passing fads.

See Answer

Alternative c: The company considered the offer inferior to the other.
This is the only alternative in which the preposition a + article a (less than + the other) is contracted.

In “it suits everyone”, “prone to leave” and “adhere to fads” there is only preposition.

In “increased the quantity” only item occurs.

question 17

(TRE) The use of grave accent (indicating back or not) is incorrect in:

a) First I go to the fair, then I go to work.
b) Sometimes we cannot do what we are told.
c) We should not make references to those cases.
d) We will leave at five in the morning.
e) This would not be helpful to her.

See Answer

Alternative e: This would not be helpful to her.
Crasis does not occur before personal pronouns of the straight case (in this case, she), because there is no contraction of preposition a + article a.

In “I'm going to the fair” and “referring to those cases” there is a preposition and an article, so there is a crasis (I'm going to + the fair, referring to + those).

In verbal locutions there is a crasis (“sometimes”). As with the indication of exact hours, there is also a crasis (at five in the morning).

question 18

(TRE) The grave accent, indicator of crasis, is incorrectly used in:

a) This law necessarily applies to women of a violent nature.
b) The telenovelas, which I watched, problematize the drug issue.
c) He gave the keys to the store to the man who defied us in the square.
d) The delegate told the mayor and councilors that he was looking for the fugitives.
e) Good service to poor people must be a priority for the new administration.

See Answer

Alternative to: Such law necessarily applies to women of violent disposition.
The sentence contains only preposition, so there is no sum of the preposition a + article a (Applies to women).

In the remaining alternatives, a + a contraction occurs:

• I watched + the soap operas;
• He handed the keys to + that gentleman;
• I was looking for +;
• Service to + people.

question 19

(UFABC) The alternative in which the accent indicative of a crasis does not apply is:

a) Such information is the same as what I received yesterday.
b) I lost a pen similar to yours.
c) The construction of the house follows City Hall specifications.
d) The medicine should be taken drop by drop, not all at once.
e) He did not witness this operation, but that of his brother.

See Answer

Alternative d: The medicine should be taken drop by drop, not all at once.
“Gout a drop” is an adverbial phrase and the phrases must be accompanied by a crasis. However, phrases formed by repeated words should not be crased.

The remaining sentences must have a backtape because there is a contraction of the preposition a with article a, as in the following alternatives:

• a) Are equal to + the information;
• c) Complies with + the specifications;
• e) Watched + the (operation) of his brother.

Before possessive pronouns, the use of the crasis is optional. Thus, “I lost a pen similar to yours” or “I lost a pen similar to yours” are correct.

question 20

(UFABC) In the alternatives that follow, there are three sentences that may or may not be correct. Read them carefully and mark the right answer:

I. His selfishness was only matched by his ugliness.
II. He couldn't give in to his illusions.
III. Anyone who finds himself in trouble must go to court.

a) Only sentence II is correct.
b) Only sentences I and II are correct.
c) All three sentences are correct.
d) Only sentence I is correct.
e) Only sentences II and III are correct.

See Answer

Alternative c: All three sentences are correct.

Because in all sentences, the conditions for the crasis to occur are verified, that is, there is the preposition a and also the article a, which together are marked by the grave sign (`):

• Comparable to + its ugliness;
• Surrender to + your illusions;
• Resort to + justice.

question 21

(UFMS) Evaluate the following two sentences:

I. She smelled of pomegranate blossom.
II. She smelled of pomegranate blossom.

Considering the use of the backquote, it is correct to state:

a) Both sentences are written properly depending on context.
b) The two sentences are ambiguous in any context.
c) The first sentence means that someone gave off the scent of the pomegranate flower.
d) The second sentence means that someone has the scent of the pomegranate flower.
e) The “a” of the second sentence should contain the accent indicative of the crase.

See Answer

Alternatives a: Both sentences are spelled properly depending on context and c: The first sentence means that someone gave off the scent of the pomegranate flower.

In turn, the second sentence means that someone female sniffed a flower from the pomegranate tree.

question 22

(UFPR) In which alternative the word The should receive grave accent?

a) Painted the painting in oil.
b) We went to a village.
c) Addressed to Your Excellency.
d) He returned to his father's home.
e) It started to rain.

See Answer

Alternative d: Returned to parental home.
In this sentence, we have preposition a (back to) + article a (the paternal house), so there is a crasis.

In “Pintou a oil”, “We went to a village” and “It began to rain” there is only preposition (paint to/go to/began to).

In “They addressed Your Excellency.”, the crasis is optional before possessive pronouns (in this case, yours). Thus, it is also correct “They addressed Your Excellency.”.

question 23

(UFPR) What are the ways that complete, in order, the gaps in the following sentences?

From here ___ will start the exam; Attended ___ inauguration ceremony for new governor; Having not been able to go ___ to college today, I promise to attend ___ all classes tomorrow.

a) to - to - to - to
b) there is - na - to - a
c) a - there is - na - to
d) to - na - to - to
e) to - to - to - to

See Answer

Alternative e: a - à - à - a.

Sentences in which there is no contraction of preposition a + article a do not have a serious accent (backtape). This is the case of: “In a little while” and “I promise to attend all classes”, where there is only preposition.

In turn, there is a crasis in the phrases “I attended + the ceremony” and “Not having been able to go to + the college”.

question 24

(UFTM) Analyze the sentences.

I. Yesterday I went to school to visit old friends.
Yesterday I went to school to visit old friends.

II. Yesterday, I spent the night at my cousin's house.
Yesterday, I spent the night at my cousin's house.

III. Yesterday, I gave the report to my supervisor.
Yesterday, I gave the report to my supervisor.

Among the pairs of sentences presented, the sentence structure in which there is a change in the meaning of the second sentence in relation to the first is contained in:

a) I, only.
b) II, only.
c) I and III only.
d) II and III only.
e) I, II and III.

See Answer

Alternative b: II, only.

"Yesterday, I spent the night at my cousin's house." means I was at my cousin's house all night.

"Yesterday, I spent the night at my cousin's house." it means I went to my cousin's house at night.

In pairs I and III, both sentences are correct. This is because the use of the crase is optional after the preposition “until” and before possessive pronouns (in this case, mine).

question 25

(Unicenp-PR) What is the alternative that points out the incorrect sentence as to the accent indicative of the crase?

a) A woman gave birth over a sink while money from the SUS (Unified Health System) is diverted to buy beer and snacks.
b) This expedient led to the regrettable approval of the IPMF.
c) To the absolute inefficiency of the collection system, there is also the bad application of public resources.
d) In the 70s, Brazil's external image was often associated with allegations of torture.
e) The social issue remains too high a priority to be relegated to the background.

See Answer

Alternative e: The social issue remains too high a priority to be relegated to the background.
This is the only alternative that does not meet the conditions for the occurrence of the crasis. In it, there is only a preposition, without a feminine article (being relegated to + the background), so there is no crasis.

In the following alternatives, the contraction occurs (preposition a + article a):

• b) It led to a + to deplorable;
• c) The misapplication of resources is added to + the absolute inefficiency;
• d) Associated with + the complaints.

In turn, “giving birth” is an expression that takes crasis and has the same sense of giving birth.

question 26

(Unifor) Check the alternative in which the backstroke sign is used in all cases that it is necessary.

a) The family was at the mercy of the cold, despite the fire that was burning.
b) The wind blew in, leaving the family with the expectation that it would happen soon.
c) They talked a lot, but maybe they didn't understand each other very well.
d) The dog stayed at the door, looking at the embers.
e) The lack of better expression resorted to energetic speeches.

See Answer

Alternative to: The family was at the mercy of the cold despite the fire that was burning.

“At mercy” is an adverbial phrase, in which case we use a back letter. “Despite” and “to burn” are not phrases and neither do they meet the conditions for the crasis to occur, that is, the presence of the preposition “a” plus article “a”.

Both in “despite” and “on fire” there is only preposition.

Correction of remaining alternatives:

• b) The wind blew in, leaving the family with the expectation that it would happen soon. (remaining + the family)
• c) They talked a lot, but maybe they didn't understand each other very well. (“a lot” is an expression, but “to my satisfaction” is not. “Content” is a masculine word and, therefore, does not match the feminine article “a”, therefore, there is no crasis.
• d) The dog stayed at the door, looking at the embers. (contraction of a + a: it was a + the door)
• e) The lack of better expression resorted to energetic speeches. (there is no contraction of a + a, as there is only preposition: they resorted to + speeches)

question 27

(Vunesp)

a) Fury surrenders ___ vuvuzelas.
b) Cain is the last book by José Saramago, who died ___ one week.
c) Subject ___ mood swings, he does not live in peace.
d) The upstairs neighbors? I haven't ___see in a long time.

a) at - there - at - at
b) the - there - the - at
c) at - at - at - at
d) at - at - at - at

See Answer

Alternative to: at - there - at - at.

a) It surrenders to + the vuvuzelas = to

b) Died a week ago (ha = past of the verb “haver”)

c) Subject to + seizures = to

d) I don't see the (neighbors), there is no contraction of a + a, so there is no crasis.

question 28

(Vunesp) Tick the correct alternative regarding the use of the accent indicative of the back letter.

a) I know she is the wife of an actor named Tom Cruise, who I also only saw one movie: “With Eyes Wide Shut”.
b) Orthopedists warn when high heels are not suitable for a bone structure in formation.
c) Orthopedists observe that the bone structure in formation will only be completed after 12 or 13 years of age.
d) The problem is not limited to the children of Hollywood or those of famous parents.
e) We are generating adult children, who will hardly reach maturity.

See Answer

Alternative d: The problem is not limited to Hollywood kids or those of famous parents.

Contraction of preposition a + article a:
is not limited to + children = at
is not limited to + those (children) of famous parents = those

Correction of remaining alternatives:

a) I know she is the wife of an actor named Tom Cruise, who I also only saw one movie: “With Eyes Wide Shut”. (I watched + a movie, there is no contraction, so there is no crasis)

b) Orthopedists warn when high heels are not suitable for a bone structure in formation. (suitable for + a structure, there is no contraction, so there is no crasis)

c) Orthopedists observe that the bone structure in formation will only be completed after the age of 12 or 13 years. (despite “from” being a phrase, there is no crasis before verbs in the infinitive – in this case, to start, which means to have origin, beginning).

e) We are generating adult children, who will hardly reach maturity. (Before verbs, there is no backtape).

question 29

(Vunesp) Check the alternative that completes, correctly and respectively, the gaps in the sentences.

___ unsustainable garbage situations in the capital. This problem comes to ___ authorities who must take ___ appropriate action.

a) The - the - the
b) There are - at - the
c) There are - the - at
d) At - at - at
e) The - are - the

See Answer

Alternative b: There are - at - as.

• There has the meaning of existing;
• Arrives at + authorities - contraction of preposition a + article a = at;
• Take the necessary steps - there is no contraction, as there is only the “as” article, so there is no backlash.

question 30

(Vunesp) Check the phrase in which the back-accent indicator is used correctly.

a) We sell CDs starting at R$10.
b) All our products can be purchased in installments.
c) You will be referred to one of our managers.
d) The pieces of the showcase are also for sale.
e) You are invited to discover our home appliance sector.

See Answer

Alternative d: Showcase parts are also for sale.

Although some authors dispense with the use of the crasis in the expression “on sale/sale”, it is often used in disambiguation. For example: put the blindfold (blinded eyes) and put it up for sale (in order to sell something).

In the remaining alternatives, do not use a backquote because there is no contraction of the preposition a + article a):

Purchased at + the term;

Referred to + one of our managers.

Remembering that crasis does not occur before verbs in the infinitive, in this case, depart (a) and know (e).

question 31

Fill in the gaps with a or à.

___ It was cool in the afternoon, so he decided he would take a walk in the garden ___ in the afternoon after work. He went to ___ the office, asked ___ the secretary where the boss was and ___ the secretary informed that the executive had left ___ two to take___ three daughters to ___ school.

See Answer

The afternoon was cool, so he decided he would take a walk in the garden in the afternoon after work. She went to the secretary's office, asked the secretary where the boss was, and the secretary informed her that the executive had left at two to take his three daughters to school.

• In the afternoon there was, the secretary, the three daughters: there is only an article, so there is no contraction of the preposition a + article a, and there is no backrest;
• in the afternoon: it is a locution, cases in which there is a crasis;
• went to, asked to, take to: there is a contraction of a + a = à (he went to + the secretary, asked + the secretary, take a + to school);
• at two - the back is used in the indication of exact times.

question 32

Indicate the correct alternatives.

a) I gave the copies to her.
b) I gave the copies to Maria.
c) I gave the copies to Maria.
d) He gave the copies to his colleague.
e) He gave the copies to his colleague.

See Answer

All alternatives are correct because:

It does not use a crasis before personal pronouns of the straight case (she).

The crasis is optional before female proper names (Maria) and before possessive pronouns (yours and hers).

question 33

In which of the phrases below was the crasis used incorrectly?

I. Did you see that?
II. Are you referring to that?

See Answer

Alternative I: Did you see that?

The crase is used before demonstrative pronouns “that, that, that” since the contraction with the preposition a occurs. In this case, there is no preposition, so the use of the crase is incorrect.

In alternative II. there is preposition (refers to + that).

question 34

Indicate the alternatives that have a backstroke error.

a) I stayed up until 2 am.
b) The movie started at 11 pm.
c) The three hours of film went by quickly.
d) I managed to make it through the three hours without falling asleep.

See Answer

Alternative b: The movie started at 11 pm.
The correct one is “The movie started at 11 pm.”, because the backquote is used to indicate the exact time.

In alternative a) the use of the crase is optional after the preposition “until”.

In alternatives c) and d) do not use a backquote, because it contains counted hours and not an exact time. If it was the exact time, then yes, the back was used.

question 35

The two sentences below are correct, one has a backtack and the other does not. Explain.

I. I'm going to Italy on vacation.
II. I go to Venice on vacation.

See Answer

The use of the backquote in these situations can be remembered as follows:

I'm going to, back from, back there! I go to, come back from, back to what?

Thus, in “I'm going to Italy, I'm coming back from Italy.” there is backlash. While in “I'm going to Venice, I'm coming back from Venice.”, there is no backlash.

question 36

The alternative that correctly fills in the blanks is:

I go to field ___ 10am. The football match is scheduled for ___ 11am. So, later we meet. Up to ___ 4!

a) at - at - at
b) at - at - at
c) at - at - at
d) at - at - at

See Answer

Alternative to: at - at - at.
I go to the field at 10am. The football match is scheduled for 11am. So, later we meet. See you at 4!

at 10, at 4 - the back is used in the indication of exact times. However, "Until 4!" (without back-quote) is also correct, because in the indication of exact times, the use of back-quote after the preposition "until" is optional.

for 11:00 - the back is not used after the prepositions after, from, between, to.
