This sentence contains an error in noun-verb agreement. Since Gabrielle is a name, the verb must be in its third person, singular form in order to correctly agree. The correct form is "wants." The correct choice is, " wants a tattoo of."

This sentence contains an error in noun-verb agreement. The word people should be paired with the word "stand," since it is a plural noun. "Stands" is the third person, singular form of the verb stand. The correct choice is, "The people stand in the lobby as they wait." Note that "stood" is incorrect because it is a tense shift that would make no sense: it would indicate that the people are no longer standing and that any events have already been completed (which is inconsistent with "waiting," which indicates waiting in the present/now).

This sentence contains an error in subject-verb agreement. The correct form of the word "deliver" would be "delivering" in this case as it is functioning as a gerund in the sentence. The only choice that fixes this error is, "She always practices delivering her new comedic material."

This sentence contains an error in subject-verb agreement. The correct phrasing is "The girl is playing in the garden" since the word "girl" is a noun, so it is 3rd person, singular.

This sentence contains an error in subject-verb agreement. The subject, "goals" does not match the verb, "was." In order for these to agree, "goals" either needs to be made singular or "was" made plural. The only choice to fix this error is, "His goal was to become." This is the correct choice.

This sentence contains an error in subject-verb agreement. Since the word "artisan" is the subject (3rd person, singular), the correct form of the word "use" is "uses." This is the only change necessary. The correct choice is, "The artisan uses bamboo in order to create."

This sentence contains an error in subject-verb agreement. Since the subject of the sentence is "we" (1st person, plural), the correct form of the word "give" is "give." Note that "given" is passive, and "gived" is not a word. The correct choice is, "We give gifts to the children."

The definite pronoun "each" should be treated as singular, and its corresponding verb should be conjugated accordingly. In this case the second instance of the word "each" in the prepositional phrase "at each of the universities" creates about as much confusion as the word "universities" (plural). The only answer choice that resolved the subject / verb agreement error uses the auxiliary verb "was."

This sentence uses the wrong form of the verb "buy." In the present tense, the "s" drops off of verbs when its subject is in the third person plural. The correct form is "buy." The answer is, "The parents buy gifts."

Here, we need to match the agreement between the subject and the verb.  'Schoolchildren' are plural, but the true subject is the 'group of schoolchildren', which is singular.  Therefore, we need a singular verb.  Because of the 'at the moment' at the start of the sentence, we need to be in present tense.  Therefore, we need to use the singular verb is.
