Final answer:
The correction that should be made to sentence 14 is to replace 'seem' with 'seems'. The correct correction for sentence 14 depends on the subject-verb agreement and pronoun-antecedent agreement within the sentence, which cannot be determined without further context.
Step-by-step explanation:
Sentence 14 in the given question is:
14. The protesters holding that hand-painted sign seem/seems really motivated.
The correction that should be made to sentence 14 is: 2) Replace 'seem' with 'seems'.
In this sentence, the subject 'protesters' is plural, so the verb should agree with it and be in the plural form 'seem'.
The correct correction for sentence 14 depends on the subject-verb agreement and pronoun-antecedent agreement within the sentence, which cannot be determined without further context.
Without the context of sentence 14, it is difficult to determine which correction should be made. Typically, a correction would depend on the subject-verb agreement and whether the sentence correctly uses singular or plural nouns and verbs. In general, if the subject is singular, the verb should also be singular (e.g., 'it grows'), and if the subject is plural, the verb should be plural (e.g., 'they grow'). Similarly, pronouns should agree in number with their antecedents. If the antecedent is singular, use 'it is'; if plural, use 'they are'. Furthermore, the verb 'are' should not be changed to 'be' unless it is part of an infinitive structure or used in a passive voice or subjunctive mood. Lastly, if an action is ongoing, 'being exposed' could be the correct form, but without context, this is speculative. Sentence 14 in the given question is:
14. The protesters holding that hand-painted sign seem/seems really motivated.
The correction that should be made to sentence 14 is: 2) Replace 'seem' with 'seems'.
In this sentence, the subject 'protesters' is plural, so the verb should agree with it and be in the plural form 'seem'.
