Final answer:
Selecting the correct verb form to complete a sentence in English depends on subject-verb agreement. The provided sentences require a verb that agrees in number with the subjects, but without additional context, it's difficult to determine the precise verbs that should be used.
Step-by-step explanation:
Completing Sentences with Correct Verb Forms
Understanding how to choose the correct verb form to complete a sentence is an essential skill in English grammar. The sentences provided require selecting a verb that agrees in number with the subject. Let's consider some examples using the provided reference information.
For sentence 1, 'Under the table,' a verb referring to a singular or plural subject could be needed, depending on the context which is not given.
For sentence 2, 'The choir usually' should be followed by a verb that agrees with the collective noun 'choir,' which is often considered singular, so a singular verb form should be used.
In sentence 3, 'Some of the actors' suggests a plural verb form since 'actors' is a plural noun, and 'some' indicates a plural quantity.
With the incomplete sentence 4, 'Some of this song,' a singular verb might be required since 'song' is a singular noun, but the excerpt is too vague to determine the exact verb without more context.
Sentence 5, 'Either my brother or my sisters' would typically take a verb that agrees with the nearer subject, in this case, 'sisters,' which is plural.
The excerpt from Chapter 17 provides a key to answers for a different set of questions and does not directly inform the correct verb choices for these sentences. More information is required to fill in the gaps and provide accurate verb forms for the given sentences.
