Understanding Subject-Verb Agreement in English Sentences

Explanation:

In the first sentence, 'Carol' is a singular subject, so the verb 'wish' should be changed to 'wishes' to agree with the subject.

In the second sentence, 'both Cratchit and Fred' is a plural subject, so the verb 'wish' is correct in its plural form.

In the third sentence, 'both Cratchit or Fred' is an incorrect subject. It should be 'both Cratchit and Fred' to match the verb 'wishes' in singular form.

In the fourth sentence, 'both Cratchit and Fred' is a plural subject, so the verb 'wishes' should be changed to 'wish' to agree with the subject.

Learning more about Verb agreement: In determining subject-verb agreement, the compound subject 'both Cratchit and Fred' correctly pairs with the plural verb 'wish'. The correct sentence is 'In A Christmas Carol, both Cratchit and Fred wish Scrooge a merry Christmas.'
