What are the answers

To determine the correct subject-verb agreement in the given sentences, we need to identify whether the subject is singular or plural, and then choose the appropriate verb form to agree with the subject.

For the first question, sentence A ("The dog and the cat is a popular domestic pet") is incorrect because it uses the singular verb form "is" with a plural subject ("the dog and the cat"). The correct form in this case is sentence C ("Dogs and cats are popular domestic pets"), which uses the plural verb form "are" to agree with the plural subject.

For the second question, sentence A ("Each of the singers are off key!") is incorrect because it uses the plural verb form "are" with the singular subject ("each of the singers"). The correct form is sentence B ("Each of the singers is off key!"), which uses the singular verb form "is" to agree with the singular subject.

For the third question, a compound sentence is a sentence that consists of two or more independent clauses joined by a coordinating conjunction (such as "and," "but," or "or"). Sentence A ("We wanted to travel over the mountains, but our little car could not make the grade") is a compound sentence because it has two independent clauses ("We wanted to travel over the mountains" and "our little car could not make the grade") joined by the coordinating conjunction "but." Sentence B ("Even though we wanted to travel over the mountains, our little car could not make the grade") is not a compound sentence because it only has one independent clause.
