You are right.

Yes, you are correct. Sentence B "Each of the 14 groups are going to contribute an item to the auction" contains an error in subject-verb agreement. To identify the error, we need to understand the concept of subject-verb agreement.

In English grammar, subject-verb agreement means that the subject of a sentence (the doer of the action) must agree with the verb (the action itself) in terms of number. That is, a singular subject requires a singular verb, and a plural subject requires a plural verb.

In sentence B, the subject is "each of the 14 groups," which is a singular subject because "each" refers to each individual group. Therefore, the correct verb form should be singular, which is "is," not "are."

To identify the error, you need to examine the noun phrase that serves as the subject of the sentence and check if it is singular or plural. In this case, "each of the 14 groups" is a singular noun phrase, so the correct verb should be singular as well.

Therefore, the correct version of sentence B should be: "Each of the 14 groups is going to contribute an item to the auction."

Remember, subject-verb agreement is an important grammatical rule, and paying attention to it can help ensure your sentences are clear and accurate.
