please check my answer thanks.

Which of the following sences demonstrates correct subject- verb agreement.

1. Elens thinks that five dollars are a lot of money.
2. A number of my friends have bought new cars recently.
3. Each of his sisters go to a different school.
4. Robert's friend Steve, as well as his wife is going to the fair.

I think it's answer # 4

You're right -- #4 it is.

There needs to be an additional comma in sentence 4, though -- after "wife." Then it's clear that the subject is "friend."

Thanks for the help

To check your answer, we'll analyze each sentence to determine if it demonstrates correct subject-verb agreement.

1. "Elens thinks that five dollars are a lot of money."
The subject is "Elens," and the verb is "thinks." This sentence demonstrates correct subject-verb agreement since the verb agrees with the singular subject. However, there is an issue with the verb agreement within the dependent clause, where it should be "is" instead of "are." So, this sentence does not demonstrate correct subject-verb agreement.

2. "A number of my friends have bought new cars recently."
The subject is "a number," and the verb is "have bought." This sentence demonstrates correct subject-verb agreement since the plural subject takes the plural verb.

3. "Each of his sisters go to a different school."
The subject is "each," and the verb is "go." This sentence does not demonstrate correct subject-verb agreement since the singular subject "each" should take the singular verb "goes." So, this sentence does not demonstrate correct subject-verb agreement.

4. "Robert's friend Steve, as well as his wife is going to the fair."
The subject is "Robert's friend Steve, as well as his wife," and the verb is "is going." This sentence demonstrates correct subject-verb agreement since the singular subject takes the singular verb.

Based on our analysis, your answer #4 is incorrect. The correct sentence that demonstrates subject-verb agreement is #2: "A number of my friends have bought new cars recently."
