25. The father, as well as his oldest son, ___ in the plumbing business. Neither his daughter nor his other sons __ interested in the business. Which of the following options correctly completes the sentence above?

a. Is, is
b. Are, are
c. Are, is
d. Is, are
I think C

No.

The father and his son are plural subjects, two of them. The daughter and the other sons are more than one, also.

Hey Reed, so the answer should be B.

i think its D

To determine the correct option, we need to understand the subject-verb agreement in the sentence.

In the first part of the sentence, we have "The father, as well as his oldest son." Here, we have two singular subjects connected by the phrase "as well as." When two singular subjects are connected by "as well as," the verb should agree with the subject closest to it. In this case, the closest subject is "his oldest son," which is singular. Therefore, the correct verb form is "is."

In the second part of the sentence, we have "Neither his daughter nor his other sons." Here, we have a negative construction using "neither... nor." When using "neither... nor," the verb should agree with the subject closer to it. In this case, the closer subject is "sons," which is plural. Therefore, the correct verb form is "are."

Now, let's look at the options:

a. Is, is - Incorrect. The first verb "is" is correct, but the second verb should be "are" to agree with "sons."

b. Are, are - Incorrect. Both verbs should not be in the plural form since only "sons" is plural.

c. Are, is - Correct. The first verb "are" agrees with "sons" (plural) and the second verb "is" agrees with "oldest son" (singular).

d. Is, are - Incorrect. The first verb should be plural to agree with "sons."

Hence, the correct option is C: Are, is.
