Ahmad, as well as his cousins, ____________ at the sports complex whenever possible.HINT 1swimswimsswimminghave swum

To determine the correct verb form to fill in the blank, we need to consider the subject-verb agreement. The subject of the sentence is "Ahmad, as well as his cousins." The phrase "as well as his cousins" is a parenthetical element and does not affect the number of the subject. Therefore, the subject is "Ahmad," which is singular.

Given that the subject is singular, we need a singular verb to match. The options provided are:

1. swims
2. swim
3. swimming
4. have swum

Let's analyze each option:

1. "swims" - This is the correct singular present tense form of the verb "to swim" for a third-person singular subject.
2. "swim" - This is the plural form and does not match the singular subject.
3. "swimming" - This is the present participle form and does not fit the sentence structure.
4. "have swum" - This is the present perfect tense and does not fit the sentence structure.

Therefore, the correct answer is:

"Ahmad, as well as his cousins, swims at the sports complex whenever possible."
