Use the present tense of the verb to complete the following sentence. they each 10 laps a day. swam am swimming swim have swum

C). Swim.

Explanation:

As per the question, the present tense of the verb that would complete the given sentence would be 'swim' as it exemplifies a regular action and follows the tense(present) and subject-verb agreement(plural verb 'swim' with the plural subject 'they').

Option A is incorrect as it offers a past form of the verb while option B falsely proposes 'am' as a helping verb which would be inappropriate with the pronoun 'they'. Option D is incorrect as the sentence exemplifies a regular action that could not be stated in the present perfect tense. Therefore, option C 'swim'(present indefinite tense) would best complete and accomplish the meaning of the sentence.

A simple sentence consists of only one clause. A compound sentence consists of two or more independent clauses. A complex sentence has at least one independent clause plus at least one dependent clause. A set of words with no independent clause may be an incomplete sentence, also called a sentence fragment - via Wikipedia
