Explanation:

Question 15

The underlined word is "written". A participle (past participle here) can function as an adjective to describe a noun ("response"). A gerund acts as a noun but "written" is not a gerund. It's not a helping verb or the main verb here. So option C is correct.

In option A, "has" is a helping verb (auxiliary verb) and "completed" is the main verb, showing the difference. Option C has only a main verb ("completes"), option B has a gerund ("completing"), option D has only a main verb ("completed"). So A shows the difference between a main and helping verb.

In the sentence "The students were prepared for the presentation", "were" is a helping (auxiliary) verb and "prepared" is the main verb (past participle used as a main verb in passive voice - like "were + past participle" structure). So it has a helping verb and a main verb, option B is correct. Option A is wrong as there's a helping verb. Option C: no infinitive. Option D: "were" is a linking verb? No, here "were prepared" is passive, "were" is auxiliary. Wait, maybe "were" is a linking verb? Wait, "prepared" as an adjective: "The students were prepared (adjective) for the presentation." Then "were" is a linking verb. But the options: option B says "helping verb and main verb", option D says "linking verb and a description". Wait, maybe the intended answer is B. Wait, "were" as auxiliary (helping) verb with "prepared" as main verb (past participle). So B is correct.

Answer:

C. It is a participle describing a noun.
