Question

Each of the participants.............. Willing to be recorded 1) were 2) had
3) has
4) was

Answer 1

Answer:

Each of the participants was willing to be recorded.

Explanation:

Since the starting of the sentence i.e. the subject is "Each" which is singular. Hence by following subject-verb agreement, the verb is also singular.

And "was" is appropriate as the sentence is in continuous tense.

Answer 2

Each of the participants 4) was willing to be recorded.

• We have used was because each is a singular word, and the sentence is in the past tense.
• We cannot use were because each represents singularity.
• Had will not be used here, as it will give a grammatical error and change the literal meaning.
• Has will not be used here, as it will give a grammatical error and change the literal meaning.
