Question

priyanka ______ all the questions perfectly . the panel had to select her . ( answer)​

Answer 1

The correct answer is 'answered'.

Priyanka answered all the questions perfectly . The panel had to select her .

It is because we need to place a form of the word given in bracket- answer.

Since the sentence is in the past tense, as indicated by the word 'had' , we need to choose the past form of the word answer, which is answered.

Answer 2

The answer is answered.

Priyanka answered all the questions perfectly. The panel had to select her.

Explanation:

The sentences indicated that the selection has already been done. In other words, it is an action of the past. This took place because of an action that took place before the selection. This implies that such an action is also over. Hence, the verb should be in the past tense form.

The past tense of answer is answered.
