Question

They (say) ______ that they (complete) ______ the project a week from today.

Answer 1

Answer:

They  __said____ that they  __had completed____ the project a week from today.

Explanation:

The statement clearly mentions that it is about an event of the past. So, the words SAID and HAD have been used accordingly to give a direct meaning.

A sentence is considered to be grammatically correct, if the subject and verb are both singular or plural. To be precise, the subject and verb must agree with one another in their tense.
