Answer 1

Answer:

He shall correct it by the end of next week.

Answer 2

He will correct by the end of next week.

He will have corrected by the end of next week.  

Explanation:

• The future tense denotes something that is to be done in the coming times.

• The simple future tense is written through the help of an auxiliary verb and the present tense form of the action verb.  

• In the given sentence the action verb is correct. In the simple future tense the auxiliary verb 'will' is joined before correct  

• For future perfect tense an auxiliary + have + action verb is used. So for the given sentence will, have are added before the past participle form of the verb.
