Question

What will you do when you are thirty years old? (Use Simple future and Future perfect tense)

Answer 1

Explanation:

We use the future perfect simple (will/won't have + past participle) to talk about something that will be completed before a specific time in the future. ... (meaning 'at the end of this period') to give the time period in which the action will be completed. I won't have written all the reports by next week.
