Answer 1

Answer:

They will have swum in the pool.

Explanation:

• The use of future perfect tense occurs when we use actions that will be completed before some point of time in the future.

• Here is a rule that a sentence always has to take to be considered in future perfect tense:

Subject + will/shall + have + V3 (third form of the verb/past participle) + object + { since/for + time }
