PLEASE HELP ASAP

A man added 2 gallons of water to a fish aquarium. He realized it was too full and needed to bring the water level back down. How could the man bring the water level back to its previous level? Select three that apply.

Group of answer choices

Drain 2 gallons of water from the aquarium.

Increase the amount of water by 2 gallons.

Let 2 gallons of water evaporate.

Fill 2 old milk gallons with water and dump them into the pool.

Let the fish splash out 2 gallons of water

Add 2 gallons of water with a hose

#1 works, but it is not the only choice.

There are three others which will (maybe) work, but only one is practical.
