Objects that blow into a swimming pool or that are dropped into the pool by swimmers need to be removed. The objects include foam cups, keys, and coins. Which of the following explains a useful method for removing some of the objects?

• The keys and coins are less dense than water, so they can easily picked off the bottom of the pool by divers.

• The foam cups have the same density as water, so they can be crumbled up for removal by the pool filter

• The foam cups are less dense than water, so they can be removed from the surface with a pool cleaning net.

• The keys and coins have the same density as water, so they can be washed away when the pool is drained.
