Establish the correspondence between the seas and the type to which they belong: pick up the corresponding element from the second column for each element of the first column.

Analysis:

The task is to match the seas listed in the first column with their types from the second column.

The first column lists:
1. White Sea
2. Aral Sea

The second column lists types of seas:
1) internal
2) marginal

Matching:

The White Sea is an inland sea in Russia, located off the southern coast of the Arctic Ocean. It is considered an internal sea.

The Aral Sea was an endorheic (terminal) desert lake in Central Asia. It has shrunk dramatically and is often considered an internal sea or a lake that was once a sea.
