the idea behind comparative advantage reflects the possibility that one party:

may be able to produce everything relatively more efficiently than another party.

may be able to produce something at a lower dollar cost than another party.

with an absolute advantage in producing two different may export goods both of those goods to the other party.

may be able to produce something at a lower opportunity cost than another party.

Explanation:

For the first question, comparative disadvantage means a higher opportunity cost in producing a commodity. Trade allows importing it at a lower opportunity cost than domestic production, so gains are still possible. For the second question, comparative advantage is defined by lower opportunity cost in production relative to another party.

First question: it can still gain from international trade in that commodity, by getting it at a lower opportunity cost than if it produced it domestically.
Second question: may be able to produce something at a lower opportunity cost than another party.
