<u>Answer:</u>
Comfortable
<u>Explanation:</u>
One type of the adjectives is predicate adjective. A predicate adjective is an adjective which follows a linking verb and modifies or refers back to the main subject of that linking verb.
It usually is used just before the noun it modies.
Here in this example:
'Penguins seem comfortable in the coolest habitats', comfortable is the predicate adjective which follows the linking verb 'seem' and modifies the noun.
The story strongly suggest themes of human relationship and (possibly) a heist or job that seems to be involved.
It would be past tense because when you say something occurred you are saying that it has already happened
