Describe how circumstances would affect a person’s identity development (crisis, commitment, diffusion, foreclosure, moratorium, achievement). i don't really understand what is it asking i know the first part but i am having trouble with what it means in the parentheses.

The parenthesis are just giving you examples about developments in a persons life. Like a big crisis could mean that the person would get very depressed.

comfortable

explanation:

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.
