In lines 74-83, the author discusses people's capacity to accept change. Why does she introduce these ideas immediately before "falling out"?

Hello. You have not specified the text to which this question refers, which makes it impossible for this question to be answered accurately. However, we can consider that the event in which the character "falling out" represents a major change in her life, for this reason, to discourage people's ability to accept changes before that event, presages the character's resilience and her ability to endure the difficulties that the changes in her life would cause, thus proving the author's argument about the capacity to support changes.

we need to see the examples!

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.
