Read the section "One Free Name Change." Which selection suggests that a person may need to change his or her name for an unexpected reason?

fond of fighting is the answer

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.

i'm thinking it would be when compound subjects are joined by or, nor,either-or, neither-nor.
