What does the word 'date' most likely mean, as it is uits in this sentence! When I was taking my history test, I remembered
everything about the Battle of Gettysburg except the date
O A Companion at an event
OB. Social appointment
C. When an event occurred
O D. Fruit of a palm tree

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.
