Throughout Chapter 4, we learn that both Helmhotz Watson and Bernard Marx feel like outsiders in their communities. Huxley tells us on page 67, "What the two men shared was the knowledge that they were individuals" and that this individualism causes each of them some discomfort, or even unhappiness. What do you think Huxley's message here might be? What is he trying to tell us when he shows us that individuality and unhappiness might be linked?

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.

dont have the answer

in the following paragraph, the fourth sentence the correct answer is: three personal subject pronouns

”she was embarrassed when she found that they had been put back on the shelves…”

a   subject pronoun is a personal pronoun. i, you, he, she it, we, they.  

in the sentence it can be observed she, used twice and they used once. is for this reason that is a three personal subject pronoun sentence.
