Now and then some trivial argument would break out, and one of them would kill another one, and all the others would detach themselves from the killer as neatly as blood clotting, and they’d consider the case and they’d either excuse him, for some reason, or else send him out to the forest to live by stealing from their outlying pens like a wounded fox. at times i would try to befriend the exile, at other times i would try to ignore him, but they were treacherous. in the end, i had to eat them.
–grendel,
john gardner
what is grendel’s perspective on the people he observes?
a. he thinks they are weak and amusing.
b. he thinks they are brave and honorable.
c. he thinks they are friendly and caring.
d. he thinks they are violent and untrustworthy.

the answer is:  

he is voicing feelings shared by all humans regardless of race.

in paul laurence dunbar's poem "we wear the mask," he replicates the words mask and we to emphasize how people in general -not just black americans- hide their true feelings. he suggests the masks cover people's faces and eyes, which are the main parts that display their emotions. he also thinks people's pain conceal behind those masks, so that they cannot see reality and nobody is able to see one another's sorrow.

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.

21 balloons is the story of professor william sherman's travels.

in 1883, he set off from san francisco for a balloon ride over the pacific and was found a month later floating with 21 balloons in the atlantic ocean. this seemed an astounding feat and everyone wanted to know what had happened.    

professor sherman was loyal, however, and said he would tell his tale first to the western american explorers club in san francisco, of which he was a member. this built up suspense for several chapters before he began to tell of the wonders of his adventures and the amazing island of krakatoa, an island which had just been blown up by a volcano.  

the residents of krakatoa are all millionaires who live under a "gourmet government" of their own devising. we get to see all the incredible adventures that creative people with unlimited resources would create according to the author.
