Which two excerpts best reflect gregor’s isolated condition after his transformation

The question is incomplete as the choices are not given. so, i am giving an assumed answer based on a similar question from another website.the excerpt has been taken from the story - the metamorphosis written by franz kafka. the major theme of this story is 'isolation'.the excerpt which best describes this theme from the story is - "he got into the habit of closely watching it for one or two hours before it was opened and then, lying in the darkness of his room where he could not be seen from the living room, he could watch the family in the light of the dinner table and listen to their conversation—with everyone's permission, in a way, and thus quite differently from before."
