Answer:
1. C. It was unfinished. He built it himself, but there were cracks in the walls and no chimney when he moved in
2. B. He got into a routine at the cabin, which is the exact thing he tried to escape from by moving to the woods
Explanation:
1. When Henry Thoreau Walden moved into the woods, his house was still uncompleted without plasterings on the wall nor a chimney to keep him warm. The house at that point was mainly a defense against the rain because it was not fanciful. It was rather simple, clean, and airy.
2. Thoreau left the woods for the exact same reason that he came in which was so as not to get into a routine in life. According to him, he got into the routine of moving from the pond to his cabin. He realized that he had several other lives to live, and so he went to live them.
