Answer:
The way it looked when it was new is the correct answer.
Step-by-step explanation:
In the excerpt, the author mentions that the house is "familiar" to him and that it has been an object of curiosity for him since he was a boy. He also mentions that it is "difficult to imagine the bright novelty with which it first caught the sunshine," suggesting that it is difficult to imagine how the house looked when it was new and first caught the sunshine. The other answer choices do not accurately reflect what the author suggests is difficult to imagine about the house.
