参考答案

正确答案：C
解析：文章提到the best room 时，有这样的句子：“The best room was shut up and darkened，with only so much light as could fall through a little heart-shaped hole in the window-shutter，--for except on solemn visits，or prayer-meetings or weddings，or funerals， that room formed no part of the daily family scenery．”可知，窗户并未封住，又光线可以透过，所以A不对。布置应是最好的，而不是家具全部移出，故B不对。此屋只在举行盛典时才打开，即C，所以就不可能是最繁忙的，所以D也不对。
