Michelangelo was the greatest sculptor of the sixteenth century. We admire the products of his genius but we less frequently pause to consider the magnitude of the tasks he undertook, the problems he encountered, and even failures he may have suffered.
 
【正确答案】 A
【答案解析】magnitude量,大小(通常指大的),英文释义为(usually large)size,因此A与之匹配。large amount of大量的,用来修饰不可数名词,但文中的“tasks”是复数,不能选。magnificence雄伟,壮观。hardships困难,苦难。
