问题 If a needle is thrown ______ on a sheet of paper ruled with lines, how often can it be expected to fall on a line?

选项 A、on purpose
B、with accuracy
C、at random
D、according to one’s own will

答案C

解析 习语搭配A on purpose故意;B with accuracy正确地;C at random随意地;D according tO one’s own will按照某人自己的意愿;而本句意为:如果把一个针 ______ 扔在一张用尺子画上许多条线的纸上,那么这个针正落在一条线上的机率是多大?既然是问概率,那么应是随机地去做某事;因此答案应为C。
