单选题 Woman: What did the teacher want you to do?
Man: She asked me to finish doing the assignment in ten minutes.
Woman: In ten minutes? That would not be a piece of cake. But did you say "yes"?
Question: What does the woman mean?

A、 The man could be awarded a piece of cake if he can finish the work in 10 minutes.
B、 The woman doubted if the man could finish his assignment in 10 minutes.
C、 The assignment was too difficult to finish in t0 minutes.
D、 A piece of cake cannot represent the value of the assignment.

【正确答案】 C

【答案解析】[解析] 此题考查对会话中习语的理解。a piece of cake的字面意思是“一块蛋糕”，其含义与汉语的“小菜一碟”类似。此语用来比喻事情的“轻而易举”或“容易，简单”。题句中说的是不可能十分钟完成作业，所以C项为正确答案。
