如何理解multiple choice questions

问：《新概念英语》课后练习题型为：Multiple choice questions  多项选择题。可给出的答案是清一水的单项选择。为什么？那么，单项选择题该如何翻译？谢谢！
答：你对multiple choice的意思误解了。multiple choice questions（多项选择题）不是指“所选项”，而是指“待选项”。请看有关英语词典对multiple choice的解释：

In a multiple choice test or question, you have to choose the answer that you think is right from several possible answers that are listed on the question paper.
《朗文当代英语词典》第4版对multiple choice的解释是：

《牛津高阶英语词典》对multiple choice的解释是：
