PREP DS 55？

Malik's recipe for 4 servings of a certain dish requires 1 cups of pasta.  According to this recipe, what is the number of cups of pasta that Malik will use the next time he prepares this dish?b

(1)  The next time he prepares this dish, Malik will make half as many servings as he did the last time he prepared the dish.

(2)  Malik used 6 cups of pasta the last time he prepared this dish.

选的A，答案为C

题目只能说明准备一份需要多少pasta，但问的是下一次要用多少，必然需要知道下次要做几份

（1）只说了下一次跟上一次的关系，但还是不能说明到底是多少的

（2）就补充了这个信息

哦，谢谢，清楚啦
