这道题目是个比例问题，制作一罐orange juice需要的水和浓缩汁比例为1：3

200罐6盎司的orange juice总共1200盎司，按照比例，浓缩汁占四分之一就是300盎司，每罐浓缩汁12盎司，所以总共需要300除以12等于25罐。

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

答案:C

这道题目是这个意思：

M这个人做一道可供4个人吃的菜需要1.5 cup的通心粉，问根据这个菜谱，M这个人下一次准备这道菜的时候需要多少cup的通心粉？

1）下一次，M准备这道菜，可供食人数和上一次的一样。

2）上一次，M用了6 cup的通心粉。

这里需要说明一下，题目一开始只给出了比例，并没有说有上一次M一共给多少人做了饭。条件2给出了总共用了6 cup，按照比例，则上一次总共有16个人。条件1说，下一次和上一次人数一样多。所以下一次还是用6 cup的通心粉。

两个条件缺一不可。
