7` make sense 的用法?

从石器时代到现代科技,贯穿整个人类社会的工业是一个逐渐发展的过程.答案是A, a good many后面可直接加复数.a great deal只能修饰不可数名词.答案是Aa knowledge of ...某方面的知识,固定用法.international trade国际贸易,固定习语.答案是A.因为宾语从句的谓语是is, 是单数,所以light不能加s; the street light 的意思是：街灯.street 作light的定语.这是名词作定语.答案是A.sands指沙滩,建的是沙做的城堡.同样是名词作定语.答案是C.一样是名词作定语.区别在于make sense 是不及物的,译为“讲得通,有道理”
而make sense of是及物的,译为“弄懂,理解”肯定：It makes sense. 否定：It doesn't make any sense.
再问： 非常感谢 其他的都是 但第4题答案给的是B 第2题为什么不可以选B C
再答： 不好意思，第4题确实是B，我在解析里面也讲的是B，只是手抖写错了。 第二题，a good many/a great many都是直接加复数的，不用of 如果用of，则后面的名词前必须有修饰词，如： a good many books a good many of these books 名词前有修饰词，比如these，才能加of
