gwd4-34 这种题都做错,还有什么希望!

Q34:

The market for recycled commodities like aluminum and other metals remain strong despite economic changes in the recycling industry.

    C. commodities such as aluminum and other metals remains

    E.commodities, like the commodities of aluminum and other metals, remains

答案是E, 为什么C不可以? 不是说举例的话总是用such as吗? like总是被排除的吗?

我的理解是：such as作为举例，后边跟的东西应该是包含在such as之前那个名词里的。这道题之前的名词是recycled commodities,如果用such as应该举例说比如Paper之类的，作为aluminum and other metals应该不能被称作是日用品。所以这里用such as表达是不对的
