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

1. commodities like aluminum and other metals remain
   
2. commodities like those of aluminum and other metals are remaining
   
3. commodities such as aluminum and other metals remains
   
4. commodities, such as aluminum and other metals, remain
   
5. commodities, like the commodities of aluminum and other metals, remains
   
   答案：E
   我觉得E肯定是错的，remains就用的不对，应该是remain的吧。我当时选的是D。
   是不是答案错了？求指点，感激不尽！！！

主语是market，因为要主谓一致所以用remains。
但是有一点我不明白，为什么不选C呢？like一般不用在句中表举例的啊~~求解答。
要不楼主再对一下答案？

这道题的主语是market，不是recycled commodities，所以谓语动词当然是remains啦
