如果依庖丁解牛所说，该题中有主谓宾，而比较的是主语，那么do应该补出， 而答案中无do, 难道原因就是两个谓语动词?

You got the point I guess Coz if there is a do, it may refer to the second verb gain or the both two verbs require and gain together, the diction making the sentence ambiguous and awkward.

 因为比较的是两个动词：require和gain，所以后面的一个do来指代谓语不合适，就省略了

赞一个。
