【题文】_____ some people regard as a drawback is seen as a plus by many others.A. WhetherB. WhatC. ThatD. How

步骤 1：分析句子结构
句子的主干是“_____ is seen as a plus by many others”，其中“_____”需要填入一个引导词，这个引导词后面的部分“some people regard as a drawback”是作为主语的从句。
步骤 2：确定引导词
根据句子结构，我们需要一个引导词来引导主语从句，同时这个引导词在从句中充当宾语。在选项中，只有“what”可以作为引导词，并且在从句中充当宾语。
步骤 3：验证选项
将“what”代入句子中，句子变为“What some people regard as a drawback is seen as a plus by many others”，句子结构和意义都正确。
