B. that
C. who
D. this
题目解答
答案
B. that
解析
步骤 1：分析句子结构
句子的主干是 "we asked the workers about things"，其中 "things" 是先行词，需要一个关系代词来引导定语从句。
步骤 2：确定关系代词
定语从句 "__________ made their work harder to do" 中，关系代词在从句中作主语，且先行词 "things" 是物，因此关系代词应为 "that"。
步骤 3：排除其他选项
A. "what" 不能引导定语从句；C. "who" 用于指人；D. "this" 不是关系代词。
