One of the most important questions they had to consider was ______ of public health. A．what B．this C．which D．that

Answer 1

D

试题分析：考察代词。本句中的系动词was后面不是一个完整的句子，所以不能使用AC项。That指代前面的名词problem，后面有定语修饰，表示特指。句意：他们不得不快乐的问题之一就是公共健康的问题。故D正确。 点评：代词的词义辨析考查的较为细致：One 指代可数名词单数，表示泛指；其特质形式为the one。It指代上文出现的同一事物；that指代可数名词单数，或者不可数名词，后面必须有定语修饰。起复数形式为those，同样后面也应该有定语修饰。
