Question

【题目】The largest collection ever found in England was one of about 200,000 silver pennies, all of ______ over 600 years old.

A．which B．that C．them D．it

Answer 1

【答案】C

【解析】all of ______ over 600 years old句中没有谓语动词，主语与前面一句不同，中间没有连词，故判断为独立主格结构，空格处替代前面的名词silver pennies，故选them，相当于and all of them are over 600 years old。
