正确答案D。
定语从句连词的选择
1，看从句少什么成分，决定用关系副词还是关系代词，这题的从句有了主谓，而谓语是被动语态，不能有宾语了，所以，要用关系副词。
2，再回头看先行词，决定用具体哪一个关系词，这题的先行词是age，表时期，
3，两者结合，选择when/ in which.
再如：
This is the factory __we visited last year.从句少了宾语，用that/which
This is the factory __we workted last year从句不能接宾语了，workted是不及物的，用where.
第二题问题他们回答得都很清楚了，
能帮到你就行。

本题应选D，when 指代in an age
which用于非限定性定语从句，如：......，which..... 的形式
其他大多数情况用that
但根据题目不同也有不同

关系副词when=in which，在从句中充当时间状语说明age。在口语中关系副词常用that代替，有时还省略。例：I don't like the way he talks.

D 时间状语从句
只用which
1 关系代词作介词宾语，即 介词+关系代词，指物只能用which
Last night I had a dream in which I became a Nobel Prize winner.
2 非限制定语从句中，指物只能用which， 亦可指整个前面的句子。
He reads English every day, which does good to his English study.

只用that
1 先行词为不定代词: one much everything all any ...
2 先行词被形容词最高级所修饰
3 先行词被序数词所修饰
4 先行词由only ,just ,very, right等修饰
5 在以which 开头的特殊疑问举重，避免重复用that.
6 先行词在从句中担任表语，从句的关系词用that.

D
in an age是一个时间，所以用when修饰
which在句子中做成分，而that不做成分，这是最简单的判别方法。

选D，时间定语从句
that与which两者都可指物，常可互换。其区别主要在于：

1. 引导非限制性定语从句时，通常要用which。如：She received an invitation from her boss, which came as a surprise. 她收到了老板的邀请，这是她意想不到的。

2. 直接放在介词后作宾语时，通常要用which。如：The tool with which he is working is called a hammer. 他干活用的那个工具叫做锤子。

3. much, little, none, all, few, every(thing), any(thing), no(thing) 等时，通常用that。如：There was little that the enemy could do but surrender. 敌人无法,只有投降了。All [Everything] that can be done must be done. 凡能that can be done must be done.

4. 当先行词有the very, the only, the same 等修饰时，通常用that。如：This is the only example that I know. 我知道的例子只有这一个。Those are the very words that he used. 那是他的原话。

5. 当先行词有形容词最高级或序数词(包括last, next等)等修饰时，通常用that。如：。如：This is the best dictionary that I’ve ever used. 这是我用过的最好的词典。The first thing that you should do is to work out a plan. 你应该做的第一件事是订个计划。

6. 当关系代词在定语从句中用作表语时，通常用that。如：China is not the country (that) it was. 中国已不是过去的中国了。

7. 当先行词是一个既指人又指物的并列词组时，通常用that。如：They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。他们谈论了使他们印象最深的人和事。

8. 当要避免重复时。如：Which is the course that we are to take? 我们选哪门课程？
