Answer 1

为你解答。
The teacher asked the students （c.if they were interested in dinosaurs）.
老师问同学们是否对恐龙感兴趣。
解释：括号中要填宾语从句部分。选择的标准一是看陈述语序，二是看时态是否一致。
错误的三项分析：
a.when was（语序不对，was要放在主语之后） Albert Einstein born
b.what they will（时态不一致，应为would） do with the computers
d.how many trees they have（时态不一致，应为had） planted

Answer 2

c.if they were interested in dionsaus.

Answer 3

c
定语从句的话要用陈述句的语序 因此排除a ， 前面主句是asked 属于过去式， 所以从句也要用过去式 因此排除b 和d
