请高人帮忙解析一下
要具体解析，谢谢

Answer 1

C.at which;where
第一个空 at which the bridge is supposed to be built 为介词+which 引导的定语从句修饰the place，此处at which=where.
第二个空where引导的是表语从句。where在从句中作状语。
即the place should be where the cross river traffic is the heaviest.

Answer 2

C，这里涉及到的应该是定语从句先行词的问题，先行词的选择关键看候命动词，比如第一个，build， 第二个是be the heaviest，思考：build the bridge at/in some place, 而第二句（空格后）则是完整的一句话，肯定考虑副词性质的先行词，故C
