这两道题目中困惑你的答案都错在割裂了句子关系。

204－homes for which they could no longer afford monthly payments - 表明了payments和homes之间的关系；而homes because they can no longer afford monthly payments - payments和homes之间没有任何关系，payments可能指其他东西的payments。当然，从时态上，排除D可能更容易，1973表示过去，can错。

215－C中and that it was impossible to eradicate和that music was perhaps the ultimate expression平行，而从A的逻辑搭配来看，and后的部分是修饰vector of African culture的，所以，and部分改变了句子的修饰对象，从而改变了句意。
