Like the grassy fields and old pastures....., 后句应该也是名词开头！！所以排除CDE
A：vanishing in the northeastern United States是定语，定语是修饰前面的sandpiper的，定语不是句子基本成分，去掉句子仍然完整，去掉后，就变成sandpiper is a result of ...., 逻辑意思有问题错误
A：and前面用了逗号，就把后面的部分从almost all of which的从句中分隔开了，从而变成了主句的一部分，和will have no effect平行了
be subjected to的subject是动词，意思为使臣服，使顺从；而正确的应该用形容词的subject：subject sb/sth to sth 使经受；使遭受
those of的of错误，因为要表达的不是从属关系，而是standards for sth...
How likely is it NOW that a comet/asteroid WILL STRIKE Earth?
C mentions "how likely a comet/asteroid will be". Nope. The likelihood is something that exists now, not in the future. (That's the definition of "likelihood": How probable does this event seem right now? There's no "future likelihood" here. In the future, the event either happens or doesn't happen.)
D mentions the likelihood (as measured at present) that a comet/asteroid will collide (in the future) with Earth. That makes sense.
The civil rights movement would have benefited from a postwar continuation of the wartime alliance between trade unions and the African American community

D.but also后没中心词和be tied to
E.but also后面差个on
