同意楼上观点
with在这里却是有可能引起奇异
which were好些

如果用with的话，容易引起歧义，因为可能修饰的是spacecraft，也可能是the shuttle and earlier spacecraft，
而earlier spacecraft是单数，which were就避免了这一歧义。

with可以修饰the shuttle and earlier spacecraft整体，也可以单独修饰spacecraft

gmatziyu

with会引起歧义呢？？不明白。。。

哎，我开始一看题也选错了，不过猜测应该是因为With修饰上会产生歧义吧，D中的which后面接了were可以避免这种歧义
