446. It may be another fifteen years before spacecraft from Earth again venture to Mars, a planet now known to be cold, （划线部分为 again....to be，不知道为什么不能编辑)
dry, and probably lifeless.
(A) again venture to Mars, a planet now known to be
(B) venture to Mars again, a planet now known for being
(C) will venture to Mars again, a planet now known as being
(D) venture again to Mars, a planet that is known now to be
(E) will again venture to Mars, a planet known now as being

答案是A; 问题是spacecraft是单数名词，谓语动词不是应该与之相匹配么？NN们解答一下吧！
