140.    It may be another fifteen years before spacecraft from Earth again venture to Mars, a planet now known to be cold, 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), 可是c)中用了将来时态，似乎更好些。虽然后面的know as being cold 不是很完美。 c)为什么错? 恳请指点。

以下是引用tianwan在2004-1-29 19:46:00的发言：

偶什么情况都想了一遍，就是没有考虑到这一点

”known as being 必错“？？ 或者" as being必错"？？
