With surface temperatures estimated at minus 230 degrees Fahrenheit, Jupiter's moon Europa has long been considered far too cold to support life, and with 60 square miles of water thought to be frozen from top to bottom.
A. Europa has long been considered far too cold to support life, and with
B. Europa has long been considered far too cold to support life, its
C. Europa has long been considered as far too cold to support life and has
D. Europa, long considered as far too cold to support life, and its
(B)
E. Europa, long considered to be far too cold to support life, and to have
这题有两个语法点,看来你已经理解了前面一个。那么我们可以把句子简化成With high surface temperatures , Europa has long been considered too cold to support life, (?) water thought to be frozen. 后面这半句我们按照大意补充起来应该是because its water has been thought to be frozen. 由于这里省略了主语Europa,所以提示我们考的是parallelism平行结构,这半句的作用是补充说明主句、是伴随性的,可以省略and和has been 。

这样逻辑上也更讲得通。
