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
PREP 的解答是：A.and前后不对称，前面是完整句子，后面是一个介词短语。
B.correct；its 60 square miles of water thought to be…做been considered的伴随状语做补充说明逻辑最合理。
LZ 的疑问是： 对于A选项整个句子，将开头中以WITH为首的介词短语还原位置，则原句变成： Jupiter's moon Europa has long been considered far too cold to support life, With surface temperatures estimated at minus 230 degrees Fahrenheit （and with 60 square miles of water thought to be frozen from top to bottom）.
