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.

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
E. Europa, long considered to be far too cold to support life, and to have
这题答案选B，但我的疑问是难道its前面不应该有and么？我记得两个单独的句子间要有连词连接的啊。

我之前搞错了，现在修改过了，问题依然存在啊

nemiah

独立主格，如果有and， thought 前面要加be动词。

连词是连接两个句子的，A变成了前面一个句子，后面一个独立主格结构，显然不对

划线句前面的逗号和中间的逗号看做一个插入语，中间直接无视，这样就只有its能接上前面

如果无视的话那么it's指代什么？而且第一个逗号后面明显是两个独立的句子，怎么能没有连词呢？
