Recent finding lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies estimated to exit in the universe.

a. that a black hole lies at the center of the Milky Way and of

b.that a black hole lies at the Milky Way's center and

c.that there is ablack hole lying at the milky Way's center and

d.of a black hole lying at the Milky Way's center and

e.of a black hole that lies at the center of the Milky Way and of (a)

为什么这题是a

不懂a选项and 后面的of

是that a black hole lies at the center of the Milky Way and (that a black hole lies at the center) of 的意思吗

但是这样的意思怎么感觉怪怪的

that 不能省,there is 不简洁, B's A一般表示有生命的东西,   A of B 表示无生命的东西

还有A+介词+B比 B'A更能表达清楚,所以同等情况下,A+介词+B优先.

比如:the ...of France>France's...

我觉得是that a black hole lies at the center of the Milky Way and ( at the center) of

所以排除B,C,D,E,  选A   仅供参考

不太明白这句话的意思

这句话是说最近的发现强力支持(1)有个黑洞在Milky Way的中间(2)有100 billion galaxies存在宇宙

还是说(1)有个黑洞在Milky Way的中间 (2)黑洞存在100 billion gaaxies里面觉的第二个说法很不合理

但是又不知道A选项and of 的 of 是哪来的
