A.
B. Like any star of similar mass, once the hydrogen in the SunтАЩs core is exhausted, then it expands into red giant and eventually eject.
C. As in the case of any star of similar mass, once the hydrogen in the SunтАЩs core is exhausted, it will expand into red giant, and eventually ejecting.
D. As any star of similar mass would, once the hydrogen in the SunтАЩs core is exhausted it will expand into red giant and will eventually eject.
E. As would be the case of any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into red giant and eventually eject.

Another one for E

ALL others wrongly modify the hydrogen...
The comparison is between similarl stars and the sun.

laxieqv · Answer

B and D are wrong coz they compare " the hydrogen in the sun's core" with " any star"
C is wrong coz the thing " will expand" here is the Sun, not the hydrogen
As some posts in forum pointed out that we use " like" to compare thing to thing, "as" to compare manner to manner. I eliminate A this way.
Finally I pick E.

One cosmological fact for those who feel interested in: Normally white dwaft withdraw the mass from nearby red giant until its accumulative mass is 1.4 mass of the Sun's mass under the influence of gravitational force.

between A and E . Pick E because A uses "Like" . Is the use of "as" the same as "such as"? 
OA?

Most of us chose E.........
could someone explain me what the structure is?

As would be the case of any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into red giant and eventually eject.
1.What the function of " as "?
2.and what the subject of " would be" is
I really in doubt. :shock:

OA is E.

Thanks laxieqv for your nice explanation.

automan · Answer

I discard A and C on the basis of the rules for like and as. B can also be discard because we expect kind of a noun after the comma and there is nothing sembling a noun. Between D and E I choose E. D doesn't have a verb. The instructory phrase doesn't make any sense.
