The Sun, which is 400 times larger than the Moon, is also 400 times farther away from Earth, so the Sun and the Moon have the same apparent size in the sky. Thanks in Advance. The Sun, which is 400 times larger than the Moon, is also 400 times farther away from Earth, so the Sun and the Moon have the same apparent size in the sky. Here, is also serves a semantic purpose. It implies that one aspect of the sun -- that it is 400 times larger than the Moon -- does not tell the WHOLE STORY. The sun IS ALSO 400 times farther away from Earth. The RESULT is that the Sun and the Moon have the same apparent size in the sky. Another example: Mr. Johnson, my math teacher for the past two years, IS ALSO my soccer coach. Here, one aspect of Mr. Johnson -- that he has been my math teacher for the past two years -- does not tell the whole story. Mr. Johnson IS ALSO my soccer coach. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.

Eliminate A and E. Does this mean that so is not serving as a coordinating conjunction in choice (B)? Would (D) be correct if the comparison ended with only Moon or Moon does (.... the Sun has the same apparent size in the sky as the Moon or should it be Moon does?

Appreciate your quick reply. Can you comment on the choice (D) changes I suggested? Thanks! Master | Next Rank: 500 Posts Joined 01 May 2012 Posted: 122 messages Upvotes: 3 Eliminate A - reason wrong usage of but also Eliminate E - after the comma no subject fight is between B , C and D while all the three have shortcomings , I say shortcomings because it's not one we could solve only by GMAT rules a bit of reasoning is needed . Eliminate D - usage of moon's is ambiguos or not GMAT ish We are left with C and B Eliminate C - wrong usage of cause and effect saying "Apparent size caused the Sun to be 400 times X and 400 times Y " absolutely wrong We are left with B as GMATGuruNY said not so elegant but got to go with it.

But in the above example: Mr. Johnson, my math teacher for the past two years, IS ALSO my soccer coach. "my math teacher for the past two years" is a non-essential clause. Shouldn't it be the essential clause? Mr. Johnson who is my math teacher for the past two years IS ALSO my soccer coach. Legendary Member Joined 20 May 2008 Posted: 1404 messages Followed by: 2 members Upvotes: 18 I like this question very much. in SC, we alway face at least 2 answer choices which are correct both logically and grammarticaly such as B and D in this case. one answer choices is considered wrong because it is not considered the intended meaning. we have to use common sense to realize this incorrectness. D is not wrong at all. But the intended meaning here is clearly B. if D stand alone, it is correct and logic but if it stand beside B, the intended meaning is B not D and D is considered distortd meaning. the matter I said is core thinking of gmat. I wish gmat experts to discuss more of this point. Thank you Junior | Next Rank: 30 Posts Joined 15 Feb 2012 Posted: 27 messages Upvotes: 1 Hi, Pls. tell why the mentioned sentence is wrong. "Four hundred times larger than the Moon and 400 times farther away from Earth, the Sun has the same apparent size in the sky as the Moon's." Woun't it (moon's) refer to the moon size which is compared with the sun size? And i dont think there is some meaning issue here. Pls. cooperate and resolve my confusion.

Sometimes the second verb is omitted, but its presence is still implied. In your post above, the sentence in red is incorrect. It conveys the following meaning: I have the same pen as your pen [has]. The verb in brackets is omitted, but its presence is implied. The resulting meaning is nonsensical, implying that YOUR PEN HAS the same pen as I HAVE. Correct: I have the same type of pen as YOU. Conveyed meaning: I have the same type of pen as you [have]. Another case: Correct: John attends the same school as Mary. Conveyed meaning: John attends the same school as Mary [attends]. The verb in brackets is omitted, but its presence is implied. Incorrect: John attends the same school as Mary's. Conveyed meaning: John attends the same school as Mary's [school attends]. The words in brackets are omitted, but their presence is implied. The resulting meaning is nonsensical, implying that MARY'S SCHOOL ATTENDS the same school as JOHN ATTENDS. Answer choice D in the SC above: The Sun has the same apparent size in the sky as the Moon's. Conveyed meaning: The Sun has the same apparent size in the sky as the Moon's [size has]. The words in brackets are omitted, but their presence is implied. The resulting meaning is nonsensical, implying that THE MOON'S SIZE HAS the same apparent size as THE SUN HAS. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.
