VJ, please clarify what trouble you are having with the question. Which choices are you clear on and which choices are you confused about? Thanks.

O.A -A for this question
why option A is correct and E incorrect ?
"each of which "will refer to "reserves" when it should refer to "teeth".
To me even E doesn't look perfect but better than other options

IMO E

Hi,
Can someone please help with this:

When an active tooth in the shark’s jaws is lost or worn down, many spare teeth lie in seemingly limitless reserve, each of which are ready to slide into the appropriate position.
A. When an active tooth in the shark’s jaws is lost or worn down, many spare teeth lie in seemingly limitless reserve, each of which are ready to slide into the appropriate position.

'When' denotes the at the same time; and use of when in this incorrectly signifies that many spare teeth lie in seemingly limitless reserve at that same time an active tooth in the shark’s jaws is lost or worn down. Infact, spare teeth are always there.
Also, each of which should follow by singular verb 'is' not 'are'.

B. Whenever an active tooth is lost or worn down, many spare teeth lie in seemingly limitless reserve in the shark’s jaws, which are each ready to slide into the appropriate position.

Use of 'whenever' is incorrect because of same reason as in A. Also, 'which' is incorrectly modifying shark's jaws.

C. Many spare teeth lie in seemingly limitless reserve in the shark’s jaws, each one of which are ready to slide into the appropriate position when an active tooth is lost or worn down.

Correct use of 'when'
but still 'each one of which are ready' should be 'each one of which is ready'

D. The many spare teeth lying in seemingly limitless reserve in the shark’s jaws, each one of which is ready to slide into the appropriate position whenever an active tooth is lost or worn down.

'The many spare teeth lying in' - use of present continuous verb 'lying' is incorrect

E. In the shark’s jaws, many spare teeth lie in seemingly limitless reserve, each one ready to slide into the appropriate position whenever an active tooth is lost or worn down.

Correct.

this should be (e).

the other four choices all misuse "which" (or "each of which", whose modifier properties are the same as those of "which").
in (a), "each of which" doesn't refer to anything at all (it seems to refer to "reserve", but that doesn't make any sense)
in (b), "which" refers to the shark's jaws (this doesn't make sense)
in (c) and (d), "each one of which" refers to the shark's jaws (this doesn't make sense)

also:
(a) and (b) have the wrong meaning: the placement of the "when"/"whenever" clause suggests that the teeth are only there when another tooth is lost or worn down.
(c) has subject-verb disagreement ("each one of which" is singular, but "are" is plural).
(d) is a sentence fragment.

O.A -A for this question

no way. this must be (e).
where did you get this supposedly official answer?

Probably from beat the gmat or urch.
Better if I not rely on these sources for OA.
Thanks Ron

yes.

technically, we don't even allow problems from other blogs. you MUST be able to cite the PRIMARY SOURCE of the problem.

thanks.

[yinliqiu]

hi, instructors.
(e), as I know "each" can refer to a plural noun which is just before "each". Here each should refer to one of the spare teeth, right? So "each" can actually refer to something very far from itself ?

can someone explain it? thanks in advance!!

[thanghnvn]

I get this right but too long.

I can eliminate B,C, and D in 10 seconds. But it take me 2 minutes or more to realize that A is not logic.

The hardest of the SC is meaning logic. If the sentence contains new words or knowlege new to the test taker, it is hard to realize the illogicness in meaning and this point is the place where the test maker can exploit as much as he/she want.

How can the practice enhance the ability to realize the hard illogicness? experts, pls, advise.

[jlucero]

To answer your question, the most important skill to acquire for longer, more difficult SC questions is to be able to pull away the junk in the sentence. Rather than reading the awful sentence above, you need to be able to pull away the extra stuff in the sentence (adjectives, adverbs, prep phrases and the like) to find the CORE of the sentence (shameless plug: this is the topic of one of our advanced Quest for 750: SC class that we offer semi-frequently).

When an active tooth in the shark’s jaws is lost or worn down, many spare teeth lie in seemingly limitless reserve, each of which are ready to slide into the appropriate position.

vs

When X, some teeth lie in reserve, each of which are Y.

When a tooth is worn down, some teeth lie in reserve? Only when the teeth are worn down? That doesn't make much sense and it's easier to see that when you aren't focused on all the other junk in this example.

Hi,

This is a GMAT Prep Question and i encountered the same today in my practice exam 3 - GMAT Prep 1 (paid version).

Thanks and Rgds

[RonPurewal]

You can actually solve this entire problem using nothing but "which". All four incorrect answers misuse "which".
("Each of which" and "each one of which" follow the same rule as "which".)

[gmatkiller_24]

Hi, Ron:

I got a doubt about the "each" modifier here in choice E

in choice A,B,C,D, " which" is misused and by no means can "which" refer to teeth

in choice E, is " each" serve as an adverbial modifier to expand the meaning of the preceding clause rather than as a noun modifier?

Please clarify, thanks!
