No. "HAD" is not required here.. "HAD" needs to be used only when the action referred to happens before some other action. The action referred to here happens after the previous action and hence a simple past tense would suffice. Further, C uses "quicker" which is less grammatically correct than "more quickly" (In my opinion, quicker is more a slang, and hence on the GMAT, "more quickly" should be preferred). Hence the correct answer would be D.

yes... no need for HAD, spot on again abt the quickly vs quicker thing.. dammm im getting outta touch.. keep doing the good work Vik!
Methotrexate, which was originally developed for a single purpose, has proven its effectiveness in several roles, including treating cancer, relieving arthiritis and it is able to dull pain..
1. including treating cancer....... 2. including treating cancer, relieving arthiritis, and dulling pain. 3. including the treatment of cancer, relieving arthiritis, and dulling pain. 4. which includes treating cancer, relieving arthiritis, and it is able to dull pain. 5. which includes treating cancer relieving arthiritis, and dulling pain..
I got this one from Kaplan and it is a simple parallel consturction question, so I am going to spare u the trouble of solving it. 2 and 5 both solve the parallel consturction error and because 5 uses "which includes" which is singluar and doesnt go with the plural "roles", the answer is 2.
Now my question is this.. Suppose 5 was rephrased as
5. which include treating cancer, relieving arthiritis, and dulling pain.

No wait.. maybe you were right.. the "had" can be used because of the mention of "three decades". So, we are comparing this activity to the end of "three decades", which both happened in the past.. So, I think "HAD" can come here.
what say?
Btw, what is the correct answer? can someone post it soon?
I found this question on Powerprep and I am surprised with the answer. Can anyone please explain. I haven't posted the answer.

what would the correct answer be?????

Both the ans are right Vikram. Brilliant! The ans are B & D.
.. and to your q in my opinion "which include treating cancer, relieving arthiritis, and dulling pain." would be right too as 'which' correctly points out to the noun 'roles' and it is an additional information which can also be done without.
.... as 'which' correctly points out to the noun 'roles' and it is an additional information which can also be done without.
Yeah, I was of the same opinion too.. Given that both the answers are correct, then as per what Kaplan says "if two answers seem correct, go for the more consise answer".. So, with that argument, "including" would still win!!!
The correct ans is D. It's written that In choices B and C the preposition for is used unidiomatically. I am not sure why is that so. I had picked B.
Hi,
IMHO, the problem with "for" , and option B , is "creates conditions for the trees to grow" ..is incomplete and ambiguous. For "for" to be correct here, the sentence should have been "creates favorable conditions for the trees to grow".
I am not sure, but perhaps the idiomatic usage refers to the idiom "create conditions that.." ...though I couldn't really find this idiom in Manhattan, so can't be sure about this.
I think its B, butall of which creates conditions isn't this wrong? OA pls
Hi,
all of which creates conditions is correct, because its the complete set of conditions that together create favorable conditions for trees to grow. if the sentence is changed to all of which create conditions , then this would indicate that all the instances separately support the growth of trees.
can any1 help me out on this one..plz provide a adetailed explanation...

thnx Sumit
The answer is C.
"routes for" is unidiomatic. Hence A is out. "routes" is plural and hence "monitors" isnt correct. Hence D and E are out. B is incorrect as it uses the wrong idiom "as many".

thnx Sumit
think its C - concise, and we are talking abt COUNTS so "monitor" this eliminates D and E, A --> "or of" doesnt sound good.. 'as' is missing as well.. we are down to B & C, so IMO C - less wordy and upto the point? wat say? and wats the OA? is this from Kap 800?

Hey Vikram
Thnx for the perfect and concise explanation.... The explanation I read was inappropriate and I did nt notice the word "routes" - which is plural...

Hi,
thnx, the ans is correct..but refer to the explanation that Vikram has provided. This ques is from OG11 (which i doubt)... :) When r u taking ur GMAT ?
If Dr．Wade was right，any apparent connection of the eating of highly processed foods and excelling at sports is purely coincidental． (A) If Dr．Wade was right，any apparent connection of the eating of (B) Should Dr．Wade be right, any apparent connection of eating (C) If Dr．Wade is right，any connection that is apparent between eating of (D) If Dr．Wade is right，any apparent connection between eating (E) Should Dr．Wade have been right，any connection apparent between eating Both c & d look fine, but why one of them is better ? I feel option c is ok as it maintains the parallelism eating of .and excelling at .

I think I would go with d.
THe choices are clearly down to C and D. However, I find two issues with C. THe Correct idiom to use is "connection between", but C places the word "apparent" between these two. Secondly, C infact is not parallel, as C uses the noun form "eating" as compared to the verb "excelling" while D uses the verb "Eating" to go parallel with the verb "excelling".
... and yeah C is wordy too.... why would u say " connection that is apparent" rather than saying "apparent connection"?? Ofcourse, teh wordy rule can be used only if everything else is ok!
