Use of "if" wrong in A , B and E
between C and D
D looks parallel and correct
accept and sailed..

Seems like i made a blooper....
with all the sentences, there is a modifer which modifies columbus.
With options A, C and E, the sentences are awkward. "rather than....was flat"....columbus was sent. It should either be..."rather than...was flat"....the king and queen sent columbus....
C and D show correct intent. However D uses rather than while C uses instead of . Dont remember the rule but "rather than" seems correct
answer should be d as kunal pointed,use of if is wrong and Rather than is more preferable than instead of in gmat.
sauvata Saysanswer should be d as kunal pointed,use of if is wrong and Rather than is more preferable than instead of in gmat.
Hi Kunal
Can you please tell me the reason why usage of IF is wrong in A, B and E
My thumb rule.. use whether when "or not" is also conveyed if otherwise
if he could reach India by sailing west ( or he could not reach)
2 options .. hence use of "if" is wrong.. use whether here.. :)
To add to this, "instead of" is generally used for joining nouns and "rather than" is used for phrases that contain verbs. I read this fact somewhere but I am not 100% sure on this. Can some one verify this ? 
sandy_venkat SaysThe answer is E. Its a direct case of violation of the parallelism rule. How items.... should be logically connected with how frequently... In D, we have the 'how..' but the ending is messed up. It goes into a different tense. E puts it correctly. Am i right??
Folks just wanted to give everybody here a heads-up Once we move to the new forum, I will be closing this thread down. It's anyway gotten way too long.
Once we move to the new section, what I'd like you to do is create a thread for each problem that you want to discuss. The title should follow the format "Source" "Type" "Question Number" "Misc information"
So thread titles will now look like "OG12 DS #247" or "TIME PS #7 Book5Pg38"
Why I am doing this
In this thread alone there are a ton of good problems that most likely nobody is ever going to read because it's buried too deep. And that's a serious waste. The new format allows somebody to more efficiently use the tags to find a particular solution rather than reposting the question.
As always open to suggestions and discussions

Target 750 SaysI am not really sure of the idea. Although there may be tons of material buried in this thread, making a new system where all problems will have a unique link won't be an easy way out too. I am thinking about a situation where we have more than 1000 problems then one may be searching each thread .... let me know if I may have misunderstood your idea....
If you haven't seen PG's beta version - it's more StackOverflow in nature where each query can have a top-rated answer. So if somebody posts a brilliant answer to a particular problem, everybody can see what a great answer looks like as well as other possible solutions and discussions around that problem only.
I realize that it is easy to just post in a particular thread but there's no guarantee that somebody will answer or give the best solution at all times. Plus they lose out on the discussion around that problem.
The reason I am insisting on that particular format is because people won't have to search a 1000 problems they will have to just search for the thread that contains those tags.
Certainly a very good approach! Humble suggestions from my side:
1>Addition of a timer in each thread.
2>When posting a question, the user may be given the option to mark the OA.
