Regarding the other doubts people are having..
In the 3rd Q. from sentence correction "is still unable to reach hundreds who are marooned" seems right grammatically. So answer should be A,C and D. You can also find the same para in the following article.
The Telegraph - Calcutta (Kolkata) | Opinion | signs ignored
Regarding the congenital, genetic FIB, both these words fit in. I think the 2nd blank will be the deciding factor here, education fits in better, in my view.
Regarding the usage of round, someone correctly pointed out that all the institutes who have been thinking of 4 and 5 as probable answers might get this wrong. The shop is located round the corner looks rather fishy, I wont be surprised if this indeed is the correct option.
Regarding the institutions, organs FIB- still doubtful.. cant find any plausible rationale completely in favor of 1 answer. The institutes who have gone for the 4th option organs; tradition may have got this one right though.
I, unfortunately, find myself on the wrong side of these mistakes.
Regarding the paragraph completion, I think it would be best to leave the CAT to do the thinking here. If such a rage has been ensuing over the para-completion, it would only be fair to infer that all the options are very close. There might be a few changes in 'em, there's no need to be google-ing for those paragraphs. Especially because, the usage of the word "for" instead of "from" in the Mattancherry Q. seems rather deliberate. People tell me that historically IIM's have always stuck to the actual para but again, CAT has always been full of surprises!
So guys..please hold your horses! Para completion, come Jan 2009, might not look the same!
