Piyush,
What strategy do you suggest for RCs like this in which the content is nothing but a jargon to the reader? This RC mentions some business related stuff, which I was not able to comprehend at all in my first reading(or may be second reading too) so I kinda skipped most of the details and hence took long long time to figure out the answers(most of which might be wrong as well, no wonder!)
Please help .
