from he lecture i understand that to find out the right answer choice for weaken question, i need to keep two thing in my mind
1. the ans choice is that , which is an assumption and not seen in the premise which is missing from the premise,
2. the ans choice is that which if we add in premise the conclusion will fail.
if I am right, then may be I understand this part otherwise i might need help
Good luck to all of you. I don't have that much preparation, I want to get experience , what it is or how i feel in the exam hall.....
I will sit for February or April .
