hey cooldude, ( i just dont want to address you by that name... )
you ask too many questions (i dont have any problem as long as you get the replies...haa haa)

although Prachi's doing great work here, here's my personal advice:
dont just look out for correct answer and then correct explanation.
i believe 1000SC OA are correct; so try to think why they are correct.... by doing so you will make a good habit of thinking in the way it should be thought...
..err i mean you will develop the correct process of approaching problem

as far as concede is concern both can go ...depends on the sentence...

eg.......conceded the fact ...
or ......conceded that the difference between.....

(B) that nothing other than a technical or scientific breakthrough is needed
(C) that a technical or scientific breakthrough is necessary
(D) the necessity for an occurrence of a technical or scientific breakthrough
(E) the necessity for a technical or scientific breakthrough occurring

but for this case that is correct the word occurance is unnecessary!
& A & B are way out of consideration they just dont make a good senetence.

PS:
Hey Eric, you can do this much more organised.
you can make a special forum for 1000 SC series...it seems that every question of that pakage is going to launch here as a query someday...its just a matter of time...

so giving sp forum for it would be much organised ..
what do you think...
same case applies to 800guys problem seires!
do think about that!

Supriya:

Thanks for your suggestion about the forum areas--I'll think about it. I all ready hold the opinion that there are too many forum areas on this website at the moment, so I'm hesitant to add more areas. But who knows, that might be the right solution...

[smilingsupriya]

Occurrence sorry my spelling mistake. 800guy is a person on btg who has more than 100 difficult math problems :...

[ashish1354]

can some one suggest what is wrong with A)

[perlejj]

can some one suggest what is wrong with A)

In A, the word breakthrough doesn't need 'no less than' cuz the word itself is enough. It's redundant.

Thanx! Perlejj, for the explanation that you gave given. I was stuck at option A.
Thanx once again
