check out this one homies:

Any serious policy discussion about acceptable levels of risk in connection with explosions is not well served if the participants fail to use the word "explosion" and use the phrase "energetic disassembly" instead. In fact, the word "explosion" elicits desirable reactions, such as a heightened level of attention, whereas the substitute phrase does not. Therefore, of the two terms, "explosion" is the one that should be used throughout discussions of this sort.

Which of the following is an assumption on which the argument above depends?

A In the kind of discussion at issue, the advantages of desirable reactions to the term "explosion" outweigh the drawbacks, if any, arising from undesirable reactions to that term.
B The phrase "energetic disassembly" has not so far been used as a substitute for the word "explosion" in the kind of discussion at issue.
C In any serious policy discussion, what is said by the participants is more important than how it is put into words.
D The only reason that people would have for using "energetic disassembly" in place of "explosion" is to render impossible any serious policy discussion concerning explosions.
E The phrase "energetic disassembly" is not necessarily out of place in describing a controlled rather than an accidental explosion.

I think it's A.


B The phrase "energetic disassembly" has not so far been used as a substitute for the word "explosion" in the kind of discussion at issue.
This hasn't been stated

C In any serious policy discussion, what is said by the participants is more important than how it is put into words.
This goes against the argument

D The only reason that people would have for using "energetic disassembly" in place of "explosion" is to render impossible any serious policy discussion concerning explosions.
There's no assumption made about why people would use "energetic disassmbly" - we could envisage that it's because they like big words, because they believe it's more precise etc. But no assumption can be supported from the text.

E The phrase "energetic disassembly" is not necessarily out of place in describing a controlled rather than an accidental explosion.
This may be true, but it is not relevant to the argument.

By POE, it has to be A.

A for me to!

What is the source of such questions ?
Personally i see them as 800 + questions (impossible) .
I did CR from OGs 10, 13 with 90% accuract but never encountered questions wit so close options.
Here i almost reached A n D n then selected D
Former GMAT takers, did u encounter such questions in real exam ?
