gmat paper prep SC #11 (52)

by lalabee » Mon Feb 11, 2008 9:36 pm
Hello,

im only sure the answer is not C&D, but i'm not sure why A or B cannot be the answer ..

(is "rates for" the right idiom, that's why the answer choices should narrow down to D&E, and then E should be the correct answer?)

OA is E.

Sturat, could you kindly help.


Thanks.

"rates for" is the correct idiom.

"Rate of" and "rate for" have two different meanings - each could be correct.

For example:

My rate of travel to work today was 30 kph.

My rate for fixing dishwashers is $50 an hour.

(a), (b) and (c) all have comparison issues - they compare "the rates.. of depression" to "the population at large". We can compare rates to rates or populations to populations, we can't mix and match. If (b) had ended with "than are THOSE in"... it would have been great.

In fact, all the choices really come down to the comparison.

(e) has "more prevalent than in", which makes sense with the rest of the sentence.

(d) has "as prevalent when compared to" - if we have one "as", we always need a second "as"

idiom

There cannot be a rate of depression. Rates are countable and depression is not countable. therefore eliminate abc. D has the idiom issue and e holds a nice idiom of "more x than Y"..

ABC all have idiom issues once you see them as incorrect you should be able to pick apart that e is better than d. IF you want me to explain any further friend please let me know.. keep you head up we are almost there to pass 700.

E is correct and the reason is:

in A,B and C if you get rid of the middle man it reads "the rates are more prevalent". how can rates be more prevalent. It should read depression is more prevalent.

So A,B and C are out.

Between D and E, E stands because "more prevalent than in" is more idiomatic.
