Even though recent national statistics suggest a

in phrase "for doing", doing refers to a general action not belonging to any specific noun in the sentence
compare
I learn gmat to take MBA.
this means I learn gmat so that I take an MBA. this is logic.

I learn gmat for taking an MBA

taking dose not refer to "I" , taking refers to general action of anybody.
so, I can understand that

I learn gmat so that anybody take an MBA. this is not logic.

gmat test to do/doing a lot. and this is a hard point.

The whole sentence is in “simple present” tense. So, the use of “present continuous - stimulating” is wrong here. Hence, A, C and D are out. E could be eliminated for unnecessary use of passive voice in the sentence. Hence, B is the answer.

A.the Federal Reserve Board needs to lower short-term interest rates further for stimulating
Use of "for" + gerund is incorrect replacement for infinitive of purpose (reason for verb).

B.the Federal Reserve Board needs to lower short-term interest rates further in order to stimulate
Correct.

C.the need is for the Federal Reserve Board to lower short-term interest rates further for stimulating
Unclear what need it is referring to.

D.there need to be a further lowering by the Federal Reserve Board of short-term interest rates for the purpose of stimulating
S-V agreement. "There need" should be "There needs" since "There" refers to gerund "lowering."

E.short-term interest rates need to be lowered further by the Federal Reserve Board so as to stimulate
Passive voice not preferred. I feel like "So as to" is not correct here, but I'm not sure why.

Hi, Can anyone explain what is the problem in "E" , apart from the fact that it is Passive voice. I chose E because it says "lowered further", the adverb here is near the verb. So it makes more sense ?
