The reserve bank of India examines macro-economic

I don't think this question is bullshit - in fact the both choices B and D are grammatically correct, IMO. However, choice B is wordy (compare - "it uses the guidelines..." with "using the guidelines..."); in effect choice B uses two independent clauses joined with a comma and conjunction "and" whereas choice D uses only one independent clause - Generically choice D can be paraphrased as - "The RBI examines X and, using Y decides Z" and choice B can be paraphrased thus: "RBI examines X and IT uses Y in deciding Z". Clearly D is more succinct.

D for me

The reserve bank of India examines macro-economic environment and external conditions, and in using the guidelines it derives from these analyses, can decide the fiscal and monetary policy.

A. conditions, and in using the guidelines it derives from these analyses, can decide
And should precede comma.
B. conditions, and it uses the guidelines derived from these analyses in deciding
This sentence could make sense without comma and without it, which destroys parallelism
C. conditions and, in using the guidelines derived from these analyses, deciding
Incorrect use of participle here.
D. conditions and, using the guidelines derived from these analyses, decides
This participal phrase describes on what base the bank provides its decisions - how it decides - and is properly separated with 2 commas.
E. conditions and, in its use of the guidelines it derives from these analyses, it decides
Wordy + it is redundant

I agree with the explanations given by "cracky"
Further, "examines" and "decides" seem more parallel than
"examines and, it uses" as employed in option B
If B had been "RBI examines..., and it uses ...to decide (to infinitive)..."
i would have chosen that option.

A. conditions, and in using the guidelines it derives from these analyses, can decide --> modifier "in using the guidelines it derives from these analyses" is awkward and is not placed near the noun (reserve bank) it is supposed to modify.

B. conditions, and it uses the guidelines derived from these analyses in deciding --> it correctly refers to "the reserve bank" and clause both before and after paraller marker "and"
are parallel. Correct

C. conditions and, in using the guidelines derived from these analyses, deciding --> modifier "in using the guidelines derived from these analyses" is awkward and is not placed near the noun (reserve bank) it is supposed to modify. Also deciding is not parallel.
D. conditions and, using the guidelines derived from these analyses, decides --> modifier "using the guidelines derived from these analyses" is correct but not placed near the noun (reserve bank) it is supposed to modify.
E. conditions and, in its use of the guidelines it derives from these analyses, it decides --> --> modifier "in its use of the guidelines it derives from these analyses" is awkward.

Hey All,

I got asked by PM to take this one on. So...

The reserve bank of India examines macro-economic environment and external conditions, and in using the guidelines it derives from these analyses, can decide the fiscal and monetary policy.

A. conditions, and in using the guidelines it derives from these analyses, can decide
PROBLEM: This modifier "in using" is confusingly placed here after the "and". There's no way to know what it's modifying. (Prepositional phrases are always modifiers)

B. conditions, and it uses the guidelines derived from these analyses in deciding
PROBLEM: No reason to have the "it" here, as the subject hasn't changed.

C. conditions and, in using the guidelines derived from these analyses, deciding
PROBLEM: Failed parallelism between "examines" and "deciding".

D. conditions and, using the guidelines derived from these analyses, decides
CORRECT: Parallelism between "examines" and "decides" is great. The participial modifier is a bit oddly placed, but it's legal.

E. conditions and, in its use of the guidelines it derives from these analyses, it decides
PROBLEM: No reason to add all these "its" everywhere. The middle modifier is illogical.

Hope that helps!

thanks Tommy! I picked B, but your explanation was good.

The bank examines....., and in using.....can decide....

in using does not make sense after and.

Also can decide should be changed as well...either decides or some other form.

So answer has to be B or D. In D only thing I can notice is...decides should have been it decides to make it better...but still that seems to be acceptable to me. I will still go with D.

Please explain what is wrong with option B.
In option D, after this phrase "using..." RBI should come. This phrase alone is not modifying "RBI". Experts, please explain.
daagh sir, GMATNinja sir. Please help.

using the guidelines derived from these analyses......I think this sentence is not modifying the reserve bank properly....eventhough we have parallelism between examines and decides this sentence should properly modify the reserve bank

Hello brt,

We hope this finds you well.

To answer your query, "using the guidelines derived from these analyses" is an adverbial modifier, so technically it modifies the verb "decides", and in doing so modifies the noun that takes the action of "decides" - the bank.

We hope this helps.
All the best!

Hello, egmat

Logically what is the difference between B & D?
What part of sentence is to made parallel is decided by marker so here what part should be made parallel?
