Proper parallel construction is in Choices B and E

E uses Having been which is an +ing modifier it should modify the subject of the clause... It illogically says neuclear testing is doing the job of signing

hence left with B-My choice

hfbamafan · Answer

I am going with B

A) which was signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and is providing guidelines for proper handling of radioactive material to protect the environment. Improper parallelism
B) which was signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and provides guidelines for proper handling of radioactive material to protect the environment. Correct
C) which, had being signed in 1996 by 71 states, prohibits all nuclear explosions, disallows scientific research, and guidelines for proper handling of radioactive material to protect the environment. Had being is improper tense construction
D) which was signed in 1996 by 71 states prohibiting all nuclear explosions, and disallowing scientific research and the radioactive material’s proper handling guidelines to protect the environment. just sounds redundant
E) having been signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and provides guidelines for proper handling of radioactive material to protect the environment. the second and makes it sound like the treaty was signed and prohibition of nuclear explosions occurred at the same time.

IMO Straight forward B

A) which was signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and is providing guidelines for proper handling of radioactive material to protect the environment.  Improper parallelism 
B) which was signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and provides guidelines for proper handling of radioactive material to protect the environment.  My Choice,  
C) which, had being signed in 1996 by 71 states, prohibits all nuclear explosions, disallows scientific research, and guidelines for proper handling of radioactive material to protect the environment.  and guidelines is not proper and parallel, we do not know whether they are guide lines or the guidelines are being laid 
D) which was signed in 1996 by 71 states prohibiting all nuclear explosions, and disallowing scientific research and the radioactive material’s proper handling guidelines to protect the environment.  awkward and wordy 
E) having been signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and provides guidelines for proper handling of radioactive material to protect the environment.  having been signed and prohibits are not parallel

Here is the OE,

Nuclear testing on the planet is regulated by the Comprehensive Nuclear-Test-Ban-Treaty,  which was signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and is providing guidelines for proper handling of radioactive material to protect the environment.

(A) which was signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and is providing guidelines for proper handling of radioactive material to protect the environment.

The phrase “is providing guidelines ….” is not parallel in structure to “was signed in 1996 by 71 states,” “prohibits all nuclear explosions” and “supports scientific research.” All the list elements should have parallel structures.

(B) which was signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and provides guidelines for proper handling of radioactive material to protect the environment.

CORRECT. The phrase “provides guidelines ….” is parallel in structure with “was signed in 1996 by 71 states,” “prohibits all nuclear explosions” and “supports scientific research.” All the list elements are parallel and the sentence does not contain any other verb/tense error.
 
(C) which, had being signed in 1996 by 71 states, prohibits all nuclear explosions, disallows scientific research, and guidelines for proper handling of radioactive material to protect the environment.

The verb construction “had being signed” is awkwardly constructed and grammatically incorrect.

(D) which was signed in 1996 by 71 states prohibiting all nuclear explosions, and disallowing scientific research and the radioactive material’s proper handling guidelines to protect the environment.

Using the verb-ing form “prohibiting” just after the “states” incorrectly implies that the states are prohibiting “all nuclear explosions”; the treaty is the one which is doing the “prohibiting”.

(E) having been signed in 1996 by 71 states and prohibits all nuclear explosions, disallows scientific research, and provides guidelines for proper handling of radioactive material to protect the environment.

First, the modifier introduced by the word “having” is grammatically incorrect; verb phrases must be preceded by a relative pronoun such as "which." Moreover, the modifier “having been signed in 1996 …” is not parallel with verb phrases “prohibits …, disallows …, and provides….”

Vercules,

Below is your explanation for the question in the link given rather-than-accept-the-throne-of-kapilavastu-lord-buddha-152255.html

(D) Rather than accept the throne of Kapilavastu, Lord Buddha went towards the path of complete awareness to see whether he could achieve a state of enlightenment, having been sent by his inner instincts.

CORRECT. This choice uses the construction “X rather than Y” to correctly compare the parallel active verbs “accept” and “went.” The uncertainty about reaching India by travelling west is correctly indicated by the word “whether.”

However, in this question you stated that passive (was signed) is parallel with active verbs (prohibits) Could you please elaborate?

Thanks,

Vercules · Answer

Hi hfiratozturk,

Good question, for parallel structures the verb tenses need not be in the same order.

Consider this sentence --  Obama  was born  in the USA and  serves  as the 44th president of the country.

Question no. 42 OG12 is a very good example of this.

Hope this helps,

Vercules

Bluelagoon · Answer

which is always used to refer to the subject before it. This is a question of parallelism. The treaty does 3 things X,Y , and Z. X,Y and Z have to have the same form. Here X=prohibits;Y=disallows. Both X and Y are action verbs. Hence Z should also be the same. Eliminate A,C and D. Between B and E, B is not a coherent thought. Treaty having been signed n 1996 by 71 states and -> This is incorrect. Now i don't know if having been is correct or not , but i will eliminate this on incorrect thought alone.

Hi Vercules,

In above sentence active verb can be parallel to passive verb  was signed in 1996 by 71 states and prohibits all nuclear explosions  is correct
but in your explanation for below ques, parallelism between active and passive verb is considered incorrect.
Could you please clarify:

Rather than accept the throne of Kapilavastu, Lord Buddha was sent by his inner instincts to see if he could achieve a state of enlightenment by going towards the path of complete awareness.

The construction "X rather than Y" requires parallelism between X and Y, but the original sentence pairs an active verb ("accept") with a passive one ("was sent"). Second, the use of "if" in this context is incorrect. "if" is used only to introduce conditional clauses (e.g. “if X, then Y”). Here, "whether" should be used instead of “if” to indicate uncertainty about achieving a state of enlightenment. GMAT prefers “if” to be used as a conditional and “weather” to express uncertainty about certain event.
