What is wrong with D.
I rejected E as it stated "neuron growth in canaries that sing", which seems to alter the meaning.


souvik101990 please suggest.



Hello ankursethi297,

I would be glad to help you with this query. :)

Let's take a look at Choice D: the brain growth in mice when placed in a stimulating environment or the increase in canaries' neurons when they

The pronoun they in this choice grammatically refers to neurons, suggesting that the neurons learn new songs. Logically, they must refer to canaries'. But because canaries' appears in this choice in possessive form, the non-possessive pronoun they cannot refer to the possessive noun canaries' because possessive nouns act as an adjective.

Also, this choice seems to suggest that the brain growth in mice is placed in a stimulating environment. This meaning is certainly illogical.


Hope this helps. :-)
Thanks.
Shraddha

A. the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that
B. mice whose brains grow when they are placed in a stimulating environment or canaries whose neurons increase when they
C. mice's brains that grow when they are placed in a stimulating environment or canaries' neurons that increase when they
D. the brain growth in mice when placed in a stimulating environment or the increase in canaries' neurons when they
E. brain growth in mice that are placed in a stimulating environment or an increase in neurons in canaries that

Why not b?


A. the brain growing in mice when placed in a stimulating environment or neurons increasing in canaries that
Incorrect

B. mice whose brains grow when they are placed in a stimulating environment or canaries whose neurons increase when they
Mice or brains? Could be clearer so we'll put "maybe" if there's no better answer.

C. mice's brains that grow when they are placed in a stimulating environment or canaries' neurons that increase when they
Neurons don't learn new songs

D. the brain growth in mice when placed in a stimulating environment or the increase in canaries' neurons when they
Same as C

E. brain growth in mice that are placed in a stimulating environment or an increase in neurons in canaries that
Best answer

dear GMAT Ninja
I got this wrong. But, after that I find the use of WHEN is incorrect in all the first four options. Will it be deterministic error or can we really eliminate all 4 on the basis of wrong use of WHEN.

No, a wrong answer cannot be eliminated because of use of "when".

Option D is eliminated not because "when" is used, but because parallelism is lost.

In option D, "when placed in a stimulating environment" comprises of a participle ("placed"), whereas "when they learn new songs" comprises of a clause. D would be better if the last part were as follows: "when learning new songs" (participle instead of clause.)

Moreover "increase in Neurons IN CANARIES" in E (rather than "increase in canaries' neurons)" in D goes better with "brain growth IN MICE"

Another problem with D is that the subject pronoun "they" refers to the possessive antecedent "canaries' "

I had a theory in mind when I was solving this question.
Complex gerunds can be parallel with action nouns only, and not with simple gerunds or concrete nouns. Examples of production of brain cells qualifies as action noun, and therefore can be parallel with a complex gerund or action noun only.
Does the answer satisfy the above theory?

The new cells seen in the rat brains appear at a higher rate after challenges like intense training, injury or an infection, Dr. Raastad said. Within a few years, researchers found the cells in adult mice, guinea pigs, rabbits and monkeys. In the mid-1980's, other researchers found irrefutable evidence that new cells were born in the brains of adult canaries learning new songs and chickadees that were remembering where they had stashed their winter seeds. But researchers still did not believe that new cells were created in human brains, Dr. Raastad said.

In 1997, Dr. Elizabeth Gould, an assistant professor of neuroscience at Princeton, and colleagues showed that neurogenesis, or the birth of new cells, occurred in the hippocampuses of tree shrews and marmoset monkeys. But Dr. Rakic and others said this was not possible in humans.

In 1998, Dr. Gage demonstrated that the number of brain cells in the hippocampuses of mice raised in stimulating environments increased by 15 percent -- and that the cells were born in the ventricle zone.


A- include the brain growing is incorrect
B- when they are-they is ambiguous- mice and brains
c- again they is ambiguous
D- when placed is incorrect- it can refer to brain or mice
E-Correct
