I will go with 5.

The examples can not be mice or mice's brain.

It needs to be the growth

From my point of view 1,2,3, and 4 do not make it clear what was placed in stimulating environment, is it the bain or the mice..

I will go with (4)

the sentence '...an increase in neurons in canaries that ..." in (5) doesnt sound good.

Almost everyone is going with 4. From my poin of view that is wrong. Here is how....

the brain growth in mice when placed (what is placed mice or brain growth) a stimulating environment or the increase in canaries' neurons when they (what does THEY refer to here. They is a pronoun that should refer to a noun, in this case the noun is canaries' neurons. Remember canaries' is in possessive form here).

5 resolves it all.

mice is a plural of mouse(singular).

brain growth in mice that are placed in a stimulating environment
or an increase in neurons in canaries that learn new songs.

I may be wrong because my brain is disfunctional these days....

I think the answer is <b>5</b>.

(1) "the brain" is not an example of neurogenesis

(2) "mice" is not an example of neurogenesis

(3) "mice's brains" are not examples of neurogenesis

(4) include should be followed by X and Y, not X or Y.

I think that's what's tripping me up. I agree with you; I'm looking for an X and Y structure with the word "include". But both (4) and (5) use X or Y.

I think I am wrong again here..
I will wait for the OA..

Guys, Please explain the answer & your approach to attack this SC

I feel B is correct.

C also is impressive". but, ""they are placed"" refers to the brain and not the mice.

Huh now i am kinda confused. Are mice placed in stimulating env. or their brains?? If their brains than as i have replied earlier C is correct for ||ism and pronoun they refering to correct noun.

C.

C for parallelism,

Mice are placed in stimulating environment. Mice brains can not be separated from mice and put into stimulating environment and that (brain) will grow!!!!!

in all the choices, it is brain (singular) not brains. so they clearly refer to mice (plural)

D

Clear in meaning. It uses nouns as "examples of neurogenesis" like "brain growth in mice " and "increase in canaries’ neurons".

It goes well with parallelism too.

OA is E!

Interesting that nobody got it right :? My answer was B when I first saw this SC.

This is what happens (according to me): it parallels examples of the production of new brain cells, i.e. nouns or noun phrases. However, the trick is the modifiers following these noun/noun phrases. The modifiers are either subordinate clauses or relative clauses. One should read the options with the modifying clauses in mind and correct accordingly.

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

- the modifying clauses are not parallel.

B. mice whose brains grow when they are placed in a stimulating environment or canaries whose neurons increase when they

- incorrect use of mice and canaries as examples (examples need to be of the production of new brain cells). Also, ambiguous use of they

C. mice’s brain that grow when they are placed in a stimulating environment or canaries’ neurons that increase when they

- incorrect use of mice's brain and canaries' neurons as examples. Also, ambiguous use of they in the second example

D. the brain growth in mice when placed in a stimulating environment or the increase in canaries’ neurons when they

- the examples are not parallel (canaries' neurons is in possessive form whereas the brain growth is not). Also, the modifying clauses are ambigious. E.g., they in the second example

E. brain grown in mice that are placed in a stimulating environment or increase in neurons in canaries that

- the examples and the modifying clauses are parallel.


Let me know if anyone is of a different opinion...

huh? E?

"..brain grown.." does not ever sound correct to me???

B seems to be the most parallel

B. mice whose brains grow when they are placed in a stimulating environment or canaries whose neurons increase when they

The option E is posted incorrectly in the question, it should be:

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


Can anyone explain why E is better and point out the mistakes in the other options...

though late 'E' seems ok to me..

it is because the orginal stem talks about neurogenesis, the production of new brain cells, the modifier clearly states that the subject being discussed here is a grown brain cell in mice and increased neurons in canaries..

C, B & A - talks about brain that would grow or canaries neruons that would increase . the process is yet to take place. and it cannot be documented.

D - talks about growth a process.. and not the results produced...

Will go with D. B/C have wrong modifiers.
A/E brain is not the example.
