According to the American psychologist Howard Gardner the concept of

OFFICIAL EXPLANATION



THE PROMPT AND OPTIONS







[So -- are linguistic and logical ability more important than these other kinds of intelligence? Is there a difference between a "section" and a "sub-category"?
We have a meaning issue. Are linguistic and logical "sections" theoretically more legitimate or "real" than sub-categories are, if there is any difference between a section and a sub-category? ]


[Now we have a problem about 180° from that in option C: are the linguistic and logical sections of intelligence going to be subsumed into other sub-categories?
I don't know the relative importance of "section" and "sub-category." And I am working too hard to figure out what this guy is trying to say.]


• A sociologist is not satisfied with the way intelligence is defined because many other kinds of intelligence are demonstrated constantly but not recognized.
Intelligence is constituted not only by linguistic and logical aptitude but also by other abilities.
The grammatical sentence that conveys the current model's shortcoming is the winner.
I read "other sub-categories" as "in addition to the subcategories of intelligence that we call 'logical' and "linguistic'."

• HIGHLIGHTS

So . . . first we make you learn the idioms and then . . .
we goof around with them.

The idiom at issue is Not only X but also Y

• DETAILS

IDIOM? NOT X BUT ALSO Y
-- Sometimes we use what looks like that idiom—the but also part—without "not only."
-- In that case, usually we have: [CLAUSE 1] + comma + BUT ALSO [CLAUSE 2]
Correct but very rare on the GMAT:
Correct:The teacher gave us a lot of homework, but she also promised us a party if we did well.
-- in this situation, the word but is just a conjunction that joins two clauses.

-- Sometimes we have "not only" without "but also."
EducationAisle pointed out the one official example that I recall, here. Not only is followed only by "also."

Occasionally, idioms don't make sense. You just remember them.
Not X but Y, though, has an internal logic that we can figure out if we just think about what the words mean.
The "correlative conjunction" suggest that both X and Y will happen, are good, etc. — but the Y element is a bit or a surprise or something extra whereas the X element is expected.

In this sentence, an expert is arguing against the tide of opinion.
He wants to refine and expand the concept of intelligence.
Intelligence should be categorized not only by logical and linguistic mastery, but also by other kinds of mastery.

PARALLELISM
If the idiom is in play as it is in option (B), the X and Y elements must be parallel.
Not only is the idiom marker and the beginning of the structure.
Words that apply to both X and Y must be placed once outside the structure or must be repeated twice inside the structure.
Correct, once outside: A dancer is || not only an artist but also an athlete.||
Correct, twice inside: A dancer || not only is an artist but also is an athlete.||

• Split #1: Subject/verb agreement

The singular verb IS in Option A does not match displays, plural.
Eliminate A

• Split #2 - incorrect idiom usage

Option B lacks parallelism.
X = be divided into linguistic and logical sections
Y = a number of other sub-categories
Once inside is wrong (once outside is correct): be divided not only into linguistic and logical sections but also

Option C conveys a strange meaning and lacks contrast.
The logic is slippery. See my notes above.

Option D suggests another strange or hard-to-parse meaning. See my notes above.

If I cannot decide whether to eliminate an option in 2 seconds, I keep it tentatively.
Compare C and D to option E.
No contest. Option E is superior because it is clearer than (C) and (D).
Option (E) is not entirely clear. But it is better than the other options.

Eliminate B, C, and D

By POE, the answer is E
• the correct verb, are, is used.
• the option is parallel
be divided || not only into linguistic and logical sections but also into a number of other sub-categories as there are
• the option is logical and the most clear of B, C, and D.

DinoPen , welcome to SC Butler. Glad to have you!

I'm going to keep this short because it's late where I am.
I gave kudos to say thank you to Education Aisle for being helpful.
