GMAX Challenge Question

IMO C.

1. Considered as/to be - incorrect idiom. So, A and B are out.
2. In D, there is contrast but the sub-clause starts with the tool, which is not modifying the introductory contrast. So, D is out.
3. In E, meaning is awkward and chenge in tense is incorrect [that which had been]. That and Which cant be placed together in a clause.

The New Cognition computational tool is actually now the world’s fastest in terms of potential maximum performance, but that is considered to be a less relevant measure than the actual computing rate obtained on a standardized test.

A. The New Cognition computational tool is actually now the world’s fastest in terms of potential maximum performance, but that is considered to be a less relevant measure than the actual computing rate obtained on a standardized test.
the correct idiom is "considered"
B. Actually, the New Cognition computational tool is now the world's fastest tool in terms of potential maximum performance, but that is considered as a less relevant measure compared to the actual computing rate obtained on a standardized test. the same reason

C. The New Cognition computational tool is actually now the world’s fastest in terms of potential maximum performance, but this theoretical rate is considered a less relevant measure than the actual computing rate achieved on a standardized computing test.

D. Although considered a less relevant measure than the actual computing speed achieved on a standardized computing test, the New Cognition computational tool is actually now the world’s fastest in terms of potential maximum performance.

E. In terms of potential maximum performance, the New Cognition computational tool is now the world's fastest, but this theoretical rate is considered a less relevant measure than that which had been achieved on a standardized computing test.[/quote] no need for past perfect
BTW C and D. I found D to be unclear. And here the modifieк is too complex.
On the other hans, C is more concise and clear.

C

In C what is the antecedent of this? Pls clarify

Thanks

The New Cognition computational tool is actually now the world’s fastest in terms of potential maximum performance, but that is considered to be a less relevant measure than the actual computing rate obtained on a standardized test.

A. The New Cognition computational tool is actually now the world’s fastest in terms of potential maximum performance, but that is considered to be a less relevant measure than the actual computing rate obtained on a standardized test.
demonstrative pronoun must be attached to a noun, however that can be used as a noun provided that is is modified.

B. Actually, the New Cognition computational tool is now the world's fastest tool in terms of potential maximum performance, but that is considered as a less relevant measure compared to the actual computing rate obtained on a standardized test.
demonstrative pronoun must be attached to a noun, however that can be used as a noun provided that is is modified.

C. The New Cognition computational tool is actually now the world’s fastest in terms of potential maximum performance, but this theoretical rate is considered a less relevant measure than the actual computing rate achieved on a standardized computing test.
Correct


D. Although considered a less relevant measure than the actual computing speed achieved on a standardized computing test, the New Cognition computational tool is actually now the world’s fastest in terms of potential maximum performance.
Sentence begins with a fragment

E. In terms of potential maximum performance, the New Cognition computational tool is now the world's fastest, but this theoretical rate is considered a less relevant measure than that which had been achieved on a standardized computing test.
"In terms" nonsensically modifies " the ... tool"

IMO:

"This" is a demonstrative pronoun acting as a adjective, which modifies "theoretical rate".

I beg to disagree, this cannot be adjective. "this" is only a pronoun which has to replace some noun or be a place holder (like expletive it)

According to MGMAT Demonstrative pronouns (This, That, These, Those) act as adjectives and need to be attached to a noun.

Ex: I like these shoes.

An exception is "That and Those" can act as a noun if they are acting as a copy of another noun--in this scenario the demonstrative pronoun must be modified to indicate how it is different from the original copy.

Ex: I love my shoes, but I hate those of my neighbor.

And the answer is....
A. First, "that" in the clause "that is considered…" has no referent. Second, "less relevant… compared to" is unidiomatic; the comparative structure should be completed by the word, "than".

B. "Actually" is not modifying any word here. Second, "considered as" is unidiomatic because "considered" has no verbal connection when used correctly in the SC on the GMAT. Third, the comparison is still unidiomatic because "less… compared to" violates the comparative structure "less… than."

C. Correct: The comparison is logical, comparing theoretical speed to actual speed. It also uses idiomatic structure for the comparative, "less… than." Finally, there is no need to use the word "tool" twice, and thus this answer is more concise.

D. The sentence begins with the subject modifier (description of the subject), "considered a measure," but the subject is the tool, which cannot logically be considered a measure. Thus, the subject modifier is illogical.

E. "In terms of…" should modify the word "fastest" because the intended meaning of the sentence is that a particular aspect of the tool is fast, namely, it's potential performance, not that the tool is fast. Second, "that which" is considered unidiomatic on the GMAT SC. Finally, there is no justification for use of the past perfect, as there is no indication that a past action had taken place before a point in time in the past.

thanks Sarai!!!
