Tests conducted by National Automobile Association of India, have revealed that, on average, the vacuum brakes fixed on Nano mini cars perform better than other brakes fixed in any other comparable cars. Thus, any consumer who is purchasing a mini-car based solely on the criteria of safety should purchase a Nano. Which one of the following statements, if true, most weakens the argument?

A. Mini-cars are less safe than some other types of automobiles.
B. Most consumers purchase cars based on multiple criteria in addition to safety.
C. During the test, the brakes on some Santro mini cars outperformed those on some Nano cars
D. The brakes on Nano mini cars are simple to use and maintain.
E. The Santro mini-cars achieved a better frontal-collision safety rating than the Nano mini-cars.

Tests conducted by National Automobile Association of India, have revealed that, on average, the vacuum brakes fixed on Nano mini cars perform better than other brakes fixed in any other comparable cars. Thus, any consumer who is purchasing a mini-car based solely on the criteria of safety should purchase a Nano. Which one of the following statements, if true, most weakens the argument?

A. Mini-cars are less safe than some other types of automobiles.
B. Most consumers purchase cars based on multiple criteria in addition to safety.
C. During the test, the brakes on some Santro mini cars outperformed those on some Nano cars
D. The brakes on Nano mini cars are simple to use and maintain.
E. The Santro mini-cars achieved a better frontal-collision safety rating than the Nano mini-cars.

A. Comparison is only between Nano and Santro B. Factors other than safety are outside the scope. C. Brakes on some mini cars are not fully in line with the focus of the topic. D. Simplicity and ease of operation are not in consideration here. E. Significantly weakens the argument; The passage claims that people should buy Nano if they consider only the safety aspects. The premise is that the brakes of Nano is superior to those of other cars in the same category. Nonetheless there could be a different aspect related to safety that makes Nano inferior to some other car. This option highlights such an aspect and therefore weakens the argument.

I think this is a poor-quality question and I don't agree with the explanation. Totally upset with the quality of the Q. Stimulus talks about 'Nino' cars whereas the options refer to 'Nano'.
Choice C is rejected because brakes on some cars are not 'in line' with the argument. The main premise mentions braking system only of Nino cars.
E is the OA because supposedly 'crash test rating is mandatory for a safe car' - isn't it a common knowledge from outside world? Does one need to know about crash test rating in order to write GMAT?
I think C is anytime better than E.
Thanks,

Thank you for reporting the typo. I have fixed it. But I think it's a good question. Notice the placement of the word "some" in option C. Some can mean anything from 1 to many, so it could be an exception - and hence not the best weakener out of 5 options.

I think this is a poor-quality question and the explanation isn't clear enough, please elaborate. Is it correct to have a comma between "of India" and "have revealed"?
The use of "fixed" is confusing. I'm reading it as meaning "repaired" but it can also be read as "placed."
The second sentence is missing a period after "Nano."
The question should be below the passage, not part of it.

I think it's a poor quality question. One is not supposed to know what is "frontal crash-test", and how it's related to the safety issues.
There is no correct answer here. One that would work - should be around "breaks performance isn't related to the safety".

Although one may not have prior knowledge about frontal crash-test, it can be deduced from the name itself. Nonetheless to clear the ambiguity, we have changed the the wording of option E.

Your suggestion "brakes' performance isn't related to the safety" could be a feasible answer but practically not applicable. The passage claims that people should buy Nano if they consider only the safety aspects. The premise is that the brakes of Nano is superior to those of other cars in the same category. Nonetheless there could be a different aspect related to safety that makes Nano inferior to some other car. Option E highlights such an aspect and therefore weakens the argument.

Nano cars are a subset of Mini cars, opt A tells us that "Mini-cars are less safe than some other types of automobiles", this will clearly shake the conclusion of the argument.
The lesser safe characteristic of mini cars will be obvious to apply on nano cars as well.

A could be a weakener, but E weakens the argument much more convincingly.

The conclusion is that among the mini cars, Nano is the safest. Option A does not state that Nano is less safe than other mini-cars - the option just states that Nano is less safe than some other cars (may or may not be mini-cars). On the other hand option E directly states that there exists another mini-car that is safer than Nano in some aspect. Since the comparison in option E is between mini-cars, whereas the comparison in option A is between Nano and some unknown cars, option E weakens the argument more than A does. The question asks which option most weakens the argument, and hence E is better than A.

Please let me know if you still have doubt.

These CR explanations are very poor.

How should we reasonably know that comparisons are only between Santro and Nano? For example w/ answer choice A, Santro is not stated in the stem. Instead information is brought from other answer choices to provide reason as to why the answer choice is incorrect. Also, how should we understand reasoning for both the incorrect and correct answers with only one sentence? Makes no sense.
