Question

The Z-300 is a particularly fast new sports car, popular among young drivers. It is an expensive model, and relatively few are on the roads. Two months ago, seven different young people in Catoville were arrested for operating the Z-300 at excessive speeds on local roads while having a blood alcohol level well above the legal limit. Since then, a police watch group has reported that Catoville traffic cops frequently have been pulling over drivers of the Z-300 and testing them for alcohol: the total number of Z-300 drivers stopped and tested is five times greater than the total number of drivers of all other makes or models stopped and tested.

Which of following conclusions can most properly be drawn from the information above?

(A) Drivers of the Z-300 exceed local speed limits by much higher margins than that by which they exceed highway speed limits.

(B) Some drivers of the Z-300 are unfairly subjected to delays.

(C) The Catoville traffic cops have provided an effective deterrent to drunk driving within Catoville.

(D) Drivers of fast sports cars are more likely to drive under the influence of alcohol than drivers of any other make or model of car.

(E) In the past month, the rate of arrests for drunk driving are much higher for drivers of the Z-300 than it is for drivers of any other make or model of car.

(A) Drivers of the Z-300 exceed local speed limits by much higher margins than that by which they exceed highway speed limits.
No information about margins, though we know Z-300 has capability to achieve high speeds.

(B) Some drivers of the Z-300 are unfairly subjected to delays.
Their is disproportionate checks for drivers of Z-300; However, we do not know whether they were actually violating the rules. In the event of not found guilty. some of the drivers must have been unfairly subjected to delays because of such checks. Keep

(C) The Catoville traffic cops have provided an effective deterrent to drunk driving within Catoville.
No information on the result

(D) Drivers of fast sports cars are more likely to drive under the influence of alcohol than drivers of any other make or model of car.
No information about how likely drivers of sports car are compared with ordinary cars

(E) In the past month, the rate of arrests for drunk driving are much higher for drivers of the Z-300 than it is for drivers of any other make or model of car.
No information about arrests; However, we know the rate of checks are much higher for sports cars. if most of them are driving under the influence of alcohol. This option is likely to be correct.

I am not able to pick any option with certainty, but I mark B.

OFFICIAL EXPLANATION

We know the Z-300 sports car is fast, expensive, and rare. Two months ago, seven Z-300 drivers were arrested for DWI. This month, the police are stopping Z-300s and testing drivers for alcohol with tremendous frequency. Even though the Z-300s are rare, the number pulled over is "five times greater" than the number of all other makes & models pulled over. It seems that virtually every Z-300 is going to be pulled over. Even though there was an association two months ago between the Z-300 and DWI, it would be completely illogical to conclude that every single Z-300 driver without exception is DWI. Therefore, some Z-300 drivers are being pulled over and tested, perhaps multiple times, even though they are not DWI.

(B) is the credited answer. Since some Z-300 drivers must be innocent of DWI, they are subject to unfair delays when they are pulled over.

(A) is irrelevant: it makes the distinction highways vs. local roads, which does not play any role in the argument.

(C) is not true: it seems the cops are disproportionately focusing on drivers of the Z-300, which is a relatively rare car, and thus all other cars in Catoville are checks less frequently, which would make it easier for drunk drivers of other cars to escape notice.

(D) is the cops' operating assumption, but there is no logical support for this. Two months ago, there was a strong association in Catoville between one kind of sports car and DWI, but there is nothing else to suggest that this is a longterm or widespread pattern.

(E) is uncertain: we know that Z-300s have been pulled over at a very high rate, but we have no evidence that the drivers were cited and arrested in large numbers. If anything, one might suspect that Z-300 drivers, feeling the heat, would desist from drunk driving until this period of police scrutiny passes.

B looks ok wrt rest of the choices. Waiting for OA and a discussion on this question.

How are we assuming here that some are innocent for sure here?

The Z-300 is a particularly fast new sports car, popular among young drivers. It is an expensive model, and relatively few are on the roads.

Which of following conclusions can most properly be drawn from the information above?

We know there are relatively few Z-300s, yet police are stopping and testing Z-300 drivers far more than all other drivers combined. That implies Z-300 drivers are being targeted for stops and tests, which will inevitably inconvenience at least some drivers who have done nothing wrong.

(A) Drivers of the Z-300 exceed local speed limits by much higher margins than highway speed limits.

No info about highways or comparing margins.

(B) Some drivers of the Z-300 are unfairly subjected to delays.

Yes. Given the heavy focus on stopping/testing Z-300 drivers, and the fact that not all of them will be drunk, some will be delayed despite not doing anything to justify an alcohol test.  This is the only conclusion that follows from the policing pattern.

(C) The cops have provided an effective deterrent to drunk driving.

No evidence about changes in drunk driving rates.

(D) Drivers of fast sports cars are more likely to drive drunk than all others.

The evidence is about policing and 7 arrests, not comparative likelihood across all sports cars.

(E) In the past month, the arrest rate for Z-300 drivers is much higher.

No arrest data for the past month, and no rate comparison.

Answer: (B)

Hi  Adit_  let me try to help with this.

So as per the argument, we have been given the info about Z-300
1. Fast new sports cars
2. Expensive and a few on roads, lets say 10 cars
3. 7 out of 10 were arrested for high speed and drunk driving- 2months ago, let's say in Jan,2026
4. Since jan 2026, traffic police have is pulling over the Z-300 for alcohol testing
5. Total no. of drivers who have been stopped and tested frequently > 5 times greater than other make and models.

As we took 10 cars, it might be the case they all were stopped, maybe once or more than once, or some of them out of these were stopped for checking multiple times, which can sum up to 5 times higher than others; this can't be disputed because we have to take it as true. We know from argument 7 they were arrested, but those 3 were not right; they may or may not have been drunk and speeding. So based on this info, we are taking Option B as most properly inferred.

However, in my opinion, it is also not correct because it is talking in definite terms, but we don't have any clear info, so this option is clearly taken as the best among all.

PS—Don't get too attached to the unofficial questions; they may have been crafted just for practice. Yes, your question is legit, and I thought so too, but still, based on the question stem, this can be true but is definitely not a must-be-true.

Hope this helps

Adit_ · Answer

Thanks for your response!
I usually go for a consistent methodical approach whether I get an answer right or wrong. In this case when the question stem is about "must be true" I simply reject the options that is even remotely out of what is exactly stated in the passage. And I understand there is an explanation as to why it is the answer but I dont want to avoid going through the consistent approach I have been going through just for some slight anomalies like such questions. I would love to get more insights on this question however!

IMO the OA option should have been like this:
" Some drivers of the Z-300 may have been unfairly subjected to delays."

AbhishekP220108 · Answer

Adit_  I agree with your version of the answer, and as the question stem states, "can be most properly inferred," here we have to select the option that can possibly be true as per the given information. Since option B can be true, and it has all the key elements that we use in a methodical approach. Let's see if we can get any expert opinion over this.

Hi Experts requesting your input over this.

gchandana · Answer

Hi  Adit_

We can't assume for sure that some are innocent or that all were guilty, can we? It is just that B is more reasonable than the rest of the pack.
We are choosing an option that requires fewer assumptions than the others.

A couple of things:
1. In CR, one can't expect the correct answer to do 100% of the job it is supposed to. If the correct answer does the job just even slightly better than the rest 4, it still works. 
If we eliminate options like you said, that is even remotely out of what is exactly stated in the passage, all the options will be eliminated, which can't be the case, can it? So look towards comparing the options.

2. There are even official questions that have debatable OA, and this is an unofficial question, so it is advisable not to stress over just a few questions, just like you mentioned, as you don't want to modify your approach for just a few such questions.

P.S. In CR, you may want to have two different approaches or strategies for easy/medium and hard questions. Because hard questions can be very tricky, and the same strategy used for easy/medium ones may not work well for harder ones.

Hope this helps!
