hey Bannuel,
I think the solution is wrong. Statement 1 is flawed because mobile phones moving at a speed of more than 30 km/hr, does not only mean that it is necessarily in a car, on contrary, it can be a case where a person is traveling in a train or flight. So, this information will give misleading evidence re effect of mobile phone on driving.

on the other hand, statement 4 can be used to strengthen the fact that since other groups have also recommended to not use mobile phone then it would strengthen this citizen group argument to ban it

I like this point. Genius! I’m not sure if we are getting too granular but I like the little trap and I feel that the other problem with this answer or a genius Trap could be that the person is not the driver but a passenger in the car. This makes it a much harder question!

We just need to come up with a nice good other reason that would be solid and this could be our next wrong answer.

PS. This question was written by an American because there are no trains in the United States 😂 and the phone is supposed to be in flight mode while on the plane.

PPS. I have updated the answer choice and made A the incorrect one. Thank you!
I have added 2 weeks of GMAT Club tests to your account for this helpful suggestion.

Official Solution:


In State X, a citizens' group is advocating for a ban on mobile phone use while driving, citing concerns over accidents and damage to state property.

Which of the following would NOT serve as effective evidence to support the group's position?


A. Statistics showing a significant decrease in traffic accidents in regions where mobile phone use while driving is banned
B. Official police reports linking mobile phone use to specific traffic accidents
C. Research studies on the impact of multitasking on driving safety
D. Data from mobile carriers showing the number of phone calls made at speeds exceeding 30 km/h
E. Testimonials from drivers involved in accidents while using mobile phones


A. Statistics showing a significant decrease in traffic accidents in regions where mobile phone use while driving is banned.

Explanation: This is strong evidence supporting the group's position. If regions with a mobile phone ban while driving show a decrease in traffic accidents, it implies that such a ban could be effective in reducing accidents, thereby supporting the group's advocacy in State X.

B. Official police reports linking mobile phone use to specific traffic accidents.

Explanation: This is direct evidence supporting the group's position. Police reports that specifically attribute mobile phone use as a cause of accidents demonstrate a clear link between mobile phone use while driving and traffic accidents.

C. Research studies on the impact of multitasking on driving safety.

Explanation: These studies would likely provide scientific evidence about the dangers of divided attention while driving, such as using a mobile phone. This supports the group's argument by showing that multitasking, including phone use, impairs driving safety.

D. Data from mobile carriers showing the number of phone calls made at speeds exceeding 30 km/h.

Explanation: This data is not conclusive evidence that drivers are using mobile phones. The speed at which a mobile phone is moving does not necessarily indicate that it's being used by a driver. It could be used by passengers in a vehicle or by individuals in public transport, hence it does not directly support the group's position.

E. Accounts from drivers involved in accidents while using mobile phones.

Explanation: Personal testimonials from drivers who have had accidents while using their mobile phones provide anecdotal evidence supporting the group's claim. These accounts can be powerful in illustrating the real-life dangers of mobile phone use while driving.


Answer: D

Greetings!
I agree with D being the correct answer. In fact, I chose D as my answer. But I cannot stop wondering about C. It talks about research studies on the impact of multitasking on driving safety.
Can anyone help me with the information why we are attrituting impact to be negative?
As we don't know the result of the study, couldn't it be negative, no impact or a positive impact(Not speaking generally, but as it is just a research study, what if the result surprisingly came out to be supporting driving while using mobile phones as they showed more vigilance towards driving while multi-tasking than usual OR that multitasking they studied didn't involve mobile phone using at all)?
Maybe I'm overthinking but I cannot find a strong reason to reject C. HELP!

Hi. I think you are overthinking it just a tiny bit. One reason is that I cannot see how the results of a study about the impact of multi-tasking on driving would come out in any way other than negative. Imagine the study: 1) You drive without using the phone and 2) You drive while texting and watching YouTube. Which will be safer? :lol: I don't see a scenario where multi-tasking can consistently be a better outcome for a large number of casual drivers, so you can assume that it is going to be a pretty negative result.

P.S. I can put into the answer choice "negative impact of multi-tasking" I don't think it will be any less giving away than it already is since that's a widely held belief.

hi, thinking out loud - isnt multitasking too broad? Does it have to involve use of phone? My logic was that we cant ascertain if it involves phone use - if it involves phone use then yes, if it doesnt then it doesnt necessarily help us with evidence? thoughts?

Hi BB,

I thought this way " speeds exceeding 30 km/h" then we are not sure cause of accident is actually smart phone or speeding. So I got this correct luckily.

Hi. For D) it is not just accidents, but all drivers and you would not know which phone number was actually involved in the accident and also, how is that going to help if you are on a freeway where the speed limit is 100 km/h? This is really unclear and ambiguous data point.

Thank you for the question. Using a phone is a part of multi-tasking so it is OK to not name phone use exactly since phone use falls into the category and is included, even if the category is broad.
