accident INCREASE fatality DECREASE

Paradox could be : either the accident number or the fatality number

option A: wearing seat belt==> increases safety, BUT not guarantee the no fatality ( indirectly we need to assume that seat belt will reduce fatality ==> assumption in the reasoning -----> could not be answer

option D: the accident is between the Humanless self-driving vehicle ==> clear reason for the less number of fatalities and increased number of accidents

Generally, fatalities are directly proportional to the number of accidents. this means that as the number of accidents increases, it is expected that the number of fatalities will also increase

However, In the Bumbletown region, the number of accidents increased but the number of fatalities decreased.

We need to find an answer choice that helps explain why

Let's take a look at the answer choices -

(A) Last year, out of all passengers that travelled on road, the proportion of passengers wearing a seat belt has been significantly higher than the year before. - Is wearing a seat belt a solid guarantee that even if you get involved in an accident, you may not suffer from fatal injuries? I don't think so. the extent of injury depends on many more external factors than a simple seat belt. A seat belt is designed to improve your chances of not suffering from serious injuries; it by itself is NOT a guarantee of complete safety. Hence, (A) is eliminated.

(B) Last year, there was a significant increase in the sales of the Government-approved safety guidelines book “How to drive safely to avoid an accident”. - Simply reading a book will lead to lower number of fatalities? I don't think so. Even if you might have read the book, what if the driver of the other car (that hypothetically collides with yours) hasn't read the book? This is not a solid option. Hence, eliminate (B)

(C) The proportion of emergency medical personnel in the country has increased last year. - This would increases your chances of survival (as would wearing a seat belt), but the existence of more emergency medical personnel is itself not a guarantee of lower fatalities. Hence, eliminate (C).

(D) Most of the road accidents last year were between the recently introduced self-driving cargo-carriers that were doing test runs without any human involvement.. (D) tells us that the collisions that took place in such accidents did not involve humans at all. This would help account for the decrease in the number of fatalities. Hence, (D) is the right answer.

(E) There has been a consistent decrease in the number of fatalities in road accidents over a five-year period before last year. - (E) is simply a premise. It does nothing to explain the observed link between the (increase in number of accidents) and (decrease in the number of fatalities). Hence, eliminate (E).

isn't option D written in an awkward way by introducing the word 'between' ?

The conclusion states that the no. of fatalities decreased as compared to last year but Option D does not tell us how the no.s actually decreased. It just gives us the answer to the statement that no. road accidents increased due to this testing.

Fatalities in road accidents are typically directly proportional to the number of road accidents in a country. In Bumbletown, the number of road accidents last year has increased by 15% compared to the year before. Clearly, the number of fatalities can be expected to increase by a similar proportion. However, government officials claim that the number of fatalities last year actually decreased compared to the year before.

Which of the following, if true, does most to justify the government officials’ claim?

(A) Last year, out of all passengers that travelled on road, the proportion of passengers wearing a seat belt has been significantly higher than the year before.
(B) Last year, there was a significant increase in the sales of the Government-approved safety guidelines book “How to drive safely to avoid an accident”.
(C) The proportion of emergency medical personnel in the country has increased last year.
(D) Most of the road accidents last year were between the recently introduced self-driving cargo-carriers that were doing test runs without any human involvement.
(E) There has been a consistent decrease in the number of fatalities in road accidents over a five-year period before last year.

Hi GMATNinja KarishmaB MartyTargetTestPrep

Could you please explain why Option A is incorrect and Option D is correct?

My thinking in selecting Option A was - that if the proportion of passengers wearing a seat belt was higher last year then fatalities should decrease. By general knowledge, seat belts reduce serious injuries, so passengers who have accidents will likely have fewer injuries and, hence, fewer fatalities.

Is A wrong because we don't know if people who met with accidents were not a part of the proportion who wore seat belts?
For ex: 35 out of 100 wore seat belts the year before last year, and 55 out of 100 wore belts last year, maybe people who had accidents last year were mainly from the remaining 45 out of 100, hence, the possibility for fatalities remains and doesn't explain the paradox in the argument.

Option D is wrong - "without any human involvement" doesn't necessarily mean that no human is present on the seat other than the driver seat. Ideally, self-driving cargo carriers will have no driver but other passengers should be present on different seats so these passengers will have serious injuries/fatalities during collisions.
Is this assumption the only mistake behind my elimination?

Please let me know if something is wrong here in my thoughts.
