Which of the following most logically completes the passage?

In cars, airbags provide good protection for the chest and head, but little or no protection for legs. A study of injuries resulting from car accidents showed that a large proportion were caused by blows to the legs. Therefore, if airbags protected this area, the risk of serious injury in car accidents would be greatly reduced, especially since......................... .


A. among the drivers included in the study's sample of injuries, only a very small proportion had been wearing an airbag at the time of accident.

B. even those drivers who drive cars with airbags have poor understanding of the degree and kind of protection that airbags afford.

C. an airbag that included protection for the legs would have to be somewhat larger and more expensive than current airbags.

D. although the bones in the legs are large, severe impacts in that area are very likely to cause serious injury, such as compound fracture.

E. drivers generally remain in their seat when they crash, which reduces the likelihood of severe impacts to the legs.

This is an Assumption Question. If you read the prompt carefully,
In cars, airbags provide good protection for the chest and head, but little or no protection for legs. A study of injuries resulting from car accidents showed that a large proportion were caused by blows to the legs. Therefore, if airbags protected this area, the risk of serious injury in car accidents would be greatly reduced, especially
since......................... .

There is no mention of Serious injuries in the whole prompt and the conclusion suddenly talks about the serious injury. So we have to find a bridge to fill this gap.

A. among the drivers included in the study's sample of injuries, only a very small proportion had been wearing an airbag at the time of accident - We are talking about prople who wear airbags. So this is Irrelevant

B. even those drivers who drive cars with airbags have poor understanding of the degree and kind of protection that airbags afford. - It does not matter whether the drivers know the degree of protection that the airbags offer. Even If they know, they can hardly do something about the damage caused to them

C. an airbag that included protection for the legs would have to be somewhat larger and more expensive than current airbags. - Cost is not discussed at all in the prompt. Irrelevant

D. although the bones in the legs are large, severe impacts in that area are very likely to cause serious injury, such as compound fracture. - Exactly bridges the gap as discussed

E. drivers generally remain in their seat when they crash, which reduces the likelihood of severe impacts to the legs. - Still legs are injured and the problem remains. Irrelevant

In Assumption Questions, It is very important to read the conclusion very carefully, word by word, and then think whether there are any gaps in the logic.

Clearly a strengthener question since a conclusion is followed by a premise indicator "since".

Choice D is clearly a strengthener.

OFFICIAL EXPLANATION:



Reading the question: we have a novel task in this question: we will complete the passage! The answer choices, as you can see, are not of a format such that they can be negated or analyzed by cases. Questions that ask for you for a logical continuation tend to have this problem, so, on logical continuation questions, the second step of the Critical Reasoning Strategy will usually not be possible (e.g., the answer choices cannot be negated), and you'll have to answer the question using only a filter.

Creating a filter: We are putting something in the blank that will complete the idea that bigger airbags that go down and cover the legs will reduce serious injuries. There is already evidence on the table; what's missing? We gravitate to the charged word "serious." The study cited in the prior sentence says "a large proportion" of accidents, but says nothing about their seriousness. So, what's missing and could go in the blank would be first of all, that the air bags will work in the leg area, and secondly, something about the seriousness of the accidents. That's our filter.

Applying the filter: Which answer choices fit either of these categories? Choices (A) through (C) do not. Choice (D) does. Choice (E) might. We take a closer look at (E). (E) discusses the likelihood of severe accidents in general, but it doesn't help us figure out whether specifically the accidents that have been happening and that an air bag will stop are severe. Back to (D). Choice (D) basically tells us, "Leg injuries are serious." This fills in one of the key missing pieces of the argument.

The correct answer is (D).
