The Air Cushion Restraint System or airbag, as it is more commonly known, certainly does not function properly in most cases. A study conducted on the injury caused to drivers involved in accidents in which their vehicles were equipped with airbags showed that in seven out of ten cases the driver’s head was not prevented from hitting the steering wheel, the only function of the airbag installed in the dashboard.
Which of the following would it be most useful to consider while evaluating the claim made by the author above?
Argument Analysis
Pre-Thinking
Conclusion Clarification
The conclusion states that airbag certainly does not function properly in most cases because a study showed that in 7/10 cases the driver’s head was not prevented from hitting the steering wheel, the only function of the airbag installed in the dashboard.
Pre-Thinking Approach
In order to evaluate the linkage, we’ll pre-think assumptions by thinking of conditions that will falsify our belief in the conclusion. The assumptions then will be that these conditions don’t exist. To do so, let’s look at linkage 1 and understand the conditions under which it doesn’t hold.
Linkage#1 – A study conducted on the injury caused to drivers involved in accidents in which airbags were installed showed that in seven out of ten cases the driver’s head was not prevented from hitting the steering wheel, the only function of the airbag installed in the dashboard.
- Falsification Condition: What if, in an instance of an accident certain conditions need to be met in order to trigger an airbag to function? For example: certain crash sensors send signals to the airbag to function. Thus, if these censors are not working properly, the airbag wouldn’t get any signal to function. In absence of such signals, the driver’s head may not be prevented from hitting the steering wheel but in such a case, it cannot be concluded that airbag doesn’t function properly. Thus, the linkage will not hold.

- Assumption 1: In most of the accidents studied, there was no external factor that limited the proper deployment of the airbags.
An answer choice that evaluates any of the fundamental assumptions made by the author will be the correct choice.
With this pre-thinking in mind, let’s evaluate the answer choices.
Answer Choices
A
Whether in most of the accidents studied the drivers had been wearing their seat-belts at the time of the collisions
Incorrect - Irrelevant
Neither the choice nor the argument makes any link between wearing set-belts and the full functioning of an airbag.
B
Whether in most of the accidents studied the vehicles faced a front-end collision, a condition necessary for the deployment of airbags installed in the steering wheel or dash-board
Correct
This choice is written along the lines of our pre-thinking assumption. If the necessary condition for the deployment of airbags was met and still the driver’s head was not prevented from hitting the steering wheel the conclusion that airbags don’t work properly in most cases is strengthened. Otherwise, it is weakened.
C
Whether the airbags work efficiently in preventing the driver’s head from hitting the dashboard
Incorrect - Irrelevant
As the airbag’s only function is to prevent the driver’s head from hitting the steering wheel, whether or not it works efficiently in preventing the driver’s head from hitting the dashboard is not relevant.
D
Whether the drivers were aware that their vehicles had airbags installed in them
Incorrect - Irrelevant
The argument doesn’t tell us that the drivers need to set off the airbags. Thus, lack of awareness of the drivers cannot be linked with the functioning of the airbags.
E
Whether most of the drivers involved in the accidents studied were responsible for the collisions they were involved in
Incorrect - Irrelevant
Knowing who was responsible for the accidents doesn’t tell us why the driver’s head was not prevented from hitting the steering wheel in cars in which airbags were installed.
