Facts / premiseIn 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.
conclusion: if airbags protected this area, the risk of
serious injury in car accidents would be greatly reduced
since: answer must provide support for the conclusion
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.
irrelevant/not support the conclusionB. even those drivers who drive cars with airbags have poor understanding of the degree and kind of protection that airbags afford.
irrelevant/not support the conclusionC. an airbag that included protection for the legs would have to be somewhat larger and more expensive than current airbags.
irrelevant/not support the conclusionD. although the bones in the legs are large, severe impacts in that area are very likely to cause serious injury, such as compound fracture.
correct answer: this provides support to the conclusion
E. drivers generally remain in their seat when they crash, which reduces the likelihood of severe impacts to the legs
irrelevant/not support the conclusion: this option actually weakens the conclusion by saying crash reduces the likelihood of severe impact
