The premise is that SUV are subject to only a small fraction of the safety standards the government imposes on ordinarly passenger cars.
The conclusion is that therefore, in a high-impact collision, SUV passengers are more likely to be injured.
5 says that the higher probability of SUV passengers be harmed may be due to some cause ( false sense of security ) other than SUVs' "non-compliance" to government standards. This may weaken the argument, or at least, not strenghten it by giving an alternative explanation.
4 does somewhat strenghten the argument. If SUVs are bulkier, then their manoeuverability can be reduced. Also, if the acceleration is hindered, then the ability to avoid such a collision (by quickly bifurcating elsewhere before the impact), may be hindered as well. Agree, that this is more inference but IMO, it could strenghten the argument more than 5 does.
1 is no good because it clearly strenghtens the argument by saying that because SUV car makers are not under the same safety standards, then they will no be inclined to make their cars safe ( they don't have to )
i have broken my head, while thinking about this question. i chose (b), thinking that the word "susceptable" means "stable" (not native speaker, shame on me..
). the answer is (d). explanation arrives:
before we discuss the answer to this strengthen EXCEPT question, it's important to make a point: four of the answer choices strengthen the argument, and one does not. that doesn't necessarily mean that this fifth choice weakens the argument. it just means that it does not strengthen it (it could be out of the scope). the argument says that people who drive SUVs are more likely to be injured in a car wreck, and (b), (c) and (e) strengthen the idea by asserting either that cars are safer or that SUVs are more dangerous. (d) is irrelevant (and therefore the best answer) because we don't know if a lack of acceleration makes a car any less safe to drive. (a) strengthens because the argument says that SUVs don't have as many safety standards: thus, SUV designers will cut corners if they can.
