LR Question 2 Explanation, by LSATHacks

QUESTION TEXT: A large number of drivers routinely violate highway…

QUESTION TYPE: Necessary Assumption

CONCLUSION: We could prevent most accidents by stopping cars from going over the speed limit.

REASONING: Speeding is an important factor in most accidents.

ANALYSIS: The argument is assuming that we will never need to speed on a highway, for safety reasons. Have you ever had to speed up to avoid an accident?

___________

1. The devices might prevent accidents even if only trained mechanics could install them.
2. This doesn’t matter. It only matters that most accidents could be prevented if cars could no longer speed.
3. CORRECT. You might need to accelerate to get out of a dangerous situation, but the device installed in your car would prevent you from getting away. You would be hurt because of the device.
4. It doesn’t matter why drivers speed. The device will prevent both intentional and unintentional speeding.
5. The argument didn’t say that the devices were the only solution. The argument is fine as long as they are a solution.

Recap: The question begins with “A large number of drivers routinely violate highway”. It is a Necessary Assumption question. Learn more about LSAT Necessary questions in our guide to LSAT Logical Reasoning question types.
