LR Question 24 Explanation

QUESTION TEXT: Automobile emission standards are enforced through annual…

QUESTION TYPE: Weaken

CONCLUSION: Emissions standards testing is effective.

REASONING: Cars are tested while idling. Pollutants exiting the tailpipe are measured.

ANALYSIS: People don’t just sit idle in their cars all day. They generally drive them around.

Exhaust pollutants might change when the car moves. If so, the testing is not a good measure of how cars pollute.

___________

1. This shows that emissions control becomes expensive but it doesn’t really have anything to do with emissions testing. 
2. As long as the devices are recalibrated frequently then the testing should go smoothly.
3. CORRECT. Yikes. So by making a car clean while idling we are actually causing more pollution when the car moves. 
4. This doesn’t tell us whether the emissions standards are effective.
5. This shows the standards are strong because they don’t make exceptions for old cars. But…are the emissions tests effective? That’s the question.
