Question

question 26 (multiple choice worth 3 points) (lesson 4.6 lc) the risk of carbon monoxide poisoning can be reduced by never leaving a car running in a garage never backing a vehicle into a garage turning on the air conditioner keeping your ventilating system on the lowest setting

Explanation:

Carbon monoxide (CO) is produced by burning fuel (like in cars). Leaving a car running in a garage traps CO, increasing poisoning risk. Backing a vehicle into a garage doesn't inherently reduce CO risk (the act of backing doesn't stop CO production). Turning on an AC or keeping ventilation low doesn't address CO from car exhaust. So never leaving a car running in a garage reduces CO poisoning risk.

Answer:

A. never leaving a car running in a garage
