Question 10

Step1: Analyze Option A

Repairing a leaky faucet stops water from wasting, so it conserves water.

Step2: Analyze Option B

Watering lawn only at noon might not conserve water; it depends on evaporation, but it's not a direct conservation method like fixing leaks.

Step3: Analyze Option C

Washing clothes in the morning doesn't inherently conserve water compared to other times.

Step4: Analyze Option D

Letting water run while brushing teeth wastes water, so it's not conservation.

Step1: Analyze Option A

Automobiles emit pollutants that contribute to smog.

Step2: Analyze Option B

Factory pollution releases pollutants that cause smog.

Step3: Analyze Option C

Mountains surrounding urban areas can trap pollutants, leading to smog.

Step4: Analyze Option D

Since A, B, and C all contribute, D is correct.
