Breathing smoke produced by trucks, buses, and cars harms human health. The Brazilian Traffic Code provides actions to prevent this harm by:

1. controlling noise emissions only
2. requiring the use of masks
3. setting fuel-consumption quotas
4. controlling gas and noise emissionsCorrect answer!

Explanation

The correct answer is option 4 (controlling gas and noise emissions). This question assesses Citizenship and environment; this alternative directly meets the conditions in the prompt and the road-safety rules. The other alternatives broaden, narrow, or depart from the stated conditions and therefore should not be selected. Under the current rule, the difficulty is 4 on a scale from 1 to 5.
