Question

multiple-choice question
choose the answer that is not true
knowing the volumes of gases helps us to:
monitor climate change as a result of human activities
monitor the fertilizer needed to make plants grow
monitor the effects of gaseous pollutants on our health.
monitor global warming as a direct relation to the amount of $co_2$

Explanation:

• Monitoring climate change from human activities relies on measuring greenhouse gas volumes (e.g., $\text{CO}_2$), so this is true.
• Fertilizer needs for plants depend on soil nutrient levels, not gas volume measurements, so this is not true.
• Tracking gaseous pollutant volumes helps assess their health impacts, so this is true.
• Global warming is directly linked to atmospheric $\text{CO}_2$ volume, so monitoring this gas volume tracks warming, which is true.

Answer:

monitor the fertilizer needed to make plants grow
