Which object is most likely to become polluted when fertilizers are applied to neighborhood lawns? A. Air moving above the city B. Soil found under paved streets C. A pond containing runoff from rain D. A flower garden located in a park

## Step 1<br />The problem is asking us to identify which object is most likely to become polluted when fertilizers are applied to neighborhood lawns. The options provided are: A. Air moving above the city, B. Soil found under paved streets, C. A pond containing runoff from rain, and D. A flower garden located in a park.<br /><br />## Step 2<br />When fertilizers are applied to lawns, they can be washed away by rain or irrigation. This runoff can then enter nearby bodies of water, such as ponds, rivers, or lakes, leading to water pollution.<br /><br />## Step 3<br />Among the given options, a pond containing runoff from rain (Option C) is the most likely to become polluted due to fertilizers. This is because the fertilizers can be washed into the pond, leading to an increase in nutrients in the water. This can cause algal blooms, which can deplete oxygen in the water and harm aquatic life.<br /><br />## Step 4<br />Options A, B, and D are less likely to become directly polluted by fertilizers applied to lawns. Air moving above the city (Option A) is not directly affected by fertilizers on the ground. Soil found under paved streets (Option B) is not in direct contact with the fertilizers. A flower garden located in a park (Option D) is not typically affected by runoff from lawns unless it is very close to the lawn.
