What is the risk of spraying up and down the tree trunks according to the policy?

• A. It Would Improve Pest Control
• B. It Would Be More Cost-Effective
• C. It Would Be Safer for Beneficial Insects
• D. It Would Cause Drift and Be Environmentally Irresponsible

Answer: (D)

The main idea here is that spraying up and down tree trunks creates drift and environmental risk. When the spray is directed upward, particles can be carried by wind to unintended areas, and when directed downward or along the trunk, residue can run off or settle where it’s not meant to, affecting nearby plants, water, and non-target organisms. This is why the policy flags it as environmentally irresponsible – it increases off-target exposure and potential harm to beneficial insects, wildlife, and the broader ecosystem.

That’s why choosing this option is best: it explicitly acknowledges the drift and environmental concerns tied to this method. The other ideas miss the key issue—improving pest control isn’t guaranteed, could be more costly, and the claim that it’s safer for beneficial insects contradicts the risk of off-target exposure.
