The scientist is afraid that the _____________________ glaciers will cause water levels to rise, resulting in flooding. *5 pointsimprudentdisarmingreceding

The most appropriate word to fill in the blank is "receding."

This is because "receding glaciers" indicates that glaciers are melting and shrinking, which indeed contributes to rising sea levels, potentially leading to flooding.

Explanation of Other Options:

1. Imprudent: This adjective describes a lack of caution or foresight, which doesn't directly relate to the condition of glaciers impacting water levels.

2. Disarming: This term generally refers to something that removes suspicion or hostility, often in a psychological or emotional context, and is not relevant to glaciers or environmental issues.

Thus, the complete sentence would read: "The scientist is afraid that the receding glaciers will cause water levels to rise, resulting in flooding."
