PASSAGE
Researchers are investigating how dust accumulation impacts solar panel performance. The study shows that even a thin layer of dust can ______ the absorption of sunlight, significant reducing energy output.
Which choice completes the text with the most logical and precise word or phrase?
Detailed Explanation
The text explains that dust blocks sunlight, which in turn reduces the energy output of the solar panels. Therefore, the dust 'diminishes' or reduces the absorption of light.
Key Evidence:
• "impacting solar panel performance"
• "significantly reducing energy output"
Why others are wrong: A (Augment means to increase, which contradicts the idea that dust reduces output.), C (Maintain implies keeping it the same, but the text says output is reduced.), D (Clarify means to make clear, which doesn't fit the context of blocking sunlight.).
