Set 6: Words in Context (Intermediate)
Explanation
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 Answer Explanation
This question asks for the meaning of a word as used in this specific context. 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. Words can have multiple meanings, and context determines which meaning applies. Read the surrounding sentences carefully. Substitute each answer choice to see which maintains the intended meaning and fits the context. Many vocabulary words have multiple dictionary definitions, but only one fits the context. Use the surrounding sentences as clues. Try substituting each answer choice to see which one preserves the author's intended meaning without changing the sentence's message.
Key Evidence:
• "impacting solar panel performance"
• "significantly reducing energy output"
Why others are wrong: D (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.), A (Clarify means to make clear, which doesn't fit the context of blocking sunlight.).
