PART A — ADVANCED READING COMPREHENSION
Passage 1: The Transition to Renewable Urban Grids
Modern metropolises face a dual burden: rising municipal energy demands and escalating climate impacts. Traditional power grids rely heavily on fossil fuels, which contribute significantly to urban carbon footprints. To combat this, urban planners in Aethelgard initiated a transition to decentralized renewable energy microgrids. By harnessing distributed solar panel arrays, localized wind turbines, and smart storage batteries, individual districts can generate and manage power independently.

Initial critiques highlighted the substantial upfront capital expenditure required to install smart storage batteries. Critics argued that public funds should instead be directed toward upgrading existing power lines. However, proponents emphasized that decentralized microgrids offer unparalleled resilience against regional blackouts caused by severe weather events. Following a three-year trial, districts equipped with microgrids experienced an 80% reduction in power disruptions, proving that long-term grid security outweighs initial installation costs.
1. What is the primary purpose of decentralized energy microgrids in Aethelgard?
2. What was the main criticism raised against the initial microgrid proposal?
3. The word "resilience" in paragraph 2 most nearly means...
4. What can be inferred from the outcome of the three-year trial?
5. Which statement best reflects the author's overall message?
Passage 2: The Controlled Experiment Dilemma
A team of high school biology students set out to determine whether adding organic compost to soil increases bean plant growth rates. They prepared four plant pots: Pot A received regular topsoil and full sunlight; Pot B received compost-enriched soil and partial shade; Pot C received topsoil mixed with sand and full sunlight; and Pot D received pure compost in total darkness.

After four weeks, Pot B exhibited the tallest seedlings. The students prematurely declared that organic compost is the single driver of plant growth. Upon reviewing the project, their biology teacher urged them to evaluate their experimental design before publishing their conclusions. The students realized they had failed to maintain standardized environmental conditions, as light exposure and soil composition varied simultaneously across all pots.
6. Why was the students' initial conclusion scientific invalid?
7. Which modification would ensure a controlled, fair test in a repeated trial?
8. What essential principle of scientific enquiry does this passage highlight?
9. What does Pot D's placement in total darkness illustrate?
10. What is the most suitable title for Passage 2?
