Rearrange the following sentence to form a meaningful passage:
1. Solar energy is one of the most promising renewable energy sources.
2. It has a minimal environmental impact compared to fossil fuels.
3. Solar panels convert sunlight into electricity.
4. However, energy storage remains a significant challenge for solar energy systems.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 1-2-4-3.
Logical flow:
1: This is the opening sentence as it introduces the main subject, solar energy, and provides a general definition or status.
2: This follows 1 logically by adding a positive characteristic of solar energy, explaining its minimal environmental impact.
4: This introduces a contrast using the word "However," shifting the focus from the benefits to a significant challenge, which is energy storage.
3: This sentence explains the functional aspect of how solar panels convert sunlight, providing a technical detail that concludes the thought process of the passage.
Correct sequence: 1 → 2 → 4 → 3
Final Sentence/Passage: Solar energy is one of the most promising renewable energy sources. It has a minimal environmental impact compared to fossil fuels. However, energy storage remains a significant challenge for solar energy systems. Solar panels convert sunlight into electricity.
Hence, the chosen option is correct.
