Statement: The use of solar energy has significantly increased in residential areas over the past 5 years.
Inferences:
1. People are becoming more environmentally conscious.
2. Solar energy is cheaper than all other sources of energy.
Show answer & explanation
Correct answer: A
Explanation
Analysis of the inferences:
• Inference 1: Solar energy is a clean, renewable, and eco-friendly source of energy. Its significant rise in residential adoption logically indicates that people are becoming more aware and conscious of environmental protection. Hence, Inference 1 follows.
• Inference 2: The statement makes no comparison between the cost of solar energy and all other energy sources. Stating that it is "cheaper than all other sources" is an extreme and unsubstantiated assumption. Hence, Inference 2 does not follow.
Therefore, Only Inference I follows.
