Question : Assertion: Non-commercial energy sources are predominantly used in rural areas for household activities.
Reason: Non-commercial energy sources are locally available and easily accessible in rural regions.
Option 1: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Option 2: Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
Option 3: Assertion is correct, but the reason is incorrect.
Option 4: Assertion is incorrect, but the reason is correct.
Correct Answer: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Solution : The correct answer is (a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
The assertion states that non-commercial energy sources are predominantly used in rural areas for household activities, which is correct. Non-commercial energy sources, such as firewood, agricultural waste, and biomass, are often relied upon in rural areas for cooking, heating, and other household activities. These energy sources are more prevalent in rural regions due to various factors, including limited access to commercial energy sources, economic constraints, and the availability of local biomass resources.
The reason provided states that non-commercial energy sources are locally available and easily accessible in rural regions, and this is the correct explanation of the assertion. In many rural areas, non-commercial energy sources are abundantly available locally. Firewood, for example, can be sourced from nearby forests or agricultural lands, while agricultural waste can be readily obtained from farming activities. The accessibility of these energy sources is also relatively easier in rural regions, as households often have direct access to the biomass resources within their vicinity.
Therefore, both the assertion and reason are correct, and the reason serves as the correct explanation for why non-commercial energy sources are predominantly used in rural areas for household activities.
Question : Assertion: Non-commercial energy sources are primarily used in rural areas due to limited access to commercial energy.
Reason: Non-commercial energy sources are often available locally and require simple technologies for utilization.
Question : Assertion: Non-commercial energy sources, such as firewood and agricultural waste, are primarily used for cooking and heating in rural areas.
Question : Assertion: Commercial energy sources are widely used for industrial production and transportation.
Reason: Commercial energy sources are more cost-effective and have higher energy density compared to non-commercial sources.
Question : Assertion: Commercial energy sources, such as coal and natural gas, are extensively used for electricity generation and industrial purposes.
Reason: Commercial energy sources are readily available and have high energy density.
Question : Assertion: Non-renewable energy sources are finite and deplete over time.
Reason: Non-renewable energy sources are formed over millions of years through geological processes.
