Option 1: Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Option 2: Both statement 1 and statement 2 are true, but statement 2 is not the correct explanation of statement 1 .
Option 3: Statement 1 is true, but statement 2 is false.
Option 4: Statement 1 is false, but statement 2 is true.
Correct Answer: Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Solution : The correct answer is (A) Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1.
Statement 1 is accurate in stating that renewable energy sources, such as solar and wind power, are crucial for achieving sustainable development and reducing greenhouse gas emissions. Renewable energy sources are considered environmentally friendly because they produce little to no greenhouse gas emissions during operation, unlike fossil fuels which are major contributors to climate change. By relying on renewable energy sources, we can reduce our dependence on fossil fuels and transition to a more sustainable and low-carbon energy system.
Statement 2 is also true in highlighting some advantages of renewable energy sources. Renewable energy sources, such as solar and wind power, are indeed abundant and can be harnessed from natural resources that are continuously replenished, such as sunlight and wind. They are also cleaner in terms of their carbon emissions compared to fossil fuels.
Therefore, both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
