Q: What is the total energy produced by non-renewable sources (Coal, Natural Gas, Nuclear)?

Correct Answer: Option C (5,760 TWh). Non-renewables = 38% (Coal) + 22% (Gas) + 12% (Nuclear) = 72%. Amount = 72% of 8,000 = (72/100) * 8000 = 5,760 TWh.

Q: What is the central angle for Renewables and Hydro combined?

Correct Answer: Option B (100.8°). Combined % = 20% (Renewables) + 8% (Hydro) = 28%. Central angle = 28% of 360° = 100.8°.

Q: What is the absolute difference in energy production between Coal and Natural Gas?

Correct Answer: Option C (1,280 TWh). Difference = 38% (Coal) - 22% (Gas) = 16%. Absolute difference = 16% of 8,000 = (16/100) * 8000 = 1,280 TWh.

Q: If Renewable energy production doubles next year while all other sources produce exactly the same amount as this year, what will be the new total global energy production?

Correct Answer: Option C (9,600 TWh). Current Renewables = 20% of 8000 = 1,600 TWh. If it doubles, it adds another 1,600 TWh. New total = 8,000 + 1,600 = 9,600 TWh.

Q: What is the ratio of energy produced by Coal to energy produced by Nuclear?

Correct Answer: Option C (19:6). Coal = 38%. Nuclear = 12%. Ratio = 38 : 12 = 19 : 6.
