Question

what is the main advantage of nuclear energy compared to fossil fuels, according to the slide?
the waste it produces is harmless.
it does not produce greenhouse gases.
the fuel source (uranium) is renewable.
it is the cheapest form of energy.

Explanation:

• Analyze each option:
• "The waste it produces is harmless" is incorrect as nuclear waste is hazardous.
• "It does not produce greenhouse gases" is correct because nuclear energy generation (fission) doesn't emit CO₂ or other greenhouse gases, unlike fossil fuels (which release them when burned).
• "The fuel source (uranium) is renewable" is wrong; uranium is non - renewable (a finite resource).
• "It is the cheapest form of energy" is incorrect as nuclear energy has high upfront costs (construction, waste management) and isn't the cheapest (e.g., solar or wind can be cheaper in some contexts, and fossil fuels like coal can be cheap in terms of production cost in some regions).

Answer:

B. It does not produce greenhouse gases. (Here we assume the purple option is labeled as B for the multiple - choice context, with the text "It does not produce greenhouse gases.")
