Question 1:

Which of the following is true about nuclear energy?

- A. They release substantial amounts of greenhouse gases
- B. They emit carbon dioxide but no nitrous oxides
- C. They produce electricity without emitting carbon
- D. They are weather-dependent

#### Solution:
From the text:
- Nuclear reactors produce electricity without emitting carbon, unlike fossil fuels like coal and oil.
- This is explicitly stated under the "Advantages of Nuclear Energy" section: "Nuclear reactors produce electricity without emitting carbon."

Thus, the correct answer is:
C. They produce electricity without emitting carbon

Question 2:

What is a key advantage of modern nuclear power stations mentioned in the text?

- A. They are only certified for 50 years of operation
- B. They are dependent on weather conditions
- C. They can generate power consistently for 80 years
- D. They are less reliable than traditional gas-fired stations

#### Solution:
From the text:
- Modern nuclear power stations are certified for 80 years of operation, which surpasses the operational life of traditional gas or coal-fired stations.
- This is explicitly stated under the "Advantages of Nuclear Energy" section: "Some modern nuclear power stations are certified for 80 years of operation."

Thus, the correct answer is:
C. They can generate power consistently for 80 years

Question 3:

How does nuclear energy contribute to the reduction of emissions?

- A. By releasing substantial amounts of greenhouse gases
- B. By emitting carbon dioxide but no nitrous oxides
- C. By producing electricity without emitting carbon
- D. By being weather-dependent

#### Solution:
From the text:
- Nuclear energy contributes to reducing emissions because it produces electricity without emitting carbon. This makes it a cleaner alternative to fossil fuels, which release substantial amounts of greenhouse gases like carbon dioxide (CO₂) and nitrous oxides (NOₓ).

Thus, the correct answer is:
C. By producing electricity without emitting carbon
