Read the passage about nuclear energy.

According to the information in the passage, what could be an advantage of using nuclear energy?

• A. Using more nuclear energy means that less coal, oil, and gas needs to be burned in power plants to satisfy overall demand for electricity.

• B. Using more nuclear energy means that less heat will need to be created in power plants to satisfy overall demand for electricity.

• C. Using more nuclear energy means that more coal, oil, and gas needs to be burned in power plants to satisfy overall demand for electricity.

• D. Using more nuclear energy means that more carbon dioxide will need to be created in power plants to satisfy overall demand.

Answer explanation

If energy demands stay the same, an increase in the use of nuclear energy will result in a decrease in need for the other steam-electric plants.

The graph shows the range of amounts of carbon dioxide (CO2) given off to produce one kilowatt/hour for different methods of electricity production.

How does the amount of carbon dioxide given off by nuclear power compare with the amount of carbon dioxide produced by other sources of energy?

• A. Nuclear power produces the second lowest amount of carbon dioxide in the graph.

• B. Nuclear power produces the second highest amount of carbon dioxide in the graph.

• C. Nuclear power produces less carbon dioxide than all other sources of power in the graph.

• D. Nuclear power produces more carbon dioxide than all other sources of power in the graph.

The diagrams shows a nuclear reaction.

What type of reaction is shown in the diagram?

• A. Fusion, because the reaction released energy

• B. fission, because the reaction absorbed energy

• C. fusion, because the reaction formed heavier nuclei

• D. fission, because the reaction formed lighter nuclei

Answer explanation

The reaction shown is fission because the nucleus of an atom is split into two smaller, lighter nuclei.
