Question

which statement describes a disadvantage of using natural gas as an energy source? it is expensive to use. it is hard to stop using. it is a renewable resource. it is scarce in some parts of the world.

Explanation:

• Analyze each option:
• "It is expensive to use": Natural gas is relatively affordable compared to some other energy sources, so this is incorrect.
• "It is hard to stop using": This is not a typical disadvantage related to its nature as an energy source; many energy sources can be hard to stop using due to infrastructure, but this is not a key disadvantage of natural gas specifically.
• "It is a renewable resource": Natural gas is a non - renewable fossil fuel, so this statement is factually wrong.
• "It is scarce in some parts of the world": The uneven distribution of natural gas reserves means that in some regions, it is not readily available, which is a disadvantage as it can lead to supply issues and higher costs in those areas.

Answer:

D. It is scarce in some parts of the world. (Note: Assuming the options are labeled A - D in order, with A being "It is expensive to use", B "It is hard to stop using", C "It is a renewable resource", D "It is scarce in some parts of the world")
