Question

which statement describes a disadvantage of nonrenewable resources?
it is hard to collect large quantities of them at a time.
they are inconsistent or unreliable as an energy source.
they are expensive to collect and transform into energy.
it is difficult to change the habit of using the resource.

Explanation:

To determine the disadvantage of nonrenewable resources, we analyze each option:

• Option 1: Collecting large quantities of nonrenewable resources (like fossil fuels) at once isn't typically a major disadvantage; extraction methods allow bulk collection in many cases.
• Option 2: Nonrenewable resources (e.g., coal, oil) are generally consistent and reliable as energy sources when used, so this is incorrect.
• Option 3: Nonrenewable resources (e.g., coal, oil, natural gas) often require costly extraction, refining, and processing to convert into usable energy, which is a key disadvantage.
• Option 4: Changing the habit of using a resource is more about human behavior/energy transition challenges, not a direct disadvantage of the nonrenewable resource itself.

Answer:

C. They are expensive to collect and transform into energy. (Note: Assuming the options are labeled as A, B, C, D with A being "It is hard to collect large quantities of them at a time", B being "They are inconsistent or unreliable as an energy source", C being "They are expensive to collect and transform into energy", D being "It is difficult to change the habit of using the resource". If the original labeling is different, adjust the identifier but the text remains the same.)
