Which constraint is driving the interest in extracting useful chemicals from pomace?

-There is a limited amount of energy available for extracting resources.

-The chemicals derived from pomace are in short supply.

-Pomace is a pollutant that is expensive to clean up and extracting resources reduces pollution and costs.

-Pomace is available in greater quantities than needed for traditional uses and would be wasted.✅?

D. Pomace is available in greater quantities than needed for traditional uses and would be wasted.

The correct answer is: "Pomace is available in greater quantities than needed for traditional uses and would be wasted."

To arrive at this answer, we need to think about the factors that drive the interest in extracting useful chemicals from pomace. Here's a breakdown of the options:

- "There is a limited amount of energy available for extracting resources": This option does not directly relate to the extraction of chemicals from pomace.

- "The chemicals derived from pomace are in short supply": This option suggests that the chemicals derived from pomace are scarce, which is not the case.

- "Pomace is a pollutant that is expensive to clean up and extracting resources reduces pollution and costs": While this option highlights the environmental and cost-saving benefits of extracting resources from pomace, it does not directly address the motivation behind the interest in extraction.

- "Pomace is available in greater quantities than needed for traditional uses and would be wasted": This is the more likely constraint driving the interest in extracting useful chemicals from pomace. If pomace is available in excess and would otherwise go to waste, it makes sense to extract valuable chemicals from it.

Therefore, option 4 is the correct answer.
