Answer: [C]: " percent of resource emitted into the atmosphere ."
________________________
Explanation:
In the "Environmental Master Equation"—
Note that the:
"Environmental impact" ;
＝ (population) * (resource use per unit population) *
(environmental impact per unit of resource use) .
________________________
The question asks:
"The Environmental Master Equation includes all of the following terms —EXCEPT ...[with 4 (four) answer choices following.]."
________________________
Consider the given answer choices:
[A]: "resource user per person"—which is the same as"
"(resource use per UNIT [emphasis added] population" ;
— which does appear in the equation;
→ so we can rule out "Choice: [A]."
________________________
[B]: "population" —this is included within the equation; so we can rule out "Choice: [B]."
________________________
[C]: "percentage of resource emitted into the atmosphere" ;
Note: This clearly does NOT appear within the equation; so this is a likely answer choice.
________________________
Note: There is one more answer choice—so let us examine:
________________________
[D]: "environmental impact per unit of resource use" —this is included within the equation, so we can rule out "Choice: [D]."
________________________
Furthermore, the particular answer choices given—A, B, and D ; constitute all elements within the "Environmental Master Equation."
________________________
As such: The correct answer is:
[C]: "percent of resource emitted into the atmosphere."
