The elevation factor EF is defined as EF = R / (R + H + N). In the denominator, which terms are added to R?

• A. H and N
• B. H only
• C. N only
• D. H and R

Answer: (A)

The question hinges on reading the formula correctly. EF is defined as R divided by (R plus H plus N). The denominator explicitly shows R plus two additional terms, H and N. So the terms added to R are H and N. Those additions inside the parentheses raise the denominator, which changes the value of EF compared to using R alone.
