@Minerva,

Let's look at the argument:

Certain instruments used in veterinary surgery can be made either of stainless steel or nylon. In a study of such instruments, 50 sterilizations of a nylon set required 3.4 times the amount of energy used to manufacture that set, whereas 50 sterilizations of stainless steel required 2.1 times the energy.

Which of the following statements CANNOT be true?

(B) says "More energy was required for each complete sterilization of the nylon instruments that was required to manufacture the nylon instruments."

If that were the case, 50 sterilizations would require 50+ times the energy used to manufacture, not merely 3.4 times.

Does that make sense?

Let me know if you have any further questions.
