17. Certain instruments used in veterinary surgery can be made either of stainless steel or of nylon. In a study of such instruments, 10 complete sterilizations of a set of nylon instruments required 3.4 times the amount of energy used to manufacture that set of instruments, whereas 50 complete sterilizations of a set of stainless steel instruments required 2.1 times the amount of energy required to manufacture that set of instruments.
If the statements above are true, each of the following could be true EXCEPT:
(A) The 50 complete sterilizations of nylon instruments used more energy than did the 50 complete sterilizations of the stainless steel instruments.
(B) More energy was required for each complete sterilization of the nylon instruments than was required to manufacture the nylon instruments.
(C) More nylon instruments than stainless steel instruments were sterilized in the study.
(D) More energy was used to produce the stainless steel instruments than was used to produce the nylon instruments.
(E) The total cost of 50 complete sterilizations of the stainless steel instruments was greater than the cost of manufacturing the stainless steel instruments.

Strange question!
does one set of nylon instruments contain same number of instruments as one set of steel instruments?

I would go for C....Who knows the number of instruments in a set?

(A) The 50 complete sterilizations of nylon instruments used more energy than did the 50 complete sterilizations of the stainless steel instruments.
- Possible. Nylon could use more energy than stainless steel based on the passage
(B) More energy was required for each complete sterilization of the nylon instruments than was required to manufacture the nylon instruments.
- Possible. Nylon could use more energy than stainless steel based on the passage
(C) More nylon instruments than stainless steel instruments were sterilized in the study.
- We can't predict that.
(D) More energy was used to produce the stainless steel instruments than was used to produce the nylon instruments.
- It could be. The sterilization energy was based on it's own manufacutring energy
(E) The total cost of 50 complete sterilizations of the stainless steel instruments was greater than the cost of manufacturing the stainless steel instruments.
- Possible. If the manufacturing energy is higher, cost would go up as well
C for me.

should be B.
C is possible coz we do not know how many times experiment was repeated.

.
-------------------------- sterialization ------------manufacture
-------------------------------------------------------------------------------
nylon--------------------- 0.34x ---------------- x
stainless steel----------- 0.042y --------------- y
the energy required for each complete sterialization of the nylon instruments is always smaller than the energy required to manufacture the nylon instruments.
I go for B.

I go for B. B for the same reason and explained above.
