The only metal in which the United States is self-sufficient, molybdenum, is a self substance that can, paradoxically, be used to harden steel in alloys, as well as a lubrificant, and in trace amounts in nutritional supplements to help prevent tooth decay.

a- to harden steel in alloys, as well as a lubrificant, and in trace amounts in nutritional supplements.

b- to harden steel in alloys, as well as a lubrificant, and in trace amounts in nutritional supplements in trace.

c- in alloys to harden steel, as well as a lubrificant and nutritional supplements in trace amounts.

d- in alloys to harden steel, it can also be used a lubrificant and, in trace amounts, as a nutritional supplement.

e- in alloys to harden steel, it can also be used as well as a lubrificant and nutritional supplement in trace amounts.


The answer is D and I think there is a typo in D because it should be as a after the "used"


I eliminated A and B because how can you harden steel in alloys, it can be used in alloys to harden steel.

C and E are out because if we are using as well as , there should be only one thing and that has to be singular too. "as well as" is an additive phrase like an and, so using the and after another already existing additive phrase is not good.

NONE.

D and C are run-on. A,B and C are not ||. But if I have to select them I will go with C.

I beg to differ. No way this could be D or E.

Both have run-on problem.

:btw there are typos in the question. Commas highlighted are semi-colons. If this is the case then run-on problem in D is resolved and its the best choice.

Please don't mind but you should NOT be happy because D and E have run-on problems and could not be answer if typos are not corrected.

As written, all answers are incorrect. But I have a strong hunch that (D) has one critical typo and therefore shoud read:

in alloys to harden steel, it can also be used as a lubricant and, in trace amounts, as a nutritional supplement.

As moderators we could make the necessary revision if Pedro can't provide the OA.
