Harden steel and used as a lubricant are not parallel. The sentence has to be broken down. A, B and C are gone

E makes it look as if it can be used as a lubricant in nutritional supplements conveying a muddled sense. In addition, it is redundant to say ‘also ‘and ‘as well as.’

D is the answer

Can someone please explain C -

in alloys to harden steel, as well as a lubricant and , in trace amounts as a ...

in alloys - prep phrase?

to harden steel - infinitive phrase?

I felt its got to do with parallelism, but don't get the technical grammar behind this question...

Hi btg9788

I don't really get your question, but I guess your question is like "why C is wrong, and why D is correct"

C is wrong because of parallelism error.

...... molybdenum can be used [in alloys] to harden steel, as well as a lubricant and nutritional supplement in trace amounts.
The three bold parts are not parallel. Only "a lubricant" and "nutritional supplement" are parallel.

*in alloys - prep phrase? YES
* to harden steel - infinitive phrase? YES

D is correct. because:
......molybdenum can be used [in alloys] to harden steel; it can also be used as a lubricant and, in trace amounts, as a nutritional supplement
"It" modifies molybdenum correctly.
"as a lubricant" and "as nutritional supplement" are parallel.

Hope that helps.

Thanks pqhai.

I did not type my question correctly. However, at second glance, I see why the other answers are incorrect. In C, I think that its more to do with meaning rather than grammar or parallelism etc.

The element Molybdenum can be "a lubricant and nutritional supplement" to prevent tooth decay - Meaningless sentence.

So C changes the meaning to something like Molybdenum acts as a lubricant+nutritional supplement to prevent tooth decay, which clearly is nonsensical.

Parallelism of course, as you said is missing in C.

a. to harden steel in alloys, as well as as a lubricant, and in trace amounts, in the nutritional supplements

b. to harden steel in alloys, as well as a lubricant, and a nutritional supplement in trace amounts

c. in alloys to harden steel, as well as a lubricant and nutritional supplement in trace amounts

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

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


the sentence mention "paradoxically" but in D, paradoxically doesn't stand for anything, as now we have 2 independent clause. in 1st statement itself should itself why it is paradoxical. Am I wrong?
