If additional sources of deuterium are found, it will expand the amount that can be used as heavy water for nuclear reactors and reduce the cost of energy, even if the sources are not immediately mined.


(A) it will expand the amount that can be used as heavy water for nuclear reactors and reduce the cost of energy

(B) that amount that is able to used as heavy water for nuclear reactors will expand and the cost of energy will be reduced

(C) it will cause an increase in the amount that is able to be used as heavy water for nuclear reactors and a reduction in the cost of energy

(D) the amount that can be used as heavy water for nuclear reactors will increase and the cost of energy will drop

(E) it will increase the amount of deuterium that can be used as heavy water for nuclear reactors and cause a drop in the cost of energy

(A) it will expand the amount that can be used as heavy water for nuclear reactors and reduce the cost of energy
--The usage of it is incorrect , the subject is plural (sources ) , it on the other hand is singular

(B) that amount that is able to used as heavy water for nuclear reactors will expand and the cost of energy will be reduced
--The construction is awkward ,
--The sentence seems to say that the amount will expand and cost will reduce

(C) it will cause an increase in the amount that is able to be used as heavy water for nuclear reactors and a reduction in the cost of energy
--same issue as A

(D) the amount that can be used as heavy water for nuclear reactors will increase and the cost of energy will drop
--Correct

(E) it will increase the amount of deuterium that can be used as heavy water for nuclear reactors and cause a drop in the cost of energy
--Same as A

MANHATTAN REVIEW OFFICIAL EXPLANATION:



Amounts do not expand, they increase. Eliminate A and B. The ‘it’ at the start of C is a pronoun without a clear reference. E has the same problem. Choice D is the correct answer.
