There is substantial evidence that certain forms of solar energy either now or within a few years will be economically competitive with conventional sources of heat and power.
(A) either now or within a few years will be economically competitive with conventional sources of heat and power
(B) will either be economically competitive with conventional sources of heat and power within a few years or are so now
(C) will be economically competitive with conventional sources of heat and power either now or within a few years
(D) either are now economically competitive with conventional sources of heat and power or will be so within a few years
(E) are either now or will be within a few years economically competitive with conventional sources of heat and power
I have seen discussion threads but I still have one question, and hope an expert can help me out. With answer D, the two branches "either..or" should read separately, and you get the following
1) There is substantial evidence that certain forms of solar energy are now economically competitive with conventional sources of heat and power
2) There is substantial evidence that certain forms of solar energy will be so within a few years
With 2) does the word "so" act as a pronoun referring back "economically competitive with conventional sources of heat and power"
Appreciate any assistance - Thanks
