- The desire to have the purest possible product favors the use of ethanol over water

Answer 1

I can't argue with your choice; however, doesn't much of the decision depend upon WHAT you consider a useful product. Furthermore, company A may have a list of useful products that are different from Company B so the impact may be considerably different between the two companies. I think there are just too many unknowns to give a definite answer.

Answer 2

The answer is B, Organic Solvents are Expensive, which limits their use for extracting chemicals.
