PrepTest 156, Section 3, Question 26

Working the answers

• A
  Correct

  Koskan's company supplies the attempt, polyaspartate is the promising alternative, and polyacrylates are the existing product. Development and marketing cover the movement from a scientific insight to the practical question of getting industry to adopt it.

• B

  This makes mistakes the organizing focus. The author describes an economic barrier and a response to it, without presenting the account as a demonstration of errors. It also leaves out the positive evidence of promise and success.

• C

  Cost is one problem encountered, but the author isn't mainly using this case to teach a general lesson about the problems of marketing new products. Much of the account explains this chemical's particular advantages and applications. A captures that complete attempt more accurately.

• D

  The industry's withdrawal matters because it changes the prospects for polyaspartate. The author isn't primarily criticizing an industry's preference for profits over environmental innovation.

• E

  Some chemistry explains why polyaspartate is promising, especially its biodegradability. But a detailed account of chemical processes would not capture the later discussion of prices, companies, specialty markets, and future commercial prospects.
