The right answer is B.Premise: Biotechnology companies say that voluntary guidelines for their industry are sufficient to ensure that no harm will result when a genetically altered organism is released into the environment.
Counter-premise: It is foolish, however, to rely on assurances from producers of genetically altered organisms that their products will not be harmful.
Conclusion: Therefore, a biotechnology company should be required to apply to an independent regulatory board composed of scientists outside the biotechnology industry for the right to sell newly created organisms.
From the conclusion of the argument above, the author is of the view that a biotechnology company should not play the role of regulators and determine the right to sell their newly created organisms. If it is indeed unwise to rely on the assurances from producers of genetically altered organisms that their products will not be harmful, then the author must have assumed that the biotechnology companies involved in the production of genetically altered organisms may not be completely honest in their assessments, hence the assurances provided might be skewed in their interests.
Our task is to strengthen the argument above.
(A) Voluntary guidelines are sufficient to regulate activities that pose little danger to the environment. No, this does not strengthen the argument above. This is the position of the biotechnology companies involved in the manufacture of the genetically modified organisms and the argument above countered this position.
(B) People who engage in an activity and have a financial stake in that activity should not be the sole regulators of that activity. This is the correct answer as it is in line with the reasoning provided above on the argument.
(C) Methods that result in harm to the environment must sometimes be used in order to avoid even greater harm. This is irrelevant.
(D) A company is obligated to ensure the effectiveness of its products but not their environmental safety. Incorrect. This position is out of scope because the main crust of the argument is whether the biotechnology companies involved in the production of GMOs should be trusted to assess their own products.
(E) Issues of environmental protection are so important that they should not be left to scientific experts. No. This completely out of scope.
