6. Which of the following best summarizes the main idea of the passage?
a. The sweeping changes in the use of biotechnology since 1972 have redefined its necessity to mankind.
b. Although still in its fledgling stages, biotechnology shows promise to help benefit our society one day.
c. As the science of biotechnology continues to broaden and strengthen, the fruits of its applications become more powerful and abundant.
d. The swapping of DNA could sometimes yield beneficial results, but on the whole is too risky to undertake.
e. The development of transgenic plants is paramount to the development of better pharmaceuticals.

Correct Answer: d

Answer Explanation:

The passage explores the uses of biotechnology since inception, which predates its study, up until its present, and how more recent findings continue to broaden the horizon of its advantages. Choice a is certainly a supporting idea of the passage, but would not qualify as the main idea. The answer is not choice b since the benefits of biotechnology are documented throughout the passage. The author clearly supports the continuance of this study, and never mentions risks or concerns, therefore choice d is incorrect. Choice e could also be inferred as true, but is a less significant point of the passage.
