Ohio Graduation Test for Science – Spring 2008 Annotated Item 8 Standard and Benchmark Assessed: Standard: Science and Technology Benchmark: B. Explain that science and technology are interdependent; each drives the other. Multiple Choice Question: Commentary: This multiple choice question asks students to identify the statement that correctly describes how concerns over environmental effects of DDT affected the field of agricultural science. Students need to recognize that the popularity of DDT was due to its effectiveness and the decline in use of DDT was due to the discovery that DDT was harmful to humans and the environment. The logical affect of the concern over potentially harmful environmental effects was the development of more effective, potentially less harmful, alternative pesticides. Answer choice C is the correct answer. Answer choice A is incorrect because after the realization that DDT was harmful to humans and the environment, the impact of pesticides would be more closely monitored and other, equally harmful, pesticides would not be developed.
