The questions below are based on the reasoning contained in brief statements or passages. For some questions, more than one of the choices could conceivably answer the question. However, you are to choose the best answer; that is, the response that most accurately and completely answers the question. You should not make assumptions that are by common sense standards implausible, superfluous, or incompatible with the passage. Scientists have studied the effects of electromagnetic fields associated with high voltage power lines upon people whose homes are located within 300 yards of the lines. They have compared the growth rate of children who live near the lines with the growth rate of children who live elsewhere. Because they found no significant differences in the growth rates in the two study areas, they have concluded that electromagnetic fields are harmless.
Which one of the following, if true, would most seriously jeopardize the scientists’ conclusion?
  • a)
    The scientists did not consider other possible impacts upon growth rates.
  • b)
    In studying people who lived near high voltage power lines, the scientists did not consider what type of housing those people lived in
  • c)
    The growth rates of children have changed considerably since the 1920s.
  • d)
    People who live near electromagnetic fields suffer health problems that are not reflected in the growth rates of their children.
  • e)
    As children get older, their activities tend to occur away from home more often.
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
The questions below are based on the reasoning contained in brief sta...
(A) No. The study is concerned only with the effects of electromagnetic fields. Determining what other factors might impact children’s growth rates would be irrelevant to determining the effects of electromagnetic fields. (B) No. Since the growth rate for both groups of children was the same, it does not appear that the type of housing was important in determining the effects of exposure to electromagnetic fields. (C) No. The growth rate of children in the 1920s is insignificant to the purpose of this study to determine whether proximity to electromagnetic fields has any harmful effects. (D) Yes. The scientists assume that the only negative effect from living near electromagnetic fields would be a lower growth rate in children. Perhaps adults and children who live near the lines suffer from other ailments. These would not be reflected in a study of children’s growth rates and thus, this statement, if true, would seriously jeopardize the scientists’ conclusion. (E) No. Children’s growth rates were the same, so how much time children who lived near the power lines spent at home would appear to be irrelevant.

Understanding the Conclusion
The scientists concluded that electromagnetic fields from high voltage power lines are harmless based on their study comparing the growth rates of children living near these lines with those living farther away.
Key Point of Jeopardy
The conclusion hinges on the assumption that growth rates are the primary indicator of health effects related to electromagnetic fields. If other health issues exist, the conclusion may not hold.
Why Option D Jeopardizes the Conclusion
- Presence of Other Health Problems: If people living near electromagnetic fields suffer health problems not reflected in growth rates, this indicates that the scientists' study was incomplete.
- Growth Rate Limitations: Growth rates may not capture all health impacts, such as neurological or immune system issues, which could affect overall well-being.
- Misinterpretation of Data: The absence of growth differences could lead to a false sense of security about the safety of living near power lines, neglecting other potential health risks.
Comparison with Other Options
- Option A: While considering other impacts is important, it does not directly challenge the conclusion about growth rates.
- Option B: The type of housing could impact growth, but it does not specifically address the electromagnetic field's effects.
- Option C: Changes in growth rates over decades do not directly affect the study's findings.
- Option E: Shift in children's activities away from home does not correlate to their exposure to electromagnetic fields.
Conclusion
In summary, option D most seriously undermines the scientists' conclusion by highlighting the possibility of health issues unrelated to growth rates, suggesting a more complex relationship between electromagnetic fields and health.
