People’s television-viewing habits could be monitored by having television sets, when on, send out low-level electromagnetic waves that are reflected back to the television sets. The reflected waves could then be analyzed to determine how many people are within the viewing area of the television sets. Critics fear adverse health effects of such a monitoring system, but a proponent responds, “The average dose of radiation is less than one chest x-ray. As they watch, viewers won’t feel a thing.”
Which of the following, if true, is the most direct criticism of the proponent’s response?
A. The system cannot determine whether persons in the viewing area are paying attention to what is being broadcast.
B. It is possible to gather reasonably useful data on who is watching programs by having selected families keep diaries of television watching.
C. Some of those who would watch television sets with the monitoring device on are already ill with conditions that keep them at home.
D. Even recipients of large, harmful doses of radiation do not sense the radiation as it strikes the body.
E. Because it would invade privacy, acceptance of the monitoring device would have to be voluntary on the part of viewing families, and that restriction would skew the results.
