If this question:
27. Whether the electromagnetic radiation generated by mobile phones threatens human health has always been a controversial topic. A study in 10 shows that people who use mobile phones for more than 30 minutes every day have a 40% higher risk of developing glial cancer than those who have never used mobile phones. Because some experts suggest that before obtaining further evidence, people should take safer measures, such as using fixed telephones or using SMS to communicate as much as possible.
Which of the following, if true, best shows that the expert's advice is unrealistic? ( )
A. The electromagnetic radiation intensity generated by most mobile phones meets the national standards.
B The existing electromagnetic radiation intensity of human living space has exceeded the electromagnetic radiation intensity generated by cell phone calls.
C. after a long time, people's physique gradually adapts to the environment of strong electromagnetic radiation.
D In the above experiment, some people use their mobile phones for more than 40 minutes every day, but they are healthy.
E. Even if we communicate by SMS, sending and receiving information will instantly generate strong electromagnetic radiation.
Even if we communicate by text message. Answer B (now humans ...) is a bit confusing. According to our understanding of the law of weakening questions in the course of Ou Kai Education, when B and E are undecided, we can use the principles of "approaching" and "tit for tat" to eliminate wrong answers. What is the purpose of this expert? It is to reduce the impact of radiation on human beings. According to the principle of "tit-for-tat", answer E tells us that the expert's plan cannot reduce the impact of radiation on human beings. According to the principle of closeness, e is closer to the topic than b.
