Question

An article in a magazine states that the people who work in uranium mines are likely to suffer from diseases. Which of these is the most reliable method to verify the information provided by the magazine?

a. ask scientists to analyze the effects of radiation on humans
b. ask geologists to test the harmful radiations emitted by uranium
c. ask doctors to treat patients who have never worked in uranium mines
d. ask uranium mining companies to check the radiations emitted in their mines

Answer 1

I would say the correct answer is A. ask scientists to analyze the effects of radiation on humans.
If those people who work in uranium mines are analyzed, then the scientists will know if and how much the effects of uranium on them are dangerous and causing diseases. I don't think the other options will be as effective as the first one.
