Question 14

They should do so, because radon is now considered to be one of the causes of lung cancer.

Checking for radon is essential as it is a known health risk associated with lung cancer. Advising the buyers to test for radon demonstrates due diligence in ensuring their safety and well-being in the home they plan to purchase.

A) it is unlikely that radon would be a problem in that area

This option is incorrect because it downplays the risks associated with radon, which can be present in any area regardless of previous assumptions or generalizations. It is important to conduct a test rather than rely on assumptions about the likelihood of radon presence.

B) as long as they are non-smokers, it should not be an issue

This response is misleading as it suggests that being a non-smoker eliminates the risk of radon-related health issues. Radon is a carcinogen that can affect anyone, regardless of smoking status, and therefore testing for it is crucial.

C) they should do so, because radon is now considered to be one of the causes of lung cancer.

This is the correct answer. Radon is recognized as a significant health risk and a leading cause of lung cancer, making it imperative for prospective buyers to test for its presence in their potential new home.

D) they need not do so, because if radon were present, there would be an odor that would make it easy to detect.

This option is incorrect because radon is colorless, odorless, and tasteless, meaning it cannot be detected by human senses. Relying on odor as a detection method is misleading and dangerous, emphasizing the necessity of testing.

Conclusion

The correct answer emphasizes the importance of testing for radon due to its classification as a health risk linked to lung cancer. All other options either underestimate the potential danger or provide incorrect information about radon's detectability, reinforcing the necessity of proactive measures for safety in home purchases.
