Answer :
Final answer:
Market failure due to information asymmetry is apparent in this situation, where homeowners are unaware of potentially dangerous levels of radon in their homes.
Explanation:
The situation described is an instance of a market failure, specifically related to information asymmetry. Information asymmetry is a form of economic problem where one party has more or better information than the other. In this case, the Smiths and their neighbors lack the information about the potentially unsafe levels of radon in their homes. This is a health concern because radon is a colorless, odorless gas that can cause health problems such as lung cancer over long periods of exposure. Because the homeowners are unaware of the issue, it may not be addressed, leading to potential health risks.
