Final answer:
Patricia should address James's concerns about mold by recommending professional testing to determine if the mold is harmful and emphasizing the importance of addressing mold issues promptly.
Step-by-step explanation:
When James mentions his concern about black spots on the bathroom ceiling and wonders if it could be dangerous mold, Patricia should first acknowledge his concern and advise that mold can potentially be harmful. She should recommend that before making an offer on the property, James and Cindy should have the substance tested by a professional to determine if it is a harmful type of mold. It is not true that all molds are toxic and require immediate evacuation of a home. In fact, while some molds can be harmful to human health, particularly to those with allergies or compromised immune systems, many molds are quite common and not dangerous. However, Patricia should emphasize that it is essential to address mold issues promptly to prevent any potential health risks and property damage.
