Answer:
The page shares personal information with other agencies.
Step-by-step explanation:
A page that does not secure information shared with it is definitely an unreliable website and it will not be safe for Chloe to share her family's history of heart disease with such a website. They might share such an information with agencies that Chloe might not approve of.
A reliable website will provide true and current information on the subject Chloe asks about. The information provided will also be from accredited sources that have a background in the subject matter.
