When Emily wants to find out how to use her savings to make more money. She goes online and finds a great Web site about  doubling your money every day.

Unreliable and relevant

Explanation:

The reasons behind this answer are that at the first pace is relevant because she was looking for a place to use her savings to make more money. However, this is not a very reliable source of information because it is a random website and has no way to verify the authenticity and security of the operations that she could potentially make on it.  

all of them make sense but, i would have to say ask someone who has been there/or lives there, and/or read recent newspapers from that city.

hope this !
