search for yoga classes near his home
O search for information about meditation
O ask a friend who has taken a yoga class

Ask a librarian for help finding sources

Explanation:

Edward should ask for help of a librarian if he is having troubles finding information for his project.

If Edward wants to do historical research on on Yoga in the United States, he cannot get the needed information from searching for classes near his home. Yoga classes don't talk about the history of Yoga.

Also asking a friend wouldn't help his research because the friend is likely not born during the conception of Yoga so he wouldn't have first hand information about the history of Yoga.

Likewise searching for information about mediation wouldn't help Edward in his research.

Edward can only get the information he needs for his research by asking for help from a librarian. A librarian have access to historical books which can help Edward in his research. A library is a place where books (both historical and modern) are kept for use of the library users.
