Hey!
----------------------------------------------------
Part A:

When Samara came up with the idea of creating a new park she didn't know anything about how she would come up with an idea and presenting it to the zoning board.
----------------------------------------------------
Part B:

What I said above is what the answer is to Part B. If Samara wouldn't have gone to the library to learn how you would present an idea to the zoning board she would have never been able to create the park at all.

Hope This Helped! Good Luck!
