Consider the set of northwestern states or provinces

{Montana, Washington, Idaho, Oregon, Alaska, British
Columbia, Alberta}. If a person chooses one element,
show that in three yes or no questions, we can determine
the element.

My three questions
Is there Salmon, Halibut, and Shark fishing in this state?
Is this state cold all year round?
Did the governor ran for vice presidency?

I have to draw a tree diagram to organize this. I do not know how to do it.
