D: <span>The author believed the tree had a life story, like a person.
The author spends the first bit of the paragraph discussing how important "place" or, setting, is to make a story enjoyable. Then he describes his biography of the tree. It is clear that he considers the tree to have a character and story of its own when he says "</span><span>It is, in truth, another form of character".</span>

The answer is 3. when creating a logistical argument, you state the idea that you are going against, and then you back yourself up on why you chose the opposing side.
I would say A or C would fit the role a topic sentence should play. Simply because B doesn't make sense unless given context with A. D doesn't make sense unless given context from A. So because of the lack of context between B and D if put in the first sentence, I would narrow it down to A or C. I'm assuming there is a was in between "Barbara" and "tired" within the first sentence. Hope that helps.
