If some one tells me a story about a time they went to an amusement park and they saw a ride brake down and the situation caused death or serious injury, i would understand why they would have fear of rides. if the story continued and they told me they went back to that same amusement park and got on more rides with his family that shows alot about this person and how the dont let the fear of playing the game strike them out.
I would say C because this passage talks about green building and how it's beneficial. Sentence 4 mentions about what the green roofs are made of and I don't think that would be necessary to include in this passage.
