Answer: D: A particular viewpoint
When you put a “spin” on something, it means to look at something in a different way, or with a “particular viewpoint.” This can be a positive or negative spin. Already, only choice D makes sense, but now let’s also look at the adjective that describes “spin” in the sentence. “Positive spin.” If we are putting a “positive spin” on teenage years’ traumas, then we are looking at them in a different way or with a particular POSITIVE viewpoint. Choice D is the answer most close to this. The rest of the answers describe different words.
