Question #N810

The author, a skilled neuroscientist, recounts the events that led her to this discovery. She notes that scientists in the field had long believed the opposite was true, but she was skeptical of this belief because she had personal experience that contradicted it. What is the purpose of the last sentence of the passage?

The last sentence of the passage is most likely intended to
A. conclude the passage by providing an example.
B. emphasize the importance of the author’s personal experience.
C. introduce the author’s next line of reasoning.
D. explain the author’s disbelief in the traditional belief.

Correct Answer is: D

The last sentence, "because she had personal experience that contradicted it," directly explains the author's doubt about the traditional belief. The author provides no additional examples or reasoning in the passage, nor does the author focus on the importance of her personal experience.
