Consider this passage revision. Paragraph 1: A psychology class compared two note-taking methods during a unit on memory. Half the class used laptops, and half wrote notes by hand. Paragraph 2: At the end of the unit, students compared quiz scores and reflected on how each method affected their attention. The class then discussed the results. Which choice most effectively begins Paragraph 2 by linking it to Paragraph 1 and preparing readers for how the class gathered evidence about the two methods?
