B. Topics covered
Like Petersen et al. [9] and Sheard et al. [10], we consider
the topics covered in each question. However, unlike Sheard
et al. [10] we do not impose a maximum of three topics to
assigned to each question. As Petersen et al. [9] say, “The
mind is limited in its ability to work with multiple concepts
simultaneously”. Therefore, it is worth identifying all of the
topics that are covered in each question.
