Educator: Despite claims that books offer a better reading experience than electronic readers, a recent study found 90% of subjects demonstrated an increased ability to recall facts when that material was presented on an electronic reader rather than on the printed page. Therefore, if the reader hopes to have a deeper understanding of the material he or she is reading, that person should study using an electronic reader.

Which of the following calls into question the conclusion of the educator?

A:The ability to recall information while taking part in a study is similar to the ability to recall information when one reads for leisure.

B:Reading comprehension depends on how well one is able to connect facts not on how well one is able to recall facts in isolation.

C:Electronic readers may be filled with hyperlinks, which can be highly distracting.

D:Those who claim that reading on actual paper improves retention rate cite the importance of where on the page text is located.

E:Amongst adults, electronic readers are quickly displacing books as the preferred medium for reading.
