A team of educational researchers at a University wanted to assess the relation between studying late at night with the performance of the students. Currently the classes at the University start very early in the morning, not encouraging the students to study late at night. However the researchers allowed a group of volunteer students to arrive for their classes late in the morning for a period of three months during which they studied late at night regularly. It was observed that their performance significantly improved.
Which of the following options, if true, would have the strongest grounds against deciding, on the basis of the above assessment, to implement late start of classes in the morning at the University to improve the performance of the students?
A. The late start of the classes would also require significant and inconvenient changes in the timing for the administrative staff.
B. Only a few students who were high performers during their high school days when they had the habit of studying late at night volunteered.
C. Implementing certain state of the art teaching methods would substantially increase the performance of the students, comparable to that observed in the assessment.
D. The Dean of the University is not in favor of changing the current timing of the classes.
E. Late start of the classes also means that it would be more inconvenient for the students to arrive at the University using the more crowded public transport.

D. The Dean of the University is not in favor of changing the current timing of the classes.
E. Late start of the classes also means that it would be more inconvenient for the students to arrive at the University using the more crowded public transport.
A. The argument deals with a relation between late study at night and performance of the students. Whether it is inconvenient for administrative staff to start late in the morning has no bearing on the relation discussed in the argument. This option may give a reason not to start the classes late in the morning, but it does not address the relation between late studies and performance.
B. Correct. This option states that only a few students who performed well when they studied late at night volunteered. The other students, who did not perform well or did not study late at night, did not participate in the assessment and hence for such students (who are the majority: “a few students… volunteered”), the outcome of starting the classes late in the morning is not known and thus the outcome of the assessment may not be indicative of the entire group.
C. The argument deals with a relation between late study at night and performance of the students. However, this option draws a relation between teaching methods and performance. This option may give a reason to implement a different way (state of the art teaching methods) to improve the performance, but does not strengthen or weaken the relation between late study at night and performance.
D. Opinion and reasoning are not the same. The opinion of the Dean has no role in establishing whether late study at night in general improves the performance of the students.
E. The argument deals with a relation between late study at night and performance of the students. Whether it is inconvenient for the students to reach the University has no bearing on the relation discussed in the argument. This option may give a reason not to start the classes late in the morning, but it does not address the relation between late studies and performance.
