A student response survey found that students
who paid for 10 or more in-person tutoring
sessions on an hour-by-hour basis missed or
rescheduled a session on average once every
five sessions. By contrast, those students who
purchased tutoring sessions in ten-hour packages
missed or rescheduled a session on average
only once every ten sessions. This indicates that
students are at least partly motivated by the
amount of money they have invested for in-person
tutoring.
Which of the following, if true, calls into question
the explanation above?
A.The price per hour was slightly more
expensive for those who bought
individual hours.
B. Many students who missed or
rescheduled sessions did so
although they made a strong verbal
commitment beforehand to be
present.
C. All students must pay a 10% fee for
rescheduling any tutoring session, but
if a student cancels a session entirely,
the entire cost is forfeited.
D. Upon purchase of any tutoring hours,
students are required to immediately
schedule all the purchased hours.
E. Students who try to reschedule
tutoring sessions without enough
notice may not be able to make up
the session in a timely fashion, so that it counts a missed session.
