ANS:This
passage contains an argument. The issue is whether the students exercising before
school was the cause of the high school students in a study at the University of Manitoba
doing better in their early morning math class. The conclusion is that the students exercising
before school was the cause of the high school students in a study at the University of
Manitoba doing better in their early morning math class. The first premise is that students in a
study at the University of Manitoba who exercised before school did better in their early
morning math class. The second premise is that of the three groups of students in the study at
the University of Manitoba, only the students who exercised before math class showed
improvement.
This argument is an inductive causal argument.

 Psychologists at the University of Manitoba performed an experiment in which high school
students who exercised before school did better in their early morning math class.  The
exercise was most likely the cause of the improvement in math, given that  of the three
groups of students in the study, only the students who exercised before math class showed
improvement.
