Hi,
In the below sentence (marked right), there shouldn't be a comma after 'following direction's right?
•WRONG: Since the teacher introduced the classroom
reward system, students have begun paying closer attention, completing
homework, following directions, and have stopped causing disruptions during
lessons.
–Here, the list of “begun” includes only 3
things… the fourth item is “stopped”… so the word “and” has to come before the
last element in the string… and to make “begun” and “stopped” parallel, we need
one more “and”.
•RIGHT: Since the teacher introduced the classroom
reward system, students have begun paying closer attention, completing
homework, AND following directions, and
have stopped causing disruptions during lessons.
