b$.)$ Hugh has noticed that he has the most energy in the mornings, so he makes sure he accomplishes his easy, enjoyable tasks in the morning and leaves the more challenging ones for the afternoons.

c$.)$ Aaliyah has several important long$-$term projects going on at work. Since she feels stressed out by the competing deadlines, she organizes her days by completing whatever tasks arise in her email that day.
