"Some freshmen try to fill up their schedule with late classes so they can sleep in. This is a mistake. You should try to take early classes for several reasons. First, they usually have fewer students in them (always a good thing). Second, it will keep you “living responsibly,” going to bed at a decent hour and feeling healthier. Third, having early classes frees up the rest of your day for fun activities, more studying, or working at a job. Early classes are especially valuable in the springtime weather.” The conclusion here is that it is better for college students to sign up for morning classes. Which of these is an argument from the text supporting that conclusion?
