The professor said that students should specialize their major. The reason why he said so is that to learn many different subjects is wasting time and have a bad effect on major subjects.
The writer said that students require to take classes in many different subjects, because taking a wide variety of subjects provides for a better education.
The opinion is seemed to be right, but for example, engineering students may not need literary subjects. Literary students also may not need engineering subjects. That means that students have to study the subjects which students do not need to study. The opinion that students should take the wide variety of subjects leads to wasting time.
To learn wide different subjects has the possibility of destruction of the major subject for students. It takes too much time for students, if they take many courses. As a result, students need to spend less time to study their major subjects. Generally, the major subject is the most important, so students should spend much time for it.
In this way, although there is a merit point by taking a wide variety of subject, spending much time for major subject is better than that.
