Which of the following statements is TRUE according to the passage?

As to the relationship between an author and a professor, I had long thought that writing was more important than teaching. And as a student, I always looked for professors who were writing something. I suspected that they were more alert and lively. It turned out in experience though that a couple of men who wrote very little were in fact my best teachers, and one famous writer was the worst teacher I ever had. My friend, Fr. Robert Spitzer, at Gonzaga University, himself a man of blazing intellect and eloquence, once remarked to me that teaching is more important than writing. Chances are that you will actually teach more students than will ever read what you write. This was a sobering thought, but as I thought about it, it is really true. But writing enables you to get nut of the classroom into minds, somewhere, you never know where.
    In recent years, I will have had maybe one hundred and fifty students, more or less, a semester in two classes. They are always young men and women you would like to know better. You have them for the briefest period and they are gone. I try to know each of them by name, talk to them in class, converse with them.
    I usually have forty classes a semester. I am there to assign something for the students to read. In the beginning, the students are subdued, skeptical perhaps. But one day, midway through the semester, you will look at the class. Suddenly a young man or woman in the back row, who seemed at first clueless, is sitting there with eyes wide open. You know that suddenly the student has woken up in that sense for which the classical university was supposed to exist for its students, to let them know that there was light. They were supposed to, made to, see it.
