It was the last day of the final examination in a large eastern university．On the steps of one building, a group of students were talking about the exam that was going to begin in a few   21 . On their faces was confidence. This was their   22   exam—then on to graduation and jobs.
Some talked of jobs they already had, others talked of jobs they   23   get. With the certainty of four years of college, they felt   24   and able to take control of the world.
The coming exam, they knew, would be a（n） 25  task, as the professor had said they could bring   26  books or notes they wanted, requesting only that they did not   27  each other during the test.
28   they entered the classroom. The professor passed out the papers. And smiles   29 on the students’ faces as they found there were only five questions.
Three hours had passed   30   the professor began to collect papers. The students no longer looked confident. On their faces was a frightened expression. Papers in hand, no one spoke as the professor faced the class.

These questions you could not answer are relatively common in    37     practice.” Then, smiling, he added, “You will all   38  this course, but remember—even though you are now college graduates, your education had just   39   .”
The years have weakened the name of the professor, but not the  40   he taught.
