   Professor Telson cares about two things: his students and the environment. Therefore, he has decided to offer students a makeup quiz to help boost their grades from a C to an B. He is giving this option to students in both sections of his course. To save paper, he realizes that he only needs to print the makeup quiz for students who are not taking the course S/NC. He also computed that only students who scored lower than 62 on quiz 1 or lower than 70 on quiz 2 should get the makeup quiz.
   
   Professor Telson has many emails to answer and wants to use programming to help him decide whether he should print a quiz for a given student.
