At the start of Lilly's Friday afternoon biology class, the instructor, Dr. Forrester, asked everyone to pass their lab reports to the front of the room. She suddenly realized that she had forgotten all about the assignment. After class, she approached Dr. Forrester and asked if she could hand her lab report in on Monday instead. He explained that he was obligated to hold her to the same deadline as everyone else, unless there was a valid reason to make an exception. Lilly said, "Please, you have to let me finish it this weekend and hand it in on Monday! If you don't, I may not pass the course, and if that happens, I'll lose my financial aid and have to drop out of college!" Which type of flawed logic did Lilly use in her plea?
