Tom walked into a classroom ready to write his final exam.On the first page of his exam,there were twenty multiple choice questions that he found eager to answer.Soon enough,he finished all of the questions and began to check his answers.But then,the number of questions and the number of his answers did not add up,and this made Tom very upset.There was no time left for him to redo the exam and he was very concerned about failing his course,so finally decided to cheat in the exam.
