Have you ever seen a TV program or movie in which a detective gathers bits and pieces of evidence, and then tries to organize the clues into a logical framework to reveal a pattern that will solve the mystery? One way to organize facts is to place them on a grid. Then, by using deductive reasoning, the detective can find the patterns that lead to a solution. In this lab, you get to be the detective and solve some grid logic puzzles. Background: In school today, there was a meeting of all the Freshman, Sophomore, and Junior boys. Each class was instructed to sit in a specific section of the room. After the assembly, Mr. Holmes, the Campus Director, found three notebooks left behind by careless students. None of the notebooks had its owner’s name in it, so Mr. Holmes was forced to use some deductive reasoning to figure out the owners. Based on where he found the notebooks, he could tell that a notebook was lost from one member of each class. He asked a few teachers if they knew who owned the notebooks and they were able to provide him with some sketchy information. Read the facts below and use the grids to solve the mystery of the notebook owners. Whenever you find a piece of information that applies to a notebook or its owner, mark a circle in the appropriate box in a grid below. If you find a piece of information that definitely rules out a particular notebook belonging to a student, mark an X in the box. Now, let’s look at the facts. Facts: 1 – One of the owners was Pedro, who did not lose the blue notebook and is younger than Larry. 2 – A Junior lost the green notebook. 3 – The student who lost the red notebook was not Connor. 4 – Connor is a Sophomore. What do we know? According to the facts, the three students were Connor (C), Pedro (P), and Larry (L). The color of each notebook was red (R), blue (B), and green (G). Pedro did not lose the blue notebook (1), so we can place an X in the square that corresponds with Pedro and blue. We also know that Pedro is younger than Larry (1), so he could not be the Junior.
