Question 1. You are on the same island that we encountered in lecture that contains only two types of people: knights that always tell the truth and knaves that always lie. Six natives, A, B, C, D, E, and F approach you and each says the following: i. Person A: "None of us are knights." ii. Person B: "At last three of us are knights." iii. Person C: At most three of us are knights." iv. Person D: Exactly five of us are knights." v. Person E: "Exactly two of us are knights." vi. Person F: "Exactly one of us is a knight." How many knights are there? Argue as we did in class/in Example 2.3.14 in the text book. Make sure to justify all of your steps
