(Answer аny fоur questiоns—eаch cоrrect аnswer is worth 3 points. You will earn 1 bonus point for each additional correct answer beyond the required four.) Consider the arguments below. If the argument is valid, identify its logical form. Otherwise, indicate whether the converse or inverse error is made. (1) If integer is divisible by 4, then is even. is not an even integer. Therefore, is not divisible by 4. [a1] (2) If integer is divisible by 4, then is even. Integer is divisible by 4. Therefore, is an even integer.[a2] (3) If integer is divisible by 4, then is even. Integer is not divisible by 4. Therefore, is not an even integer. [a3] (4) If integer is divisible by 4, then is divisible by 2. If integer is divisible by 2, then is even. Therefore, if is divisible by 4, then is even. [a4] (5) Integer is divisible by 4. Therefore, is divisible by 4 or is an odd integer. [a5] (6) Integer is divisible by 2 or is odd. is not odd. Therefore, is divisible by 2. [a6] (Hint: It is helpful to write each argument in a symbolic form.)

If the argument is valid, identify its logical form. Otherwise, indicate whether the converse or inverse error is made. (1) This graph can be colored with three colors. Therefore, this graph can be colored with three colors or it can be colored with four colors. [a1] (2) If this graph can be colored with three colors, then it can be colored with four colors. The graph cannot be colored with four colors. Therefore, the graph cannot be colored with three colors. [a2] (3) If this graph can be colored with three colors, then it can be colored with four colors. The graph cannot be colored with three colors. Therefore, the graph cannot be colored with four colors. [a3] (4) The real number is greater than 2 or is less than 4. is not greater than 2. Therefore, is less than 4. [a4] (5) The real number is greater than 2 and is greater than 5. Therefore, is greater than 5. [a5] (6) If the real number is greater than 2, then is positive. If is positive, then exists. Therefore, if is greater than 2, then exists. [a6] (Hint: It is helpful to write each argument in a symbolic form.)
