(Pleаse chооse аnd аnswer ANY 4 questiоns out of 6; 2.75 points for each. For the other 2 questions, you will receive 1.5 bonus points for each correct answer.) Consider the arguments below. If the argument is valid, identify its logical form. Otherwise, indicate whether the converse or inverse error is made. (1) The real number is greater than 2 and is greater than 8. Therefore, is greater than 8. [a1] (2) If this graph can be colored with three colors, then it can be colored with four colors. The graph can be colored with four colors. Therefore, the graph can 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 can be colored with three colors. Therefore, the graph can be colored with four colors. [a3] (4) The real number is greater than 4 or is less than 2. is less than 2. Therefore, is greater than 4. [a4] (5) If the real number is greater than 2, then is positive. If is positive, then exists. Therefore, if is greater than 2, then exists. [a5] (6) is a rational number. is positive. Therefore, is a positive rational number. [a6] (Hint: It is helpful to write each argument in a symbolic form.)
