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. Integer is divisible by 4. Therefore, is even. [a1] (2) If integer is divisible by 4, then is even. Integer is not even. Therefore, is not divisible by 4. [a2] (3) Integer is divisible by 4. Therefore is divisible by 4 or is an odd integer. [a3] (4) Integer is divisible by 4 and integer is divisible by 3. Therefore, is divisible by 4. [a4] (5) If integer is divisible by 4, then is an even integer. is not divisible by 4. Therefore, is not an even integer. [a5] (6) If integer is divisible by 4, then is divisible by 2. If is divisible by 2, then is an even integer. Therefore, is divisible by 4, then is an even integer. [a6] (Hint: It is helpful to write each argument in a symbolic form.)
