The argument:

Diagram, and analyze the following:

“Since the number is either odd or even, it is either true that the number is odd or true that it is even. Therefore, something is true but not certain. Either ‘The number of coins now on the train is odd’ is an example of truth without certainty, or ‘The number of coins now on the train is even’ is. We know that one of those two sentences is an example, although we are not in a position to know which of them it is. Zac was incorrect in claiming that truth implies certainty.”

Please identify what kind of argument is used in the excerpt and diagram it. I have attached an example of what the format is supposed to look like. Thank you!
