Identify the conclusion the author probably intends readers to draw,
and put the argument into standard form. Evaluate the argument using three (3) of the methods you learned in Unit 3 (that is, identifying the form of the argument, thinking of another argument of the same form with obviously true premises and an obviously false conclusion, thinking of circumstances in which the premises of the argument could be true and the conclusion false, questioning the premises, and discussing whether the language used in the argument is unacceptably vague or ambiguous). Be sure to indicate how you are abbreviating the terms involved where appropriate.
