Document Summary
Review of concepts questions for unit 1 (slide 65: you are not going to get photos in your tests. Video: dog knows a 1000 words has a variety of toys and is asked to bring back one that she does not know. You know the name of everything else, so you"ll bring the one you don"t know: kind of like process of elimination. The dog is ruling out what she is knows through deduction. Reminder: remember in unit 1 (1) we learned that for the sake of clarity and brevity, they represent statements through symbols such as a,b,c. p,q,r. Disjunction has the form of either p or q. It is always going to have the form of p or q: this argument form is always going to be valid. Practice questions: the first question is the exact type of question you are going to see on your test, e. g. find the disjunctive syllogism.
