Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. 1. Identify the conclusion - this is what you are trying to strengthen 2. Personalize the argument 3. Look for weaknesses in the argument 4. Arguments that contain analogies or use surveys rely upon the validity of those analogies and surveys. Answer
