Notes
Building an argument
- A claim is a debatable position. Reasons and evidence support it; reasoning explains the link.
- A counterclaim is the opposing view; a rebuttal answers it.
- Good evidence is relevant, sufficient and credible.
Appeals and devices
- Ethos (credibility), pathos (emotion), logos (logic and facts); kairos is good timing.
- Devices: rhetorical questions, repetition and anaphora, parallelism, antithesis, loaded language.
Fallacies
- Ad hominem (attack the person), straw man (distort the argument), bandwagon (everyone does it), false dilemma (only two choices).
- Slippery slope (chain of extreme results), hasty generalization (too little evidence), red herring (distraction), circular reasoning (claim proves itself), false authority (non-expert).

Free-response question
Read this original speech excerpt: "Every day, our school throws away 200 pounds of food. Think of the families in our own town who go to bed hungry. As president of the student council, I have met with the cafeteria staff, and they agree a food donation program is possible. Some say it will cost too much, but local food banks have offered to pick up donations for free. Why waste food when we can feed our neighbors?"

(c) Identify the counterclaim and evaluate the rebuttal.
Show the answer and scoring guide
The counterclaim is that the program will cost too much. The rebuttal, that food banks will pick up donations for free, is effective because it directly answers the cost concern with a specific fact, though more detail about other costs would make it stronger.
