types of appropriate supporting material for the topic.
I. Low-carbohydrate diets are not well balanced.
II. Low-carbohydrate diets have not been proven to be effective.
III. Low-carbohydrate diets have been proven to be unsafe.
Answer: Specific purpose: at the end of my speech, my audience should believe that
low-carbohydrate diets are harmful.
Central idea: Low-carbohydrate diets are harmful to your health.
Supporting material might include statistics on such things as how many people are
using the diet, or how much money is spent on the diets annually. If statistics can be
found on how many people lose weight, how much, and how long they keep it off, they
would be effective. In order to make the speech more interesting to the audience, the
speaker might find illustrations that consist of people who have stories about the diet, or
maybe a hypothetical illustration of a person trying to stay on the diet. Expert testimony
of medical doctors or medical researchers might be effective to make the arguments
believable. Lay testimony might help make the arguments clear or identifiable for the
audience.

TB_Q11.85 List and explain the six criteria for evaluating a web source.
Answer: The web source must have (1) Accountability: Who is responsible for the
website? The website should be signed and include information on the author’s expertise
and authority. You should also be able to verify the website’s sponsor. (2) Accuracy: Is
the information correct? The website’s author or sponsor should be a credible authority,
and you may be able to verify or refute the information by consulting another resource. In
addition, the website should be free of mechanical errors; sloppiness in that area can
indicate sloppiness in content. (3) Objectivity: Is the website free of bias? Is the purpose
of the sponsor to support an issue? What are the biases of the author? Does he or she
stand to gain from taking a slanted position? The more objective the author and sponsor,
the more credible the information. (4) Date: Is the site current? The website should
include a date of when it was posted and updated. As in other sources, recent data is
usually preferable. (5) Usability: Do the layout and design of the website facilitate its
use? The website should not contain so many complicated graphics that you cannot
download it or use it efficiently. Is there a fee to access the website’s information? (6)
Diversity: Is the site inclusive? Do language and graphics reflect and respect differences
in gender, ethnic, racial, and sexual preference? Is it accessible by people with
disabilities?
