13. Example 1 - Explanation Who -Authority The Nine 8 Planets
This site seems to have a lot of information on the planets. Most of the site seems to be accurate and current. However when you investigate the author a little more you realize that the author is a software engineer. The author is clearly not an expert on the subject of the solar system.

14. Example 2 - Explanation Who -Authority The Solar System Exploration
This site comes directly from NASA, which is a credible source.

16. Example 2 (What - Objectivity)

17. Example 1 - Explanation What - Objectivity Dihydrogen Monoxide
Literally, the term "dihydrogen monoxide" means "two hydrogen, one oxygen", consistent with its molecular formula: the prefix di- in dihydrogen means "two", the prefix mono- in monoxide means "one", and an oxide is a compound that contains one or more oxygen atoms.
The dihydrogen monoxide hoax involves listing negative effects of water under an unfamiliar scientific name, then asking individuals to help control the seemingly dangerous substance. The hoax is designed to illustrate how the lack of scientific knowledge and an exaggerated analysis can lead to misplaced fears. Dihydrogen monoxide, shortened to DHMO, is a scientific name for water that, while technically correct, is almost never employed.

18. Example 2 - Explanation What - Objectivity Neutrogena Skin Care
This site is trying to persuade us to purchase Neutrogena products by telling us we will have “Smoother skin today. Younger-looking skin tomorrow.” The site states that it’s products are Dermatologist Recommended, does this mean all dermatologist recommend Neutrogena and we shouldn’t use any other products? No, all dermatologist do not recommend this product. This site is just trying to sell us a product and the site is not objective.

21. Example 1 - Explanation Where - Accuracy
The True but little known Facts about Women with AIDS, with documentation
At first glance, it is easy to believe the information on this site has a high level of reliability and accuracy because, after all, it is sponsored by an academic institution. However, upon closer inspection, it becomes very clear that this site is nothing but a hoax and the information included is fictional. The author of the web site actually states that the site is a hoax. An uninformed viewer and a non-critical thinker, however, could easily be persuaded to believe the information included on this web site.

22. Example 2 - Explanation Where - Accuracy HIV/AIDS Fact Sheets
While it isn't clearly stated most of the information provided is based on reports, surveys, studies, and research done by the Center for Disease Control (CDC). Since the web site’s purpose is to convey information about HIV/AIDS to a general audience, the research method isn't easily assessable. Many of the Fact Sheets do make general reference to how the stats were gathered or which report the information was taken.
