Is It Real Online News? Or Just Advertising?

In April 2011, the Federal Trade Commission warned the public about fake online news sites promoting an acai berry "weight-loss" product.
On a typical fake “news” site, a story described an investigation in which a reporter used the product for several weeks, with “dramatic” results. The site looked real, but it was actually an advertisement. Everything was fake: there was no reporter, no news organization, and no investigation. The only real things were the links to a sales site that appeared in the story and elsewhere on the Web page.
Which of the following do you think may be an indication that a “news” site is fake? (Check all that apply.)
Wrong—Including a quote from an independent expert does not indicate a site is fake.
Wrong—Discussing the limitations of research does not indicate a site is fake.
Right! All of the checked signs are warnings that a site may be fake.
