Question

you find an online article. the article claims that a new diet can cure all types of cancer. it does not cite any scientific studies. it also does not include expert opinions. why does this article likely lack credibility? because it is written in a tone that sounds too plain and informal because it doesn’t provide scientific evidence or expert opinions because it doesn’t use emotional language to convince readers because it discusses a topic related to health, diets, and cancer

Explanation:

To determine the lack of credibility, we analyze each option:

• The first option's claim about tone (plain/informal) isn't related to credibility for a health - related claim about curing cancer.
• The second option: For a claim as significant as a diet curing all cancers, scientific studies (evidence) and expert opinions are crucial to support its validity. Without these, the article has no reliable basis, so this is a valid reason for lack of credibility.
• The third option: Using emotional language isn't a requirement for credibility; in fact, credible health - related content should rely on evidence, not emotional appeals.
• The fourth option: Discussing a health - related topic (diet and cancer) doesn't make it lack credibility on its own.

Answer:

B. because it doesn't provide scientific evidence or expert opinions
