Question

1. marlene makes the argument that everyone she knows is trying the keto diet so it must really work is an example of what?

• ad hominem fallacy
• post hoc fallacy
• ad populum fallacy
• biased language

Explanation:

An ad populum fallacy (also known as appeal to popularity) occurs when an argument claims something is true or good just because many people do it or believe it. Marlene argues the keto diet works because everyone she knows is trying it, which fits this fallacy. Ad hominem attacks a person's character, post hoc assumes causation from sequence, and biased language uses slanted terms—none match here.

Answer:

C. ad populum fallacy
