Understanding Logical Fallacies Quiz

What is the definition of a "circular reasoning" fallacy?

• A fallacy where an argument is made by attacking the character of the opponent.

• A fallacy where argument is made by simply restating the original claim.

• A fallacy where an argument is made by misrepresenting an opponent's position.

• A fallacy where an argument is made by appealing to the popularity of a claim.

Answer explanation

Circular reasoning is a fallacy where the argument simply restates the original claim without providing any evidence or support. This makes the reasoning circular, as it does not advance the argument logically.
