Which of the following is a common flaw associated with reasoning in LSAT arguments?

Circular reasoning is when an argument's conclusion is simply rephrased or restated as part of its premises, thereby providing no independent support for the conclusion. This flaw is common in LSAT arguments because it can appear persuasive at first glance, but it ultimately fails to prove the point being made. For instance, if someone argues that "The law should be obeyed because it is illegal to break the law," they are not actually providing a rationale for why the law should be followed; instead, they are restating the conclusion without any supporting evidence.

This reasoning flaw can easily mislead individuals, especially in complex arguments presented in LSAT questions, making it essential to identify and challenge such reasoning in order to assess the validity of the argument critically. Recognizing circular reasoning allows test-takers to better evaluate the strength of evidence provided in an argument.
