Which of the following is an indicator of a flawed assumption in an argument?

An unsupported premise serves as a clear indicator of a flawed assumption within an argument. When a premise is unsupported, it lacks sufficient evidence or rationale to justify why it should be accepted as true. This undermines the argument's overall validity since a strong argument relies on premises that are not only true but are also backed up by adequate support. If the foundational premises are questionable or completely unsubstantiated, the conclusions drawn from them may not hold, making the argument weak or flawed.

In logical reasoning, identifying unsupported premises is crucial, as they point to gaps in reasoning that can lead to erroneous conclusions. Supporting premises with evidence strengthens the argument and helps ensure that the conclusions are logically sound.
