What is a synonym for erroneous or false?

  1. Fallacious

  2. Conciliatory

  3. Extol

  4. Ail

The correct answer is: Fallacious

The choice of "fallacious" as a synonym for "erroneous" or "false" is accurate due to its definition. "Fallacious" describes something that is based on a mistaken belief or contains error, typically involving a misleading or unsound argument. For instance, a fallacious argument often derives its persuasive power from false premises or flawed reasoning, rendering the conclusion invalid or untrue. In contrast, the other options have different meanings that do not align with the concept of being erroneous or false. "Conciliatory" refers to actions intended to placate or pacify, which does not pertain to inaccuracies. "Extol" means to praise highly, which reflects positive affirmation rather than an incorrect assertion. Lastly, "ail" means to suffer or be troubled by something, which is unrelated to the ideas of truth or error. Therefore, "fallacious" is the appropriate synonym in this context.
