What is the indicator word?

@Arthur-Guerra, happy to help! Political Power (PP) is made the Sufficient Condition and Wealth (W) is the made the Necessary Condition because of the phrase "wealth is the basis of political power." This is diagrammed as: PP -> W. If A is said to be the basis of B, we know that A is required for B, but we do not necessarily know that A is the only thing required for B. In general, A being the "basis" of B is not enough to say that A is sufficient for B. For example, you could say that lettuce is the basis of salad. Therefore, lettuce is required to make a salad, but other things (dressing, croutons, fruit, etc..) may also be required. So, lettuce would be necessary but not sufficient. This would be diagrammed as: S -> L. Does that make sense? Please let us know if you have any additional questions and best of luck with your studies!
