What can be subjected to analysis and can be demonstrated as true or false?

The term that can be subjected to analysis and can be demonstrated as true or false is a fact. Facts are statements that can be verified and substantiated through evidence. They are objective realities that hold true at all times regardless of beliefs or interpretations. For example, "Water boils at 100°C at sea level" is a fact that can be tested and confirmed through scientific observation.

In contrast, a theory is a well-substantiated explanation based on a body of evidence but is not something that can be definitively proven as true or false in all circumstances. An assumption is an idea accepted as true without proof, making it inherently subjective and open to challenge. A hypothesis, while testable and able to lead to conclusions, is still a proposed explanation that has yet to be confirmed or denied. Thus, in the context of being demonstrably true or false, fact stands out as the only option fitting that description.
