A fact is defined as a situation that has been proven to be true, based on objective evidence and verifiable information. This means that a fact can be confirmed through observation, measurement, or other forms of validation. In contrast to personal beliefs or interpretations, a fact is grounded in reality and does not change depending on individual perspectives.

The other options represent different concepts that do not align with the definition of a fact. A hypothesis is something proposed for investigation and lacks confirmation, making it speculative rather than factual. Personal experiences can lead to subjective interpretations that may not universally be accepted as true. An assumption based on observation can be influenced by biases and may not be supported by definitive evidence, thus not qualifying as a fact. Therefore, only the situation described in the first choice meets the criteria for what constitutes a fact.
