A hypothesis must be supported by what?

A hypothesis must be supported by all pertinent facts. In the scientific method, a hypothesis is a proposed explanation made on the basis of limited evidence as a starting point for further investigation. For a hypothesis to be deemed valid, it must align with known facts and data from observations, experiments, and theoretical underpinnings.

All facts pertaining to the investigation contribute to the robustness of the hypothesis, ensuring that it is not only plausible but also grounded in empirical evidence. Supporting a hypothesis with all relevant facts helps to form a strong foundation for further testing and validation, ultimately leading to a better understanding of the subject in question.

The other choices, such as observations and experiments, are indeed critical to the hypothesis testing process, but they alone do not encompass the broader requirement of having support from all relevant facts across various data points. As a result, reliance solely on a subset of facts, theoretical frameworks, or experimental results does not provide the comprehensive backing necessary for a well-supported hypothesis.
