Which term best matches the description Substantial evidence, lots of detail?

• A. Guesses
• B. Estimations
• C. Theories
• D. Hypothesis

Answer: (D)

This question tests how you distinguish a well-supported scientific explanation from guesses and rough calculations. When there’s substantial evidence and a detailed account that ties many observations and experiments together, that points to a theory. In science, a theory is a broad, robust explanation that has withstood repeated testing and can explain and predict a wide range of phenomena. It isn’t just a single guess or a rough estimate; it’s a comprehensive model built from extensive evidence and detailed reasoning. A hypothesis is a proposed explanation that guides experiments and is tested to see if it holds up, without the breadth of evidence and detail a theory has. So, with substantial evidence and lots of detail, the best fit is that a theory describes the situation.
