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

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

Answer: (C)

A hypothesis is a precise, testable statement about how two or more things are related. When a claim comes with substantial evidence and lots of detail, it means the idea has a solid basis and clear predictions that can be checked through observation or experiment. A well-developed hypothesis states what will be measured, under what conditions, and the expected outcome, so data can either support or refute it. For example, you might hypothesize that increasing sunlight will boost plant height, and then design an experiment to compare growth under different light levels. That kind of specific, testable prediction with supporting details is what makes the term a good fit. In contrast, guesses are informal and not structured for testing, estimations are rough approximations, and theories are broad explanations that cover many observations rather than a single testable claim.
