Which term best matches the description Full explanations, evidence (assumptions)?

• A. Guesses
• B. Theories
• C. Inductive Reasoning
• D. Known Knowns

Answer: (B)

A theory is the best match when you’re describing something with full explanations supported by evidence and the underlying assumptions. A theory isn’t just a single fact or a guess—it’s a coherent, well-substantiated framework that brings together diverse observations, data, and experiments. It explains how and why things happen, accounts for a range of phenomena, and makes testable predictions that can be checked with new evidence.

That’s why it fits the description of providing full explanations with evidence and the assumptions that underlie the model. By contrast, a guess lacks robust support; inductive reasoning is a method for forming general ideas from specific observations rather than an explanatory framework itself; and known knowns refer to things we’re certain about, not a comprehensive explanatory system.
