Correct option is B
A sound theory is expected to be coherent, consistent, and aligned with existing knowledge, unless it offers new insights or reconceptualizes existing theories. A theory that does not conform to previously established knowledge may lack credibility and relevance, and could be seen as an outlier unless it is robust enough to challenge existing paradigms effectively.
- A. A theory should be simple and precise so it can be clearly understood and applied.
- C. A theory must provide means for verification and interpretation of its ideas, making it testable.
- D. A good theory should guide new discoveries and suggest areas where further investigation is needed.
Information Booster:
- Testability and falsifiability are also key characteristics of a sound theory. A theory must be testable through experiments or observations.
- Consistency with existing knowledge helps ensure that a theory is credible, unless it significantly advances or reshapes current understanding.
Additional Knowledge:
- Paradigm shifts occur when new theories offer better explanations of phenomena that previous theories couldn’t fully explain, as seen with Einstein's theory of relativity replacing Newtonian physics for understanding space-time and gravity.
