How does the author view competing theories about astronomical findings?

• A. They are flawless and widely supported.
• B. The author describes them as flawed and supports an alternative theory with new evidence.
• C. They are the only valid explanations.
• D. They are unexamined and unchallenged.

Answer: (B)

The author evaluates competing astronomical theories by showing they have flaws and then arguing for an alternative that is backed by new evidence. This reflects a scientific approach: question existing explanations, point out their weaknesses, and use fresh observations or data to support a revised view. The emphasis is on critique of the old theories and justification for a different, better-supported explanation.
