What does the two-source rule require?

• A. Verify key facts with at least two independent sources to reduce errors and bias and increase credibility.
• B. Rely on a single official document.
• C. Use anonymous tips as the sole basis.
• D. Only quote one expert.

Answer: (A)

Two-source rule means you verify key facts by obtaining confirmation from at least two independent sources. This approach reduces the chance of errors, misinformation, and bias, and it boosts credibility because the information is corroborated by more than one source. It emphasizes independence—sources should be separate and not simply echo the same line.

This is why the other options aren’t as solid: relying on a single official document can miss context or bias, anonymous tips aren’t verifiable on their own, and quoting only one expert lacks corroboration. When two independent sources agree, you have stronger confidence in the accuracy of the information. If they don’t, you investigate further or seek additional corroboration before reporting.
