Is the use of 'falsifiable' appropriate in a scientific hypothesis?

• A. Yes
• B. No
• C. Only sometimes
• D. Never

Answer: (A)

Falsifiability is essential for a scientific hypothesis. In science, a hypothesis should make testable predictions—outcomes you could observe that would show the idea to be false. If there exists a possible observation that could disprove it, the hypothesis is falsifiable. This lets experiments challenge ideas and only keep those that survive rigorous testing. It doesn’t mean the idea is false; it means it can be tested. If repeated experiments support it, confidence grows; if a credible test contradicts it, scientists revise or reject it. For example, the claim that a drug cures a disease only in a specific subset of patients predicts measurable results that can be tested in a controlled study; if results show no improvement or a broader failure, the hypothesis is falsified. Conversely, statements that cannot be tested in principle aren’t scientific, because there’s no possible evidence that could prove them wrong. Therefore, using falsifiable language in a scientific hypothesis is appropriate because it signals testability and openness to evidence.
