Despite the scientist's meticulous efforts to control all variables, an anomalous result appeared in the final experiment, forcing a re-evaluation of the initial hypothesis. As used in the sentence, what does the word 'anomalous' most closely mean?
✓ Correct Answer: Option C
The context—'despite meticulous efforts' and 'forcing a re-evaluation'—suggests the result was unexpected or out of the ordinary. 'Unusual' best fits this meaning, contrasting with what would be typical or expected.
