What does 'insidious' mean?

  • A. Immediate and obvious
  • B. So gradual as to not become apparent for a long time
  • C. Sudden and severe
  • D. Quick and detectable
Correct Answer: B

Rationale: The correct definition of 'insidious' is 'So gradual as to not become apparent for a long time.' This term describes something that develops slowly and may not be noticed initially. Choice A, 'Immediate and obvious,' is incorrect because 'insidious' implies the opposite of being immediate. Choice C, 'Sudden and severe,' is incorrect because 'insidious' suggests a slow and subtle progression, not sudden. Choice D, 'Quick and detectable,' is incorrect because 'insidious' does not indicate something quick or easily detectable.
