The development of the disease was 'insidious'. What does insidious mean in this context?

  • A. Gradual
  • B. Momentous
  • C. Sudden
  • D. Innocuous
Correct Answer: A

Rationale: In this context, 'insidious' means progressing slowly but having harmful effects. This matches the meaning of 'gradual,' making it the correct answer. 'Momentous' means significant or important, which is not the meaning conveyed by 'insidious.' 'Sudden' means abrupt or unexpected, opposite to the slow progression indicated by 'insidious.' 'Innocuous' means harmless, which is the opposite of the harmful effects associated with an insidious disease.
