Select the meaning of the quoted word in the sentence. The development of the disease was 'insidious'.

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

Rationale: The word 'insidious' means proceeding in a gradual, subtle way but with harmful effects. In the context of the sentence, describing the disease's development as 'insidious' suggests that it was slow and unnoticed, emphasizing its dangerous nature. Therefore, the correct meaning is 'Gradual'. 'Momentous' means of great importance, 'Sudden' means happening quickly without warning, and 'Innocuous' means harmless, which do not align with the intended meaning of 'insidious' in this sentence.
