Correct Answer: A

Rationale: The word 'assured' means to have made certain or confident of something. 'Confirmed' is a synonym that aligns with this meaning. Therefore, the correct answer is A, 'Confirmed the truth of.' Choice B, 'Sympathized with,' does not have a similar meaning to 'assured.' Choice C, 'Denied the truth of,' is the opposite in meaning to 'assured.' Choice D, 'Made known to,' does not convey the same sense of certainty as 'assured.'

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.

Correct Answer: B

Rationale: Another word for PRECAUTION is a preventive measure because both terms refer to actions taken in advance to prevent something untoward from happening. They are proactive steps aimed at avoiding potential risks or harm. While a routine procedure and habit may involve general practices, a preventive measure specifically denotes a proactive step taken to avert potential dangers or issues. 'Routine procedure' is incorrect as it does not necessarily imply preventive action. 'Habit' is incorrect as it refers to repeated behaviors rather than proactive steps. 'Safeguard' is incorrect as it generally means protection rather than a proactive preventive action.

Correct Answer: B

Rationale: The correct answer is B: 'Misgivings'. Trepidation is defined as a feeling of fear or anxiety about something that may happen. Choice A ('Fear') is too broad and does not capture the specific sense of unease that trepidation conveys. Choice C ('Confidence') is the opposite of what trepidation represents. Choice D ('Doubt') is related to uncertainty but does not fully encapsulate the sense of fear and anxiety associated with trepidation.
