You can rely on Mr．Smith to carry out this mission for his judgment is always ______. A. unquestionable B. healthy C. sound D. subtle

The sentence emphasizes Mr. Smith's reliability for the mission, focusing on the quality of his judgment. We need an adjective describing dependable, sensible judgment.

Analysis of options:

A. Unquestionable means "impossible to doubt," but it focuses more on certainty than the inherent quality of judgment.

B. Healthy typically describes physical/mental well-being, not judgment; "healthy judgment" is not a natural collocation.

C. Sound means "sensible, reliable, and based on good reasoning." "Sound judgment" is a standard phrase describing judgment that is trustworthy and practical—exactly what "rely on" implies.

D. Subtle means "delicate or not obvious," which describes nuance, not reliability.

Answer: C

Sound judgment directly explains why Mr. Smith is reliable—his decision-making is sensible and trustworthy, making him the right choice for the mission. What other qualities might complement "sound judgment" in someone you'd trust with important tasks?
