The laughter … his face for a moment.

Analyze the question: We need a verb that fits "The laughter ___ his face for a moment." It describes what laughter does to a face briefly.

Explain the concept: This tests vocabulary in context (word meaning and collocation). Let's check each verb:

• Remade: means made again or rebuilt. A face can't be "remade" by laughter, and it doesn't fit the sense of a brief change.
• Improved: means made better. It suggests a lasting change and is an unnatural fit with "for a moment."
• Controlled: means held in check. Laughter doesn't control a face, so the meaning is wrong.
• Animated: means brought to life, made lively or full of energy. Laughter makes a face lively and expressive, and the effect is temporary, which matches "for a moment."

Solution: "The laughter animated his face for a moment" means his face became lively and expressive for a short time because of the laughter. This is the most natural and logical meaning.

Answer: D. Animated.

Tip: In "best complete the gap" questions, test each option in the sentence and ask, "Does it fit the meaning and sound natural?" Also watch for time clues like "for a moment," which point to a temporary effect. "Animated" is often used for faces, voices, and conversations to mean lively.
