The weather is too hot; I need some water to … my thirst.

Step 1: Analyze the question The sentence is: "The weather is too hot; I need some water to ____ my thirst." We need the verb that collocates correctly with "thirst."

Step 2: Explain the concept (collocation) In English, some words naturally go together. This is called collocation. The word we need is the one that means "to satisfy or put an end to" a thirst.

Step 3: Test each option

• A. wet: This means to make something damp. You can wet your lips, but you do not "wet your thirst."
• B. quench: This means to satisfy a thirst or to put out a fire. "Quench your thirst" is a standard English phrase.
• C. cool: This relates to temperature. You can cool your body or a drink, but you do not "cool thirst."
• D. soak: This means to immerse something in liquid. It does not collocate with thirst.

Step 4: Answer The correct word is quench, which is option B.

Complete sentence: "The weather is too hot; I need some water to quench my thirst."
