To whom does Alex intend to deliver the water sample for testing?

• A. His dad
• B. A private lab
• C. The city water department
• D. His teacher

Answer: (A)

Figuring out who receives the water sample relies on the story’s setting and relationships. The scenario describes a personal, home-focused context, so the most natural choice is that Alex intends to deliver the sample to a family member who can handle or supervise the testing. His dad fits this role because a parent is typically the one to oversee home projects or errands in a family setting. A private lab would suggest formal, paid testing rather than a quick home task; the city water department handles municipal water systems, not individual household samples; and a teacher would only be involved if this were a school assignment, which isn’t indicated here. So the intended recipient is his dad.
