Abel gave me a hand and cut my grass.

• A. He watered the plants.
• B. He mowed the lawn.
• C. He helped me.
• D. He cooked dinner.

Answer: (C)

Understanding idioms and context: "gave me a hand" is a common expression meaning to help someone. In the sentence, Abel did two things: he helped me and he cut my grass. The best match is the phrase that says he helped me, because that directly reflects the meaning of the expression "gave me a hand." The other options point to actions not described by that part of the sentence (watering plants, cooking dinner) or focus only on the grass-cutting part, which isn’t the focus of the idiom. So the intended meaning is that he helped me.
