People who talk and sing to plants are not crazy, according to Mr. Braymar, an agriculture expert(农业专家). "In fact, singing and talking to plants makes them grow better," says Braymar. The reason is quite simple -- when we sing or talk to plants, we breathe out carbon dioxide (二氧化碳) which plants need to live and grow. Plants take in the carbon dioxide during the sunlight hours and produce oxygen(氧气) which people need to live. Singing and talking is effective, however, only during the daytime.

1. Plants need ________ in the daytime.

A. carbon B. dioxide C. carbon dioxide D. oxygen
