Explanation:

For the first question, without further context about Sarah's explanation, we can only analyze the options. Demonstrating plant - growth techniques, showing how to water plants, and discussing plant types are more specific than showing how photosynthesis works which is a fundamental and broad - scope plant - related concept that could be a likely purpose of an explanation to classmates.
