Final answer:
Without additional context from the text being studied, we cannot determine what Prudence tried out for. It is necessary to look back at the story to find the details about Prudence's activities.
Step-by-step explanation:
To accurately determine what Prudence tried out for, additional context from the material you are studying would be needed. Typically, this question would relate to a narrative or story in an English class where Prudence is a character. Without this context, it's impossible to know if Prudence tried out for swimming, basketball, cheerleading, or softball. It's important to carefully read the text where Prudence is mentioned to find clues about her actions. If this question is part of a reading comprehension exercise, look for the paragraph that discusses Prudence's activities or interests for the answer.
