my answer on this is c. thanks for your help.

The correct answer is D. Preschoolers use private speech because it enables them to communicate new ideas.

To arrive at this answer, we can eliminate options A, B, and C based on what we know about private speech in preschoolers. Private speech refers to the practice of children talking out loud to themselves, even when no one else is around. It is a common behavior observed in young children, particularly during activities such as playing or problem-solving.

Option A, "to influence others," is not a characteristic commonly associated with private speech in preschoolers. They typically engage in private speech to organize their thoughts and guide their actions, rather than trying to persuade or manipulate others.

Option B, "to keep some of their ideas a secret," is also not a valid explanation for preschoolers using private speech. Private speech is not primarily used as a secretive or covert form of communication. Instead, it is a way for children to articulate their thoughts and make them more explicit, even if no one else is listening.

Option C, "because it is more efficient," is not accurate either. While private speech may assist children in problem-solving and self-regulation, it is not necessarily more efficient than other forms of communication.

Option D, "because it enables them to communicate new ideas," is the correct answer. Children often use private speech as a way to express and explore their thoughts and ideas. By talking out loud, they can externalize their internal thinking processes, develop their language skills, and communicate their innovative or novel ideas.

Therefore, the correct answer is D: Preschoolers use private speech because it enables them to communicate new ideas.
