А можно по русски написать

Answer 2

I'm sorry, but I don't have access to specific books or their contents, including the "Activity Book on page 18" that you mentioned. Therefore, I can't provide you with details about how sounds were made on that page.

However, if you can describe the context or provide more information about what you're looking for, I'd be happy to try and help you with that. Whether it's about making sounds in general, the history of sound production, or any other related topic, feel free to ask, and I'll do my best to assist you.
