caption: The image shows a book with a picture of a man jumping in the air, surrounded by text and numbers. The man is wearing a bright yellow shirt and blue shorts, and has a determined expression on his face. He is in mid-air, with his arms outstretched and his legs bent at the knees. The text on the book is written in a bold font and the numbers are in a smaller font. The background of the image is a bright blue sky with white clouds.
