Explanation:

Based on the information provided, Alice has read a total of 10 books. To find out how many books about her favorite subjects she has not read, we need to determine the number of books for each of her favorite subjects and then subtract the ones she has read.

- For Dinosaurs: The bar line extends to the middle of 20 and 30 on the vertical axis, so there are 30 - 20 = 10 books about Dinosaurs.

- For Insects: The bar line extends to the middle of 10 and 20 on the vertical axis, so there are 20 - 10 = 10 books about Insects.

- For Pirates: The bar line extends to 30 on the vertical axis, so there are 30 books about Pirates.

- For Superheroes: The bar line extends to 40 on the vertical axis, so there are 40 books about Superheroes.

Now, let's add up the books for each of Alice's favorite subjects:

10 (Dinosaurs) + 10 (Insects) + 30 (Pirates) + 40 (Superheroes) = 90 books in total about Alice's favorite subjects in her school library.

Since Alice has read 10 of these books, the number of books about her favorite subjects that she has not read is:

90 (total books) - 10 (books she has read) = 80 books.
