Issue
There are wording mistakes in the exercise descriptions for Lessons 16 (AVG) and 17 (MAX/MIN) that make the questions confusing.
Lesson 15 currently says: "Can you find the total num_books_read made by this family?"
The phrase "books made by this family" is grammatically incorrect. It should refer to books that were read, not made.
Lesson 16 currently says: "Can you find the highest num_books_read that a family member makes?"
Similarly, "makes" should be "reads."
Suggested fixes
Lesson 15
Replace: "Can you find the total num_books_read made by this family?" with "Can you find the total number of books read by this family?"
Lesson 16
Replace: "Can you find the highest num_books_read that a family member makes?" with "Can you find the highest number of books read by a family member?"
