Answer: This shows that Gavin is more interested to read comic books therefore he is more selfish and buys more books
Explanation: Even though Gavin buys three extra books and shares it fairly with his brother then it's not a big problem. As the concept of sharing and the love between siblings can increased up to a certain extent by this activity. i.e, the three additional comic books must be shared between Gavin and his brother to inculcate the values of equality, kindness and love.
