Answer:
That a long time has passed since the end of the previous chapter.
Step-by-step explanation:
This question refers to chapters 12 and 13 of the book Hatchet. In this book, Brian Robeson is a teenager who has to learn how to survive in the wilderness after the plane he was travelling in crashed into a lake in the forest. The only thing that Brian has is his hatchet. In chapter 12, we learn that Brian is trying to catch fish. In fact, he is able to fashion a bow and arrow to do so. However, in chapter 13, we learn that he is already sick of fish. This means that he was able to catch them and has been eating them for a while. Therefore, we can assume that a long time has passed between these two chapters.
