Answer:
Sequential
Step-by-step explanation:
There are several types of structures that can be used as a basis to organize non-fiction texts. Among these we find sequential, problem-and-solution, cause-and-effect, compare-and-contrast, and descriptive text structures. In this case, Jack London used a sequential text structure in "To Build a Fire." This structure places the actions in the text in the same order in which they need to occur in real life.
