What is the text structure in to build a fire by jack londojn

Sequential

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.

This would now be an adverb because it’s explaining the action verb. If you were to say “she has taken exercising to a new extremity,” the extremity is explaining the manner the action verb is in, making the most sense. The noun is “she,” the verb is “exercising” so the only option left really is for it to be an adverb.
