Answer:
The common theme between the two excerpts is "humanity's helplessness against nature."
Explanation:
Both excerpts show how human beings are fragile and helpless when nature shows its strength. This can be perceived by the fact that the two excerpts show characters that are dominated by doubts, uncertainties and fear in the face of nature's power over them. This power that the human being is not able to control. Nature can tear down and scare even the strongest human, that's what excerpts want to pass on to the reader.
