b the start, middle, and end of the klondike gold rush

c a man named skookum jim mason

d what happened to dawson city after the klondike gold rush ended

Explanation:

To determine the main idea, we analyze each option: Option A compares two gold rushes, but the text likely focuses on Klondike alone. Option C is about a single person, too narrow. Option D focuses on post - rush Dawson City, while a text about the Klondike Gold Rush would likely cover its start, middle, and end (Option B) as a comprehensive overview.

Answer:

B. the start, middle, and end of the Klondike Gold Rush
