Read the original excerpt: In the wilderness cabin, sisters Ada and Fern had one compass, one horse, and one letter proving their uncle had stolen the land. Fern wanted to ride for the judge before snow closed the pass; Ada wanted to remain with their feverish aunt. At dawn, Ada saddled the horse while Fern slept. She placed the compass beside Fern's hand and the letter inside her own coat, then rode away from the pass toward the nearest doctor. The judge's road vanished under snow by noon. Which option best locates the climax and interprets its role in the conflict?
