The Mountains<br>The explorers were hiking. They were trying to pass through a mountain range. They spent three days trying to cross. They finally found themselves walking downhill again. They had reached the other side!
The entire hike lasted more than a week.
We know that this part of the hike lasted 3 days, but we don't know what other parts of the hike there were, or how long they took, so we can't really say for sure whether or not it lasted longer than a week. It's difficult because the text mentions 3 days, which it knows is less than a week.
