Answer:
Explanation:
There could be a lot of possible reasons as to why Hal, Charles, and Mercedes head for the Klondike despite their inexperience. In fact, I would probably say that they headed for the Klondike because of their inexperience. The trio is simply ignorant of the dangers present in nature, and they are ignorant of the necessary supplies that they need and don't need. They are foolish and overconfident. They feel that their desire to get to their destination will somehow overcome any kind of difficulty.
I'm also confident that they head out to the Klondike because they are greedy. If there was no promise of future wealth, I do not think that they would have gone.
I believe that a reader could make a case that the trio is also stubborn. They are warned about their timing and load, but Hal, Mercedes, and Charles do not heed any of that advice.
As for why they were unsuccessful in reaching the Klondike, the easy is answer is that they died. Their deaths could have been avoided had they listened to the advice of the experienced men about how much to load the sled and to not go over the ice that late in the season. Their arrogance and foolishness ultimately got them killed.
