细节理解题。根据最后一段第三句“The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they let Dawson city as quickly as they had come.”可知，Dawson City满是失望的人们，他们没有兴趣定居下来，当听说在Alaska发现了新的金矿时，他们离开了，和他们来的时候一样迅速。可知，人们离开Dawson City去Alaska碰运气了。故选B。
