Final answer:
Without specific text, it can't be determined which quality is most important for surviving in the North. However, resourcefulness is a vital survival trait and is crucial in gathering-hunting societies which rely on natural resources.
Step-by-step explanation:
The question does not provide enough context for me to accurately determine which quality the text argues is most important for surviving in the North. However, historically and in literature, resourcefulness is often highlighted as a vital survival trait in harsh environments. In scenarios such as the survival in grassland environments mentioned in the provided information, gathering-hunting societies needed to be resourceful by using the natural resources readily available in their environment. They would gather food like fruits and nuts, as well as hunt and trap animals to make a living. Therefore, given the importance of effectively using one's surroundings, resourcefulness can be argued as a critical quality for survival in challenging conditions.
