Final answer:
The similarity between Osborn and Nace as mountain climbers isn't explicitly provided in the question or the passages given. More context is needed to accurately identify a common trait between them.
Step-by-step explanation:
Osborn and Nace, as mountain climbers, differ in many aspects of their approach to climbing, yet there is not enough information provided to discern in what explicit manner they are similar. One might speculate based on common traits found among mountain climbers, such as a shared passion for adventure or respect for nature, might be areas where they agree.
However, to answer accurately, we would need more context or a direct comparison pointing out a specific similarity. Regarding the passages provided, it appears they describe different scenarios involving climbing or outdoors expertise.
One passage talks about a climbing scenario with Venters and the significance of the nicks on the rocks, demonstrating attention to detail and a historical sense of place, while another passage mentions the utility of skills in a team setting, exemplified by Jethro having an absolute advantage in various camping-related activities. In the context of climbing, both passages suggest a degree of skill and strategy, yet they do not directly address the comparison between Osborn and Nace.
