Final answer:
The Lewis and Clark Expedition received gestures of friendship from the Native American tribes they encountered, likely in the form of traditional gifts such as food or handicrafts, although the specific items are not detailed in the provided information.
Step-by-step explanation:
The question relates to the Lewis and Clark Expedition, specifically to the early diplomatic interactions between the expedition team and the Native American tribes they encountered along their journey. When Captains Meriwether Lewis and William Clark and their Corps of Discovery met with the Otoe and Missouri tribes, they tried to establish peaceful relations and demonstrate American power. In response to the expedition's efforts, which included presenting roasted meats and various other gifts, the Native American tribes reciprocated with their own gestures of friendship.
While the provided information does not specify the exact items the Native Americans sent back, it was customary for tribes to exchange gifts as a form of diplomacy. Possible gifts could include food, horses, or handicrafts such as beadwork or pelts, which were considered valuable and symbolic exchanges during this period. The exchange of gifts was an integral part of the diplomatic practices that helped the Lewis and Clark Expedition create initial bonds with the Native American tribes they encountered, setting the stage for future interactions and trade.
