Example Input: Question: Which of the two states that some claim the treaty territory also includes parts of has a larger total area (sq mi.)? Passage:A Dish With One Spoon, also known as One Dish One Spoon, is a law used by indigenous peoples of the Americas since at least 1142 CE to describe an agreement for sharing hunting territory among two or more nations. People are all eating out of the single dish, that is, all hunting in the shared territory. One spoon signifies that all Peoples sharing the territory are expected to limit the game they take to leave enough for others, and for the continued abundance and viability of the hunting grounds into the future. Sometimes the Indigenous language word is rendered in English as bowl or kettle rather than dish. The Dish With One Spoon phrase is also used to denote the treaty or agreement itself. In particular, a treaty made between the Anishinaabe and Haudenosaunee nations at Montréal in 1701, as part of the Great Peace of Montreal is usually called the Dish With One Spoon treaty and its associated wampum belt the Dish With One Spoon wampum. The treaty territory includes part of the current province of Ontario between the Great Lakes and extending east along the north shore of the St. Lawrence River up to the border with the current province of Quebec. Some claim it also includes parts of the current states of New York and Michigan.

Athenaeus made frequent mention of wine's ability to induce hangover and suggested various remedies for it. The poet Eubulus noted that three bowls (kylikes) were the ideal amount of wine to consume. The quantity of three bowls to represent moderation is a recurring theme throughout Greek writing (today, the standard 750 ml bottle contains roughly three to six glasses of wine, depending on serving size).
