Context and question: In New York City in 1846, Alexander Turney Stewart established the "Marble Palace" on Broadway, between Chambers and Reade streets. He offered European retail merchandise at fixed prices on a variety of dry goods, and advertised a policy of providing "free entrance" to all potential customers. Though it was clad in white marble to look like a Renaissance palazzo, the building's cast iron construction permitted large plate glass windows that permitted major seasonal displays, especially in the Christmas shopping season. In 1862, Stewart built a new store on a full city block with eight floors and nineteen departments of dress goods and furnishing materials, carpets, glass and china, toys and sports equipment, ranged around a central glass-covered court. His innovations included buying from manufacturers for cash and in large quantities, keeping his markup small and prices low, truthful presentation of merchandise, the one-price policy (so there was no haggling), simple merchandise returns and cash refund policy, selling for cash and not credit, buyers who searched worldwide for quality merchandise, departmentalization, vertical and horizontal integration, volume sales, and free services for customers such as waiting rooms and free delivery of purchases. His innovations were quickly copied by other department stores.
What selling methods did the Marble Palace use?
Answer: cash and not credit


Question: The War of 1812, the second and last American war against the United Kingdom, was less successful for the U.S. than the Revolution and Northwest Indian War against natives had been, though it ended on a high note for Americans as well. After the taking control of Lake Erie in 1813, the Americans were able to seize parts of western Upper Canada, burn York and defeat Tecumseh, which caused his Indian Confederacy to collapse. Following ending victories in the province of Upper Canada, which dubbed the U.S. Army "Regulars, by God!", British troops were able to capture and burn Washington. The regular army, however, proved they were professional and capable of defeating the British army during the invasions of Plattsburgh and Baltimore, prompting British agreement on the previously rejected terms of a status quo ante bellum. Two weeks after a treaty was signed (but not ratified), Andrew Jackson defeated the British in the Battle of New Orleans and became a national hero. Per the treaty both sides returned to the status quo with no victor.
Is there an answer to this question: In what year did the U.S. take control of Lake Eerie?

Answer: 1813


Question: At the time structures such as Lie algebras and hyperbolic quaternions drew attention to the need to expand algebraic structures beyond the associatively multiplicative class. In a review Alexander Macfarlane wrote: "The main idea of the work is not unification of the several methods, nor generalization of ordinary algebra so as to include them, but rather the comparative study of their several structures." In a separate review, G. B. Mathews wrote, "It possesses a unity of design which is really remarkable, considering the variety of its themes."
Is there an answer to this question: Lie algebras and hypobolic quanternions drew attention to the need for what?
