PROBLEM: Passage: 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. Question: What policy did the Marble Palace introduce? 

SOLUTION: "free entrance" to all potential customers.

PROBLEM: Passage: Paris has a typical Western European oceanic climate (Köppen climate classification: Cfb ) which is affected by the North Atlantic Current. The overall climate throughout the year is mild and moderately wet. Summer days are usually warm and pleasant with average temperatures hovering between 15 and 25 °C (59 and 77 °F), and a fair amount of sunshine. Each year, however, there are a few days where the temperature rises above 32 °C (90 °F). Some years have even witnessed long periods of harsh summer weather, such as the heat wave of 2003 when temperatures exceeded 30 °C (86 °F) for weeks, surged up to 40 °C (104 °F) on some days and seldom cooled down at night. More recently, the average temperature for July 2011 was 17.6 °C (63.7 °F), with an average minimum temperature of 12.9 °C (55.2 °F) and an average maximum temperature of 23.7 °C (74.7 °F). Question: Which current affects Paris' weather?

SOLUTION: North Atlantic Current

PROBLEM: Passage: Some Flemish dialects are so distinct that they might be considered as separate language variants, although the strong significance of language in Belgian politics would prevent the government from classifying them as such. West Flemish in particular has sometimes been considered a distinct variety. Dialect borders of these dialects do not correspond to present political boundaries, but reflect older, medieval divisions. The Brabantian dialect group, for instance, also extends to much of the south of the Netherlands, and so does Limburgish. West Flemish is also spoken in Zeelandic Flanders (part of the Dutch province of Zeeland), and by older people in French Flanders (a small area that borders Belgium). Question: What kind of governmental boundary does dialect distribution transcend, reflecting medieval divisions?

SOLUTION:
political boundaries
