Problem: In the early 21st century, the population of Paris began to increase slowly again, as more young people moved into the city. It reached 2.25 million in 2011. In March 2001, Bertrand Delanoë became the first socialist mayor of Paris. In 2007, in an effort to reduce car traffic in the city, he introduced the Vélib', a system which rents bicycles for the use of local residents and visitors. Bertrand Delanoë also transformed a section of the highway along the left bank of the Seine into an urban promenade and park, the Promenade des Berges de la Seine, which he inaugurated in June 2013.

Problem: When he became First Consul and later Emperor, Napoleon eschewed his general's uniform and habitually wore the simple green colonel uniform (non-Hussar) of a colonel of the Chasseur à Cheval of the Imperial Guard, the regiment that often served as his personal escort, with a large bicorne. He also habitually wore (usually on Sundays) the blue uniform of a colonel of the Imperial Guard Foot Grenadiers (blue with white facings and red cuffs). He also wore his Légion d'honneur star, medal and ribbon, and the Order of the Iron Crown decorations, white French-style culottes and white stockings. This was in contrast to the gorgeous and complex uniforms with many decorations of his marshals and those around him.
What color stockings did Napoleon usually wear?
The answer is the following: white

Problem: Beer was spread through Europe by Germanic and Celtic tribes as far back as 3000 BC, and it was mainly brewed on a domestic scale. The product that the early Europeans drank might not be recognised as beer by most people today. Alongside the basic starch source, the early European beers might contain fruits, honey, numerous types of plants, spices and other substances such as narcotic herbs. What they did not contain was hops, as that was a later addition, first mentioned in Europe around 822 by a Carolingian Abbot and again in 1067 by Abbess Hildegard of Bingen.
Who was believed to have added hops to beer in 1067?
The answer is the following: Abbess Hildegard

Problem: Season six premiered with the series' highest-rated debut episode and a few of its succeeding episodes rank among the most watched episodes of American Idol. During this time, many television executives begun to regard the show as a programming force unlike any seen before, as its consistent dominance of up to two hours two or three nights a week exceeded the 30- or 60-minute reach of previous hits such as NBC's The Cosby Show. The show was dubbed "the Death Star", and competing networks often rearranged their schedules in order to minimize losses. However, season six also showed a steady decline in viewership over the course of the season. The season finale saw a drop in ratings of 16% from the previous year. Season six was the first season wherein the average results show rated higher than the competition stages (unlike in the previous seasons), and became the second highest-rated of the series after the preceding season.
Which season premiere was the most watched of all seasons?
The answer is the following:
Season six
