Cardinal bishops do not have any powers of governnace over the suburibicarian see since when?
The answer is the following: 1962

Problem: Although an alloy is technically an impure metal, when referring to alloys, the term "impurities" usually denotes those elements which are not desired. These impurities are often found in the base metals or the solutes, but they may also be introduced during the alloying process. For instance, sulfur is a common impurity in steel. Sulfur combines readily with iron to form iron sulfide, which is very brittle, creating weak spots in the steel. Lithium, sodium and calcium are common impurities in aluminium alloys, which can have adverse effects on the structural integrity of castings. Conversely, otherwise pure-metals that simply contain unwanted impurities are often called "impure metals" and are not usually referred to as alloys. Oxygen, present in the air, readily combines with most metals to form metal oxides; especially at higher temperatures encountered during alloying. Great care is often taken during the alloying process to remove excess impurities, using fluxes, chemical additives, or other methods of extractive metallurgy.
What are the three common impurities in aluminum alloys?
The answer is the following: Lithium, sodium and calcium

Problem: In an effort at revitalizing the city, New Jersey voters in 1976 passed a referendum, approving casino gambling for Atlantic City; this came after a 1974 referendum on legalized gambling failed to pass. Immediately after the legislation passed, the owners of the Chalfonte-Haddon Hall Hotel began converting it into the Resorts International. It was the first legal casino in the eastern United States when it opened on May 26, 1978. Other casinos were soon constructed along the Boardwalk and, later, in the marina district for a total of eleven today. The introduction of gambling did not, however, quickly eliminate many of the urban problems that plagued Atlantic City. Many people have suggested that it only served to exacerbate those problems, as attested to by the stark contrast between tourism intensive areas and the adjacent impoverished working-class neighborhoods. In addition, Atlantic City has been less popular than Las Vegas, as a gambling city in the United States. Donald Trump helped bring big name boxing bouts to the city to attract customers to his casinos. The boxer Mike Tyson had most of his fights in Atlantic City in the 1980s, which helped Atlantic City achieve nationwide attention as a gambling resort. Numerous highrise condominiums were built for use as permanent residences or second homes. By end of the decade it was one of the most popular tourist destinations in the United States.
The owners of the Chalfonte-Haddon Hall Hotel converted it into what?
The answer is the following: Resorts International

Problem: Between 1853 and 1870, the Emperor Napoleon III and the city's first director of parks and gardens, Jean-Charles Alphand, created the Bois de Boulogne, the Bois de Vincennes, Parc Montsouris and the Parc des Buttes-Chaumont, located at the four points of the compass around the city, as well as many smaller parks, squares and gardens in the Paris' quarters. Since 1977, the city has created 166 new parks, most notably the Parc de la Villette (1987), Parc André Citroën (1992), and Parc de Bercy (1997). One of the newest parks, the Promenade des Berges de la Seine (2013), built on a former highway on the Left Bank of the Seine between the Pont de l'Alma and the Musée d'Orsay, has floating gardens and gives a view of the city's landmarks.
Who was Paris' first director of parks and gardens?
The answer is the following:
Jean-Charles Alphand
