Problem: Asphalt:

Asphalt/bitumen is typically stored and transported at temperatures around 150 °C (302 °F). Sometimes diesel oil or kerosene are mixed in before shipping to retain liquidity; upon delivery, these lighter materials are separated out of the mixture. This mixture is often called "bitumen feedstock", or BFS. Some dump trucks route the hot engine exhaust through pipes in the dump body to keep the material warm. The backs of tippers carrying asphalt/bitumen, as well as some handling equipment, are also commonly sprayed with a releasing agent before filling to aid release. Diesel oil is no longer used as a release agent due to environmental concerns.

Diesel oil or kerosene is often mixed into what to retain warmth?

Problem: The political reforms of Peter the Great (Пётр Вели́кий, Pyótr Velíkiy) were accompanied by a reform of the alphabet, and achieved their goal of secularization and Westernization. Blocks of specialized vocabulary were adopted from the languages of Western Europe. By 1800, a significant portion of the gentry spoke French daily, and German sometimes. Many Russian novels of the 19th century, e.g. Leo Tolstoy's (Лев Толсто́й) War and Peace, contain entire paragraphs and even pages in French with no translation given, with an assumption that educated readers would not need one.
How many Germans immigrated to France in 1800?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
To understand groups beyond the level of mere symbolic manipulations as above, more structural concepts have to be employed.c[›] There is a conceptual principle underlying all of the following notions: to take advantage of the structure offered by groups (which sets, being "structureless", do not have), constructions related to groups have to be compatible with the group operation. This compatibility manifests itself in the following notions in various ways. For example, groups can be related to each other via functions called group homomorphisms. By the mentioned principle, they are required to respect the group structures in a precise sense. The structure of groups can also be understood by breaking them into pieces called subgroups and quotient groups. The principle of "preserving structures"—a recurring topic in mathematics throughout—is an instance of working in a category, in this case the category of groups.
What concept describes groups that can be related to each other via functions?
A: group homomorphisms


Context and question: 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.
In what year did New Jersey voters pass a referendum approving casino gambling for Atlantic City?
Answer: 1976


Question: The calendar was a refinement to the Julian calendar amounting to a 0.002% correction in the length of the year. The motivation for the reform was to bring the date for the celebration of Easter to the time of the year in which it was celebrated when it was introduced by the early Church. Because the celebration of Easter was tied to the spring equinox, the Roman Catholic Church considered the steady drift in the date of Easter caused by the year being slightly too long to be undesirable. The reform was adopted initially by the Catholic countries of Europe. Protestants and Eastern Orthodox countries continued to use the traditional Julian calendar and adopted the Gregorian reform after a time, for the sake of convenience in international trade. The last European country to adopt the reform was Greece, in 1923.
Is there an answer to this question: What was the percentsge of correction from the Julian calendar to the new Gregorian calendar?

Answer: 0.002%


QUES: Paper is often characterized by weight. In the United States, the weight assigned to a paper is the weight of a ream, 500 sheets, of varying "basic sizes", before the paper is cut into the size it is sold to end customers. For example, a ream of 20 lb, 8.5 in × 11 in (216 mm × 279 mm) paper weighs 5 pounds, because it has been cut from a larger sheet into four pieces. In the United States, printing paper is generally 20 lb, 24 lb, or 32 lb at most. Cover stock is generally 68 lb, and 110 lb or more is considered card stock.

 Paper rated at over 210lb is considered what type of stock?
