Problem: Nintendo Entertainment System:

Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.

Why did the companies circumvent the authentication system?

A: refusing to pay the licensing fee or having been rejected by Nintendo

Problem: In 1841, Leon Escudier wrote of a recital given by Chopin that year, "One may say that Chopin is the creator of a school of piano and a school of composition. In truth, nothing equals the lightness, the sweetness with which the composer preludes on the piano; moreover nothing may be compared to his works full of originality, distinction and grace." Chopin refused to conform to a standard method of playing and believed that there was no set technique for playing well. His style was based extensively on his use of very independent finger technique. In his Projet de methode he wrote: "Everything is a matter of knowing good fingering ... we need no less to use the rest of the hand, the wrist, the forearm and the upper arm." He further stated: "One needs only to study a certain position of the hand in relation to the keys to obtain with ease the most beautiful quality of sound, to know how to play short notes and long notes, and [to attain] unlimited dexterity." The consequences of this approach to technique in Chopin's music include the frequent use of the entire range of the keyboard, passages in double octaves and other chord groupings, swiftly repeated notes, the use of grace notes, and the use of contrasting rhythms (four against three, for example) between the hands.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A team led by Enrico Fermi in 1934 observed that bombarding uranium with neutrons produces the emission of beta rays (electrons or positrons from the elements produced; see beta particle). The fission products were at first mistaken for new elements of atomic numbers 93 and 94, which the Dean of the Faculty of Rome, Orso Mario Corbino, christened ausonium and hesperium, respectively. The experiments leading to the discovery of uranium's ability to fission (break apart) into lighter elements and release binding energy were conducted by Otto Hahn and Fritz Strassmann in Hahn's laboratory in Berlin. Lise Meitner and her nephew, the physicist Otto Robert Frisch, published the physical explanation in February 1939 and named the process "nuclear fission". Soon after, Fermi hypothesized that the fission of uranium might release enough neutrons to sustain a fission reaction. Confirmation of this hypothesis came in 1939, and later work found that on average about 2.5 neutrons are released by each fission of the rare uranium isotope uranium-235. Further work found that the far more common uranium-238 isotope can be transmuted into plutonium, which, like uranium-235, is also fissile by thermal neutrons. These discoveries led numerous countries to begin working on the development of nuclear weapons and nuclear power.
When was it observed that bombarding uranium with neutrons results in gamma ray emission?
A: unanswerable

Context and question: Chinese men entered the United States as laborers, primarily on the West Coast and in western territories. Following the Reconstruction era, as blacks set up independent farms, white planters imported Chinese laborers to satisfy their need for labor. In 1882, the Chinese Exclusion Act was passed, and Chinese workers who chose to stay in the U.S. were unable to have their wives join them. In the South, some Chinese married into the black and mulatto communities, as generally discrimination meant they did not take white spouses. They rapidly left working as laborers, and set up groceries in small towns throughout the South. They worked to get their children educated and socially mobile.
What did Chinese laborers do after they left that line of work?
Answer: set up groceries in small towns throughout the South

Question: Fans of professional wrestling have their own subculture, comparable to those of science fiction, video games, or comic books (in some cases, the "fandoms" overlap; in recent years, some professional wrestlers, particularly those who nurture an anti-establishment rebel persona, such as CM Punk, have made guest appearances at comic book conventions). Those who are interested in the backstage occurrences, future storylines, and reasonings behind company decisions read newsletters written by journalists with inside ties to the wrestling industry. These "rags" or "dirt sheets" have expanded into the Internet, where their information can be dispensed on an up-to-the-minute basis. Some have expanded into radio shows.
Is there an answer to this question: What do the fans have?

Answer: their own subculture

QUES: In 1970, President Nasser died and was succeeded by Anwar Sadat. Sadat switched Egypt's Cold War allegiance from the Soviet Union to the United States, expelling Soviet advisors in 1972. He launched the Infitah economic reform policy, while clamping down on religious and secular opposition. In 1973, Egypt, along with Syria, launched the October War, a surprise attack to regain part of the Sinai territory Israel had captured 6 years earlier. it presented Sadat with a victory that allowed him to regain the Sinai later in return for peace with Israel.

What did Sadat exchange for the remainder of Sinai?
What is the answer?
ANS:
peace with Israel
