Problem: To Kill a Mockingbird:

In 2001, Lee was inducted into the Alabama Academy of Honor. In the same year, Chicago mayor Richard M. Daley initiated a reading program throughout the city's libraries, and chose his favorite book, To Kill a Mockingbird, as the first title of the One City, One Book program. Lee declared that "there is no greater honor the novel could receive". By 2004, the novel had been chosen by 25 communities for variations of the citywide reading program, more than any other novel. David Kipen of the National Endowment of the Arts, who supervised The Big Read, states "people just seem to connect with it. It dredges up things in their own lives, their interactions across racial lines, legal encounters, and childhood. It's just this skeleton key to so many different parts of people's lives, and they cherish it."

Which year was Lee awarded an induction into the Alabama Academy of Honor?

A: 2001

Problem: The first vertebrates appeared over 500 million years ago (Mya), during the Cambrian period, and may have resembled the modern hagfish in form. Sharks appeared about 450 Mya, amphibians about 400 Mya, reptiles about 350 Mya, and mammals about 200 Mya. Each species has an equally long evolutionary history, but the brains of modern hagfishes, lampreys, sharks, amphibians, reptiles, and mammals show a gradient of size and complexity that roughly follows the evolutionary sequence. All of these brains contain the same set of basic anatomical components, but many are rudimentary in the hagfish, whereas in mammals the foremost part (the telencephalon) is greatly elaborated and expanded.
At how many mya did mammals first appear in time?

Answer: 200 Mya

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During this period, the Weapons Station was the Atlantic Fleet's loadout base for all nuclear ballistic missile submarines. Two SSBN "Boomer" squadrons and a submarine tender were homeported at the Weapons Station, while one SSN attack squadron, Submarine Squadron 4, and a submarine tender were homeported at the Naval Base. At the 1996 closure of the station's Polaris Missile Facility Atlantic (POMFLANT), over 2,500 nuclear warheads and their UGM-27 Polaris, UGM-73 Poseidon, and UGM-96 Trident I delivery missiles (SLBM) were stored and maintained, guarded by a U.S. Marine Corps security force company.
What type of security force guards the 2500 nuclear warheads?
A: a U.S. Marine Corps security force company.

Question: During the Five Dynasties and Ten Kingdoms period of China (907960), while the fractured political realm of China saw no threat in a Tibet which was in just as much political disarray, there was little in the way of Sino-Tibetan relations. Few documents involving Sino-Tibetan contacts survive from the Song dynasty (9601279). The Song were far more concerned with countering northern enemy states of the Khitan-ruled Liao dynasty (9071125) and Jurchen-ruled Jin dynasty (11151234).
Is there an answer to this question: Who ruled the Jin dynasty?

Answer: Jurchen

QUES: 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.

What was the correction due to?
What is the answer?
ANS:
length of the year
