Problem: Background: According to most sources, Omar was born sometime between 1950 and 1962 in a village in Kandahar Province, Kingdom of Afghanistan (in present-day Kandahar Province or Uruzgan Province). Some suggest his birth year as 1950 or 1953, or as late as around 1966. According to a "surprise biography" published by the Taliban in April 2015, he was born in 1960. His exact place of birth is also uncertain; one possibility is a village called Nodeh near the city of Kandahar.
Context: On 4 April 1996, supporters of Mullah Omar bestowed on him the title Amir al-Mu'minin ('myr lmw'mnyn, "Commander of the Faithful"), after he donned a cloak alleged to be that of Muhammad that was locked in a series of chests, held inside the Shrine of the Cloak in the city of Kandahar. Legend decreed that whoever could retrieve the cloak from the chest would be the great Leader of the Muslims, or "Amir al-Mu'minin".  In September 1996, Kabul fell to Mullah Omar and his followers. The civil war continued in the northeast corner of the country, near Tajikistan. The nation was named the Islamic Emirate of Afghanistan in October 1997 and was recognized by Pakistan, Saudi Arabia and the United Arab Emirates. Described as a "reclusive, pious and frugal" leader, Omar very seldom left his residence in the city of Kandahar, and visited Kabul only twice between 1996 and 2001 during his tenure as ruler of Afghanistan. In November 2001, during a radio interview with the BBC, Omar stated: "All Taliban are moderate. There are two things: extremism ['ifraat', or doing something to excess] and conservatism ['tafreet', or doing something insufficiently]. So in that sense, we are all moderates - taking the middle path."  According to Pakistani journalist Rahimullah Yusufzai, Mullah Omar stated in the late 1990s, "We have told Osama [Bin Laden] not to use Afghan soil to carry out political activities as it creates unnecessary confusion about Taliban objectives."  In 1998, despite receiving a personal invitation from Saudi Arabia's ruler, King Fahd, Omar refused to make a pilgrimage to Mecca and wouldn't do one in his lifetime.  Mullah Omar was also "Head of the Supreme Council of Afghanistan".  In July 1999, Mullah Mohammed Omar issued a decree in favor of the preservation of the Bamiyan Buddha statues. Because Afghanistan's Buddhist population no longer exists, so the statues are no longer worshiped, he added: "The government considers the Bamiyan statues as an example of a potential major source of income for Afghanistan from international visitors. The Taliban states that Bamiyan shall not be destroyed but protected."  In early 2000, local Taliban authorities asked for UN assistance to rebuild drainage ditches around tops of the alcoves where the Buddhas were set.  In March 2001, the Buddhas of Bamiyan were destroyed by the Taliban under an edict issued from Mullah Omar, stating: "all the statues around Afghanistan must be destroyed." This prompted an international outcry. Information and Culture Minister Qadratullah Jamal told Associated Press of a decision by 400 religious clerics from across Afghanistan declaring the Buddhist statues against the tenets of Islam. "They came out with a consensus that the statues were against Islam," said Jamal. A statement issued by the ministry of religious affairs of the Taliban regime justified the destruction as being in accordance with Islamic law. The then Taliban ambassador to Pakistan Abdul Salam Zaeef held that the destruction of the Buddhas was finally ordered by Abdul Wali, the Minister for the Propagation of Virtue and the Prevention of Vice.  The Taliban supreme leader Mullah Omar explained why he ordered the statues to be destroyed in an interview:  I did not want to destroy the Bamiyan Buddha. In fact, some foreigners came to me and said they would like to conduct the repair work of the Bamiyan Buddha that had been slightly damaged due to rains. This shocked me. I thought, these callous people have no regard for thousands of living human beings - the Afghans who are dying of hunger, but they are so concerned about non-living objects like the Buddha. This was extremely deplorable. That is why I ordered its destruction. Had they come for humanitarian work, I would have never ordered the Buddha's destruction.
Question: What are Bamiyan Buddhas ?
Answer: In July 1999, Mullah Mohammed Omar issued a decree in favor of the preservation of the Bamiyan Buddha statues.

Background: Isaac Asimov (; c. January 2, 1920 - April 6, 1992) was an American writer and professor of biochemistry at Boston University. He was known for his works of science fiction and popular science. Asimov was a prolific writer who wrote or edited more than 500 books and an estimated 90,000 letters and postcards. His books have been published in 9 of the 10 major categories of the Dewey Decimal Classification.
Context: Asimov was born on an unknown day between October 4, 1919 and January 2, 1920, inclusive. Asimov himself celebrated it on January 2.  Asimov's parents were Anna Rachel (nee Berman) and Judah Asimov, a family of Jewish millers. He was named Isaac after his mother's father, Isaac Berman. When he was born, his family lived in Petrovichi near Klimovichi, which was then Gomel Governorate in the Russian Soviet Federative Socialist Republic (now Smolensk Oblast, Russia). Asimov wrote of his father, "My father, for all his education as an Orthodox Jew, was not Orthodox in his heart", noting that "he didn't recite the myriad prayers prescribed for every action, and he never made any attempt to teach them to me".  In 1921, Asimov and 16 other children in Petrovichi caught double pneumonia. Only Asimov survived. He later had two younger siblings: a sister, Marcia (born Manya, June 17, 1922 - April 2, 2011), and a brother, Stanley (July 25, 1929 - August 16, 1995), who was vice-president of New York Newsday.  His family emigrated to the United States when he was three years old. Since his parents always spoke Yiddish and English with him, he never learned Russian, but he remained fluent in Yiddish as well as English. Growing up in Brooklyn, New York, Asimov taught himself to read at the age of five, and his mother got him into first grade a year early by claiming he was born on September 7, 1919. In third grade he learned about the "error" and insisted on an official correction of the date to January 2.  After becoming established in the U.S., his parents owned a succession of candy stores, in which everyone in the family was expected to work. The candy stores sold newspapers and magazines, a fact that Asimov credited as a major influence in his lifelong love of the written word, as it presented him with an unending supply of new reading material as a child that he could not have otherwise afforded. He became a naturalized U.S. citizen in 1928 at the age of eight.

Asimov was born on an unknown day between October 4, 1919 and January 2, 1920, inclusive. Asimov himself celebrated it on January 2.
