Problem: Buddhism:

According to the scriptures, soon after the parinirvāṇa (from Sanskrit: "highest extinguishment") of Gautama Buddha, the first Buddhist council was held. As with any ancient Indian tradition, transmission of teaching was done orally. The primary purpose of the assembly was to collectively recite the teachings to ensure that no errors occurred in oral transmission. In the first council, Ānanda, a cousin of the Buddha and his personal attendant, was called upon to recite the discourses (sūtras, Pāli suttas) of the Buddha, and, according to some sources, the abhidhamma. Upāli, another disciple, recited the monastic rules (vinaya). Most scholars regard the traditional accounts of the council as greatly exaggerated if not entirely fictitious.[note 36]Richard Gombrich noted Sariputta led communal recitations of the Buddha's teaching for preservation in the Buddha's lifetime in Sangiti Sutta (Digha Nikaya #33), and something similar to the First Council must have taken place to compose Buddhist scriptures.

What are the discourses of the Buddha called?

A: sūtras


Problem: 1853: There were four main events. 1. In the north the Turks captured the border fort of Saint Nicholas in a surprise night attack (27/28 October). They then pushed about 20000 troops across the Cholok River border. Being outnumbered the Russians abandoned Poti and Redut Kale and drew back to Marani. Both sides remained immobile for the next seven months. 2. In the center the Turks moved north from Ardahan to within cannon-shot of Akhaltsike and awaited reinforcements (13 November). The Russians routed them. The claimed losses were 4000 Turks and 400 Russians. 3. In the south about 30000 Turks slowly moved east to the main Russian concentration at Gyumri or Alexandropol (November). They crossed the border and set up artillery south of town. Prince Orbeliani tried to drive them off and found himself trapped. The Turks failed to press their advantage, the remaining Russians rescued Orbeliani and the Turks retired west. Orbeliani lost about 1000 men out of 5000. The Russians now decided to advance, the Turks took up a strong position on the Kars road and attacked. They were defeated in the battle of Başgedikler, losing 6000 men, half their artillery and all their supply train. The Russians lost 1300, including Prince Orbeliani. This was Prince Ellico Orbeliani whose wife was later kidnaped by Shamyl at Tsinandali. 4. At sea the Turks sent a fleet east which was destroyed by Admiral Nakhimov at Sinope.
Who captured the border front of Saint Nicholas during a night attack?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On August 17, 2007, Dell Inc. announced that after an internal investigation into its accounting practices it would restate and reduce earnings from 2003 through to the first quarter of 2007 by a total amount of between $50 million and $150 million, or 2 cents to 7 cents per share. The investigation, begun in November 2006, resulted from concerns raised by the U.S. Securities and Exchange Commission over some documents and information that Dell Inc. had submitted. It was alleged that Dell had not disclosed large exclusivity payments received from Intel for agreeing not to buy processors from rival manufacturer AMD. In 2010 Dell finally paid $100 million to settle the SEC's charges of fraud. Michael Dell and other executives also paid penalties and suffered other sanctions, without admitting or denying the charges.
What year did Dell's external investigation begin?
A: unanswerable


Context and question: The first indigenous group encountered by Columbus were the 250,000 Taínos of Hispaniola who represented the dominant culture in the Greater Antilles and the Bahamas. Within thirty years about 70% of the Taínos had died. They had no immunity to European diseases, so outbreaks of measles and smallpox ravaged their population. Increasing punishment of the Taínos for revolting against forced labour, despite measures put in place by the encomienda, which included religious education and protection from warring tribes, eventually led to the last great Taíno rebellion.
Who was the first group of indigenous people Columbus encountered?
Answer: the 250,000 Taínos of Hispaniola


Question: The League of American Bicyclists gave Tucson a gold rating for bicycle friendliness in late April 2007. Tucson hosts the largest perimeter cycling event in the United States. The ride called "El Tour de Tucson" happens in November on the Saturday before Thanksgiving. El Tour de Tucson produced and promoted by Perimeter Bicycling has as many as 10,000 participants from all over the world, annually. Tucson is one of only nine cities in the U.S. to receive a gold rating or higher for cycling friendliness from the League of American Bicyclists. The city is known for its winter cycling opportunities. Both road and mountain biking are popular in and around Tucson with trail areas including Starr Pass and Fantasy Island.
Is there an answer to this question: Who runs El Tour de Tucson?

Answer: Perimeter Bicycling


Question: The term mainly refers to a mix of lithium and aluminosilicates that yields an array of materials with interesting thermomechanical properties. The most commercially important of these have the distinction of being impervious to thermal shock. Thus, glass-ceramics have become extremely useful for countertop cooking. The negative thermal expansion coefficient (CTE) of the crystalline ceramic phase can be balanced with the positive CTE of the glassy phase. At a certain point (~70% crystalline) the glass-ceramic has a net CTE near zero. This type of glass-ceramic exhibits excellent mechanical properties and can sustain repeated and quick temperature changes up to 1000 °C.
Is there an answer to this question: What proportion of crystalline ceramics yields a product with a CTE of around 0?

Answer:
~70%
