Question: パワーメタル・バンド「ハロウィン」のボーカルは誰？
Context: Keeper of the Seven Keys: Part I is the second studio album by German power metal band Helloween, released in 1987. It marks the first appearance of vocalist Michael Kiske, and is considered the album that created the genre of European-style power metal. Kai Hansen stepped away from doing vocal duties as he had difficulties singing and playing the guitar at the same time during the previous tour. It was an album dominated by Hansen, due to an injury to co-guitarist Michael Weikath which prevented him from performing on much of the album. "Future World" was released as a single and a music video was made for "Halloween" but with 8 minutes omitted from the song. The band originally planned to release "Keeper of the Seven Keys: Part I" and "" as a double album, but their record label refused, insisting that the albums be released separately. Much later in 2010, both albums were released together with bonus tracks.

Question: アーク溶接を発見したのは誰ですか？
Context: In 1800, Sir Humphry Davy discovered the "short-pulse" electrical arc and presented his results in 1801. In 1802, Russian scientist Vasily Petrov created the continuous electric arc, and subsequently published "News of Galvanic-Voltaic Experiments" in 1803, in which he described experiments carried out in 1802. Of great importance in this work was the description of a stable arc discharge and the indication of its possible use for many applications, one being melting metals. In 1808, Davy, who was unaware of Petrov's work, rediscovered the continuous electric arc. In 1881–82 inventors Nikolai Benardos (Russian) and Stanisław Olszewski (Polish) created the first electric arc welding method known as carbon arc welding using carbon electrodes. The advances in arc welding continued with the invention of metal electrodes in the late 1800s by a Russian, Nikolai Slavyanov (1888), and an American, C. L. Coffin (1890). Around 1900, A. P. Strohmenger released a coated metal electrode in Britain, which gave a more stable arc. In 1905, Russian scientist Vladimir Mitkevich proposed using a three-phase electric arc for welding. Alternating current welding was invented by C. J. Holslag in 1919, but did not become popular for another decade.

Question: 硬貨が日本で使われ始めたのはいつから
Context: The earliest coins to reach Japan were Chinese Ban Liang and Wu Zhu coins as well as the coins produced by Wang Mang during the first centuries of the first millennium, these coins have been excavated all over Japan but as Japan's economy wasn't sufficiently developed at the time it is very likely that these coins were more likely to be used as precious objects rather than a means of exchange as rice and cloth served as the main currency of Japan at the time. The first coins produced in Japan are called the "mumonginsen" (無文銀銭, or 'silver coins without inscription') and the copper alloy "Fuhonsen" (富本銭, coins made from an alloy of copper, lead and tin) which were all introduced in the late seventh century, these currencies (alongside other reforms) were based off the Chinese system and were therefore based on the Chinese units of measurement. In modern times the usage of "Fuhonsen" has often been interpreted as charms rather than currency but recent discoveries have uncovered that these copper coins were in fact the first government-made coinage of Japan.

Question: ペットフード大量リコール事件の契機はいつですか？
Context: The 2007 pet food recalls comprise the contamination and wide recall of many brands of cat and dog foods beginning in March 2007, and the ensuing developments involving the human food supply. The recalls in North America, Europe, and South Africa came in response to reports of renal failure in pets. Initially, the recalls were associated with the consumption of mostly wet pet foods made with wheat gluten from a single Chinese company. After more than three weeks of complaints from consumers, the recall began voluntarily with the Canadian company Menu Foods on 16 March 2007, when a company test showed sickness and death in some of the test animals. Soon after, there were numerous media reports of animal deaths as a result of kidney failure. In the following weeks, several other companies who received the contaminated wheat gluten also voluntarily recalled dozens of pet food brands. One month after the initial recall, contaminated rice protein from a different source in China was also identified as being associated with kidney failure in pets in the United States, while contaminated corn gluten was associated with kidney failure with pets in South Africa. As a result of investigating the 2007 pet food recalls, a broader Chinese protein export contamination investigation unfolded, raising concerns about the safety of the human food supply.

Question: シアノバクテリアはいつ発見された？
Context: During the Precambrian, stromatolite communities of microorganisms grew in most marine and non-marine environments in the photic zone. After the Cambrian explosion of marine animals, grazing on the stromatolite mats by herbivores greatly reduced the occurrence of the stromatolites in marine environments. Since then, they are found mostly in hypersaline conditions where grazing invertebrates cannot live (e.g. Shark Bay, Western Australia). Stromatolites provide ancient records of life on Earth by fossil remains which might date from more than 3.5 Ga ago, but this is disputed. the oldest undisputed evidence of cyanobacteria is from 2.1 Ga ago, but there is some evidence for them as far back as 2.7 Ga ago. Oxygen concentrations in the atmosphere remained around or below 1% of today's level until 2.4 Ga ago (the Great Oxygenation Event). The rise in oxygen may have caused a fall in the concentration of atmospheric methane, and triggered the Huronian glaciation from around 2.4 to 2.1 Ga ago. In this way, cyanobacteria may have killed off much of the other bacteria of the time.
Answerable: yes
Answer: 2.1 Ga ago
Question: ヘロインに中毒性はある？
Context: Heroin, also known as diamorphine among other names, is an opioid most commonly used as a recreational drug for its euphoric effects. Medically it is used in several countries to relieve pain or in opioid replacement therapy. Heroin is typically injected, usually into a vein; however, it can also be smoked, snorted or inhaled. The onset of effects is usually rapid and lasts for a few hours.
Common side effects include respiratory depression (decreased breathing), dry mouth, drowsiness, impaired mental function, constipation, and addiction. Side effects of use by injection can include abscesses, infected heart valves, blood borne infections, and pneumonia. After a history of long-term use, withdrawal symptoms can begin within hours of last use. When given by injection into a vein, heroin has two to three times the effect as a similar dose of morphine. It typically comes as a white or brown powder.
Treatment of heroin addiction often includes behavioral therapy and medications. Medications can include buprenorphine, methadone, or naltrexone. A heroin overdose may be treated with naloxone. An estimated 17 million people use opiates of which heroin is the most common. Together with other opioids, they resulted in 122,000 deaths. The total number of heroin users as of 2015 is believed to have increased in Africa, the Americas, and Asia since 2000. In the United States about 1.6 percent of people have used heroin at some point in time with about 950,000 using in the last year. When people die from overdosing on a drug, the drug is usually an opioid and often heroin.
Heroin was first made by C. R. Alder Wright in 1874 from morphine, a natural product of the opium poppy. Internationally, heroin is controlled under Schedules I and IV of the Single Convention on Narcotic Drugs. It is generally illegal to make, possess, or sell heroin without a license. About 448 tons of heroin were made in 2016. In 2015 Afghanistan produced about 66% of the world's opium. Heroin, which is illegally sold, is sometimes mixed with other substances such as sugar, starch, quinine, or strychnine.

Question: 車内信号を最初に導入した鉄道会社はどこ
Context: Originally, all signalling was done by mechanical means. Points and signals were operated locally from individual levers or handles, requiring the signalman to walk between the various pieces of equipment to set them in the required position for each train that passed. Before long, it was realised that control should be concentrated into one building, which came to be known as a signal box. The signal box provided a dry, climate controlled space for the complex interlocking mechanics and also the signalman. The raised design of most signal boxes (which gave rise to the term "tower" in North America) also provided the signalman with a good view of the railway under his control. The first use of a signal box was by the London and Croydon Railway in 1843 to control the junction to Bricklayers' Arms in London.
Answerable: yes
Answer: London and Croydon Railway
Question: バギーカーは四輪駆動？
Context: The 1:10 radio-controlled off-road buggy is a 1:10 scale radio-controlled dune buggy designed for off-road racing.

Context: The idea that matter is made up of discrete units is a very old idea, appearing in many ancient cultures such as Greece and India. The word "atom" (; ""), meaning "uncuttable", was coined by the ancient Greek philosophers Leucippus and his pupil Democritus ( 460 – 370 BC). Democritus taught that atoms were infinite in number, uncreated, and eternal, and that the qualities of an object result from the kind of atoms that compose it. Democritus's atomism was refined and elaborated by the later philosopher Epicurus (341–270 BC). During the Early Middle Ages, atomism was mostly forgotten in western Europe, but survived among some groups of Islamic philosophers. During the twelfth century, atomism became known again in western Europe through references to it in the newly-rediscovered writings of Aristotle.
Answerable: yes
Answer: Leucippus and his pupil Democritus

Question: ルネッサンが終わったのは何故
Context: The end of the Renaissance is as imprecisely marked as its starting point. For many, the rise to power in Florence of the austere monk Girolamo Savonarola in 1494-1498 marks the end of the city's flourishing; for others, the triumphant return of the Medici family to power in 1512 marks the beginning of the late phase in the Renaissance arts called Mannerism. Other accounts trace the end of the Italian Renaissance to the French invasions of the early 16th century and the subsequent conflict between France and Spanish rulers for control of Italian territory. Savonarola rode to power on a widespread backlash over the secularism and indulgence of the Renaissance – his brief rule saw many works of art destroyed in the "Bonfire of the Vanities" in the centre of Florence. With the Medici returned to power, now as Grand Dukes of Tuscany, the counter movement in the church continued. In 1542 the Sacred Congregation of the Inquisition was formed and a few years later the "Index Librorum Prohibitorum" banned a wide array of Renaissance works of literature, which marks the end of the illuminated manuscript together with Giulio Clovio, who is considered the greatest illuminator of the Italian High Renaissance, and arguably the last very notable artist in the long tradition of the illuminated manuscript, before some modern revivals.
Answerable: yes
Answer: the triumphant return of the Medici family to power

Question: 株式の起源はいつ
Context: In the 17th and 18th centuries, the Dutch pioneered several financial innovations that helped lay the foundations of the modern financial system. While the Italian city-states produced the first transferable government bonds, they did not develop the other ingredient necessary to produce a fully fledged capital market: the stock market. In the early 1600s the Dutch East India Company (VOC) became the first company in history to issue bonds and shares of stock to the general public. As Edward Stringham (2015) notes, "companies with transferable shares date back to classical Rome, but these were usually not enduring endeavors and no considerable secondary market existed (Neal, 1997, p. 61)." The Dutch East India Company (founded in the year of 1602) was also the first joint-stock company to get a fixed capital stock and as a result, continuous trade in company stock occurred on the Amsterdam Exchange. Soon thereafter, a lively trade in various derivatives, among which options and repos, emerged on the Amsterdam market. Dutch traders also pioneered short selling – a practice which was banned by the Dutch authorities as early as 1610. Amsterdam-based businessman Joseph de la Vega's "Confusion de Confusiones" (1688) was the earliest known book about stock trading and first book on the inner workings of the stock market (including the stock exchange).

Question: オートバイに使われるタイヤの原料はなんですか？
Context: The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, the first versions of tires were simply bands of metal fitted around wooden wheels to prevent wear and tear. Early rubber tires were solid (not pneumatic). Pneumatic tires are used on many types of vehicles, including cars, bicycles, motorcycles, buses, trucks, heavy equipment, and aircraft. Metal tires are still used on locomotives and railcars, and solid rubber (or other polymer) tires are still used in various non-automotive applications, such as some casters, carts, lawnmowers, and wheelbarrows.
Answerable: yes
Answer: synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds.
Question: スピリチュアルケアを提唱し始めたのは誰？
Context: Ralph Waldo Emerson (1803–1882) was a pioneer of the idea of spirituality as a distinct field. He was one of the major figures in Transcendentalism, an early 19th-century liberal Protestant movement, which was rooted in English and German Romanticism, the Biblical criticism of Johann Gottfried Herder and Friedrich Schleiermacher, the skepticism of Hume, and Neo-Platonism.
The Transcendentalists emphasised an intuitive, experiential approach of religion. Following Schleiermacher, an individual's intuition of truth was taken as the criterion for truth. In the late 18th and early 19th century, the first translations of Hindu texts appeared, which were also read by the Transcendentalists, and influenced their thinking. They also endorsed universalist and Unitarianist ideas, leading to Unitarian Universalism, the idea that there must be truth in other religions as well, since a loving God would redeem all living beings, not just Christians.

Answer: Ralph Waldo Emerson

Question: 日本でたばこの生産がはじまったのはいつ
Context: Japan Tobacco is the successor entity to a nationalized tobacco monopoly first established by the Government of Japan in 1898 to secure tax revenue collections from tobacco leaf sales. In 1904, the government's leaf monopoly was extended to a complete takeover of all tobacco business operations in the nation, including all manufactured tobacco products such as cigarettes. The ostensible reason for the expansion of control was to help fund the 1904–1905 Russo-Japanese War, but because all foreign tobacco interests in Japan at the time were forcibly evicted under the monopolization scheme, this also protected the domestic tobacco business for over eighty years.
Answerable: yes
Answer: 1898
