Problem: Please answer a question about the following article about History of science:
Indian astronomer and mathematician Aryabhata (476-550), in his Aryabhatiya (499) introduced a number of trigonometric functions (including sine, versine, cosine and inverse sine), trigonometric tables, and techniques and algorithms of algebra. In 628 AD, Brahmagupta suggested that gravity was a force of attraction. He also lucidly explained the use of zero as both a placeholder and a decimal digit, along with the Hindu-Arabic numeral system now used universally throughout the world. Arabic translations of the two astronomers' texts were soon available in the Islamic world, introducing what would become Arabic numerals to the Islamic World by the 9th century. During the 14th–16th centuries, the Kerala school of astronomy and mathematics made significant advances in astronomy and especially mathematics, including fields such as trigonometry and analysis. In particular, Madhava of Sangamagrama is considered the "founder of mathematical analysis".
What language did the work of Brahmagupta and Aryabhata have to be translated from?
A: Arabic
Problem: Please answer a question about the following article about Middle Ages:
Changes also took place among laymen, as aristocratic culture focused on great feasts held in halls rather than on literary pursuits. Clothing for the elites was richly embellished with jewels and gold. Lords and kings supported entourages of fighters who formed the backbone of the military forces.[I] Family ties within the elites were important, as were the virtues of loyalty, courage, and honour. These ties led to the prevalence of the feud in aristocratic society, examples of which included those related by Gregory of Tours that took place in Merovingian Gaul. Most feuds seem to have ended quickly with the payment of some sort of compensation. Women took part in aristocratic society mainly in their roles as wives and mothers of men, with the role of mother of a ruler being especially prominent in Merovingian Gaul. In Anglo-Saxon society the lack of many child rulers meant a lesser role for women as queen mothers, but this was compensated for by the increased role played by abbesses of monasteries. Only in Italy does it appear that women were always considered under the protection and control of a male relative.
In what society did women have status as abbesses?
A: Anglo-Saxon
Problem: Please answer a question about the following article about Rule of law:
In India, the longest constitutional text in the history of the world has governed that country since 1950. Although the Constitution of India may have been intended to provide details that would limit the opportunity for judicial discretion, the more text there is in a constitution the greater opportunity the judiciary may have to exercise judicial review. According to Indian journalist Harish Khare, "The rule of law or rather the Constitution [is] in danger of being supplanted by the rule of judges."
In what year was India's constitution drafted?
A: 1950
Problem: Please answer a question about the following article about Architecture:
According to Vitruvius, the architect should strive to fulfill each of these three attributes as well as possible. Leon Battista Alberti, who elaborates on the ideas of Vitruvius in his treatise, De Re Aedificatoria, saw beauty primarily as a matter of proportion, although ornament also played a part. For Alberti, the rules of proportion were those that governed the idealised human figure, the Golden mean. The most important aspect of beauty was therefore an inherent part of an object, rather than something applied superficially; and was based on universal, recognisable truths. The notion of style in the arts was not developed until the 16th century, with the writing of Vasari: by the 18th century, his Lives of the Most Excellent Painters, Sculptors, and Architects had been translated into Italian, French, Spanish and English.
In what century did "style" as an artistic concept arise?
A:
16th
