Input: History of science
There are many notable contributors to the field of Chinese science throughout the ages. One of the best examples would be Shen Kuo (1031–1095), a polymath scientist and statesman who was the first to describe the magnetic-needle compass used for navigation, discovered the concept of true north, improved the design of the astronomical gnomon, armillary sphere, sight tube, and clepsydra, and described the use of drydocks to repair boats. After observing the natural process of the inundation of silt and the find of marine fossils in the Taihang Mountains (hundreds of miles from the Pacific Ocean), Shen Kuo devised a theory of land formation, or geomorphology. He also adopted a theory of gradual climate change in regions over time, after observing petrified bamboo found underground at Yan'an, Shaanxi province. If not for Shen Kuo's writing, the architectural works of Yu Hao would be little known, along with the inventor of movable type printing, Bi Sheng (990-1051). Shen's contemporary Su Song (1020–1101) was also a brilliant polymath, an astronomer who created a celestial atlas of star maps, wrote a pharmaceutical treatise with related subjects of botany, zoology, mineralogy, and metallurgy, and had erected a large astronomical clocktower in Kaifeng city in 1088. To operate the crowning armillary sphere, his clocktower featured an escapement mechanism and the world's oldest known use of an endless power-transmitting chain drive.

Who discovered the idea of true north?
Output: Shen Kuo


Input: Article: The northern supercontinent of Laurasia began to break up, as Europe, Greenland and North America drifted apart. In western North America, mountain building started in the Eocene, and huge lakes formed in the high flat basins among uplifts. In Europe, the Tethys Sea finally vanished, while the uplift of the Alps isolated its final remnant, the Mediterranean, and created another shallow sea with island archipelagos to the north. Though the North Atlantic was opening, a land connection appears to have remained between North America and Europe since the faunas of the two regions are very similar. India continued its journey away from Africa and began its collision with Asia, creating the Himalayan orogeny.

Now answer this question: In the Eocene, in Europe, which sea ceased to be?

Output: Tethys Sea


Article: Illustrated humour periodicals were popular in 19th-century Britain, the earliest of which was the short-lived The Glasgow Looking Glass in 1825. The most popular was Punch, which popularized the term cartoon for its humorous caricatures. On occasion the cartoons in these magazines appeared in sequences; the character Ally Sloper featured in the earliest serialized comic strip when the character began to feature in its own weekly magazine in 1884.

Question: When did Ally Sloper first appear?
Ans: 1884


Here is a question about this article: Many Sanskrit loanwords are also found in Austronesian languages, such as Javanese, particularly the older form in which nearly half the vocabulary is borrowed. Other Austronesian languages, such as traditional Malay and modern Indonesian, also derive much of their vocabulary from Sanskrit, albeit to a lesser extent, with a larger proportion derived from Arabic. Similarly, Philippine languages such as Tagalog have some Sanskrit loanwords, although more are derived from Spanish. A Sanskrit loanword encountered in many Southeast Asian languages is the word bhāṣā, or spoken language, which is used to refer to the names of many languages.
What is the answer to this question: Where does traditional Malay get many of its loanwords?
****
So... Sanskrit

In summer of 1986, Queen went on their final tour with Freddie Mercury. A sold-out tour in support of A Kind of Magic, once again they hired Spike Edney, leading to him being dubbed the unofficial fifth member.
