Input: Solar energy
Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight and enable solar energy to be harnessed at different levels around the world, mostly depending on distance from the equator. Although solar energy refers primarily to the use of solar radiation for practical ends, all renewable energies, other than geothermal and tidal, derive their energy from the Sun in a direct or indirect way.

Which renewable energies do not acquire their energy from the sun?
Output: geothermal and tidal

Input: Late Middle Ages
The Bulgarian Empire was in decline by the 14th century, and the ascendancy of Serbia was marked by the Serbian victory over the Bulgarians in the Battle of Velbazhd in 1330. By 1346, the Serbian king Stefan Dusan had been proclaimed emperor. Yet Serbian dominance was short-lived; the Serbian army led by the Lazar Hrebljevanovic was defeated by the Ottomans at the Battle of Kosovo in 1389, where most of the Serbian nobility was killed and the south of the country came under Ottoman occupation, as much of southern Bulgaria had become Ottoman territory in 1371. Northern remnants of Bulgaria were finally conquered by 1396, Serbia fell in 1459, Bosnia in 1463, and Albania was finally subordinated in 1479 only a few years after the death of Skanderbeg. Belgrade, an Hungarian domain at the time, was the last large Balkan city to fall under Ottoman rule, in 1521. By the end of the medieval period, the entire Balkan peninsula was annexed by, or became vassal to, the Ottomans.

Who led led the Serbian Army at the Battle of Kosovo?
Output: Lazar Hrebljevanovic

Input: Queen Victoria
In 1830, the Duchess of Kent and Conroy took Victoria across the centre of England to visit the Malvern Hills, stopping at towns and great country houses along the way. Similar journeys to other parts of England and Wales were taken in 1832, 1833, 1834 and 1835. To the King's annoyance, Victoria was enthusiastically welcomed in each of the stops. William compared the journeys to royal progresses and was concerned that they portrayed Victoria as his rival rather than his heiress presumptive. Victoria disliked the trips; the constant round of public appearances made her tired and ill, and there was little time for her to rest. She objected on the grounds of the King's disapproval, but her mother dismissed his complaints as motivated by jealousy, and forced Victoria to continue the tours. At Ramsgate in October 1835, Victoria contracted a severe fever, which Conroy initially dismissed as a childish pretence. While Victoria was ill, Conroy and the Duchess unsuccessfully badgered her to make Conroy her private secretary. As a teenager, Victoria resisted persistent attempts by her mother and Conroy to appoint him to her staff. Once queen, she banned him from her presence, but he remained in her mother's household.

What town did Victoria visit in the center of England on her trip with the Dutchess of kent and Conroy?
Output:
Malvern Hills
