Input: Portugal
The Muslim population of the region consisted mainly of native Iberian converts to Islam (the so-called Muwallad or Muladi) and to a lesser extent Berbers and Arabs. The Arabs were principally noblemen from Oman; and though few in numbers, they constituted the elite of the population. The Berbers were originally from the Atlas mountains and Rif mountains of North Africa and were essentially nomads. In Portugal, the Muslim population (or "Moors"), relatively small in numbers, stayed in the Algarve region, and south of the Tagus. Today, there are approximately 800 words in the Portuguese language of Arabic origin. The Muslims were expelled from Portugal 300 years earlier than in neighbouring Spain, which is reflected both in Portuguese culture and the language, which is mostly Celtiberian and Vulgar Latin.

How many modern Portugese words have Arabic origins?
Output: 800

Input: Hunting
In the 19th century, southern and central European sport hunters often pursued game only for a trophy, usually the head or pelt of an animal, which was then displayed as a sign of prowess. The rest of the animal was typically discarded. Some cultures, however, disapprove of such waste. In Nordic countries, hunting for trophies wasand still isfrowned upon. Hunting in North America in the 19th century was done primarily as a way to supplement food supplies, although it is now undertaken mainly for sport.[citation needed] The safari method of hunting was a development of sport hunting that saw elaborate travel in Africa, India and other places in pursuit of trophies. In modern times, trophy hunting persists and is a significant industry in some areas.[citation needed]

What was hunting in North American in the 19th century used to supplement?
Output: food supplies

Input: Solar energy
Solar cookers use sunlight for cooking, drying and pasteurization. They can be grouped into three broad categories: box cookers, panel cookers and reflector cookers. The simplest solar cooker is the box cooker first built by Horace de Saussure in 1767. A basic box cooker consists of an insulated container with a transparent lid. It can be used effectively with partially overcast skies and will typically reach temperatures of 90150 C (194302 F). Panel cookers use a reflective panel to direct sunlight onto an insulated container and reach temperatures comparable to box cookers. Reflector cookers use various concentrating geometries (dish, trough, Fresnel mirrors) to focus light on a cooking container. These cookers reach temperatures of 315 C (599 F) and above but require direct light to function properly and must be repositioned to track the Sun.

Horace de Saussure built the first box cooker in what year?
Output: 1767

Input: Hydrogen
Hydrogen's rarer isotopes also each have specific applications. Deuterium (hydrogen-2) is used in nuclear fission applications as a moderator to slow neutrons, and in nuclear fusion reactions. Deuterium compounds have applications in chemistry and biology in studies of reaction isotope effects. Tritium (hydrogen-3), produced in nuclear reactors, is used in the production of hydrogen bombs, as an isotopic label in the biosciences, and as a radiation source in luminous paints.

Where is tritium produced?
Output:
nuclear reactors
