Input: Symbiosis
A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This gut flora is made up of cellulose-digesting protozoans or bacteria living in the herbivores' intestines. Coral reefs are the result of mutualisms between coral organisms and various types of algae that live inside them. Most land plants and land ecosystems rely on mutualisms between the plants, which fix carbon from the air, and mycorrhyzal fungi, which help in extracting water and minerals from the ground.

What type of fungus draws liquid and minerals out of the earth?
Output: mycorrhyzal

Input: Article: Beside the introduction of the lute to Spain (Andalusia) by the Moors, another important point of transfer of the lute from Arabian to European culture was Sicily, where it was brought either by Byzantine or later by Muslim musicians. There were singer-lutenists at the court in Palermo following the Norman conquest of the island from the Muslims, and the lute is depicted extensively in the ceiling paintings in the Palermo's royal Cappella Palatina, dedicated by the Norman King Roger II of Sicily in 1140. His Hohenstaufen grandson Frederick II, Holy Roman Emperor (1194 - 1250) continued integrating Muslims into his court, including Moorish musicians. By the 14th century, lutes had disseminated throughout Italy and, probably because of the cultural influence of the Hohenstaufen kings and emperor, based in Palermo, the lute had also made significant inroads into the German-speaking lands.

Now answer this question: Who introduced the lute to Spain?

Output: the Moors

The problem: Answer a question about this article:
Flexible or so-called "unbreakable" records made of unusual materials were introduced by a number of manufacturers at various times during the 78 rpm era. In the UK, Nicole records, made of celluloid or a similar substance coated onto a cardboard core disc, were produced for a few years beginning in 1904, but they suffered from an exceptionally high level of surface noise. In the United States, Columbia Records introduced flexible, fiber-cored "Marconi Velvet Tone Record" pressings in 1907, but the advantages and longevity of their relatively noiseless surfaces depended on the scrupulous use of special gold-plated Marconi Needles and the product was not a success. Thin, flexible plastic records such as the German Phonycord and the British Filmophone and Goodson records appeared around 1930 but also did not last long. The contemporary French Pathe Cellodiscs, made of a very thin black plastic, which uncannily resembles the vinyl "sound sheet" magazine inserts of the 19651985 era, were similarly short-lived. In the US, Hit of the Week records, made of a patented translucent plastic called Durium coated on a heavy brown paper base, were introduced in early 1930. A new issue came out every week and they were sold at newsstands like a weekly magazine. Although inexpensive and commercially successful at first, they soon fell victim to the Great Depression and production in the US ended in 1932. Related Durium records continued to be made somewhat later in the UK and elsewhere, and as remarkably late as 1950 in Italy, where the name "Durium" survived far into the LP era as a trademark on ordinary vinyl records. Despite all these attempts at innovation, shellac compounds continued to be used for the overwhelming majority of commercial 78 rpm records during the lifetime of the format.
What are most 78 rpm records made of?
****
The answer: shellac compounds
