Input: Catalan language
In Western Catalan, unstressed vowels reduce to five: /e / > [e]; /o / > [o]; /a u i/ remain distinct. This reduction pattern, inherited from Proto-Romance, is also found in Italian and Portuguese. Some Western dialects present further reduction or vowel harmony in some cases.

In what other languages is this pattern found?
Output: Italian and Portuguese

Input: Article: Antarctica continued to become more isolated and finally developed a permanent ice cap. Mountain building in western North America continued, and the Alps started to rise in Europe as the African plate continued to push north into the Eurasian plate, isolating the remnants of Tethys Sea. A brief marine incursion marks the early Oligocene in Europe. There appears to have been a land bridge in the early Oligocene between North America and Europe since the faunas of the two regions are very similar. During the Oligocene, South America was finally detached from Antarctica and drifted north toward North America. It also allowed the Antarctic Circumpolar Current to flow, rapidly cooling the continent.

Now answer this question: In the Oligocene period South America broke free from what other continent?

Output: Antarctica

Article: Several solid dielectrics are available, including paper, plastic, glass, mica and ceramic materials. Paper was used extensively in older devices and offers relatively high voltage performance. However, it is susceptible to water absorption, and has been largely replaced by plastic film capacitors. Plastics offer better stability and ageing performance, which makes them useful in timer circuits, although they may be limited to low operating temperatures and frequencies. Ceramic capacitors are generally small, cheap and useful for high frequency applications, although their capacitance varies strongly with voltage and they age poorly. They are broadly categorized as class 1 dielectrics, which have predictable variation of capacitance with temperature or class 2 dielectrics, which can operate at higher voltage. Glass and mica capacitors are extremely reliable, stable and tolerant to high temperatures and voltages, but are too expensive for most mainstream applications. Electrolytic capacitors and supercapacitors are used to store small and larger amounts of energy, respectively, ceramic capacitors are often used in resonators, and parasitic capacitance occurs in circuits wherever the simple conductor-insulator-conductor structure is formed unintentionally by the configuration of the circuit layout.

Question: What sort of circuit are plastic capacitors especially useful for?
Ans: timer circuits

Here is a question about this article: Iranian cuisine is diverse due to its variety of ethnic groups and the influence of other cultures. Herbs are frequently used along with fruits such as plums, pomegranates, quince, prunes, apricots, and raisins. Iranians usually eat plain yogurt with lunch and dinner; it is a staple of the diet in Iran. To achieve a balanced taste, characteristic flavourings such as saffron, dried limes, cinnamon, and parsley are mixed delicately and used in some special dishes. Onions and garlic are normally used in the preparation of the accompanying course, but are also served separately during meals, either in raw or pickled form. Iran is also famous for its caviar.
What is the answer to this question: What delicacy is Iran famous for?
****
So... caviar

Under the 1963 constitution, Massamba-Debat was elected President for a five-year term. During Massamba-Debat's term in office the regime adopted "scientific socialism" as the country's constitutional ideology. In 1965, Congo established relations with the Soviet Union, the People's Republic of China, North Korea and North Vietnam. Massamba-Debat's regime also invited several hundred Cuban army troops into the country to train his party's militia units and these troops helped his government survive a coup in 1966 led by paratroopers loyal to future President Marien Ngouabi. Nevertheless, Massamba-Debat was unable to reconcile various institutional, tribal and ideological factions within the country and his regime ended abruptly with a bloodless coup d'etat in September 1968.
What was a term that could describe the political philosophy of the Congo under Massamba-Debat?
****
The answer: scientific socialism

The problem: Answer a question about this article:
Western philosophy regarded emotion in varying ways. In stoic theories it was seen as a hindrance to reason and therefore a hindrance to virtue. Aristotle believed that emotions were an essential component of virtue. In the Aristotelian view all emotions (called passions) corresponded to appetites or capacities. During the Middle Ages, the Aristotelian view was adopted and further developed by scholasticism and Thomas Aquinas in particular. There are also theories of emotions in the works of philosophers such as Rene Descartes, Niccolo Machiavelli, Baruch Spinoza and David Hume. In the 19th century emotions were considered adaptive and were studied more frequently from an empiricist psychiatric perspective.
What thinker believed that emotions were necessary for virtue?
****
The answer:
Aristotle
