Problem: Late Middle Ages:

Music was an important part of both secular and spiritual culture, and in the universities it made up part of the quadrivium of the liberal arts. From the early 13th century, the dominant sacred musical form had been the motet; a composition with text in several parts. From the 1330s and onwards, emerged the polyphonic style, which was a more complex fusion of independent voices. Polyphony had been common in the secular music of the Provençal troubadours. Many of these had fallen victim to the 13th-century Albigensian Crusade, but their influence reached the papal court at Avignon.

What isn't the term for the four subjects that comprised the liberal arts in medieval universities?

Problem: Behind the scenes, the bookers in a company will place the title on the most accomplished performer, or those the bookers believe will generate fan interest in terms of event attendance and television viewership. Lower ranked titles may also be used on the performers who show potential, thus allowing them greater exposure to the audience. However other circumstances may also determine the use of a championship. A combination of a championship's lineage, the caliber of performers as champion, and the frequency and manner of title changes, dictates the audience's perception of the title's quality, significance and reputation.
Who might they use a lower ranked title on?
---
Answer: performers who show potential


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The central Sahara is estimated to include five hundred species of plants, which is extremely low considering the huge extent of the area. Plants such as acacia trees, palms, succulents, spiny shrubs, and grasses have adapted to the arid conditions, by growing lower to avoid water loss by strong winds, by storing water in their thick stems to use it in dry periods, by having long roots that travel horizontally to reach the maximum area of water and to find any surface moisture and by having small thick leaves or needles to prevent water loss by evapo-transpiration. Plant leaves may dry out totally and then recover.
Why do many plants grow higher than normal in the Sahara?
A: unanswerable


Context and question: The disadvantage of the ski-jump is the penalty it exacts on aircraft size, payload, and fuel load (and thus range); heavily laden aircraft can not launch using a ski-jump because their high loaded weight requires either a longer takeoff roll than is possible on a carrier deck, or assistance from a catapult or JATO rocket. For example, the Russian Su-33 is only able to launch from the carrier Admiral Kuznetsov with a minimal armament and fuel load. Another disadvantage is on mixed flight deck operations where helicopters are also present such as a US Landing Helicopter Dock or Landing Helicopter Assault amphibious assault ship a ski jump is not included as this would eliminate one or more helicopter landing areas, this flat deck limits the loading of Harriers but is somewhat mitigated by the longer rolling start provided by a long flight deck compared to many STOVL carriers.
What do lightly laden aircraft sometimes require the assistance from?
Answer: unanswerable


Question: The Mongol Yuan dynasty, through the Bureau of Buddhist and Tibetan Affairs, or Xuanzheng Yuan, ruled Tibet through a top-level administrative department. One of the department's purposes was to select a dpon-chen ('great administrator'), usually appointed by the lama and confirmed by the Mongol emperor in Beijing. The Sakya lama retained a degree of autonomy, acting as the political authority of the region, while the dpon-chen held administrative and military power. Mongol rule of Tibet remained separate from the main provinces of China, but the region existed under the administration of the Yuan dynasty. If the Sakya lama ever came into conflict with the dpon-chen, the dpon-chen had the authority to send Chinese troops into the region.
Is there an answer to this question: What is the Yuan term for the Bureau of Buddhist and Tibetan Affairs?

Answer: unanswerable


Question: Near-infrared is the region closest in wavelength to the radiation detectable by the human eye, mid- and far-infrared are progressively further from the visible spectrum. Other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (the common silicon detectors are sensitive to about 1,050 nm, while InGaAs's sensitivity starts around 950 nm and ends between 1,700 and 2,600 nm, depending on the specific configuration). Unfortunately, international standards for these specifications are not currently available.
Is there an answer to this question: Along with the emission peaks and vs. bands mechanisms, what other physical mechanism is used to define common silicon detectors?

Answer:
unanswerable
