Input: Read this: Infrared vibrational spectroscopy (see also near-infrared spectroscopy) is a technique that can be used to identify molecules by analysis of their constituent bonds. Each chemical bond in a molecule vibrates at a frequency characteristic of that bond. A group of atoms in a molecule (e.g., CH2) may have multiple modes of oscillation caused by the stretching and bending motions of the group as a whole. If an oscillation leads to a change in dipole in the molecule then it will absorb a photon that has the same frequency. The vibrational frequencies of most molecules correspond to the frequencies of infrared light. Typically, the technique is used to study organic compounds using light radiation from 4000–400 cm−1, the mid-infrared. A spectrum of all the frequencies of absorption in a sample is recorded. This can be used to gain information about the sample composition in terms of chemical groups present and also its purity (for example, a wet sample will show a broad O-H absorption around 3200 cm−1).
Question: What are multiple modes of oscillation in a spectrum caused by?

Output: unanswerable


QUES: The early history of Portugal is shared with the rest of the Iberian Peninsula located in South Western Europe. The name of Portugal derives from the joined Romano-Celtic name Portus Cale. The region was settled by Pre-Celts and Celts, giving origin to peoples like the Gallaeci, Lusitanians, Celtici and Cynetes, visited by Phoenicians and Carthaginians, incorporated in the Roman Republic dominions as Lusitania and part of Gallaecia, after 45 BC until 298 AD, settled again by Suebi, Buri, and Visigoths, and conquered by Moors. Other influences include some 5th-century vestiges of Alan settlement, which were found in Alenquer (old Germanic Alankerk, from Alan+kerk; meaning church of the Alan (people), Coimbra and Lisbon.

QUES: He turned to medicine at 16, and not only learned medical theory, but also by gratuitous attendance of the sick had, according to his own account, discovered new methods of treatment. The teenager achieved full status as a qualified physician at age 18, and found that "Medicine is no hard and thorny science, like mathematics and metaphysics, so I soon made great progress; I became an excellent doctor and began to treat patients, using approved remedies." The youthful physician's fame spread quickly, and he treated many patients without asking for payment.

West is one of the best-selling artists of all time, having sold more than 32 million albums and 100 million digital downloads worldwide. He has won a total of 21 Grammy Awards, making him one of the most awarded artists of all time and the most Grammy-awarded artist of his age. Three of his albums rank on Rolling Stone's 2012 "500 Greatest Albums of All Time" list; two of his albums feature at first and eighth, respectively, in Pitchfork Media's The 100 Best Albums of 2010–2014. He has also been included in a number of Forbes annual lists. Time named him one of the 100 most influential people in the world in 2005 and 2015.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many of Kanye West's albums were recognized by Rolling Stone Magazine?
Ah, so.. 3


Question: In Serbia, the Serbian language is the official one, while both Serbian and Croatian are official in the province of Vojvodina. A large Bosniak minority is present in the southwest region of Sandžak, but the "official recognition" of Bosnian language is moot. Bosnian is an optional course in 1st and 2nd grade of the elementary school, while it is also in official use in the municipality of Novi Pazar. However, its nomenclature is controversial, as there is incentive that it is referred to as "Bosniak" (bošnjački) rather than "Bosnian" (bosanski) (see Bosnian language for details).
Try to answer this question if possible: Where is a large Serbian minority located?
Answer: unanswerable


Context and question: On July 26, 1931, at a convention in Columbus, Ohio, Rutherford introduced the new name—Jehovah's witnesses—based on Isaiah 43:10: "Ye are my witnesses, saith Jehovah, and my servant whom I have chosen"—which was adopted by resolution. The name was chosen to distinguish his group of Bible Students from other independent groups that had severed ties with the Society, as well as symbolize the instigation of new outlooks and the promotion of fresh evangelizing methods. In 1932, Rutherford eliminated the system of locally elected elders and in 1938, introduced what he called a "theocratic" (literally, God-ruled) organizational system, under which appointments in congregations worldwide were made from the Brooklyn headquarters.
In what year did Rutherford take over leadership of the Watch Tower Society?
