[Q]: Given the following passage "Since LED efficacy is inversely proportional to operating temperature, LED technology is well suited for supermarket freezer lighting. Because LEDs produce less waste heat than incandescent lamps, their use in freezers can save on refrigeration costs as well. However, they may be more susceptible to frost and snow buildup than incandescent lamps, so some LED lighting systems have been designed with an added heating circuit. Additionally, research has developed heat sink technologies that will transfer heat produced within the junction to appropriate areas of the light fixture.", answer the following question. Note that the answer is present within the text. Question: What did incandescent lamps in a freezer have less problem with?
****
[A]: frost and snow buildup

input: Please answer the following: Given the following passage "The mandolin has been used extensively in the traditional music of England and Scotland for generations. Simon Mayor is a prominent British player who has produced six solo albums, instructional books and DVDs, as well as recordings with his mandolin quartet the Mandolinquents. The instrument has also found its way into British rock music. The mandolin was played by Mike Oldfield (and introduced by Vivian Stanshall) on Oldfield's album Tubular Bells, as well as on a number of his subsequent albums (particularly prominently on Hergest Ridge (1974) and Ommadawn (1975)). It was used extensively by the British folk-rock band Lindisfarne, who featured two members on the instrument, Ray Jackson and Simon Cowe, and whose "Fog on the Tyne" was the biggest selling UK album of 1971-1972. The instrument was also used extensively in the UK folk revival of the 1960s and 1970s with bands such as Fairport Convention and Steeleye Span taking it on as the lead instrument in many of their songs. Maggie May by Rod Stewart, which hit No. 1 on both the British charts and the Billboard Hot 100, also featured Jackson's playing. It has also been used by other British rock musicians. Led Zeppelin's bassist John Paul Jones is an accomplished mandolin player and has recorded numerous songs on mandolin including Going to California and That's the Way; the mandolin part on The Battle of Evermore is played by Jimmy Page, who composed the song. Other Led Zeppelin songs featuring mandolin are Hey Hey What Can I Do, and Black Country Woman. Pete Townshend of The Who played mandolin on the track Mike Post Theme, along with many other tracks on Endless Wire. McGuinness Flint, for whom Graham Lyle played the mandolin on their most successful single, When I'm Dead And Gone, is another example. Lyle was also briefly a member of Ronnie Lane's Slim Chance, and played mandolin on their hit How Come. One of the more prominent early mandolin players in popular music was Robin Williamson in The Incredible String Band. Ian Anderson of Jethro Tull is a...", answer the following question. Note that the answer is present within the text. Question: Who had more than two people playing the instrument?
++++++++++
output: Mandolinquents

Please answer this: Given the following passage "Resistance to infection (immunity) may be acquired following a disease, by asymptomatic carriage of the pathogen, by harboring an organism with a similar structure (crossreacting), or by vaccination. Knowledge of the protective antigens and specific acquired host immune factors is more complete for primary pathogens than for opportunistic pathogens. There is also the phenomenon of herd immunity which offers a measure of protection to those otherwise vulnerable people when a large enough proportion of the population has acquired immunity from certain infections.", answer the following question. Note that the answer is present within the text. Question: Immunity may be acquired through vaccination, crossreacting, asymptomatic carriage, and what else?
++++++++
Answer: following a disease

Problem: Given the following passage "Hydrogen was liquefied for the first time by James Dewar in 1898 by using regenerative cooling and his invention, the vacuum flask. He produced solid hydrogen the next year. Deuterium was discovered in December 1931 by Harold Urey, and tritium was prepared in 1934 by Ernest Rutherford, Mark Oliphant, and Paul Harteck. Heavy water, which consists of deuterium in the place of regular hydrogen, was discovered by Urey's group in 1932. Francois Isaac de Rivaz built the first de Rivaz engine, an internal combustion engine powered by a mixture of hydrogen and oxygen in 1806. Edward Daniel Clarke invented the hydrogen gas blowpipe in 1819. The Dobereiner's lamp and limelight were invented in 1823.", answer the following question. Note that the answer is present within the text. Question: What was invented after de Rivaz engine?

A: hydrogen gas blowpipe

Problem: Given the question: Given the following passage "for any constant c. Matrix groups over these fields fall under this regime, as do adele rings and adelic algebraic groups, which are basic to number theory. Galois groups of infinite field extensions such as the absolute Galois group can also be equipped with a topology, the so-called Krull topology, which in turn is central to generalize the above sketched connection of fields and groups to infinite field extensions. An advanced generalization of this idea, adapted to the needs of algebraic geometry, is the etale fundamental group.", answer the following question. Note that the answer is present within the text. Question: How does the idea change?
++++++++++++++++++++++++++++++++
The answer is:
An advanced generalization of this idea, adapted to the needs of algebraic geometry, is the etale fundamental group

Problem: Given the following passage "In higher organisms (like people), these two modes of perception combine into what Whitehead terms "symbolic reference", which links appearance with causation in a process that is so automatic that both people and animals have difficulty refraining from it. By way of illustration, Whitehead uses the example of a person's encounter with a chair. An ordinary person looks up, sees a colored shape, and immediately infers that it is a chair. However, an artist, Whitehead supposes, "might not have jumped to the notion of a chair", but instead "might have stopped at the mere contemplation of a beautiful color and a beautiful shape." This is not the normal human reaction; most people place objects in categories by habit and instinct, without even thinking about it. Moreover, animals do the same thing. Using the same example, Whitehead points out that a dog "would have acted immediately on the hypothesis of a chair and would have jumped onto it by way of using it as such." In this way symbolic reference is a fusion of pure sense perceptions on the one hand and causal relations on the other, and that it is in fact the causal relationships that dominate the more basic mentality (as the dog illustrates), while it is the sense perceptions which indicate a higher grade mentality (as the artist illustrates).", answer the following question. Note that the answer is present within the text. Question: Which is not a last name, Whitehead or Infers?

A:
infers
