Problem: Please answer a question about the following article about Red:
The 19th century also saw the use of red in art to create specific emotions, not just to imitate nature. It saw the systematic study of color theory, and particularly the study of how complementary colors such as red and green reinforced each other when they were placed next to each other. These studies were avidly followed by artists such as Vincent van Gogh. Describing his painting, The Night Cafe, to his brother Theo in 1888, Van Gogh wrote: "I sought to express with red and green the terrible human passions. The hall is blood red and pale yellow, with a green billiard table in the center, and four lamps of lemon yellow, with rays of orange and green. Everywhere it is a battle and antithesis of the most different reds and greens."
In what year was The Night Cafe painted?
A: 1888


Question: Read this and answer the question

Only one 5.1 surround sound option exists on a given LaserDisc (either Dolby Digital or DTS), so if surround sound is desired, the disc must be matched to the capabilities of the playback equipment (LD Player and Receiver/Decoder) by the purchaser. A fully capable LaserDisc playback system includes a newer LaserDisc player that is capable of playing digital tracks, has a digital optical output for digital PCM and DTS audio, is aware of AC-3 audio tracks, and has an AC-3 coaxial output; an external or internal AC-3 RF demodulator and AC-3 decoder; and a DTS decoder. Many 1990s A/V receivers combine the AC-3 decoder and DTS decoder logic, but an integrated AC-3 demodulator is rare both in LaserDisc players and in later A/V receivers.

What type of decoder logic is common in 1990s A/V receivers?
Answer: DTS


Problem: Historians agree that Napoleon's remarkable personality was one key to his influence. They emphasize the strength of his ambition that took him from an obscure village to command of most of Europe. George F. E. Rudé stresses his "rare combination of will, intellect and physical vigour." At 5 ft 6 in (168 cm), he was not physically imposing but in one-on-one situations he typically had a hypnotic impact on people and seemingly bent the strongest leaders to his will. He understood military technology, but was not an innovator in that regard. He was an innovator in using the financial, bureaucratic, and diplomatic resources of France. He could rapidly dictate a series of complex commands to his subordinates, keeping in mind where major units were expected to be at each future point, and like a chess master, "seeing" the best plays moves ahead.
What is the name of the historian who stresses Napoleon's "rare combination of will, intellect, and physical vigour?"
The answer is the following: George F. E. Rudé


Hunting also has a significant financial impact in the United States, with many companies specialising in hunting equipment or speciality tourism. Many different technologies have been created to assist hunters, even including iPhone applications. Today's hunters come from a broad range of economic, social, and cultural backgrounds. In 2001, over thirteen million hunters averaged eighteen days hunting, and spent over $20.5 billion on their sport.[citation needed] In the US, proceeds from hunting licenses contribute to state game management programs, including preservation of wildlife habitat.
How much did hunters spend in 2001?
over $20.5 billion


Input: Infrared
Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 900–14,000 nanometers or 0.9–14 μm) and produce images of that radiation. Since infrared radiation is emitted by all objects based on their temperatures, according to the black body radiation law, thermography makes it possible to "see" one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature, therefore thermography allows one to see variations in temperature (hence the name).

What type of cameras see infrared radiation?
Output: Thermographic


Problem: Please answer a question about the following article about Mesozoic:
The climatic changes of the late Jurassic and Cretaceous provided for further adaptive radiation. The Jurassic was the height of archosaur diversity, and the first birds and eutherian mammals also appeared. Angiosperms radiated sometime in the early Cretaceous, first in the tropics, but the even temperature gradient allowed them to spread toward the poles throughout the period. By the end of the Cretaceous, angiosperms dominated tree floras in many areas, although some evidence suggests that biomass was still dominated by cycad and ferns until after the Cretaceous–Paleogene extinction.
What event produced further adaptations during  the Jurassic and Cretaceous periods?
A:
climatic changes
