input: Please answer the following: Question: "Hot cathode and cold cathode ion gauges are the same except for how they each do what?" Context: "Ion gauges are used in ultrahigh vacuum. They come in two types: hot cathode and cold cathode. In the hot cathode version an electrically heated filament produces an electron beam. The electrons travel through the gauge and ionize gas molecules around them. The resulting ions are collected at a negative electrode. The current depends on the number of ions, which depends on the pressure in the gauge. Hot cathode gauges are accurate from 103 torr to 1010 torr. The principle behind cold cathode version is the same, except that electrons are produced in a discharge created by a high voltage electrical discharge. Cold cathode gauges are accurate from 102 torr to 109 torr. Ionization gauge calibration is very sensitive to construction geometry, chemical composition of gases being measured, corrosion and surface deposits. Their calibration can be invalidated by activation at atmospheric pressure or low vacuum. The composition of gases at high vacuums will usually be unpredictable, so a mass spectrometer must be used in conjunction with the ionization gauge for accurate measurement." Answer:
++++++++++
output: produces an electron beam

Please answer this: Question: "What is Jupiter's environment made up of?" Context: "Neptune is similar in composition to Uranus, and both have compositions that differ from those of the larger gas giants, Jupiter and Saturn. Like Jupiter and Saturn, Neptune's atmosphere is composed primarily of hydrogen and helium, along with traces of hydrocarbons and possibly nitrogen, but contains a higher proportion of "ices" such as water, ammonia, and methane. However, its interior, like that of Uranus, is primarily composed of ices and rock, and hence Uranus and Neptune are normally considered "ice giants" to emphasise this distinction. Traces of methane in the outermost regions in part account for the planet's blue appearance." Answer:
++++++++
Answer: hydrogen and helium

Problem: Question: "How many Euros is 879.36 Swiss francs?" Context: "As of 2003[update] the average price to rent an average apartment in Bern was 1108.92 Swiss francs (CHF) per month (US$890, 500, 710 approx. exchange rate from 2003). The average rate for a one-room apartment was 619.82 CHF (US$500, 280, 400), a two-room apartment was about 879.36 CHF (US$700, 400, 560), a three-room apartment was about 1040.54 CHF (US$830, 470, 670) and a six or more room apartment cost an average of 2094.80 CHF (US$1680, 940, 1340). The average apartment price in Bern was 99.4% of the national average of 1116 CHF. The vacancy rate for the municipality, in 2010[update], was 0.45%." Answer:

A: 560

Problem: Given the question: Question: "What does the second S stand for in ISS?" Context: "The Russian R-7 rocket family, which launched the first Sputnik at the beginning of the space race, is still in use today. It services the International Space Station (ISS) as the launcher for both the Soyuz and Progress spacecraft. It also ferries both Russian and American crews to and from the station." Answer:
++++++++++++++++++++++++++++++++
The answer is:
Station

input question: Question: "Who died later, Xiang Yu or Liu Bang?" Context: "China's first imperial dynasty was the Qin dynasty (221206 BC). The Qin unified the Chinese Warring States by conquest, but their empire became unstable after the death of the first emperor Qin Shi Huangdi. Within four years, the dynasty's authority had collapsed in the face of rebellion. Two former rebel leaders, Xiang Yu (d. 202 BC) of Chu and Liu Bang (d. 195 BC) of Han, engaged in a war to decide who would become hegemon of China, which had fissured into 18 kingdoms, each claiming allegiance to either Xiang Yu or Liu Bang. Although Xiang Yu proved to be a capable commander, Liu Bang defeated him at Battle of Gaixia (202 BC), in modern-day Anhui. Liu Bang assumed the title "emperor" (huangdi) at the urging of his followers and is known posthumously as Emperor Gaozu (r. 202195 BC). Chang'an was chosen as the new capital of the reunified empire under Han." Answer:???
output answer: Liu Bang

input question: Question: "Of chestnut and ash, which one is the same type of sapwood as mulberry?" Context: "The term heartwood derives solely from its position and not from any vital importance to the tree. This is evidenced by the fact that a tree can thrive with its heart completely decayed. Some species begin to form heartwood very early in life, so having only a thin layer of live sapwood, while in others the change comes slowly. Thin sapwood is characteristic of such species as chestnut, black locust, mulberry, osage-orange, and sassafras, while in maple, ash, hickory, hackberry, beech, and pine, thick sapwood is the rule. Others never form heartwood." Answer:???
output answer:
chestnut
