Problem: Given the question: Given the following passage "As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.", answer the following question. Note that the answer is present within the text. Question: Which of the following is not part of the antenna system: radio, interface or free space?
++++++++++++++++++++++++++++++++
The answer is:
interface
input question: Given the following passage "Hydrogen is highly soluble in many rare earth and transition metals and is soluble in both nanocrystalline and amorphous metals. Hydrogen solubility in metals is influenced by local distortions or impurities in the crystal lattice. These properties may be useful when hydrogen is purified by passage through hot palladium disks, but the gas's high solubility is a metallurgical problem, contributing to the embrittlement of many metals, complicating the design of pipelines and storage tanks.", answer the following question. Note that the answer is present within the text. Question: What is it considered when hydrogen is purified????
output answer: useful
Given the following passage "In Rome, Nero and his architects used mosaics to cover some surfaces of walls and ceilings in the Domus Aurea, built 64 AD, and wall mosaics are also found at Pompeii and neighbouring sites. However it seems that it was not until the Christian era that figural wall mosaics became a major form of artistic expression. The Roman church of Santa Costanza, which served as a mausoleum for one or more of the Imperial family, has both religious mosaic and decorative secular ceiling mosaics on a round vault, which probably represent the style of contemporary palace decoration.", answer the following question. Note that the answer is present within the text. Question: What technique was used in 64 AD?
----
Answer: mosaics to cover some surfaces of walls and ceilings
Q: Given the following passage "For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system will experience. An AC circuit will experience 100% voltage reversal, while under-damped DC circuits will experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor. Reversal ratings will often affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections used.", answer the following question. Note that the answer is present within the text. Question: what does voltage reversal cause
A: can dramatically shorten the life expectancy of the capacitor
Question: Given the following passage "During the 200910 school year, there were a total of 10,979 pupils attending classes in Bern. There were 89 kindergarten classes with a total of 1,641 pupils in the municipality. Of the kindergarten pupils, 32.4% were permanent or temporary residents of Switzerland (not citizens) and 40.2% have a different mother language than the classroom language. The municipality had 266 primary classes and 5,040 pupils. Of the primary pupils, 30.1% were permanent or temporary residents of Switzerland (not citizens) and 35.7% have a different mother language than the classroom language. During the same year, there were 151 lower secondary classes with a total of 2,581 pupils. There were 28.7% who were permanent or temporary residents of Switzerland (not citizens) and 32.7% have a different mother language than the classroom language.", answer the following question. Note that the answer is present within the text. Question: Which level of schooling containd the most pupils?
Answer: primary
Please answer this: Given the following passage "Pain is the most common reason for physician consultation in most developed countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general functioning. Psychological factors such as social support, hypnotic suggestion, excitement, or distraction can significantly affect pain's intensity or unpleasantness. In some arguments put forth in physician-assisted suicide or euthanasia debates, pain has been used as an argument to permit terminally ill patients to end their lives.", answer the following question. Note that the answer is present within the text. Question: What is considered a factor in patients ending their own lives?
++++++++
Answer:
pain has been used as an argument to permit terminally ill patients to end their lives
