Please answer this: Question: "When copper is used as an allow in machinery, for which elements is it used?" Context: "The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a pure metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics." Answer:
++++++++
Answer: intricate parts

Problem: Question: "What was a direct result of the poor economy?" Context: "During the presidential referendum in Egypt, Nasser was re-elected to a second term as UAR president and took his oath on 25 March 1965. He was the only candidate for the position, with virtually all of his political opponents forbidden by law from running for office, and his fellow party members reduced to mere followers. That same year, Nasser had the Muslim Brotherhood chief ideologue Sayyed Qutb imprisoned. Qutb was charged and found guilty by the court of plotting to assassinate Nasser, and was executed in 1966. Beginning in 1966, as Egypt's economy slowed and government debt became increasingly burdensome, Nasser began to ease state control over the private sector, encouraging state-owned bank loans to private business and introducing incentives to increase exports. During the 60's, the Egyptian economy went from sluggishness to the verge of collapse, the society became less free, and Nasser's appeal waned considerably." Answer:

A: government debt became increasingly burdensome

Problem: Given the question: Question: "Why did the band sign with John Reid?" Context: "In 1975, the band left for a world tour with each member in Zandra Rhodes-created costumes and accompanied with banks of lights and effects. They toured the US as headliners, and played in Canada for the first time. In September, after an acromonious split with Trident, the band negotiated themselves out of their Trident Studios contract and searched for new management. One of the options they considered was an offer from Led Zeppelin's manager, Peter Grant. Grant wanted them to sign with Led Zeppelin's own production company, Swan Song Records. The band found the contract unacceptable and instead contacted Elton John's manager, John Reid, who accepted the position." Answer:
++++++++++++++++++++++++++++++++
The answer is:
an acromonious split with Trident

input question: Question: "What's the lowest frame rate given for 1080i?" Context: "Non-cinematic HDTV video recordings intended for broadcast are typically recorded either in 720p or 1080i format as determined by the broadcaster. 720p is commonly used for Internet distribution of high-definition video, because most computer monitors operate in progressive-scan mode. 720p also imposes less strenuous storage and decoding requirements compared to both 1080i and 1080p. 1080p/24, 1080i/30, 1080i/25, and 720p/30 is most often used on Blu-ray Disc." Answer:???
output answer: 25

Question: "365 days, or sometimes 366 days make up what used to describe the passage of time for the Earth to revolve around the sun?" Context: "Information had been kept on digital tape for five years, with Kahle occasionally allowing researchers and scientists to tap into the clunky database. When the archive reached its fifth anniversary, it was unveiled and opened to the public in a ceremony at the University of California, Berkeley." Answer:
----
Answer: years

Q: Question: "What negative is there to adapting an antenna's impedance?" Context: "Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency)." Answer:
A:
loss of efficiency
