Q: Extract the answer to the question from the following context. Question: What are viruses? Context: Persistent infections occur because the body is unable to clear the organism after the initial infection. Persistent infections are characterized by the continual presence of the infectious organism, often as latent infection with occasional recurrent relapses of active infection. There are some viruses that can maintain a persistent infection by infecting different cells of the body. Some viruses once acquired never leave the body. A typical example is the herpes virus, which tends to hide in nerves and become reactivated when specific circumstances arise.
A: organism
Question: Extract the answer to the question from the following context. Question: Why did Kaplan give the microphone to Tucker? Context: Myers spoke next and continued to read the script. Once it was West's turn to speak again, he said, "George Bush doesn't care about black people." At this point, telethon producer Rick Kaplan cut off the microphone and then cut away to Chris Tucker, who was unaware of the cut for a few seconds. Still, West's comment reached much of the United States.
Answer: Once it was West's turn to speak again, he said, "George Bush doesn't care about black people."
[Q]: Extract the answer to the question from the following context. Question: what group is mentioned first? Context: The events of the summer of 1974 dominate the politics on the island, as well as Greco-Turkish relations. Around 150,000 settlers from Turkey are believed to be living in the northmany of whom were forced from Turkey by the Turkish governmentin violation of the Geneva Convention and various UN resolutions. Following the invasion and the capture of its northern territory by Turkish troops, the Republic of Cyprus announced that all of its ports of entry in the north were closed, as they were effectively not under its control.[citation needed]
****
[A]: 150,000 settlers
input: Please answer the following: Extract the answer to the question from the following context. Question: What happened in the fifth decade of the century? Context: The Somali flag is an ethnic flag conceived to represent ethnic Somalis. It was created in 1954 by the Somali scholar Mohammed Awale Liban, after he had been selected by the labour trade union of the Trust Territory of Somalia to come up with a design. Upon independence in 1960, the flag was adopted as the national flag of the nascent Somali Republic. The five-pointed Star of Unity in the flag's center represents the Somali ethnic group inhabiting the five territories in Greater Somalia.

Please answer this: Extract the answer to the question from the following context. Question: The overhead wire method of powering streetcars was more unsightly than the conduit slot method, but it eventually overtook the slot method because it didn't have what downfalls? Context: Some street trams (streetcars) used conduit third-rail current collection. The third rail was below street level. The tram picked up the current through a plough (U.S. "plow") accessed through a narrow slot in the road. In the United States, much (though not all) of the former streetcar system in Washington, D.C. (discontinued in 1962) was operated in this manner to avoid the unsightly wires and poles associated with electric traction. The same was true with Manhattan's former streetcar system. The evidence of this mode of running can still be seen on the track down the slope on the northern access to the abandoned Kingsway Tramway Subway in central London, United Kingdom, where the slot between the running rails is clearly visible, and on P and Q Streets west of Wisconsin Avenue in the Georgetown neighborhood of Washington DC, where the abandoned tracks have not been paved over. The slot can easily be confused with the similar looking slot for cable trams/cars (in some cases, the conduit slot was originally a cable slot). The disadvantage of conduit collection included much higher initial installation costs, higher maintenance costs, and problems with leaves and snow getting in the slot. For this reason, in Washington, D.C. cars on some lines converted to overhead wire on leaving the city center, a worker in a "plough pit" disconnecting the plough while another raised the trolley pole (hitherto hooked down to the roof) to the overhead wire. In New York City for the same reasons of cost and operating efficiency outside of Manhattan overhead wire was used. A similar system of changeover from conduit to overhead wire was also used on the London tramways, notably on the southern side; a typical changeover point was at Norwood, where the conduit snaked sideways from between the running rails, to provide a park for detached shoes or ploughs.

Answer: higher initial installation costs, higher maintenance costs, and problems with leaves and snow getting in the slot
Question: Extract the answer to the question from the following context. Question: What is the source of ions that are collected at the negative electrode in an ion gauge? 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:
gas molecules
