[Q]: Question: "What affects current in hot cathode gauges?" 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:
****
[A]: the number of ions, which depends on the pressure in the gauge

Frequently used vegetables include courgettes, green peppers, okra, green beans, artichokes, carrots, tomatoes, cucumbers, lettuce and grape leaves, and pulses such as beans, broad beans, peas, black-eyed beans, chick-peas and lentils. The most common fruits and nuts are pears, apples, grapes, oranges, mandarines, nectarines, medlar, blackberries, cherry, strawberries, figs, watermelon, melon, avocado, lemon, pistachio, almond, chestnut, walnut, and hazelnut."

[Q]: Question: "Where does the highway conclude?" Context: "St. John's is the eastern terminus of the Trans-Canada Highway, one of the longest national highways in the world. The divided highway, also known as "Outer Ring Road" in the city, runs just outside the main part of the city, with exits to Pitts Memorial Drive, Topsail Road, Team Gushue Highway, Thorburn Road, Allandale Road, Portugal Cove Road and Torbay Road, providing relatively easy access to neighbourhoods served by those streets. Pitts Memorial Drive runs from Conception Bay South, through the city of Mount Pearl and into downtown St. John's, with interchanges for Goulds, Water Street and Hamilton Avenue-New Gower Street." Answer:
****
[A]: St. John's

[Q]: Question: "what ethnicity is first mentioned?" Context: "Armenians have had a presence in the Armenian Highland for over four thousand years, since the time when Hayk, the legendary patriarch and founder of the first Armenian nation, led them to victory over Bel of Babylon. Today, with a population of 3.5 million, they not only constitute an overwhelming majority in Armenia, but also in the disputed region of Nagorno-Karabakh. Armenians in the diaspora informally refer to them as Hayastantsis (), meaning those that are from Armenia (that is, those born and raised in Armenia). They, as well as the Armenians of Iran and Russia speak the Eastern dialect of the Armenian language. The country itself is secular as a result of Soviet domination, but most of its citizens identify themselves as Apostolic Armenian Christian." Answer:
****
[A]:
Armenians
