Question: Question: "Which of the following is not part of the antenna system: radio, interface or free space?" Context: "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:
Answer: interface

Question: Question: "What kind of name is Hayastantsis?" 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:
Answer: born and raised in Armenia

Question: Question: "Which is not taxed at 7%, food or dietary supplements?" Context: "The Tennessee income tax does not apply to salaries and wages, but most income from stock, bonds and notes receivable is taxable. All taxable dividends and interest which exceed the $1,250 single exemption or the $2,500 joint exemption are taxable at the rate of 6%. The state's sales and use tax rate for most items is 7%. Food is taxed at a lower rate of 5.25%, but candy, dietary supplements and prepared food are taxed at the full 7% rate. Local sales taxes are collected in most jurisdictions, at rates varying from 1.5% to 2.75%, bringing the total sales tax to between 8.5% and 9.75%, one of the highest levels in the nation. Intangible property is assessed on the shares of stock of stockholders of any loan company, investment company, insurance company or for-profit cemetery companies. The assessment ratio is 40% of the value multiplied by the tax rate for the jurisdiction. Tennessee imposes an inheritance tax on decedents' estates that exceed maximum single exemption limits ($1,000,000 for deaths in 2006 and thereafter)." Answer:
Answer:
Food
