[Q]: Given the following passage "For example, at 30 MHz (10 m wavelength) a true resonant 14-wavelength monopole would be almost 2.5 meters long, and using an antenna only 1.5 meters tall would require the addition of a loading coil. Then it may be said that the coil has lengthened the antenna to achieve an electrical length of 2.5 meters. However, the resulting resistive impedance achieved will be quite a bit lower than the impedance of a resonant monopole, likely requiring further impedance matching. In addition to a lower radiation resistance, the reactance becomes higher as the antenna size is reduced, and the resonant circuit formed by the antenna and the tuning coil has a Q factor that rises and eventually causes the bandwidth of the antenna to be inadequate for the signal being transmitted. This is the major factor that sets the size of antennas at 1 MHz and lower frequencies.", answer the following question. Note that the answer is present within the text. Question: Why does the antenna load fail?
****
[A]: a Q factor that rises

[Q]: Given the following passage "The Germans developed massive reinforced concrete blockhouses, some more than six stories high, which were known as Hochbunker "High Bunkers" or "Flakturme" flak towers, on which they placed anti-aircraft artillery. Those in cities attacked by the Allied land forces became fortresses. Several in Berlin were some of the last buildings to fall to the Soviets during the Battle of Berlin in 1945. The British built structures such as the Maunsell Forts in the North Sea, the Thames Estuary and other tidal areas upon which they based guns. After the war most were left to rot. Some were outside territorial waters, and had a second life in the 1960s as platforms for pirate radio stations.", answer the following question. Note that the answer is present within the text. Question: Where were Maunsell Forts located
****
[A]: in the North Sea, the Thames Estuary and other tidal areas

[Q]: Given the following passage "The just-noticeable difference (jnd) (the threshold at which a change is perceived) depends on the tone's frequency content. Below 500 Hz, the jnd is about 3 Hz for sine waves, and 1 Hz for complex tones; above 1000 Hz, the jnd for sine waves is about 0.6% (about 10 cents). The jnd is typically tested by playing two tones in quick succession with the listener asked if there was a difference in their pitches. The jnd becomes smaller if the two tones are played simultaneously as the listener is then able to discern beat frequencies. The total number of perceptible pitch steps in the range of human hearing is about 1,400; the total number of notes in the equal-tempered scale, from 16 to 16,000 Hz, is 120.", answer the following question. Note that the answer is present within the text. Question: Who determines if a change in pitch exists?
****
[A]: the listener

[Q]: Given the following passage "Slavic standard languages which are official in at least one country: Belarusian, Bosnian, Bulgarian, Croatian, Czech, Macedonian, Montenegrin, Polish, Russian, Serbian, Slovak, Slovene, and Ukrainian. The alphabet depends on what religion is usual for the respective Slavic ethnic groups. The Orthodox use the Cyrillic alphabet and the Roman Catholics use Latin alphabet, the Bosniaks who are Muslims also use the Latin. Few Greek Roman and Roman Catholics use the Cyrillic alphabet however. The Serbian language and Montenegrin language uses both Cyrillic and Latin alphabets. There is also a Latin script to write in Belarusian, called the Lacinka alphabet.", answer the following question. Note that the answer is present within the text. Question: If a Slavic person who speaks Serbian is not writing in Latin, what is the alphabet they are likely using?
****
[A]:
Cyrillic
