[Q]: Question: "What does the gain represent?" Context: "Antennas are characterized by a number of performance measures which a user would be concerned with in selecting or designing an antenna for a particular application. Chief among these relate to the directional characteristics (as depicted in the antenna's radiation pattern) and the resulting gain. Even in omnidirectional (or weakly directional) antennas, the gain can often be increased by concentrating more of its power in the horizontal directions, sacrificing power radiated toward the sky and ground. The antenna's power gain (or simply "gain") also takes into account the antenna's efficiency, and is often the primary figure of merit." Answer:
****
[A]: merit

[Q]: Question: "Who was the biggest threat to the Ming, Khorchin Mongol or Nurhachi?" Context: "Relocating his court from Jianzhou to Liaodong provided Nurhachi access to more resources; it also brought him in close contact with the Khorchin Mongol domains on the plains of Mongolia. Although by this time the once-united Mongol nation had long since fragmented into individual and hostile tribes, these tribes still presented a serious security threat to the Ming borders. Nurhachi's policy towards the Khorchins was to seek their friendship and cooperation against the Ming, securing his western border from a powerful potential enemy." Answer:
****
[A]: Nurhachi

[Q]: Question: "How did the Estonians get part of their verbage?" Context: "Although the Estonian and Germanic languages are of very different origins, one can identify many similar words in Estonian and English, for example. This is primarily because the Estonian language has borrowed nearly one third of its vocabulary from Germanic languages, mainly from Low Saxon (Middle Low German) during the period of German rule, and High German (including standard German). The percentage of Low Saxon and High German loanwords can be estimated at 2225 percent, with Low Saxon making up about 15 percent.[citation needed]" Answer:
