Extract the answer to the question from the following context. Question: The temperament that was not used, was considered to be of what balance? Context: The theories surrounding equal temperament began to be put in wider practice, especially as it enabled a wider range of chromatic possibilities in hard-to-tune keyboard instruments. Although Bach did not use equal temperament, as a modern piano is generally tuned, changes in the temperaments from the meantone system, common at the time, to various temperaments that made modulation between all keys musically acceptable, made possible Bach's Well-Tempered Clavier.
Ans: equal

Extract the answer to the question from the following context. Question: Zinc is added to pesticides by way of? Context: Zinc deficiency is crop plants' most common micronutrient deficiency; it is particularly common in high-pH soils. Zinc-deficient soil is cultivated in the cropland of about half of Turkey and India, a third of China, and most of Western Australia, and substantial responses to zinc fertilization have been reported in these areas. Plants that grow in soils that are zinc-deficient are more susceptible to disease. Zinc is primarily added to the soil through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces. Excess zinc is toxic to plants, although zinc toxicity is far less widespread.
Ans: humans

Extract the answer to the question from the following context. Question: What can change the wavelength? Context: For example, at 30 MHz (10 m wavelength) a true resonant 1⁄4-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.
Ans: resulting resistive impedance

Extract the answer to the question from the following context. Question: Which country did NOT get invaded? Context: In 2008 the Government of Canada made efforts, through the Canada First Defence Strategy, to modernize the Canadian Armed Forces, through the purchase of new equipment, improved training and readiness, as well as the establishment of the Canadian Special Operations Regiment. More funds were also put towards recruitment, which had been dwindling throughout the 1980s and '90s, possibly because the Canadian populace had come to perceive the CAF as peacekeepers rather than as soldiers, as shown in a 2008 survey conducted for the Department of National Defence. The poll found that nearly two thirds of Canadians agreed with the country's participation in the invasion of Afghanistan, and that the military should be stronger, but also that the purpose of the forces should be different, such as more focused on responding to natural disasters. Then CDS, Walter Natynczyk, said later that year that while recruiting has become more successful, the CF was facing a problem with its rate of loss of existing members, which increased between 2006 and 2008 from 6% to 9.2% annually.
Ans: Canada
