Canadian wheat farmers produced so much wheat over the last season that wheat prices plummeted. The government tried to boost wheat prices by offering farmers who agreed not to harvest 20 percent of their wheat field compensation up to a specified maximum per farm.The Canadian government's program, if successful, will not be a net burden on the budget. Which of the following, if true, is the best basis for an explanation of how this could be so?
By necessary, munitions plants hired many young woman during the war; at least as much as 500,00 and more others who had not any previous experience in factory work of any kind.
Take a very commonplace, often discussed and critical topic: Are we detecting a greenhouse effect, and related to this, is it exacerbated by "homogenic factors," i.e., human actions? Most would be inclined to give a positive answer to both of these questions. But, if pushed, what would be the evidence, and how well grounded would it be for such affirmations?Within scientific communities and associated scientifically informed circles, the answers have to be somewhat more ambiguous, particularly when rigorous questions concerning evidence are raised. Were scientific truth to be a matter of consensus, and some argue that scientific truth often turns out to be just that, then it is clear that there is beginning to be a kind of majority consensus among many earth science practitioners that the temperature of the Earth, particularly of the oceans, is indeed rising and that this is a crucial indicator for a possible greenhouse effect.Most of these scientists admit that the mean oceanic temperature has risen globally in the last several decades. But this generalization depends upon how accurate measurements may be, not just for samples, but also for the whole Earth. Hot spots, for example the now four year old hot spot near New Guinea which is part of the El Nio cycle, does not count by itself because it might be balanced by cold spots elsewhere. And the fact of the matter is that "whole earth measurements" are still rare and primitive in the simple sense that we simply do not have enough thermometers out. Secondly, even if we had enough thermometers, a simply synchronic whole earth measurement over three decades is but a blip in the diachronic history of ice age cycles over the last tens of thousands of years. Thirdly, even if we know that the earth is now heating up, has an ever increasing ozone hole, and from this strange weather effects can be predicted, how much of this is due to homogenic factors, such as CFCs, CO2 increases, hydrocarbon burning, and the like? Is it really the case, as Science magazine claimed in l990, "24% of greenhouse encouraging gases are of homogenic origin"?The authors claim that, a simply synchronic whole earth measurement over three decades is but a blip in the diachronic history of ice age cycles over the last tens of thousands of years would be strengthened if the author
Eclampsia in pregnancy is especially prevalent among women who are seriously malnourished. In order to achieve early detection of eclampsia in these individuals, public health officials distributed pamphlets explaining the importance of early detection of this potentially fatal disease.Which of the following, if true, is the best criticism of the use of the pamphlet as a method of achieving the public health officials goal?
The expansion of the influence of the Gregorian calendar system in non-European regions can be traced from European colonies such as India and Egypt, and the independent countries, replacing traditional calendars at least for official purposes.
Unemployment in Winston County has risen only 4% since I took office. Under my predecessor, unemployment rose 14%. Clearly, my economic policies are far more effective.Which of the following must be true in order for this argument to be valid?
