Insufficient rain can cause crops to falter and agricultural prices to rise. Records indicate that during a certain nation' s recent crisis, faltering crops and rising agricultural prices prompted the government to take over food distribution in an effort to prevent starvation. Thus, the weather must have played an important role in bringing about the crisis. The argument's reasoning is most vulnerable to criticism on the grounds that the argument ['infers, merely from the fact that one event could have caused a second event, that the first event in fact caused the second', 'uses the term "crisis" equivocally in the reasoning, referring to both a political crisis and an economic crisis', "concludes, merely from the fact that the period of insufficient rain occurred before the nation's crisis, that insufficient rain caused the nation's crisis", "fails to take into account the possibility that the scarcity was not severe enough to justify the government's taking over food distribution"]
