Which of the following best explains why, in the late eighteenth and early nineteenth centuries, Thomas Malthus proposed his population theory? A- Malthus theorized that, if left unchecked by regular cycles of famine and misery, population would increase beyond the ability to feed itself. B- Malthus theorized the only way to prevent overpopulation would be to create policies that would limit the number of children a family could have. C- Malthus theorized that agricultural developments in the mid-to-late eighteenth century would result in a significant expansion of food production, therefore alleviating the threat of overpopulation. D- Malthus theorized that reductions of infant mortality would eventually result in slower population growth rates. E- Malthus theorized that the ability of a population to feed itself would increase with the expansion of the population; more people would mean greater knowledge invested in expanding food production.
