Answer:D. that industrialism would increase food production
Explanation: Thomas Malthus, an economist and demographer, is known for his theory of population growth. However, he failed to take into account the potential for technological advancements and industrialization to increase food production. Malthus predicted that population growth would outpace food production, leading to widespread famine and misery. However, the Industrial Revolution and subsequent technological advancements in agriculture allowed for increased food production, which helped sustain growing populations. Malthus did not anticipate the transformative impact of industrialism on food production and underestimated humanity's ability to innovate and adapt to meet the needs of a growing population.
