Thomas malthus theory on population growth and david ricardo's views on wages both agreed

Thomas Malthus Theory of Population Growth and David Richardo's views on wages both agreed that food production increases as population increases, however, that the increase in population will overwhelm the abundance of food, and thus lead to diminishing returns. Both men believed in the principle of political economy. Both argued that there was a need to control the population in a time of abundance. They believed that if the population is not well managed, the abundance may be misused, and thus, the increased population will bear the brunt of the mismanagement.

no statements but ok.

the statement that best describes the idea of manifest destiny that was used in the 19th century would be that "it was fate that the united states would continue to  expand westward," since people thought the us was "destined" to do so.
