An increase in a country's physiological density would suggest an increase in the size of its population.
To determine the answer to this question, we need to understand what physiological density refers to. Physiological density is the number of people per unit of arable land, which is the land suitable for agriculture. So, to find the answer, we should consider what an increase in physiological density would indicate:
1. An increase in the amount of agricultural land: This does not necessarily relate to physiological density. If the amount of agricultural land increases, it may result in a decrease in physiological density as there is more land available per person.
2. A limit to the number of farmers: This is not directly related to physiological density. Though a limit to the number of farmers could impact agricultural productivity, it doesn't specifically address the number of people per unit of arable land.
3. An increase in the amount of irrigated land: This could potentially relate to physiological density. If the amount of irrigated land increases, it implies greater agricultural productivity and the ability for more people to be sustained per unit of arable land, leading to an increase in physiological density.
4. An increase in the size of its population: This is the most likely answer. When the population of a country increases and the amount of arable land remains constant, the number of people per unit of arable land, or the physiological density, also increases.
5. A limit to the number of farm animals: This factor is not directly related to physiological density, as it pertains to animals rather than human population.
Therefore, the correct answer is "An increase in the size of its population."
