Question 3 (1 point) If the physiological density in a given country is very high and its arithmetic density is very low, then a country has: a a larger number of farmers, although the number of farmers is not a great as the number of people living in the cities b 100 few farmers for the large area of land suitable for agniculture c a small percentage of land sutable for agriculture, even if there seems to be plenty of space available to live in d inefficient farmers or farmers that are out of work Question 4 (1 point) An Irea has: 1,000 people 300 farmers 200 total \( \mathrm{sq} . \mathrm{mi} \) 30 sq.mi. of arable land Calculate the agricultural density a \( \quad 5 / \mathrm{sq} . \mathrm{ml} \). b \( \quad 33.33 / \mathrm{sq} . \mathrm{ml} \). C \( \quad 10 / \mathrm{sq} \mathrm{ml} \) d \( \quad 1.5 / \mathrm{sq} . \mathrm{mi} \)

High physiological density combined with low arithmetic density typically indicates that the majority of the population lives in urban areas, while agricultural land is limited. This means that the country may have a small percentage of land that's suitable for agriculture, which is further emphasized by the low arithmetic density. It creates a situation where the economy relies heavily on urban activities and industry rather than agriculture, often leading to increased food imports. To calculate agricultural density, you divide the number of farmers by the amount of arable land in square miles. In this scenario: 300 farmers / 30 sq.mi. of arable land = 10 farmers per sq.mi. This means the correct answer is (C) 10 / sq.mi. Knowing how to calculate agricultural density can give insights into the agricultural sustainability of any given area!
