Which of these regions possesses both a high arithmetic and a high physiologic density? which of these regions possesses both a high arithmetic and a high physiologic density? africa australia north america asia south america?

I would say that Asia should be the answer as for example the populations of India and China are both greater than 1.3 billion people so that is the arithmetic figure plus a correlative physiologic density or number of people/unit area of arable land is also very likely in these two countries alone. With high figures for physiologic density, then it means they may reach their output limit sooner than a country with a lower such density.
