Example Question #11 : Human Populations And Cultures
Population has grown most dramatically in which of these centuries?
The sixteenth century
The nineteenth century
The eighteenth century
The seventeenth century
The twentieth century
The twentieth century
Prior to the Industrial Revolution, the population of the world was less than one billion. It would pass one billion early in the nineteenth century, but would not reach two billion until early in the twentieth century. Since the massive improvements in public health, medicine, technology, and farming practices of the twentieth century, the world population has risen to over seven billion. So the correct answer is easily the twentieth century.
Example Question #12 : Human Populations And Cultures
In which of these continents is the population the highest?
South America
Africa
North America
Europe
Asia
Asia
More than half the people on the planet live in the continent of Asia: the majority of these living in China and India. Of the more than seven billion people on Earth, at least four billion live in Asia.
Example Question #13 : Human Populations And Cultures

Africa; Asia; North America; Europe; South America
Asia; North America; Europe; Africa; South America
North America; South America; Africa; Asia; Europe
Africa; Europe; Asia; North America; South America
Asia; Africa; Europe; North America; South America
Asia; Africa; Europe; North America; South America
More than half the people in the world live in Asia. After Asia, the next highest is Africa, which is the only other continent to have more than a billion people living there. After Africa comes Europe, then North America, then South America. The population of Europe is projected to remain approximately the same for several decades, so by the end of the twenty-first century it will have likely been overtaken by all the other continents, except Oceania and Antarctica.
