Example Question #31 : Geography

Population has grown most dramatically in which of these centuries? 

Possible Answers:

The nineteenth century

The sixteenth century

The twentieth century

The seventeenth century

The eighteenth century

Correct answer:

The twentieth century

Explanation:

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 #32 : Geography

In which of these continents is the population the highest? 

Possible Answers:

North America

Asia

Africa

Europe

South America

Correct answer:

Asia

Explanation:

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 #33 : Geography

Which of these is the correct order of continents by population (from highest to lowest)? 

Possible Answers:

North America; South America; Africa; Asia; Europe

Africa; Europe; Asia; North America; South America

Asia; North America; Europe; Africa; South America

Africa; Asia; North America; Europe; South America

Asia; Africa; Europe; North America; South America

Correct answer:

Asia; Africa; Europe; North America; South America

Explanation:

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.
