Each question will give the geographical coordinates (latitude and longitude) of a major world city, so major in fact that the cities will be the top ten 2005 population centers of the world (see my Population Quiz). Your job will be to visualize the globe and pick the city out of the four choices. The first world city is located at 118 degrees west longitude and 34 degrees north latitude.

Los Angeles. Los Angeles is eighth in population of the top ten (17 million).

If you used a globe or world map for the first question, you certainly got it right. You also got the idea that the quiz will be more fun without them. The next world city is located at 73 degrees east longitude and 19 degrees north latitude.

Bombay. Bombay, or Mumbai, is sixth in population (19 million).

Which major metropolitan area is found at 135 degrees east longitude and 35 degrees north latitude? Coordinates are rounded off, though many of these large cities span over a degree.

Osaka. Osaka is tenth in population (16 million).

Our fourth city is located at 47 degrees west longitude and 24 degrees south latitude. Which is it?

Sao Paulo. Sao Paulo is one of only two Southern Hemisphere cities in the top ten (20 million).

This city is to be found at 107 degrees east longitude and 6 degrees south latitude.

Jakarta. Jakarta is the other southern city (16 million).

This agglomeration, or greater metropolitan area, is at 77 degrees east longitude and 29 degrees north latitude.

Delhi. Delhi is seventh on the population list (19 million).

This city is to be found by going 140 degrees east of Greenwich and 36 north of the equator; i.e., 140 degrees east longitude and 36 degrees north latitude.

Tokyo. Tokyo is number one on the 2005 population chart, with a whopping 34 million people.

West of the prime meridian and in the tropics, this city is 99 degrees west longitude and 19 degrees north latitude.

Mexico City. Also the highest city on the list, Mexico City boasts over 22 million inhabitants.

If you want to make it here, go to 74 degrees west longitude and 41 degrees north latitude.

New York. Okay, Chicago was a ringer, since it is not in the top ten. New York is the farthest north of the big ones, has over 21 million people and, as Old Blue Eyes told us, "If you can make it here, you can make it anywhere."

The last major city is on the 37th parallel and 127 degrees east of Greenwich (127 degrees east longitude and 37 degrees north latitude).

Seoul. Seoul lies just south of the famous Korean DMZ at the 38th parallel and is third in population (22 million).
