Today's Geo Quiz sends us in search of Spain's longest river.

It rises in the Cantabrian Mountains. It then flows 565 miles into the Mediterranean Sea, between Barcelona and Valencia. Along the way, this river bisects a town that a UN report ranks number two in the world for per capita cocaine consumption.

Sorry...we can't tell you the name of the town. It includes the name of the river. But we'll tell you why researchers think the town that the river runs through is Europe's cocaine capital today's Geo Answer.

A small, private island called Leaf Cay went on the auction block today. Starting price, twelve-million dollars.

A Florida based millionaire is selling Leaf Cay along with the island's contents. They include: nineteen buildings, an airstrip, and a five year's supply of emergency food. That's a lot of food, but it could come in handy for the new owners. It's not uncommon for hurricanes to strike this area. Leaf Cay is one of 700 islands in a chain that divides the Atlantic and Caribbean oceans.

For today's Geo Quiz we want you to name this tropical paradise. The world's third longest barrier reef is found here, and divers come from all over to explore it.

Today's Geo Quiz takes us to New York, New York.

New York City has five boroughs. We're looking for one in particular. Here are three hints.

Number one.

The two-point-two million people here make it New York's second most populous borough.

Your second hint...

If you fly into New York City, you're almost certainly going to land in this borough.

It's the home of John F. Kennedy and LaGuardia airports.

And hint number three.

This borough is the most ethnically diverse county in the United States. Nearly half of its residents are immigrants.We'll hear some of the hot music this melting pot has produced when we answer today's Geo Quiz.

Today's geo quiz takes us just south of the Equator.

It's pretty warm in the country we're looking for. It's warm enough that it may come as a surprise to learn that penguins live along the coast. But here's the real surprise. It turns out that penguins were here tens of millions of years earlier than previously thought.

Scientists this week described the fossils of previously unknown types of penguins found in this country. We'll hear more about some mighty big birds in today's answer.

First, here are a couple more hints:

This country became independent of Spain in 1824. And its border with Bolivia runs through Lake Titicaca. That's the highest navigable lake in the world.

For today's Geo Quiz, we're heading to a county in England with some odd boasting rights. It's where the world's first military tank was designed and built. It's known for its ancient Roman structures, grand Elizabethan architecture, and vast parkland. And it's the setting for scenes in the films Pride and Prejudice and Raiders of the Lost Ark.

Now this county wedged between Norfolk and Yorkshire has another claim to fame. It's the site of an unusual international sports competition that can bruise and slime players, and at the same time provide them with a little sustenance. Organizers of this event say the sport has been played since ancient times, and that millions of players enjoy it worldwide. We'd like you to name the county and the sport that's keeping it on the map.

Here's another clue...the answer's coming up in the time it takes to make a soft-boiled egg.

Twist-off...or cork? That's the question for today's Geo Quiz.

Portugal produces roughly half of the world's supply of natural cork. The stuff is so highly prized that under Portuguese law it's illegal to cut down a cork oak tree. Natural cork has been used to seal wine bottles for centuries.

But, alas, times change. Now many wine bottle come with synthetic corks -- or even metal twist-off caps. We want you to name a country where the twist-off is king. This is the country that launched the "Screwcap Wine Seal Initiative" a few years back.

Now, an estimated 90% of home-grown wine bottles are sealed with a screwcap. This country in the southern hemisphere has abundant natural beauty. Much of its landscape was on display in the "Lord of the Rings" movies.

So, here's a toast..

....may you be able to name that country.

For today's geo quiz....follow the equator.

Head just a few degrees north of the equator along the western coast of Africa to find the country we're looking for.

Its capital, Accra is right there on the Atlantic coast. Accra is a city of 2 million. It used to be a European trading post for gold and later, slaves. Nowadays, the country's chief export is Cocoa.

This west African country is the world's 2nd largest producer of cocoa. But while it's exporting fine cocoa, it's importing something else. Bicycles. Thousands of them that are destined for the countryside.

We' ll tell you more about those bicycles in the answer...but first try and name this West African nation.

Today's Geo Quiz is a breeze... if you know your architecture.

The city we're looking for is home to La Sagrada Família. That's the still unfinished basilica designed by Antoni Gaudí. Then there's the Palace of Catalan Music. Both are considered architectural jewels and UNESCO World Heritage Sites.

Today this city has a vibrant musical scene. In our Global Hit, I'll tell you about a local band that's known for its blend of hip hop and flamenco.

The city is located along Spain's Mediterranean Coast less than a hundred miles from the French border.

Residents of this city are currently enjoying a new transportation option. They call it "bicing." The city has a fleet of bicycles that locals can borrow to get around.

We'll tell you about more about that in today's answer.

The "island of the bearded ones" is our goal for today's Geo Quiz. This island sits just east of the Lesser Antilles.

Technically, it's surrounded by the waters of the western Atlantic Ocean. But the island is commonly referred to as the "eastern-most island of the Caribbean."

The earliest inhabitants may have arrived on paddle canoes from South America. Then came Portuguese and Spanish explorers who gave the island its modern name. That name may be a reference to the island's bearded fig trees.

The Barbadoes Mulatto Girl: an engraving published at London in 1779, after a c. 1764 painting by Agostino Brunias.

In the 17th century, this island became an English colony. The English sent Scottish and Irish laborers and slaves to the island to work on plantations. Later, African slaves were brought in as well. The place remained an English colony until independence in 1966.

Today it's a major tourist destination, thanks in part to its beautiful coral reefs. Name the island, and we'll tell you more about its connection to Irish history in today's Global Hit!

Today's Geo Quiz is about an obsession.

The French master Claude Monet wrote in 1908 that "landscape of water and reflections have become an obsession for me." At the time Monet was busy painting water lilies in his garden 50 miles outside of Paris.

We're looking for the name of the village that's home to what is now perhaps the world's most famous water lily pond. Monet's garden was in a village near the banks of the Seine River. It's located on the border between the French province of Normandy and the ÃŽle-de-France.

It's there that Monet's created some of his most famous paintings of water lilies.

Nowadays you can find many of these spectacular paintings known as the Les Nympheas in Paris at the Orangerie Gallery.

On very rare occasions, Monet's water lilies come up for auction. Tomorrow, a Monet water Lilly is expected to fetch 30 million dollars or more. It hasn't been seen in public for 70 years. Some art dealers predict its sale will to set a record for a Monet painting.

We're not bidding. We just want to know the village where the lily pond is located.
