Ready?

First, Greenland is a semi-autonomous territory of what country?

The answer?

Denmark.

Its capital city is?

Nuuk.

Okay, number three.

Greenland's entire population is roughly the same size as which of these U.S.

cities?

San Francisco, Portland, Maine, or Omaha, Nebraska?

The answer, there are only about 58,000 people in Greenland.

That is just a little bit less than Portland, Maine.

And last question, it is a toughie.

Because there is so little vegetation on the island, historically, Greenlanders got a lot of their vitamin C from what?

The answer, whale skin, which apparently is a very rich source of the vitamin.

Next up, speaking of getting your vitamins, this week, health officials rolled out new dietary guidelines, including a revamped food pyramid.

And Dr. Mehmet Oz, who serves in the administration, talked up some of the other updated health advice, saying it was in keeping with places that are famous for long lifespans.

What food or beverage was he talking about?

The new federal guidance on drinking says people should limit their alcohol consumption, though it no longer lists specific amounts.

And last question for you.
