Just list the countries that have won the Davis Cup since 1900! If you type in United States, it will pop up in the 32 years it won the title. Easy Peasy, right?! You have three minutes. Oh, and you have to list the country in its old name. For example, Russia will only turn up Russia. If the Soviet Union won it in the past, you have to type "Soviet Union". Good luck!
