Twenty Questions is a monthly competition by Questions Unlimited where teams can qualify for the National Academic Championship. As the name suggests, each month teams attempt to answer 20 visual questions posted on the Questions Unlimited website. Teams that achieve or tie the highest score qualify for the NAC.
The questions are very much in the Chip Beall vein, asking about breeds of dogs and the metal used in the Vince Lombardi trophy. Perhaps by design, the images on the website do not have their names changed from where Chip took from. Thus, most answers can be quickly found by just Google Image Searching for the name of the image.
