Problem: Sexual orientation:

In response to the criticism of the Kinsey scale only measuring two dimensions of sexual orientation, Fritz Klein developed the Klein sexual orientation grid (KSOG), a multidimensional scale for describing sexual orientation. Introduced in Klein's book The Bisexual Option, the KSOG uses a 7-point scale to assess seven different dimensions of sexuality at three different points in an individual's life: past (from early adolescence up to one year ago), present (within the last 12 months), and ideal (what would you choose if it were completely your choice).

Who invented the KSOG?

A: Fritz Klein


Problem: Space Race:

By 1959, American observers believed that the Soviet Union would be the first to get a human into space, because of the time needed to prepare for Mercury's first launch. On April 12, 1961, the USSR surprised the world again by launching Yuri Gagarin into a single orbit around the Earth in a craft they called Vostok 1. They dubbed Gagarin the first cosmonaut, roughly translated from Russian and Greek as "sailor of the universe". Although he had the ability to take over manual control of his spacecraft in an emergency by opening an envelope he had in the cabin that contained a code that could be typed into the computer, it was flown in an automatic mode as a precaution; medical science at that time did not know what would happen to a human in the weightlessness of space. Vostok 1 orbited the Earth for 108 minutes and made its reentry over the Soviet Union, with Gagarin ejecting from the spacecraft at 7,000 meters (23,000 ft), and landing by parachute. The Fédération Aéronautique Internationale (International Federation of Aeronautics) credited Gagarin with the world's first human space flight, although their qualifying rules for aeronautical records at the time required pilots to take off and land with their craft. For this reason, the Soviet Union omitted from their FAI submission the fact that Gagarin did not land with his capsule. When the FAI filing for Gherman Titov's second Vostok flight in August 1961 disclosed the ejection landing technique, the FAI committee decided to investigate, and concluded that the technological accomplishment of human spaceflight lay in the safe launch, orbiting, and return, rather than the manner of landing, and so revised their rules accordingly, keeping Gagarin's and Titov's records intact.

Which country succesfully launched the first person into space in 1961?

A: the USSR


Problem: Oklahoma:

During a 10-day run in Oklahoma City, the State Fair of Oklahoma attracts roughly one million people along with the annual Festival of the Arts. Large national pow-wows, various Latin and Asian heritage festivals, and cultural festivals such as the Juneteenth celebrations are held in Oklahoma City each year. The Tulsa State Fair attracts over one million people during its 10-day run, and the city's Mayfest festival entertained more than 375,000 people in four days during 2007. In 2006, Tulsa's Oktoberfest was named one of the top 10 in the world by USA Today and one of the top German food festivals in the nation by Bon Appetit magazine.

How many people attend the Tulsa State Fair each year?
---
A: over one million


Problem: Compact disc:

Replicated CDs are mass-produced initially using a hydraulic press. Small granules of heated raw polycarbonate plastic are fed into the press. A screw forces the liquefied plastic into the mold cavity. The mold closes with a metal stamper in contact with the disc surface. The plastic is allowed to cool and harden. Once opened, the disc substrate is removed from the mold by a robotic arm, and a 15 mm diameter center hole (called a stacking ring) is created. The time it takes to "stamp" one CD is usually two to three seconds.

What closes the mold?
