Problem: Tracks include Tucson Raceway Park and Rillito Downs. Tucson Raceway Park hosts NASCAR-sanctioned auto racing events and is one of only two asphalt short tracks in Arizona. Rillito Downs is an in-town destination on weekends in January and February each year. This historic track held the first organized quarter horse races in the world, and they are still racing there. The racetrack is threatened by development. The Moltacqua racetrack, was another historic horse racetrack located on what is now Sabino Canyon Road and Vactor Ranch Trail, but it no longer exists.
How many asphalt short tracks are in Arizona?
The answer is the following: two

Problem: The U.S., UK, France, Italy and the majority of other Western countries considered the annexation of Estonia by the USSR illegal. They retained diplomatic relations with the representatives of the independent Republic of Estonia, never de jure recognised the existence of the Estonian SSR, and never recognised Estonia as a legal constituent part of the Soviet Union. Estonia's return to independence became possible as the Soviet Union faced internal regime challenges, loosening its hold on the outer empire. As the 1980s progressed, a movement for Estonian autonomy started. In the initial period of 19871989, this was partially for more economic independence, but as the Soviet Union weakened and it became increasingly obvious that nothing short of full independence would do, Estonia began a course towards self-determination.
What decade started the push for Estonian independence?
The answer is the following: 1980s

Problem: One person may presume knowledge of another person's sexual orientation based upon perceived characteristics, such as appearance, clothing, tone of voice, and accompaniment by and behavior with other people. The attempt to detect sexual orientation in social situations is known as gaydar; some studies have found that guesses based on face photos perform better than chance. 2015 research suggests that "gaydar" is an alternate label for using LGBT stereotypes to infer orientation, and that face-shape is not an accurate indication of orientation.
What did this research also show about face-shape?
The answer is the following: not an accurate indication of orientation.

Problem: Gymnasts sprint down a runway, which is a maximum of 25 meters in length, before hurdling onto a spring board. The gymnast is allowed to choose where they start on the runway. The body position is maintained while "punching" (blocking using only a shoulder movement) the vaulting platform. The gymnast then rotates to a standing position. In advanced gymnastics, multiple twists and somersaults may be added before landing. Successful vaults depend on the speed of the run, the length of the hurdle, the power the gymnast generates from the legs and shoulder girdle, the kinesthetic awareness in the air, and the speed of rotation in the case of more difficult and complex vaults.
What do successful vaults depend on other than speed of the run?
The answer is the following:
the length of the hurdle, the power the gymnast generates from the legs and shoulder girdle, the kinesthetic awareness in the air, and the speed of rotation
