Question: One STOBAR carrier: Liaoning was originally built as the 57,000 tonne Soviet Admiral Kuznetsov-class carrier Varyag and was later purchased as a stripped hulk by China in 1998 on the pretext of use as a floating casino, then partially rebuilt and towed to China for completion. Liaoning was commissioned on 25 September 2012, and began service for testing and training. On 24 or 25 November 2012, Liaoning successfully launched and recovered several Shenyang J-15 jet fighter aircraft. She is classified as a training ship, intended to allow the navy to practice with carrier usage. On 26 December 2012, the People's Daily reported that it will take four to five years for Liaoning to reach full capacity, mainly due to training and coordination which will take significant amount of time for Chinese PLA Navy to complete as this is the first aircraft carrier in their possession. As it is a training ship, Liaoning is not assigned to any of China's operation fleets.
Try to answer this question if possible: What is the Liaoning intended to help the navy practice with?
Answer: carrier usage
Question: In a tumbling pass, dismount or vault, landing is the final phase, following take off and flight  This is a critical skill in terms of execution in competition scores, general performance, and injury occurrence. Without the necessary magnitude of energy dissipation during impact, the risk of sustaining injuries during somersaulting increases. These injuries commonly occur at the lower extremities such as: cartilage lesions, ligament tears, and bone bruises/fractures. To avoid such injuries, and to receive a high performance score, proper technique must be used by the gymnast. "The subsequent ground contact or impact landing phase must be achieved using a safe, aesthetic and well-executed double foot landing."  A successful landing in gymnastics is classified as soft, meaning the knee and hip joints are at greater than 63 degrees of flexion.
Try to answer this question if possible: Where do most injuries happen?
Answer: the lower extremities such as: cartilage lesions, ligament tears, and bone bruises/fractures
Question: The maximum distance at which a gun or missile can engage an aircraft is an important figure. However, many different definitions are used but unless the same definition is used, performance of different guns or missiles cannot be compared. For AA guns only the ascending part of the trajectory can be usefully used. One term is 'ceiling', maximum ceiling being the height a projectile would reach if fired vertically, not practically useful in itself as few AA guns are able to fire vertically, and maximum fuse duration may be too short, but potentially useful as a standard to compare different weapons.
Try to answer this question if possible: What is an important number when it comes to guns engaging an aircraft?
Answer: The maximum distance
Question: On August 9, 2015, ESPN reported that the New Orleans VooDoo and Las Vegas Outlaws had ceased operations, effective immediately, a claim which was subsequently validated on the AFL website. On September 1, 2015, the Spokane Shock officially left the AFL and joined the IFL under the new name Spokane Empire, becoming the fifth active AFL/af2 franchise to leave for the IFL since bankruptcy (Iowa Barnstormers, Tri-Cities Fever, Green Bay Blizzard and Arkansas Twisters—now the Texas Revolution—left previously).
