Context: A climbing elevator is a self-ascending elevator with its own propulsion. The propulsion can be done by an electric or a combustion engine. Climbing elevators are used in guyed masts or towers, in order to make easy access to parts of these constructions, such as flight safety lamps for maintenance. An example would be the Moonlight towers in Austin, Texas, where the elevator holds only one person and equipment for maintenance. The Glasgow Tower an observation tower in Glasgow, Scotland also makes use of two climbing elevators.

input: Please answer the following: Extract the answer to the question from the following context. Question: Money from what media outlet goes to teams? Context: The Premier League distributes a portion of its television revenue to clubs that are relegated from the league in the form of "parachute payments". Starting with the 201314 season, these payments are in excess of 60 million over four seasons. Though designed to help teams adjust to the loss of television revenues (the average Premier League team receives 55 million while the average Football League Championship club receives 2 million), critics maintain that the payments actually widen the gap between teams that have reached the Premier League and those that have not, leading to the common occurrence of teams "bouncing back" soon after their relegation. For some clubs who have failed to win immediate promotion back to the Premier League, financial problems, including in some cases administration or even liquidation have followed. Further relegations down the footballing ladder have ensued for several clubs unable to cope with the gap.

input: Please answer the following: Extract the answer to the question from the following context. Question: How did the Z2 work? Context: Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2, created by German engineer Konrad Zuse in 1939, was one of the earliest examples of an electromechanical relay computer.
