Input: Read this: To improve the efficiency of the lamp, the filament usually consists of multiple coils of coiled fine wire, also known as a 'coiled coil'. For a 60-watt 120-volt lamp, the uncoiled length of the tungsten filament is usually 22.8 inches (580 mm), and the filament diameter is 0.0018 inches (0.046 mm). The advantage of the coiled coil is that evaporation of the tungsten filament is at the rate of a tungsten cylinder having a diameter equal to that of the coiled coil. The coiled-coil filament evaporates more slowly than a straight filament of the same surface area and light-emitting power. As a result, the filament can then run hotter, which results in a more efficient light source, while reducing the evaporation so that the filament will last longer than a straight filament at the same temperature.
Question: What is the advantage of a coiled-coil filament over a straight filament?

Output: The coiled-coil filament evaporates more slowly

Input: Read this: Bell and his partners, Hubbard and Sanders, offered to sell the patent outright to Western Union for $100,000. The president of Western Union balked, countering that the telephone was nothing but a toy. Two years later, he told colleagues that if he could get the patent for $25 million he would consider it a bargain. By then, the Bell company no longer wanted to sell the patent. Bell's investors would become millionaires, while he fared well from residuals and at one point had assets of nearly one million dollars.
Question: How much the the President of Western Union want to pay for the patent later on?

Output: $25 million

Input: Read this: Analog tape recorders with bandwidth capable of recording analog HD signals, such as W-VHS recorders, are no longer produced for the consumer market and are both expensive and scarce in the secondary market.
Question: What kind of recorder is no longer produced for the consumer market?

Output: Analog tape

Input: Read this: New York City has over 28,000 acres (110 km2) of municipal parkland and 14 miles (23 km) of public beaches. Parks in New York City include Central Park, Prospect Park, Flushing MeadowsCorona Park, Forest Park, and Washington Square Park. The largest municipal park in the city is Pelham Bay Park with 2,700 acres (1,093 ha).
Question: How long are all the public beaches together in miles?

Output:
