Answer:
Chicago, the birthplace of the skyscraper, started to build upwards in 1871 after the great fire. These buildings consisted of ten to twelve storeys and differed in the way they were built from other buildings. Conventional buildings have walls which support the building’s weight, whereas skyscrapers have walls that are thin and light and attached to a metal frame. If skyscrapers were built following conventional methods, they would be unattractive buildings with thick walls and small windows. The development of this alternative method of building a skyscraper, using a metal frame, meant that literally the sky was the limit as to how many floors a building could have. Having skyscrapers that went above seven floors depended mainly on the development of the lift. Without Elisha Otis’s design for the electrical lift, skyscrapers would not have continued to develop as they did. Various other methods of moving a lift had been tried before but they were all unsuitable for very tall buildings. One problem that had to be solved was how to keep people warm in winter. Steam heating using radiators was the answer to this problem, and the introduction of electrical lighting and the telephone provided the final touches to ensure that skyscrapers were firmly established. They are so much a feature of most cities’ skylines today, that it would be hard to imagine life without them.

Sure, here's the passage with the blanks filled in:
Sky High
Chicago, the birthplace of the skyscraper, started to build upwards in 1871 after the great fire. Early buildings consisted of ten to twelve storeys and differed in the way they were built from other buildings. Conventional buildings have walls which support the building's weight, whereas skyscrapers have walls that are thin and light and attached to a metal frame. If skyscrapers were built following conventional methods, they would be unattractive buildings with thick walls and small windows. The development of this alternative method of building a skyscraper, using a metal frame, meant that literally the sky was the limit as to how many floors a building could have. Having skyscrapers that went above seven floors depended mainly on the development of the lift. Without Elisha Otis's design for the electrical lift, skyscrapers would not have continued to develop as they did. Various other methods of moving a lift had been tried before but they were all unsuitable for very tall buildings. One problem that had to be solved was how to keep people warm.
