Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
American Industries adopted the Bessemer process, by purifying iron to make strong, lightweight, steel; this strong steel made possible new inventions and innovations in cities to solve urbanization challenges. ALL of the following are examples of innovations and inventions in cities that used this new steel EXCEPT what?
A
skyscrapers
B
suspension bridges
C
incandescent electric light bulbs
D
elevators
Explanation: 

Detailed explanation-1: -The Bessemer process allowed steel to be produced without fuel, using the impurities of the iron to create the necessary heat. This drastically reduced the costs of steel production, but raw materials with the required characteristics could be difficult to find.

Detailed explanation-2: -Overview. In 1856, Henry Bessemer (1813-1898) developed a new method for manufacturing steel. The Bessemer process made possible the manufacture of large amounts of high-quality steel for the first time. This, in turn, provided steel at relatively low cost to various industries.

Detailed explanation-3: -Kelly’s invention used chemical reactions to remove impurities in molten pig iron, a crude form of iron, and reduce the fuel requirements of the process. It was a key development that contributed to the vast expansion of the iron and steel industries around the turn of the 20th century.

Detailed explanation-4: -The Bessemer Process was the first inexpensive industrial process that allowed for the mass production of steel. Before the development of an open-mouth furnace, the process used a molten pig iron to melt iron. The real difference with this process was that air was forced through the molten iron to remove impurities.
