Câu hỏi: Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer for each of the questions from 30 to 34.
Escalators are very commonly used today in shopping malls, government buildings, amusement parks, and at many other locations. They are staircases which move via a conveyor belt, with tracks which maintain each step in a horizontal position. However, the escalator began as an amusement and not as a practical method of transport. In 1892, Jesse Reno patented his moving stairs, or "inclined elevator". Three years later, he created a novelty ride at Coney Island from his patented design: a moving stairway that elevated passengers on a conveyor belt at a 25 degree angle.
Charles Seeberger, together with the Otis Elevator Company, produced the first commercial escalator in 1899 at the Otis factory in Yonkers, N. Y. The Seeberger - Otis wooden escalator won first prize at the Paris 1900 Exposition Universelle in France. In 1910Charles Seeberger sold his patent rights for the escalator to the Otis Escalator Company, which also bought Jesse Reno's escalator patent in 1911. Otis has dominated escalator production since that time, by combining and enhancing various designs including the cleated, level steps still in use today. The word "escalator", which was at first a trademarked name, has become a common descriptive term.
How long have elevators been produced as a mode of transport?
A. More than 50 years
B. More than 70 years
C. More than 100 years
D. More than 125 years
