31. What is the main reason for dropping out？

One of the industrial giants who changed American society was Henry Ford. Born on a farm in Michigan in 1863, he grew up to bring forth some of the most revolutionary improvements in automotive technology in the early 20th century. His outstanding mechanical ability led him to become interested in the new automobiles in the early 1900s. Though he did not invent the automobile, he improved upon everyone else's designs. Ford's personality was not all thrift, efficiency, and ingenuity, however. He was a man who was cold and who could not keep pace with the competition due to his own rigidity. His company suffered because of his desire to maintain the status quo instead of meeting and beating the competition by changing his product. Finally, he saw that he must change or lose out; therefore, he introduced the eight-cylinder engine and once again took over the automobile market. Ford left a legacy of millions of dollars, millions of jobs for American workers, and millions of satisfied customers.
