Q: Write a multi-choice question for the following article: Article: Mass transportation revised the social and economic fabric of the American city in three fundamental ways.It catalyzed physical expansion, it sorted out people and land uses, and it accelerated the inherent instability of urban life.By opening vast areas of unoccupied land for residential expansion, the omnibuses, horse railways, commuter trains, and electric trolleys pulled settled regions outward two to four times more distant form city centers than they were in the premodern era.In 1850, for example, the borders of Boston lay scarcely two miles from the old business district; by the turn of the century the radius extended ten miles.Now those who could afford it could live far removed from the old city center and still commute there for work, shopping, and entertainment.The new accessibility of land around the periphery of almost every major city sparked an explosion of real estate development and fueled what we now know as urban sprawl.Between 1890 and 1920, for example, some 250,000 new residential lots were recorded within the borders of Chicago, most of them located in outlying areas.Over the same period, another 550,000 were plotted outside the city limits but within the metropolitan area.Anxious to take advantage of the possibilities of commuting, real estate developers added 800,000 potential building sites to the Chicago region in just thirty years - lots that could have housed five to six million people. Of course, many were never occupied; there was always a huge surplus of subdivided, but vacant, land around Chicago and other cities.These excesses underscore a feature of residential expansion related to the growth of mass transportation: urban sprawl was essentially unplanned.It was carried out by thousands of small investors who paid little heed to coordinated land use or to future land users.Those who purchased and prepared land for residential purposes, particularly land near or outside city borders where transit lines and middle-class inhabitants were anticipated, did so to create demand...

Q: Write a multi-choice question for the following article: Article: If you and your friends wish to share a secret, you can write it in code, and no one else will be able to read it. Codes are one way of writing in secret. Ciphers are another. In a code each word is written as a secret code word or a code number. In a cipher each letter is changed. Codes and ciphers have played an important role in the history of the world. Julius Caesar, the Roman ruler who defeated almost all the countries in Europe about 2,000 years ago, used a cipher when he sent secret messages to his troops. During the American Revolution, George Washington's spies used a kind of code to send his information about the enemy before his military action. In World War II, the Americans"broke"or figured out Japan's most important navy codes and got enough information to destroy a powerful Japanese fleet. Storekeepers use codes to mark their goods. The codes show how much is paid for the goods or when they are added to the stock. Businessmen use codes to hide plans from their business enemies. Sometimes personal letters or diaries are written in code. Many people enjoy figuring out codes and ciphers simply as a hobby. In the 16th century, codes and ciphers were very popular among scientists. They wrote messages to each other in code so that no one else would learn their secrets. Geronimo Gardano, an Italian astrologer , mathematician, and doctor, invented the trellis cipher. He took two sheets of paper and cut exactly the same holes in each one. Then he sent one sheet, which he called a trellis, to a friend and kept the other for himself. Whenever he wanted to write a message, he put his trellis over a clean sheet of paper and wrote the secret message through the holes. There he removed the trellis and filled the rest of the paper with words that would make sense. When his friend received it, he put his trellis over the writing and read the secret message.
