Mars is the fourth planet from the Sun and is commonly referred to as the Red Planet. The rocks, soil and sky have a red or pink hue. The distinct red color was observed by stargazers throughout history. It was given its name by the Romans in honor of their god of war. Other civilizations have had similar names. The ancient Egyptians named the planet Her Descher meaning the red one.

Before space exploration, Mars was considered the best candidate for harboring extraterrestrial life. Astronomers thought they saw straight lines crisscrossing its surface. This led to the popular belief that irrigation canals on the planet had been constructed by intelligent beings. In 1938, when Orson Welles broadcasted a radio drama based on the science fiction classic War of the Worlds by H.G. Wells, enough people believed in the tale of invading Martians to cause a near panic.

Another reason for scientists to expect life on Mars had to do with the apparent seasonal color changes on the planet's surface. This phenomenon led to speculation that conditions might support a bloom of Martian vegetation during the warmer months and cause plant life to become dormant during colder periods.

By the mid-nineteenth century, the term icebox had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward- looking city dealers in fresh meat, fresh fish, and butter.

By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward- looking city dealers in fresh meat, fresh fish, and butter. After the Civil War(1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the

icebox, a precursor of the modern refrigerator, had been invented. Making an efficient ice box was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.

But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, forwhich the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

1. The phrase "forward-looking" in line 3 is closest in meaning to .

A. progressive B. popular C. thrifty D. well-established

2.The author mentions fish in line 5 because .

A. many fish dealers also sold ice

B. fish was shipped in refrigerated freight cars

C. fish dealers were among the early commercial users of ice

D. fish was not part of the ordinary person's diet before the invention of the icebox

3. The word "it" in line 5 refers to .

A. fresh meat

B. the Civil War

C. ice

D. a refrigerator

4. The word "rudimentary" in line 10 is closest in meaning to .

A. growing B. undeveloped C. necessary D. uninteresting

5. The author describes Thomas Moore as having been "on the right track" to indicate that

A. the road to the market passed close to Moore's farm

B. Moore was an honest merchant

C. Moore was a prosperous farmer

D. Moore's design was fairly successful

6. According to the passage, Moore's icebox allowed him to .

A. charge more for his butter B. travel to market at night

C. manufacture butter more quickly D. produce ice all year round

7. According to the information in the second paragraph, an ideal icebox would ...................... .

A. completely prevent ice from melting B. stop air from circulating
