Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

(1) After the Anasazi abandoned southwestern Colorado in the late 1200s or early 1300s, history’s pages are blank. The Anasazi were masons and apartment builders who occupied the deserts, river valleys, and mesas of this region for over a thousand years, building structures that have weathered the test of time.

(2) The first Europeans to visit southwestern Colorado were the ever-restless, ambitious Spanish, who sought gold, pelts, and slaves. In 1765, under orders from the Spanish governor in Santa Fe, Juan Maria Antonio Rivera led a prospecting and trading party into the region. Near the Dolores River in southwestern Colorado, he found some insignificant silver-bearing rocks, and it is thought that it was he who named the mountains nearby the Sierra de la Plata or the Silver Mountains. Rivera found little of commercial value that would interest his superiors in Santa Fe, but he did open up a route that would soon lead to the establishment of the Old Spanish Trail. This expedition and others to follow left names on the land which are only reminders we have today that the Spanish once explored this region.

(3) In 1776, one of the men who had accompanied Rivera, Andre Muniz, acted as a guide for another expedition. That party entered southwestern Colorado in search of a route west to California, traveling near today’s towns of Durango and Dolores. Along the way, they camped at the base of a large green mesa which today carries the name Mesa Verde. They were the first Europeans to record the discovery of an Anasazi archeological site in southwestern Colorado.

(4) By the early 1800s, American mountain men and trappers were exploring the area in their quest for beaver pelts. Men like Peg-leg Smith were outfitted with supplies in the crossroads trapping town of Taos, New Mexico. These adventurous American trappers were a tough bunch. They, possibly more than any other newcomers, penetrated deeply into the mountain fastness of southwestern Colorado, bringing back valuable information about the area and discovering new routes through the mountains. One of the trappers, William Becknell, the father of the Santa Fe Trail, camped in the area of Mesa Verde, where he found pottery shards, stone houses, and other Anasazi remains.

Which of the following is most likely true about William Becknell?

A. He collected Anasazi pottery.

B. He was well-educated about the Anasazi culture. 

C. He built the Santa Fe Trail.

D. He was wealthy from selling beaver pelts.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions.

One of the highest honors for formalists, writers, and musical composers is the Pulitzer Prize. First awarded in 1927, the Pulitzer Prize has been won by Ernest Hemingway, Harper Lee, John F. Kennedy, and Rodgers and Hammerstein, among others. As with many famous awards, this prize was named after its founder, Joseph Pulitzer.

Joseph Pulitzer’s story, like that of many immigrants to the United States, is one of hardship, hard work and triumph. Born in Hungary, Joseph Pulitzer moved to United States in 1864. He wanted to be a reporter, but he started his American life by fighting in the American Civil War. After the war, Pulitzer worked for the German - language newspaper, the Westliche Post. His skills as a reporter were wonderful, and he soon became a partial owner of the paper.

In 1978, Pulitzer was able to start a newspaper of his own. Right from the first edition, the newspaper took a controversial approach to new. Pulitzer wanted to appeal to the average reader, so he produced exciting stories of scandal and intrigue. Such an approach is commonplace today, but in Pulitzer’s time it was new and different. The approach led to the discovery of many instances of corruption by influential people. Pulitzer ‘paper became very famous and is still produced today.

The success of Joseph Pulitzer’s newspaper made him a very wealthy man, so he wanted to give something back to his profession. Throughout his later years, he worked to establish university programs for the teaching of journalism, and he funded numerous scholarships to assist journalism students. Finally, he wanted to leave a legacy that would encourage writers to remember the importance of quality. On his death, he gave two million dollars to Columbia University so they could award prizes to great writers.

The Pulitzer Prize recipients are a very select group. For most, winning a Pulitzer Prize is the highlight of their career. If an author, journalist, or composer you know has won a Pulitzer Prize, you can be sure they are at the top of their profession.

According to the reading passage, why did Joseph Pulitzer invent the Pulitzer Prize?

A. to encourage people to remember his name and success

B. encourage writers to remember the importance of quality

C. to encourage journalism students to achieve their goals

D. to encourage work of the Pulitzer winners
