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 questions.

For a time, the Hubble telescope was the brunt of jokes and subject to the wrath of those who believed the U.S. government had spent too much money on space projects that served no valid purpose. The Hubble was sent into orbit with a satellite by the Space Shuttle Discovery in 1990 amid huge hype and expectation. Yet after it was in position, it simply did not work, because the primary mirror was misshapen. It was not until 1993 that the crew of the Shuttle Endeavor arrived like roadside mechanics, opened the hatch that was installed for the purpose, and replaced the defective mirror with a good one.

Suddenly, all that had originally been expected came true. The Hubble telescope was indeed the “window on the universe,” as it had originally been dubbed. When you look deep into space, you are actually looking back through time, because even though light travels at 186,000 miles a second, it requires time to get from one place to another. In fact, it is said that in some cases, the Hubble telescope is looking back eleven billion years to see galaxies already forming. The distant galaxies are speeding away from Earth, some traveling at the speed of light.

Hubble has viewed exploding stars such as the Eta Carinae, which clearly displayed clouds of gas and dust billowing outward from its poles at 1.5 million miles an hour. Prior to Hubble, it was visible from traditional telescopes on earth, but its details were not ascertainable. But now, the evidence of the explosion is obvious. The star still burns five million times brighter than the sun and illuminates clouds from the inside.

Hubble has also provided a close look at black holes, which are described as cosmic drains. Gas and dust swirl around the drain and are slowly sucked in by the incredible gravity. It has also looked into an area that looked empty to the naked eye and, within a region the size of a grain of sand, located layer upon layer of galaxies, with each galaxy consisting of billions of stars.

          The Hubble telescope was named after Edwin Hubble, a 1920s astronomer who developed a formula that expresses the proportional relationship of distances between clusters of galaxies and the speeds at which they travel. Astronomers use stars known as Cepheid variables to measure distances in space. These stars dim and brighten from time to time, and they are photographed over time and charted. All the discoveries made by Hubble have allowed astronomers to learn more about the formation of early galaxies.

The author states that the Hubble was not always popular because__________ .

A. it was more expensive than most space shuttles.

B. many people believed space exploration was a waste of time.

C. people were afraid of what might be found.

D. it was defective for its first three years in space.

In fact, it is said that in some cases, the Hubble telescope is looking back eleven billion years to see galaxies already forming. The distant galaxies are speeding away from Earth, some traveling at the speed of light.

Hubble has viewed exploding stars such as the Eta Carinae, which clearly displayed clouds of gas and dust billowing outward from its poles at 1.5 million miles an hour. Prior to Hubble, it was visible from traditional telescopes on earth, but its details were not ascertainable. But now, the evidence of the explosion is obvious. The star still burns five million times brighter than the sun and illuminates clouds from the inside.

Hubble has also provided a close look at black holes, which are described as cosmic drains. Gas and dust swirl around the drain and are slowly sucked in by the incredible gravity. It has also looked into an area that looked empty to the naked eye and, within a region the size of a grain of sand, located layer upon layer of galaxies, with each galaxy consisting of billions of stars.

          The Hubble telescope was named after Edwin Hubble, a 1920s astronomer who developed a formula that expresses the proportional relationship of distances between clusters of galaxies and the speeds at which they travel. Astronomers use stars known as Cepheid variables to measure distances in space. These stars dim and brighten from time to time, and they are photographed over time and charted. All the discoveries made by Hubble have allowed astronomers to learn more about the formation of early galaxies.

The word billowing in the third paragraph is closest in meaning to __________ .

A. sitting

B. exploding

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

        These days it is easy for most of us to get a hold of the latest books or magazines. We can go to bookstores, order them through the Internet, or borrow them from the local libraries. Now imagine having to walk miles and miles through a hot sandy desert just to borrow a book. This is the reality for people living in the villages of the Carissa region of Kenya in East Africa.

        In 1996, librarian Wycliffe Oluoch used to spend each day waiting for people to come to borrow some of the 24,000 books in his library in Carissa. The library had no shortage of books, but people weren’t coming to read them. It was too much effort to walk through the desert just to borrow books. Oluoch racked his brain for ways to entice people into the library. After a lot of thought, he hit upon a great idea. If people wouldn’t come to the library, then he would have to take the library to them. Oluoch strapped boxes of books onto the backs of camels, and created the Mobile Camel Library.

        Starting with three camels in 1996, but more recently expanding the service to six camels, the Mobile Camel Library serves over one million people. Twice a month, the camel library can be seen carrying books all around the Carissa region. These hard-working animals need little water and can carry up to 500 pounds of books across the sands. A librarian, a library assistant, a herdsman, and a lookout all travel with the camels. The lookout helps protect the books from thieves.

        The children of Carissa love the camel library and appreciate Oluoch’s effort. Eleven-year-old Mohamud Mohamed reads his library books carefully and always returns them on time. He knows the Carissa library punishes people for losing books, just like any other library. However, the punishment is very stiff compared to that of other libraries. If a village loses a book, the camel library stops visiting.
