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 implies that at the time the Hubble was initially deployed from the Earth _______ .

A. there was little attention paid to it.

B. it was already known that the mirror was defective.

C. there was considerable excitement about potential uses.

D. all attention was focused on the space shuttle, not the Hubble.

 Skydivers Promote Tourism Industry in Egypt 

In an effort to boost Egypt's flagging tourism industry, skydivers recently took part in a high-flying competition over Egypt's Great Pyramids.

Participants say the event was aimed at attracting more visitors to the country, as Egypt has suffered a $1.3 billion drop in tourism revenue over the past few months.

More than 200 skydivers from 17 countries took part in the recent three-day competition, with participants jumping from helicopters more than 1,100 meters high, and aiming for specific targets on land.

The event, organizers say, sends a message to the world.

"Egypt is strong and it will never be affected by all the chaos going on,” said General Soliman El-Hadary of the Egyptian Union for Air Sports. “We want to emphasize to the world that our country is safe and tourists are welcome."

Tourism is one of the most important sectors of Egypt's economy.

Skydivers thúc đẩy ngành du lịch ở Ai Cập
Trong một nỗ lực để thúc đẩy ngành công nghiệp du lịch suy giảm của Ai Cập, Skydivers gần đây đã tham gia một cuộc thi bay cao hơn Kim tự tháp của Ai Cập.
Những người tham gia nói rằng sự kiện này là nhằm thu hút du khách nhiều hơn cho đất nước, như Ai Cập đã bị giảm $ 1.3 tỷ doanh thu du lịch trong vài tháng qua.
Hơn 200 Skydivers từ 17 quốc gia đã tham gia cuộc thi ba ngày gần đây, với sự tham gia nhảy từ máy bay trực thăng cao hơn 1.100 mét, và hướng tới mục tiêu cụ thể về đất đai.
Các sự kiện, tổ chức cho rằng, sẽ gửi một thông điệp tới thế giới.
"Ai Cập là mạnh mẽ và nó sẽ không bao giờ bị ảnh hưởng bởi tất cả sự hỗn loạn đang diễn ra," Tướng Suleiman El-Hadary của Liên minh Ai Cập cho Air Sports cho biết. "Chúng tôi muốn nhấn mạnh với thế giới rằng đất nước của chúng tôi là an toàn và du khách được chào đón. "
Du lịch là một trong những lĩnh vực quan trọng nhất của nền kinh tế Ai Cập.
