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 century before the Erie Canal was built, there was much discussion among the general population of the Northeast as to the need for connecting the waterways of the Great Lakes with the Atlantic Ocean. A project of such monumental proportions was not going to be undertaken and completed without a supreme amount of effort.
The man who was instrumental in accomplishing the feat that was the Erie Canal was Dewitt Clinton. As early as 1812, he was in the nation's capital petitioning the federal government for financial assistance on the project, emphasizing what a boon to the economy of the country the canal would be; his efforts with the federal government, however, were not successful.
In 1816, Clinton asked the New York State Legislature for the funding for the canal, and this time he did succeed. A canal commission was instituted, and Clinton himself was made head of it. One year later, Clinton was elected governor of the state, and soon after, construction of the canal was started.
The canal took eight years to complete, and Clinton was on the first barge to travel the length of the canal, the Seneca Chief, which departed from Buffalo on October 26, 1825, and arrived in New York City on November 4. Because of the success of the Erie Canal, numerous other canals were built in other parts of the country.
The pronoun “it” in the 3rd paragraph refers to which of the following?
A.The canal       
B.The New York State Legislation
C.The state governor   
D.The commission

Unlike these fish, which are actually extinct, the coelacanth is a type of fish that was believed to be extinct. However, an unexpected twentieth- century rediscovery of living coelacanths has brought about a reassessment of the status of the prehistoric sea creature that was believed to have long since disappeared from the Earth.
From fossil remains of the coelacanth, paleontologists have determined that the coelacanth was in existence around 350 million years ago, during the Paleozoic Era, more than 100 million years before the first dinosaurs arrived on the Earth. The most recent fossilized coelacanths date from around 70 million years ago, near the end of the age of dinosaurs. Because no fossilized remnants of coelacanth was believed to have died out around the same time as the dinosaurs.
The prehistoric coelacanth studied by paleontologists had distinctive characteristics that differentiated it from other fish. It was named for its hollow spine and was known to have been a powerful carnivore because of its many sharp teeth and a special joint in the skull that allowed the ferocious teeth to move in coordination with the lower jaw. It also had a pair of fins with unusual bony and muscular development that allowed the coelacanth to dart around the ocean floor. These fins also enable the coelacanth to search out prey trying to hide on the ocean bottom.
In 1938, a living specimen of the coelacanth was discovered in the catch of a fishing boat off the coast of South Africa, and since then numerous other examples of the coelacanth have been found in the waters of the Indian Ocean. This modern version of the coelacanth is not exactly the same as its prehistoric cousin. Today's coelacanth is larger than its prehistoric relative, measuring up to six feet in length and weighing up to 150 pounds. However, the modern version of the coelacanth still possesses the characteristic hollow spine and distinctive fins with their unusual bony and muscular structure.
What is stated in the passage about the prehistoric coelacanth?
A.It had few teeth.
B.It was a rather feeble fish.
C.It lived on plants. 
D.It moved its teeth in an unusual way.

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 from 28 to 34.
Therapeutic cloning
Korea’s recent unveiling of the world’s first cloned dog was welcomed by King Chow, assistant professor of biotechnology at the Hong Kong University of Science and Technology, but he also warned that we need to be on guard against possible reproductive cloning. Professor Chow went on to explain that, “The development of the technology is a good thing in itself but how we monitor it and who we allow to use it will be of great importance”.
Professor Chow is one of many academics who feel that a clear line must be drawn between reproductive cloning and therapeutic cloning. Therapeutic cloning involves the use of embryonic stem cells to develop human cells or organs that can be used to cure diseases such as Parkinson’s and diabetes. People in wheelchairs may be able to walk again thanks to this technology as scientists believe that they can clone new cells to repair back and neck injuries.
Reproductive cloning
Reproductive cloning involves implanting a cloned embryo into a uterus in the hope of producing a healthy foetus. A company called Clonaid claims to have successfully cloned thirteen human babies. They say that all of the babies are healthy and are in various location including Hong Kong, UK, Spain and Brazil. Clonaid states that they are using human cloning to assist infertile couples, homosexual couples and families who have lost a beloved relative.
The same technology can be used for animal cloning. If endangered species such as the giant panda and Sumatran tiger could be cloned, they could be saved from extinction. Livestock such as cows could also be cloned to allow farmers to reproduce cattle that produce the best meat and most milk. This could greatly help developing countries where cows produce significantly less meat and milk.
According to the passage, which of the following is NOT true?
A.Cloning technology can help cure back and neck injuries.
B.The first dog to be cloned was in Korea.
C.Many countries can use cloning technology to produce more meat and milk.
D.Diabetes can’t be cured by using cloning technology.
