Read the passage carefully, then choose the best answer for each question.
THE DISEASE DETECTIVE
Six children were in the hospital. They were very sick, but the doctors didn't know what to do. They called Dr. Richard Besser, an expert on strange illnesses.  Dr. Besser knew just what to do.
Finding a Cause
First, Dr. Besser needed to find the cause of the illness. He used a microscope to look for germs like bacteria in the children's bodies. Dr. Besser found that all the children had a strain of the bacteria E. coli. Then he looked at the bacteria's DNA. The DNA showed him that this strain of E. coli was dangerous to humans.
Where Did It Come From?
Dr. Besser knew E. coli could move from animals to humans. Perhaps the children had touched animals that carried the bacteria? Besser found other E. coli cases in the area where the children lived. But it wasn't enough.
Besser then made a list of what the sick children had eaten. They had all eaten cheese, apple juice, and fish. He then made a list of what healthy children in the area had eaten, and compared his lists. They had eaten the cheese and fish, but not the apple juice.
Case Closed
Besser went to where the apple juice was made. He saw that there were animals around the apple trees, and he saw the workers using dirty apples that had fallen on the ground. More importantly, he saw that the apples were not washed before the juice was made, and that the juice was not heated. Doing these things would kill the bacteria. Besser then knew it was the apple juice that made the children sick.
Besser's E. coli case has a happy ending. The children got better. And what Besser learned that day now helps keep others safe.
Who does “they” refer to?
A.the sick children
B.the healthy children
C.both the sick and the healthy children
D.neither the sick nor the healthy children

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. 
People used to know more or less how their children would live. Now things are changing so quickly that they don’t even know what their own lives will be like in a few years’ time. What follows is not science fiction. It is how experts see the future.
            You are daydreaming behind the steering wheel; is it too dangerous? No! That’s no problem because you have it on automatic pilot, and with its hi-tech computers and cameras, your car “know” how to get you home safe and sound.
            What is for lunch? In the old days you used to stop off to buy a hamburger or a pizza. Now you use your diagnostic machine to find out which foods your body needs. If your body needs more vegetables and less fat, your food-preparation machine makes you a salad.
            After lunch, you go down the hall to your home office. Here you have everything you need to do your work. Thanks to your information screen and your latest generation computer, you needn’t go to the office any more. The information screen shows an urgent message from a co-worker in Brazil. You can instantly send back a reply to him and go on to deal with other matters.

A.People will go to work as they do today.
B.Hi-tech equipment will be out of the question.
C.It will be dangerous to drive cars because they are too fast.

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. 
Herman Melville, an American author best known today for his novel Moby Dick, was actually more popular during his lifetime for some of his other works. He traveled extensively and used the knowledge gained during his travels as the basis for his early novels. In 1837, at the age of eighteen, Melville signed as a cabin boy on a merchant ship that was to sail from his Massachusetts home to Liverpool, England. His experiences on this trip served as a basis for the novel Redburn (1849). In 1841 Melville set out on a whaling ship headed for the South Seas. After jumping ship in Tahiti, he wandered around the islands of Tahiti and Moorea. This South Sea island sojourn was a backdrop to the novel Omoo (1847). After three years away from home, Melville joined up with a U.S. naval frigate that was returning to the eastern United States around Cape Horn. The novel White-Jacket (1850) describes this lengthy voyage as a navy seaman. With the publication of these early adventure novels, Melville developed a strong and loyal following among readers eager for his tales of exotic places and situations. However, in 1851, with the publication of Moby Dick, Melville's popularity started to diminish. Moby Dick, on one level the saga of the hunt for the great white whale, was also a heavily symbolic allegory of the heroic struggle of man against the universe. The public was not ready for Melville's literary metamorphosis from romantic adventure to philosophical symbolism. It is ironic that the novel that served to diminish Melville's popularity during his lifetime is the one for which he is best known today.

According to the passage, Moby Dick is__________.
A.A. symbolic of humanity fighting the universe       
B.B. a single-faceted work
C.C. a short story about a whale                                 
D.D. a 47 adventure
