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.Alzheimer's disease impairs a person's ability to recall memories, both distant and as recent as a few hours before. Although there is not yet a cure for the illness, there may be hope for a cure with a protein called nerve growth factor. The protein is produced by  nerve cells in the same region of the brain where Alzheimer's occurs.Based on this relationship, scientists from the University of Lund in Sweden and the University of California at San Diego designed an experiment to test whether doses of nerve growth factor could reverse the effects of memory loss caused by Alzheimer's. Using a  group of rats with impaired memory, the scientists gave half of the rats doses of nerve growth factor while giving the other half a blood protein as a placebo, thus creating a control group. At the end of the four-week test, the rats given the nerve growth factor performed equally to rats with normal memory abilities. While the experiments  do not show that nerve growth factor can stop the general process of deterioration caused by Alzheimer's, they do show potential as a means to slowing the process significantly.

Read the passage carefully, then choose the best answer for each question.THE DISEASE DETECTIVESix 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 CauseFirst, 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 ClosedBesser 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.
