32. GWD30-Q32:

A major chemical spill occurred five years ago at Baker’s Beach, the world’s sole nesting ground for Merrick sea turtles, and prevented nearly all the eggs laid that year from hatching.  Yet the number of adult female Merricks returning to lay their eggs at Baker’s Beach has actually increased somewhat since five years ago.  Clearly, environmentalists’ prediction that the world’s Merrick population would decline as a result of the spill has proven unfounded.

Which of the following, if true, most seriously undermines the argument offered in refutation of the environmentalists’ prediction?

1. The chemical spill five years ago occurred at a time when there were neither Merrick sea turtles nor Merrick sea turtle eggs on Baker’s Beach.
2. Female Merrick sea turtles begin returning to Baker’s Beach to lay their eggs when they are ten years old.
3. Under normal conditions, only a small proportion of hatchling female Merrick sea turtles survive in the ocean until adulthood and return to lay their eggs at Baker’s Beach.
4. Environmental pressures unrelated to the chemical spill have caused a significant decline in the population of one of the several species of sea birds that prey on Merrick sea turtle eggs.
                            
5. After the chemical spill, an environmental group rejected a proposal to increase the Merrick sea turtle population by transferring eggs from Baker’s Beach to nearby beaches that had not been affected by the spill.

答案B   我选D

Which of the following is an assumption on which the argument relies?

1. The tetracycline deposits did not form after the bodies were buried.
2. The diseases other than typhus to which the ancient Nubians were exposed would not be affected by tetracycline.
3. Typhus is generally fatal.
4. Nubian grain became contaminated with tetracycline-producing bacteria prior to being harvested.
5. Bread and beer were the only foods eaten by the ancient Nubians which could have contained tetracycline.

   Answer: A

Q30:

The ancient Nubians inhabited an area in which typhus occurs, yet surprisingly few of their skeletons show the usual evidence of this disease.  The skeletons do show deposits of tetracycline, an antibiotic produced by a bacterium common in Nubian soil.  This bacterium can flourish on the dried grain used for making two staples of the Nubian diet, beer and bread.  Thus, tetracycline in their food probably explains the low incidence of typhus among ancient Nubians.

Which of the following is an assumption on which the argument relies?

1. Infectious diseases other than typhus to which the ancient Nubians were exposed are unaffected by tetracycline.

2. Tetracycline is not rendered ineffective as an antibiotic by exposure to the processes involved in making bread and beer.

3. Typhus cannot be transmitted by ingesting bread or beer contaminated with the infectious agents of this disease.

4. Bread and beer were the only items in the diet of the ancient Nubians which could have contained tetracycline.

5. Typhus is generally fatal.

答案B

If the statements above are true, which of the following practices, if adopted by an investment bank, would hinder its long-term success?

1. Evaluating and rewarding the bank’s analysts on the basis of recommendations made by managers who are solely engaged in raising capital for clients

3. Sharing the task of raising capital for a client with other investment banks
4. Ensuring that conflicts between analysts and those who raise capital for clients are carefully mediated and resolved by impartial arbitrators
5. Monitoring the success or failure of analysts’ current predictions about how companies will perform financially, in order to determine the value of future predictions
