+ u4 Z# {7 }3 f" U: y" Y  Directions: The questions in this section are based on the reasoning contained in brief statements or passages. For some questions, more than one of the choices could conceivably answer the question. However, you are to choose the best answer: that is the response that most accurately and completely answers the question.

7 t* O* Y* H/ C2 ]2 F5 O  1.Biotechnology companies say that voluntary guideline for their industry are sufficient to ensure that no harm will result when a genetically altered organism is released into the environment. It is foolish, however, to rely on assurances from producers of genetically altered organisms that their products will not be harmful. Therefore, a biotechnology company should be required to apply to an independent regulatory board composed of scientists outside the biotechnology industry for the right to sell newly created organisms.4 E2 }2 z* {- q( p

  2. Zoo director: The city is in a financial crisis and must reduce its spending. Nevertheless, at least one reduction measure in next years budget, cutting City Zoos funding in half, is false economy. The zoo's current budget equals less than 1 percent of the city's deficit, so withdrawing support from the zoo does little to help the city's financial situation. Furthermore, the zoo, which must close if its budget is cut, attracts tourists arid tax dollars to the city. Finally, the zoo adds immeasurably to the city's cultural climate and thus makes the city an attractive place for business to locate.6 y7 a% N. R, l8 ^, y* ~
  Which one of the following is the main conclusion of the zoo director's argument?
3 T# e7 ^* s; N9 z/ C  (A) Reducing spending is the only means the city has of responding to the current financial crisis.1 R7 a( @* i  X" k! b* i

  The flawed reasoning in the argument above most closely parallels that in which one of the following?1 t" o4 Q' O) u6 S+ o% l8 [6 Z
  (A) Tulip bulbs will not produce flowers unless they are chilled for two months. Since the tulip bulbs in the clay pot were not chilled for two months, these bulbs will not produce flowers.0 ^0 ~: ]5 x2 o! o8 U1 `
  (B) Beets do not grow well unless the soil in which they are grown contains trace amounts of boron. Since the beets in this plot are growing well, the soil in the plot must contain trace amounts of boron.

: |& w2 S$ D2 s$ g0 X  5. The ends of modern centuries have been greeted with both apocalyptic anxieties and utopian fantasies. It is not surprising that both reactions have consistently proven to be misplaced.
