127. Anthropologists assert that cultures advance only when independence replaces dependence---that is, only when imposition by outsiders is replaced by initiative from within. In other words, the natives of a culture are the only ones who can move that culture foward. Non-natives may provide valuable advice, but any imposition of their views threatens independence and thus progress. If one looks at individual schools as separate cultures, therefore, the key to educational progress is obvious:
which one of the following best completes the passage?
(A) individual schools must be independent of outside imposition
(B) some schools require more independence than others, depending on the initiative of their staffs and students
(C) school systems officials must tailor their initiatives for change to each individual school in the system
(D) outsiders must be prevented from participation in schools’ efforts to advance
(E) the more independent a school is, the more educational progress it will make
key: A
128. The public in the United States has in the past been conditioned to support a substantial defense budget by the threat of confrontation with the Eastern bloc. Now that that threat is dissolving, along with the Eastern bloc itself, it is doubtful whether the public can be persuaded to support an adequate defense budget.
Which one of the following indicates a weakness in the position expressed above?
(A) It presupposes that public opinion can be manipulated indefinitely, without the public’s becoming aware of that manipulation.
(B) It refers to past and present events that do not have a causal connection with public support of the budget.
(C) It assumes as fact what it seeks to establish by
(D) It fails to give any reason for the judgement it reaches.
(E) It hinges on the term “adequate”, the precise meaning of which requires reevaluation in the new context.
KEY:E
Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmosphere carbon causes decreased evaporation from the oceans, which cause less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax---nature will continually adjust the carbon level.
133. Which one of the following, if true, would most weaken the argument in the passage?
(A) Plant life cannot survive without atmospheric carbon.
(B) It is not clear that breathing excess carbon in the atmosphere will have a negative effect on human life.
(C) Carbon is part of the chemical “blanket” that keeps the Earth warm enough to sustain human life.
(D) Breathing by animals releases almost 30 times as much carbon as does the burning of fossil fuels.
(E) The natural adjustment process, which occurs over millions of years, allow wide fluctuations in the carbon level in the short term. |
