Four legal approaches may be followed in attempting to channel technological development in socially useful direction: specific directives, market incentive modifications, criminal prohibitions, and changes in decision-making structures. Specific directives involve the government s identifying one or more factors controlling research, development, or implementation of a given technology. Directives affecting such factors may vary from administrative regulation of private activity to government ownership of a technological operation. Market incentive modifications are deliberate alterations of the market within which private decisions regarding the development and implementation of technology are made. Such modifications may consist of imposing taxes to cover the costs to society of a given technology, granting subsidies to pay for social benefits of a technology, creating the right to sue to prevent certain technological development, or easing procedural rules to enable the recovery of damages to compensate for harm caused by destructive technological activity. Criminal prohibitions may modify technological activity in areas impinging on fundamental social values, or they may modify human behavior likely to result from technological applications for example, the deactivation of automotive pollution control devices in order to improve vehicle performance. Alteration of decision-making structures includes all possible modifications in the authority, constitution, or responsibility of private and public entities deciding questions of technological development and implementation. Such alterations include the addition of public-interest members to corporate boards, the imposition by statute of duties on governmental decision-makers, and the extension of warranties in response to consumer action.
Effective use of these methods to control technology depends on whether or not the goal of regulation is the optimal allocation of resources. When the object is optimal resource allocation, that combination of legal methods should be used that most nearly yields the allocation that would exist if there were no external costs resulting from allocating resources through market activity. There are external costs when the price set by buyers and sellers of goods fails to include some costs, to anyone, that result from the production and use of the goods. Such costs are internalized when buyers pay them.
Air pollution from motor vehicles imposes external costs on all those exposed to it, in the form of soiling, materials damage, and disease: these externalities result from failure to place a price on air, thus making it a free good, common to all. Such externalities lead to nonoptimal resource allocation, because the private net product and the social net product of market activity are not often identical. If all externalities were internalized, transactions would occur until bargaining could no longer improve the situation, thus giving an optimal allocation of resources at a given time.
17. The passage is primarily concerned with describing
objectives and legal method for directing technological development
technical approaches to the problem of controlling market activity
economic procedures for facilitating transactions between buyers and sellers
reasons for slowing the technological development in light of environmentalist objections
technological innovations making it possible to achieve optimum allocation of resources
18. The author cites air pollution from motor vehicles in lines 54-56 in order to
revise cost estimates calculated by including the costs of resources
evaluate legal methods used to prevent technological developments
give examples of costs not included in buyer-seller bargains
refute hypotheses not made on the basis of monetary exchange values
commend technological research undertaken for the common welfare
19. According to the passage, transactions between private buyers and sellers have effects on society that generally
are harmful when all factors are considered
give rise to ever-increasing resource costs
reflect an optimal allocation of natural resources
encompass more than the effects on the buyers and sellers alone
are guided by legal controls on the development of technology
20. It can be inferred from the passage that the author does NOT favor which of the following?
Protecting the environment for future use
Changing the balance of power between opposing interests in business
Intervening in the activity of the free market
Making prices reflect costs to everyone in society
Causing technological development to cease
21. A gasoline-conservation tax on the purchase of large automobiles, with the proceeds of the tax rebated to purchasers of small automobiles, is an example of
a specific directive
a market incentive modification
an optimal resource allocation
an alteration of a decision-making structure
an external cost
22. If there were no external costs, as they are described in the passage, which of the following would be true?
All technology-control methods would be effective.
Some resource allocations would be illegal.
Prices would include all costs to members of society.
Some decision-making structures would be altered.
The availability of common goods would increase.
23. The author assumes that, in determining what would be an optimal allocation of resources, it would be possible to
assign monetary value to all damage resulting from the use of technology
combine legal methods to yield the theoretical optimum
convince buyers to bear the burden of damage from technological developments
predict the costs of new technological developments
derive an equation making costs depend on prices
24. On the basis of the passage, it can be inferred that the author would agree with which of the following statements concerning technological development?
The government should own technological operations.
The effect of technological development cannot be controlled.
Some technological developments are beneficial.
The current state of technological development results in a good allocation of resources.
Applications of technological developments are criminally destructive.
The whole biosphere, like the individual organisms that live inside it, exists in a chemically dynamic state . In this homeostatic system, a great number of organic compounds are synthesized, transformed, and decomposed continuously; together, these processes constitute the major parts of the carbon cycle. For the smooth operation of this cycle, degradation is just as important as synthesis: the green plants produce great quantities of polymers, such as cellulose, and innumerable other compounds like alkaloids, terpenes, and flavonoids, that green plants cannot use as sources of energy during respiration. The release of the carbon in these compounds for recycling depends almost entirely on the action of both aerobic and anaerobic bacteria and certain types of fungi. Some bacteria and fungi possess the unique and extremely important biochemical asset of being able to catalyze the oxidation of numerous inert products, thereby initiating reaction sequences that produce carbon dioxide and so return much carbon to a form that actively enters into life cycles once again.
25. The passage contains information that would answer which of the following questions about the carbon cycle?
I. What are some of the compounds that are broken down in the carbon cycle?
II. Why are some compounds that are involved in the carbon cycle less reactive than others?
III. What role do bacteria and fungi play in the carbon cycle?
I only
II only
III only
I and II only
I and III only
26. The author implies that which of the following is the primary reason that degradation is as important as synthesis to the smooth operation of the carbon cycle?
Most of the polymers and organic compounds found in the plant kingdom are chemically unstable.
The synthesis of some organic material deprives life processes of an energy source.
Decomposition permits the recycling of carbon that would otherwise be fixed in certain substances.
Many organisms cannot use plants as a source of food, but can feed on bacteria and fungi.
Bacteria and fungi could not survive if some carbon compounds were not degraded.
27. The author s contention about the importance of bacteria and fungi in the production of energy for life processes would be most clearly strengthened if which of the following were found to be true?
Both aerobes and anaerobes provide sources of energy through the decomposition of organic material.
Most compounds containing carbon are unavailable as energy sources except to some bacteria and fungi.
Bacteria and fungi break down inert material in ways that do not involve oxidation.
Many compounds remain inert, even in the presence of bacteria and fungi.
Bacteria and fungi assist in the synthesis of many organic compounds.
