NEW QUESTION 148
What does the word patent mean to you? Does it strike you as being something rather remote from your interests? If it does, stop and think a moment about some of the commonplace things that you use every day, objects that you take for granted as part of the world around you. The telephone, radio, television, the automobile, and the thousand and one other things (even the humble safety pin) that enrich our lives today once existed only as ideas in the minds of men. If it had not been possible to patent their ideas and thus protect them against copying by others, these inventions might never have been fully developed to serve mankind. If there were no patent protection there would be little incentive to invent and innovate, for once the details of an invention became known, hordes of imitators who did not share the inventor's risks and expenses might well flood the market with their copies of his product and reap much of the benefit of his efforts.
The technological progress that has made America great would wither rapidly under conditions such as these. The fundamental principles in the U S patent structure came from England. During the glorious reign of Queen Elizabeth I in England, the expanding technology was furthered by the granting of exclusive manufacturing and selling privileges to citizens who had invented new processes or tools- a step that did much to encourage creativity. Later, when critics argued that giving monopoly rights to one person infringed on the rights of others, an important principle was added to the patent structure: The Lord Chief Justice of England stated that society had everything to gain and nothing to lose by granting exclusive privileges to an inventor, because a patent for an invention was granted for something new that society never had before. Another basic principle was brought into law because certain influential people in England had managed to obtain monopoly control over such age-old products as salt, and had begun charging as much as the traffic would bear. The public outcry became so great that the government was forced to decree that monopoly rights could be awarded only to those who created or introduced something really unique. These principles are the mainstays of our modern patent system in the United States. In colonial times patent law was left up to the separate states. The inconsistency, confusion, and unfairness that resulted clearly indicated the need for a uniform patent law, and the men who drew up the Constitution incorporated one. George Washington signed the first patent law on April 10,1790, and less than four months later the first patent was issued to a man named Samuel Hopkins for a chemical process, an improved method of making potash for use in soapmaking. In 1936 the Patent Office was established as a separate bureau. From the staff of eight that it maintained during its first year of operation it has grown into an organization of over 2500 people handling more than 1600 patent applications and granting over
1000 every week. The Patent Office in Washington D C, is the world's largest library of scientific and technical data, and this treasure trove of information is open for public inspection. In addition to more than
3 million U S patents, it houses more than 7 million foreign patents and thousands of volumes of technical literature. Abraham Lincoln patented a device to lift steam vessels over river shoals, Mark Twain developed a self-pasting scrapbook, and millionaire Cornelius Vanderbilt invented a shoe-shine kit. A patent may be granted for any new and useful process, machine, article of manufacture, or composition of matter ( a chemical compound or combinations of chemical compounds), or any distinct and new variety; of plant, including certain mutants and hybrids. The patent system has also helped to boost the wages of the American worker to an unprecedented level; he can produce more and earn more with the computer, adding machines, drill press or lathe. Patented inventions also help keep prices down by increasing manufacturing efficiency and by stimulating the competition that is the foundation of our free enterprise system. The decades of history have disclosed little need for modification of the patent structure. Our patent laws, like the Constitution from which they grew, have stood the test of time well. They encouraged the creative processes, brought untold benefits to society as a whole, and enabled American technology to outstrip that of the rest of the civilized world.
What is the main idea of this passage?
- A. The patent system in England has been influential in American patent development.
- B. The Constitution protects the patent system.
- C. The patent system encourages free enterprise.
- D. Patented inventions protect the inventor, free enterprise, and the creative process.

NEW QUESTION 150
Robert Philip argues that the advent of recorded music has directed performance style into a search for greater precision and perfection, with a consequent loss of spontaneity and warmth. Various expressive devices once common in classical music have been almost outlawed, including portamento (sliding from one note to another on a stringed instrument), playing the piano with the hands not quite synchronized, and flexibility of tempo.
Philip fully documents these changes. However, other forces independent of recording were also at work. For example, the freedom of tempo so valued by Philip was. in its time, both a necessary expedient and disastrously abused. Recording alone did not cause the reaction against it. although hearing a particularly unintelligent use of it on disc may have reinforced the prejudice.
A criticism of Philip implied by the passage is that he
- A. attributes a change in performance style to a single cause
- B. limits his discussion of performance style to classical music
- C. exaggerates the extent of a change in performance style
- D. ignores unintelligent uses of certain performance techniques
- E. values performance techniques that have lost their effectiveness
Answer: D
NEW QUESTION 151
One reason researchers have long believed that Mars never enjoyed an extensive period of warm and wet climate is that much of the surface not covered by wind-borne dust appears to be composed of unweathered material If water flowed for an extended period, researchers reasoned, it should have altered and weathered the volcanic minerals, creating clays or other oxidized, hydrated phases (minerals that incorporate water molecules in their crystal structure).
It turns out. though, that the scientists were not looking closely enough. New high-resolution mapping data and close-up surface studies have revealed clays and other hydrated minerals in many regions The clay deposits are scattered all over, in ancient volcanic surfaces and heavily cratered highland regions, some of which have apparently been exposed by erosion only recently.
It can be inferred from the passage that the author would agree with which of the following statements regarding the reasoning discussed in the highlighted sentence?
- A. It provides the basis for an explanation of why water on Mars has been difficult to find until recently C It correctly identifies a consequence of water flowing on the Martian surface.
- B. It results in a new understanding of how water and volcanic materials interact on Mars.
- C. It fails to take into account the impact of wind-borne dust on the Martian surface
- D. It is based on an underestimation of the extent to which flowing water would alter volcanic materials on Mars

NEW QUESTION 157
Radiative forcings are changes imposed on the planetary energy balance; radiative feedbacks are changes induced by climate change. Forcings can arise from either natural or anthropogenic causes. For example, the concentration of sulfate aerosols in the atmosphere can be altered by volcanic action or by the burning of fossil fuels. The distinction between forcings and feedbacks is sometimes arbitrary; however, forcings are quantities normally specified in global climate model simulations, while feedbacks are calculated quantities. Examples of radiative forcings are greenhouse gases (such as carbon dioxide and ozone), aerosols in the troposphere, and surface reflectivity. Radiative feedbacks include clouds, water vapor in the troposphere, and sea-ice cover. The effects of forcings and feedbacks on climate are complex. For example, clouds trap outgoing radiation, thus providing a warming influence, while also reflecting incoming solar radiation and, thereby, providing a cooling influence. Current measurements indicate that the net effect of clouds is to cool the earth. However, scientists are unsure if the balance will shift in the future as the atmosphere and cloud formation are altered by the accumulation of greenhouse gases. Similarly, the vertical distribution of ozone affects both the amount of radiation reaching the earth's surface and the amount of reradiated radiation that is trapped by the greenhouse effect. These two mechanisms affect the earth's temperature in opposite directions.
Based solely on the information in the passage, which of the following research methods, if implemented, would be most likely to yield a more accurate prediction of the extent and direction of the greenhouse effect?
- A. Isolating ozone changes caused specifically by anthropogenic factors
- B. Accounting for the altitude at which cloud formations appear
- C. Measuring variations in cloud density in relation to air temperature
- D. Monitoring radiative feedbacks and forcings over a longer time period
- E. Isolating the cooling influence1 of ozone changes from their warming influence
Answer: E
Explanation:
Explanation/Reference:
Explanation:
According to the passage, a given vertical distribution of ozone affects atmospheric temperatures in both directions at once. Accordingly, by isolating the cooling influence of a given distribution of ozone from its warming influence, scientists might better predict whether changes in the vertical distribution of ozone will have a net cooling or a net warming effect.

NEW QUESTION 159
Even the most complex models used in fishery management are cartoons of reality. They reduce hundreds of links in food webs to a handful and inadequately represent processes operating over space. Many of their assumptions are as flawed today as those of the simplest models of the past. Fish stocks, for one. are still assumed to be populations of a species that are isolated from one another. Yet many populations mix at their edges and some even migrate through areas occupied by other populations. Furthermore, the more complex models suffer from a "crisis of complexity"-more is really less. Adding layers of detail, each carrying its own set of assumptions, produces instability. The model's behavior becomes erratic, and conclusions drawn from it can be downright misleading.
In the context of the passage, the highlighted portion serves to
- A. question a finding
- B. recommend a reformulation
- C. demonstrate an oversimplification
- D. confirm a prediction
- E. anticipate an objection
Answer: C
