2, Telephone companies are promoting voice mail as an alternative to the answering machine. By recording messages from callers when a subscriber does not have access to his or her telephone， voice mail provides a service similar to that of an answering machine. The companies promoting this service argue that it will soon make
answering machines obsolete， since it is much more convenient， more flexible， and less expensive than an answering machine.
which one of the following， if true， most calls into question the argument made by the companies promoting voice mail？
A, Unlike calls made to owners of answering machines， all telephone calls made to voice－mail subscribers are completed， even if the line called is in use at the time of the call.
B, The surge in sales of answering machines occurred shortly after they were first introduced to the electronics market.
C, Once a telephone customer decides to subscribe to voice mail， that customer can cancel the service at any time.
D, Answering machines enable the customer to hear who is calling before the
customer decides whether to answer the telephone，while a service voice mail does not provide.
E, The number of messages a telephone answering machine can record is limited by the length of the magnetic tape on which calls are recorded
The following 2 questions are based on the reading material:
The simple facts are these： the number of people killed each year by bears is about the same as the number of people killed by lightning of golf courses. And the number of people killed by lightning on golf courses each year is about the same as the number of people electrocuted by electric blenders. All the horrible myths and
gruesome stories aside， therefore a grizzly bear is in fact about as dangerous as an electric blunderers game of golf.
3. Which of the following can be reasonably inferred from the reading material? A, Most incidents involving grizzly bears are fatal.
B, Grizzly bears are no longer the danger they once were.
C, The number of fatalities per year is an adequate indication of something?s dangerousness.
D, A golf course is a particularly dangerous place to be in a thunderstorm. E, Something is dangerous only if it results in death in the majority of cases.
4, Which one of the following， if true， would most effectively undermine the author?s argument？
A, Although the number of people killed by lightning on golf courses each year is very small， the total number of lightning fatalities is many times greater.
B, Electric blenders are among the safest housed hold appliances; were the author to compare fatalities from electrical appliances in general， she would get a much higher figure.
C, Most people would rather take their chances with benders and golf games than with grizzly bears.
D, Bears in general including black， brown， and cinnamon bears， as well as grizzly bears kill many more people than do electric blenders.
E, Statistics show that the number of times people use electric blenders each year exceeds the number of times people play golf each year， which in turn far exceeds the number of contacts people have with grizzly bears each year.
5,Drivers with a large number of demerit points who additionally have been convicted of a serious driving-relative offense should be sentenced to jail rather than be forced to receive driver reeducation, since to do otherwise would be to allow a crime to go unpunished.
What can be inferred from the passages about the re-education to drivers? A, it is free to all drivers.
B, it is widely used in recent practice.
C, it is a good chance for drivers to know the dangers of illegal driving. D, it is only applied to drivers who made offenses.
E, it is not a good way to punish drivers who used to make driving-relative offenses.
6, Drivers with a large number of demerit points who additionally have been
convicted of a serious driving-relative offense should either be sentenced to jail or be forced to receive driver reeducation, since to do otherwise would be to allow a crime to go unpunished. Only if such drivers are likely to be made more responsible drivers should driver re-education be recommended for them. Unfortunately, it is always almost impossible to make drivers with a large number of demerit points more responsible drivers.
If the editorialist's statements are true, they provide the most support for which one of the following?
(A) Drivers with a large number of demerit points who have been convicted of a serious driving-related offense should be sent to jail.
(B) Driver re-education offers the best chance of making drivers with a large number of demerit points responsible drivers.
(C) Driver re-education is not a harsh enough punishment for anyone convicted of a serious driving-related offense who has also received re-education. (D) Driver re-education should not be recommended for those who have committed no serious accidents.
(E) Drivers with a larger number of demerit points but no conviction for a serious driving-related offense should receive driver re-education rather than jail.
7, Amphibian populations are declining in numbers worldwide. Not coincidentally, the earth's ozone layer has been continuously depleted throughout the last 50 years. Atmospheric ozone blocks UV-B, a type of ultraviolet radiation that is continuously produced by the sun, and which can damage genes. Because amphibians lack hair, hide, or feathers to shield them, they are particularly vulnerable to UV-B radiation. In addition, their gelatinous eggs lack the protection of leathery or hard shells. Thus, the primary cause of the declining amphibian population is the depletion of the ozone layer.
What is the main characteristic of UV-B from the reading material? A, It can be hugely blocked by the ozone layer of the earth. B, Its? harm is more severe on a sunny day than on a rainy day.
C, It can cause negative effect on creatures who lack certain protection against it.
D, It is the main cause of the declining in numbers of amphibian.
E, It recently becomes severe since the ozone layer has been damaged by human.
8, Amphibian populations are declining in numbers worldwide. Not coincidentally, the earth's ozone layer has been continuously depleted throughout the last 50 years.

Because amphibians lack hair, hide, or feathers to shield them, they are particularly vulnerable to UV-B radiation. In addition, their gelatinous eggs lack the protection of leathery or hard shells. Thus, the primary cause of the declining amphibian population is the depletion of the ozone layer.
If true, which of the following statements is most likely to be selected by the writer as the evidence for his analyzing?
(A) Of the various types of radiation blocked by atmospheric ozone, UV-B is the only type that can damage genes.
(B) Amphibian populations are declining far more rapidly than are the populations of nonamphibian species whose tissues and eggs have more natural protection from UV-B.
(C) Atmospheric ozone has been significantly depleted above all the areas of the world.
(D) The natural habitat of amphibians has not become smaller over the past century.
(E) Amphibian populations have declined continuously for the last 50 years.
9, Quasars——celestial objects so far away that their light takes at least 500 million years to reach Earth——have been seen since 1963. For anything that far away to appear from Earth the way quasars do, it would have to burn steadily at a rate that produces more light than 90 billion suns would produce.
If the above statement is true, which of the following can be possibly inferred from the reading material?
A, The celestial objects which are not as far from the earth as quasars may not
necessarily burn steadily at a rate that produces more light than 90 billion suns would produce in order to be seen on the earth.
B, The further away the celestial objects are from the earth, the less light they need to produce.
C, The celestial objects which are further away from the earth than quasars must burn steadily at a rate that produces more light than 90 million suns would produce in order to be seen on the earth.
D, With advanced telescopic equipment, the celestial objects which are further away from the earth than quasars may not necessarily burn steadily at a rate that produces more light than 90 billion suns would produce in order to be seen on the earth. E, Before 1963, the limitation in equipment prevents people to see quasars on the earth.
10, More and more computer programs that provide solutions to mathematical
problems in engineering are being produced, and it is thus increasingly unnecessary for practicing engineers to focus on fundamental mathematical principles. Which of the following statement can be most effectively used as the supporting evidence for the above statement?
A, practicing engineers are all good at fundamental mathematical principles. B, computer programs are developing with time and cannot be out of date. C, all practicing engineers are skillful in using computer programs to solve mathematical problems.
D, practicing engineers? ability to use computer programs effectively is based on a full understanding of fundamental mathematical principles.
E, fundamental mathematical principles are not relevant to mathematical problems which are frequently met by practicing engineers.
11, More and more computer programs that provide solutions to mathematical
problems in engineering are being produced, and it is thus increasingly unnecessary for practicing engineers to have thorough understanding of fundamental mathematical principles. Consequently, in training engineers who will work in industry, less emphasis should be placed on mathematical principles, so that space in the engineering curriculum will be available for other important subjects.
Which one of the following, if true, most seriously weakens the argument given for the recommendation above?
(A) The effective use of computer program that provide solutions to
mathematical problems in engineering requires an understanding of mathematical principles.
