3. Toxicologist: A survey of oil-refinery workers who
work with MBTE, an ingredient currently used
in some smog-reducing gasolines, found an
alarming incidence of complaints about
headaches, fatigue, and shortness of breath.
Since gasoline containing MBTE will soon be
widely used, we can expect an increased
incidence of headaches, fatigue, and shortness
of breath.
Each of the following, if true, strengthens the
toxicologist’s argument EXCEPT:
(A) Most oil-refinery workers who do not work with
MBTE do not have serious health problems
involving headaches, fatigue, and shortness
of breath.
(B) Headaches, fatigue, and shortness of breath are
among the symptoms of several medical
conditions that are potentially serious threats
to public health.
(C) Since the time when gasoline containing
MBTE was first introduced in a few
metropolitan areas, those areas reported an
increase in the number of complaints about
headaches, fatigue, and shortness of breath.
(D) Regions in which only gasoline containing
MBTE is used have a much greater incidence
of headaches, fatigue, and shortness of breath
than do similar regions in which only MBTEfree
gasoline is used.
(E) The oil-refinery workers surveyed were
carefully selected to be representative of the
broader population in their medical histories
prior to exposure to MBTE, as well as in
other relevant respects.

To prevent harbor porpoises from getting tangled in its nets and suffocating, a fishing company installed acoustic alarms on all its boats that fish in waters off Massachusetts.  The sound emitted temporarily disorients the porpoises and frightens them away.  Since the installation of the alarms, the average number of porpoises caught in the company's nets has dropped from eight to one per month.  The alarms, therefore, are saving the lives of harbor porpoises in those waters.
Which of the following is an assumption on which the argument depends?
(A) The use of acoustic alarms increases the number of commercial fish caught by the fishing company's boats.
(B) When disoriented, harbor porpoises are not significantly more likely to be killed by other boats.
(C) Environmentalists advocate the use of acoustic alarms as a means of protecting the harbor porpoise population.
(D) The alarms were installed at the time of year when harbor porpoises are most plentiful in the Massachusetts waters.
(E) The cost of installing acoustic alarms on fishing boats is less than the cost of repairing nets damaged by harbor porpoises.

An advertising agency must leave its office building.  To save overhead costs, it is considering setting up a "virtual office" instead of moving to an adjacent office building.  Employees will do their work on computers, as they do now, but will do so at home, sharing their work with colleagues by communicating text and designs to colleagues' computers through telephone lines, receiving typed comments, and then revising the work until it is satisfactory.
Which of the following, if true, indicates a disadvantage of the virtual office plan?
(A) The agency can move its computers and associated equipment into employees' homes without purchasing any new equipment or requiring employees to purchase such equipment.
(B) To reach the current office building and return home, employees spend an average of one and a half hours per day commuting, usually in heavy traffic.
(C) The employees of the advertising agency are accustomed to autonomy in monitoring their own progress and productivity.
(D) Employees would be able to adapt quickly to using computers in a virtual office setting, since employees' current use of computers to produce designs requires a high level of skill.
(E) Expressions and gestures in face-to-face exchanges are an important aid to employees in gauging the viability of new ideas they have proposed.

The symptoms that United States President Zachary Taylor began showing five days before his death are consistent with arsenic poisoning.  Recent examination of Taylor's bones, however, revealed levels of arsenic comparable to those found in the bones of Taylor's contemporaries.  These levels are much lower than the levels of arsenic that remain in the bones of arsenic poisoning victims who live for more than a day after ingesting a lethal dose of the poison.
Which of the following is most strongly supported by the statements given?
(A) The symptoms that Taylor began showing five days before his death are consistent with poisoning other than arsenic poisoning.
(B) Taylor's death was not the result of any kind of poisoning.
(C) The symptoms that Taylor began showing five days before his death were not caused by a lethal dose of arsenic.
(D) The symptoms that Taylor began showing five days before his death grew more severe each day.
(E) It is unusual for a person who has ingested a lethal dose of arsenic to survive for more than a day.

Paleontologist: About 2.8 million years ago, many species that lived near the ocean floor suffered substantial population declines.  These declines coincided with the onset of an ice age.  The notion that cold killed those bottom-dwelling creatures outright is misguided, however; temperatures near the ocean floor would have changed very little.  Nevertheless, the cold probably did cause the population declines, though indirectly.  Many bottom-dwellers depended for food on plankton, small organisms that lived close to the surface and sank to the bottom when they died.  Most probably, the plankton suffered a severe population decline as a result of sharply lower temperatures at the surface, depriving many bottom-dwellers of food.
In the paleontologist's reasoning, the two portions in boldface play which of the following roles?
(A) The first introduces the hypothesis proposed by the paleontologist; the second is a judgment offered in spelling out that hypothesis.
(B) The first introduces the hypothesis proposed by the paleontologist; the second is a position that the paleontologist opposes.
(C) The first is an explanation challenged by the paleontologist; the second is an explanation proposed by the paleontologist.
(D) The first is a judgment advanced in support of a conclusion reached by the paleontologist; the second is that conclusion.
(E) The first is a generalization put forward by the paleontologist; the second presents certain exceptional cases in which that generalization does not hold.

premise: MBTE will be widely used
conclusion: incidence of headaches, fatigue, and shortness of breath will increase
Q:support EXCEPT
prephrase: support EXCEPT again; relationship between the MBTE and complaints--->MBTE causes increase of incidence
1. A survey' raliability ; 2, whether has casual relationship 3. other facotrs happened at the same time
(A) Most oil-refinery workers who do not work with
MBTE do not have serious health problems
involving headaches, fatigue, and shortness
of breath.------strengthen;无因无果的例证
(B) Headaches, fatigue, and shortness of breath are
among the symptoms of several medical
conditions that are potentially serious threats
to public health.-----irrelevant; the argument concerns on the whether MBTE can lead to the incidence; so the origin of these symtoms has no bearing on the point.分析错了the author offers up possible alternate causes for the symptoms. These alternate causes would weaken the argument, and therefore this is the
correct answer.
(C) Since the time when gasoline containing
MBTE was first introduced in a few
metropolitan areas, those areas reported an
increase in the number of complaints about
headaches, fatigue, and shortness of breath.----有因有果的例证establish casual relationship
(D) Regions in which only gasoline containing
MBTE is used have a much greater incidence
of headaches, fatigue, and shortness of breath
than do similar regions in which only MBTEfree
gasoline is used.-------strengthen; esatblish causual relationship
(E) The oil-refinery workers surveyed were
carefully selected to be representative of the
broader population in their medical histories
prior to exposure to MBTE, as well as in
other relevant respects.-----strengthen; this statement confirms the reliability of the survey thus strengthen the argument
