Spread across the United States are about 500,000 doctors, cheeked by jowl, in the ePi
Z
big cities and thin on the ground in isolated small towns. In June 1986, the secretary i:{:xKiC a
of health and human services, Dr. Otis Bowen, passed on a view of his experts: 5%-15% 5e
)i!;7Uv
of America’s 500,000 doctors should be candidates for disciplinary action, many of ZDfS0]0F
them because of drug taking or alcoholism. Others give their patients poor care y1nP F&_
because they are senile, incompetent, guilty of misconduct or out of touch with ;
tm3B2
developments in medicine. Ls(&HOK[p
The granting, or withdrawal, of licenses to practice is in the hands of state medical qR_SQ
VN
boards, but they are overwhelmed with complaints and lack the money to handle even 0:jsV|5B8
a fraction of them. Recently, however, things have been changing. In 1985, 406 PMQb\%iE"
doctors lost their licenses (compared with 255 in 1984), nearly 500 were placed on BL7>dZOa
probation and nearly 1,000 received reprimands or had their right to practice curtailed. NWeV>;lh9
The federal inspector general demanded, and won the right far the states and the 4_WH
6Z

unsatisfactory. . c#90RP
Yet putting these powers into practice is proving to be far from easy. Of the 35 haN"/C^
doctors so far denied reimbursement from Medicare, almost all work in lightly 9#ZzE/
populated rural areas. On March 27th, their indignation and that of their patients were BF>T*Z-Ki
a sympathetic hearing by the Senate Finance Committee. Rural doctors may not be as av"Dljc
up to date as those in the big towns, but they are often the only source of medical help =P1RdyP
for miles around and their patients are loyal to them. Members of the review boards, PKl]GegP
which are paid by the government, insist, however, that elderly and poor people Tq.MubaO
should not be forced to receive (and the state to pay for) inferior care. An innovation is on the horizon in Texas, the most under-doctored state in the $#D

Questions 26 to 30 are based on the following passage. D@sx`H(
Bacteria are extremely small living things. While we measure our own sizes in 4 _c:Vl
inches or centimeters, bacterial size is measured in microns. One micron is a e"v[)b++Y
thousandth of a millimeter: a pinhead is about a millimeter across. Rod-shaped "tg\yem
bacteria are usually from two to four microns long, while rounded ones are generally ^t/'dfF
one micron in diameter. Thus, if you enlarged a rounded bacterium a thousand times, <'o 'H
it would be just about the size of a pinhead. An adult human magnified by the same {"gyXDE1
amount would be over a mile (1.6 kilometers) tall. 4$q)
e<-
Even with an ordinal microscopy, you must look closely to see bacteria. Using a NbQMWU~7
magnification of 100 times, one finds that bacteria are barely visible as tiny rods or k^'d@1z;C
dots. One cannot make out anything of their structure. Using special stains, one can b.%B;qB
see that some bacteria have attached to them wavy-looking “hairs” called flagella. f!uA$uLc
Others have only one flagellum. The flagella rotate, pushing the bacteria through the <L!~f`nH2
water. Many bacteria lack flagella and cannot move about by their own power, while others can glide along over surfaces by some little-understood mechanism.
]U^d 1&k
From the bacterial point of view, the world is a very different place from what it is gn[$;*932z
to humans. To a bacterium, water is as thick as molasses is to us. Bacteria are so small 5u
u2 _B_L
that they are influenced by the movements of the chemical molecules around them. |Ad6~E+aL-
Bacteria under the microscope, even those with no flagella, often bounce about in Ck/_UY|
the water. This is because they collide with the water molecules and are pushed this m|e*Jc
way and that. Molecules move so rapidly that within a tenth of a second the molecules E^EU+})Ujr
around a bacterium have all been replaced by new ones; even bacteria without flagella J?n)FgxS
are thus constantly exposed to a changing environment. &\6`[# bT
26. Which of the following is the main topic of the passage? 23u1nU[0
A. The characteristics of bacteria # 1qVFU
B. How bacteria reproduce _'v }=:X

Questions 31 to 35 are based on the following passage. !wb~A0m
Although, recent years have seen substantial reductions in noxious pollutants from Y /ac}q
individual motor vehicles, the number of such vehicles has been steadily increasing. vyx\N{
Consequently, more than 100 cities in the United States still have levels of carbon 0qd;'r<
monoxide, particulate matter, and ozone (generated by photochemical, reactions with .]ZuG
hydrocarbons from vehicle exhaust) that exceed legally established limits. There is a Py2
5k 0j!
growing, realization that the only effective way to achieve, further reductions in $}nUK~$GSv
vehicle emissions-short of a massive shift away from the private automobile-is to =&b$W/l)0
replace conventional diesel fuel and gasoline with cleaner burning fuels such as >8fz ?A
compressed natural gas liquefied petroleum gas, ethanol, or methanol. e}4^N1'd/
All of these alternatives are carbon-based fuels whose molecules are smaller and #M9D"
<pn}
simpler than those of gasoline. These molecules burn more cleanly than gasoline, in +=H>s;B
part because they have fewer, if and, carbon-carbon bonds, and the hydrocarbons they ^FMa8;'o
do emit are less likely to generate ozone. The combustion of large molecules, which have multiple carbon-carbon bonds, involves a more complex series of reactions. '%RK KA
These reactions increase the probability of incomplete combustion and are more likely
nIDsCu=A
to release uncombusted and photochemically active hydrocarbon compounds into the k42ur)pb
atmosphere. On the other hand, alternative fuels do have drawbacks. Compressed DMxS-hl
natural gas would require that vehicles have a set of heavy fuel tanks-a serious \lakT_x
liability in terms of performance and fuel efficiency and liquefied petroleum gas faces 2GKU9cV*`
fundamental limits on supply. m^x\@!N:(
Ethanol and methanol, on the other hand, have important advantages over other PXu<4VF
carbon-based alternative fuels; they have hither energy content per volume and would
Vh2/Ls5
require minimal changes in the existing network for distributing motor fuel. Ethanol is HN~4-6[q
commonly used as a gasoline supplement, but it is currently about twice as expensive |Ge/|;.v`
as methanol, the low cost of which is one of its attractive features. Methanol’s most SF7b1jr
attractive feature , however, is that it can reduce by about 90 percent the vehicle wJR i;fvi
emissions that form ozone, the most serious urban air pollutant. r~fl=2>yQ
Like any alternative fuel, methanol has its critics. Yet much of the criticism is "/Q(UV<d
based on the use of “gasoline clone” vehicles that do not incorporate even the simplest UpseU8Wo
design improvements that are made possible with the use of methanol. It is true, for jLS]^|
example, that a given volume of methanol provides only about one-half of the energy o4'4H y
that gasoline and diesel fuel do; other things being equal, the fuel tank would have to @=#s~ 3
be somewhat larger and heavier. However, since methanol-fueled vehicles could be [%,=0P}
designed to be much more efficient than “gasoline clone ” vehicles fueled with
mFoK76
methanol, they would need comparatively less fuel. Vehicles incorporating only the ~)IJE+e>}
simplest of the Engine improvements that methanol makes feasible would still UkbQ'P+oS
contribute to an immediate lessening of urban air pollution. Jd2Y)
31. The author of the passage is primarily concerned with __________. iwjl--)@K
A. countering a flawed argument that dismisses a possible solution to a problem. 9l_?n@
B. reconciling contradictory points of view about the nature of a problem. K}3"K C
C. identifying the strengths of possible solutions to a problem. xWb?i6)z&
D. discussing a problem and arguing in favor of one solution to it. 5f@YrTO[@
32. According to the passage, incomplete combustion is more likely to occur with n]c,0N

33. The passage suggests which of the Following about air pollution? cD@lorj
A. Further attempts to reduce emissions from gasoline-fueled vehicles will not )^#Zg8L
help lower urban air-pollution levels. L\CM);y
B. Attempts to reduce the pollutions that an individual gasoline-fueled vehicle G/44gKl
emits have been largely unsuccessful. vm}.gQ
C. Few serious attempts have been made to reduce the amount of pollutants FGhrf
emitted by gasoline-fueled vehicles. ]!o,S{a&

of urban air pollution. <[l}^`IC^4
34. The author describes which of the following as the most appealing feature of r9*H-V$
methanol? 2_v+q
A. It is substantially less expensive than ethanol. %-po6Vf

system. Y,}43a0A
C. It has a higher energy content than other alternative fuels. D. Its use would substantially reduce ozone levels. ,?~,"IQyi[
35. It can be inferred that the author of the passage most likely regards the criticism #N}}8RL
of methanol in the last paragraph as __________. vJ}
A. flawed because of the assumptions on which it is based. m|FONQ,@D
B. inapplicable because of an inconsistency in the critics’ arguments. <{Wa[

C. misguided because of its exclusively technological focus. ` &7?+s
D. invalid because it reflects the personal bias of the critics. 1K',Vw_
Questions 36 to 40 are based on the following passage. xl=|]8w
Tests of reaction times seemed to back up the notion that the two hemispheres vAxtNRS
differed in their processing styles. Researchers used to believe that an image goes to [c )\?MWW
one hemisphere first, and then to the opposite side of the brain. If the nature of the uoc-qmm
stimulus and the preference of the hemisphere match up, then the person can respond flt
cdA
slightly more quickly and accurately in identifying the local or global image. I@v.Hqg+7
Still more startling, researchers found that the same appeared to hold for the brains sRI8znus
of chimps and perhaps other primates. The assumption has always been that 1nG"\I5N}
handedness and brain asymmetry are strictly human traits --- part of the great brain s7LX
reorganization that allowed our ancestor to use tools, speak and perhaps even think KO$8l
Mm$
rationally. But handedness is now widely claimed for primates and even birds, #]^`BQ>
amphibians and whales. And in the past few years, some psychologists have tested ^E*C~;^S
chimps and baboons and suggested their two hemispheres also differ in processing /tP
style. X)5O@"4 ?
Now researchers have come to see the distinction between the two hemispheres as zaPR>:r0
a subtle one of processing style, with every mental faculty shared across the brain, and r${a
S@F
each side contributing in a complementary, not exclusive, fashion. A smart brain y+h=x4t
became one that simultaneously grasped both the foreground and the background of E
atDT*!
the moment ]z NL+]1_
The next problem was to work out exactly how the brain manages to produce Os+=}
these two contrasting styles. Many researchers originally looked for the explanation in qILr+zH
a simple wiring difference within the brain. This theory held that neurons in the left |[ofc!/
cortex might make sparse, short-range connections with their neighbors, while cells !{\c`Z<#
on the other side would be more richly and widely connected The result would be that ]ORat.*0[T
the representation of sensations and memories would be confined lo smallish, discrete ZrBxEf
$f
areas in the left hemisphere, while exactly the same input to a corresponding area of a[
De
the right side would form a sprawling even impressionistic pattern of activity. ](pD<FfS]'
Supporters of this idea argued that these structural differences would explain why bN)?szh&Y
