逻辑思维训练题型
1. the ice on the front windshield of the car had formed when moisture condensed during the
night.
the
ice
melted
quickly
after
the
car
was
warmed
up
the
next
morning
BECause
the
defrosting vent, which blows only on the front windshield, was turned on full force.
which of the following, if true, most seriously jeopardizes the validity of the explanation
for the speed with which the ice melted?
a) the side windows had no ice condensation on them
b) even though no attempt was made to defrost the back window, the ice there melted at
the same rates as did the ice on the front windshield.
c)
the
speed
at
which
ice
on
a
window
melts
increases
as
the
temperature
of
the
air
blown on the window increases.
d)
the
warm
air
from
the
defrosting
vent
for
the
front
windshield
cools
rapidly
as
it
dissipates through out the rest of the car.
e) the defrosting vent operates efficiently even when the heater, which blows warm air
toward the feet or faces of the driver and passengers, is on.
2. pandas are rapidly disappearing from the wild. therefore, in order to preserve the species,
existing pandas should be captured and placed in zoos around the world.
which of the following, if true, casts doubt on the conclusion drawn above?
a)
when
in
captivity,
pandas
typically
produce
more
young
than
they
do
in
their
native
habitat
b)
newborn
pandas
in
zoos
are
not
likely
to
die
from
infectious
diseases,
whereas
newborn pandas in the wild are likely to die from these diseases.
c)
sufficient
quantities
of
b
amboo,
the
panda’s
only
food
cannot
be
made
available
outside the panda’s native habitat.
d) many zoos are eager to increase their stock of rare and exotic animals, but there are
not enough pandas for all the zoos that want one.
e) pandas in zoos have as many offspring that survive to adulthood as do pandas in the
wild.
3. over the past fifteen years, the largely urbanized northeastern united states has shown
more and more the influence of the southwestern portion of the county. once, very few people
in new york city could be found sorting cowboy boots and stetson hats, and no major radio
station boasted twenty-four-hour-a-day programming of country and western music. the latest
development is the rapid proliferation of restaurants serving chili, nachos, burritos, and other
tex-mex dishes.
the passage above makes which of the following assumptions?
a)
the
lifestyle
of
people
in
the
northeast
has
been
enriched
by
the
influence
of
the
southwestern states.
b) most residents of the southwestern states regularly eat at tex-mex restaurants.
c)
over
the
last
fifteen
years,
residents
of
the
southwestern
united
states
have
increasingly adopted lifestyles similar to those of the northeast.
d) tex-mex dishes are an element of the regional cuisine of the southwestern states.
e) people in the northeastern united states eat out more frequently than they did fifteen
years ago.
4.
popular
culture
in
the
united
states
has
become
europeanized
to
an
extent
unimaginable twenty-five years ago. not many people then drank wine with meals, and no one
drank
important
mineral
water.
no
idea
would
have
been
more
astonishing
than
that
americans would pay to watch soccer games. such thoughts arise because of a report that
the
american
association
of
state
highway
and
transportation
officials
has
just
adopted
a
proposal to develop the country’s first comprehensive interstate system of routes for bicycles.
which of the following inferences is best supported by the passage?
a) long-distance bicycle routes are used in europe.
b) drinking imported mineral water is a greater luxury than drinking imported wine.
c) united states culture has benefited from exposure to foreign ideas.
d) most europeans make regular use of bicycles.
e) the influence of the united states on european culture has assumed unprecedented
proportions in the last twenty-five years.
5. “on the whole,” ms. winson remarked, “enginee
ring students are lazier now than they
used to be. i know because fewer and fewer of my students regularly do the work they are
assigned.”
the conclusion drawn above depends on which of the following assumptions?
a)
engineering
students
are
working
less
because,
in
a
booming
market,
they
are
spending more and more time investigating different job opportunities.
b) whether or not students do the work they are assigned is a good indication of how lazy
they are.
c) engineering students should work harder than students in less demanding fields.
d) ms. winson’s students are doing less work because ms. winson is not as effective a
teacher as she once was.
e) laziness is something most people do not outgrow.
6. the average life expectancy for the united states population as a whole is 73.9 years,
but children born in hawaii will live an average of 77 years, and those born in louisiana, 71.7
years. if a newlywed couple from louisiana were to begin their family in hawaii, therefore, their
children
would
be expected
to
live
longer
than
would
be
the
case
if
the
family remained
in
louisiana.
which
of
the
following
statement,
if
true,
would
most
significantly
strengthen
the
conclusion drawn in the passage?
a) as population density increases in hawaii, life expectancy figures for that state are
likely to be revised downward.
b) environmental factors tending to favor longevity are abundant in hawaii and less
numerous in louisiana.
c)
twenty-five
percent
of
all
louisianaians
who
move
to
hawaii
live
longer
than
77
years.
d)
over
the
last
decade,
average
life
expectancy
has
risen
at
a
higher
rate
for
louisianaians than for hawaiians.
e) studies show that average life expectancy for hawaiians who move permanently to
louisiana is roughly equal to that of hawaiians who remain in hawaii.
7.
a
conservation
group
in
the
united
states
is
trying
to
change
the
long-standing
image
of
bats
as
frightening
creatures.
the
group
contends
that
bats
are
feared
and
persecuted solely because they are shy animals that are active only at night.
which of the following, if true, would cast the most serious doubt on the accuracy of
the group’s contention?
a)
bats are
steadily
losing natural
roosting
places
such as
caves
and hollow
trees
and are thus turning to more developed areas for roosting.
b) bats are the chief consumers of nocturnal insects and thus can help make their
hunting territory more pleasant for humans.
c) bats are regarded as frightening creatures not only in the united states but also in
europe, africa, and south america.
d)
raccoons
and
owls
are
shy
and
active
only
at
night;
yet
they
are
not
generally
feared and persecuted.
e)
people
know
more
about
the
behavior
of
other
greatly
feared
animal
species,
such as lions, alligators, and snakes, than they do about the behavior of bats.
8.
in
the
aftermath
of
a
worldwide
stock-market
crash,
country
t
claimed
that
the
severity
of
the
stock- market
crash
it
experienced
resulted
from
the
accelerated
process
of
denationalization many of its industries underwent shortly before the crash.
which
of
the
following,
if
it
could
be
carried
out,
would
be
most
useful
in
an
evaluation of country t’s assessment of the causes of the severity of its stock
-market crash?
a) calculating the average loss experienced by individual traders in country t during
the crash.
b) using economic theory to predict the most likely date of the next crash in country
t.
c) comparing the total number of shares sold during the worst days of the crash in
country t to the total number of shares sold in country t just prior to the crash.
d)
comparing
the
severity
of
the
crash
in
country
t
to
the
severity
of
the
crash
in
countries
otherwise
economically
similar
to
country
t
that
have
not
experienced
recent
denationalization.
e)
comparing
the
long- term
effects
of
the
crash
on
the
purchasing
power
of
the
currency
of country
t
to
the
immediate, more severe
short-term effects
of the crash
on
the
purchasing power of the currency of country t.
9. increase in the level of high-density lipoprotein (hdl) in the human bloodstream
lower bloodstream-cholesterol levels by increasing the
body’s capacity to rid itself of excess
cholesterol. levels of hdl in the bloodstream of some individuals are significantly increased by
a program of regular exercise and weight reduction.
which of the following can be correctly inferred from the statement above?
a) individuals who are underweight do not run any risk of developing high levels of
cholesterol in the bloodstream.
b) individuals who do not exercise regularly have a high risk of developing high levels
