IV. GUIDED CLOZE (10 PTS): Read the texts below and decide which answer best

fits each space.
Passage A
What is the (41)
between an argument and a quarrel? Look the word "quarrel" up in
a dictionary and you will find it defined as an "angry argument". It seems that "angry" is
the key word here. Both quarrelling and arguing involve disagreements but it is only during
the former that we become angry or upset. We may raise our voices or even display
aggressive behaviour when quarrelling, (42)
in an argument, we maintain a (43)
tone of voice and refrain from physically
threatening our opponent. An argument is a discussion or debate in which two or more
people put forward diferent or opposing views. They may not be personally concerned in
the issues under discussion. (44)
, the process is an objective, intellectual one.
Evidence and (45)
may be used in order to support the speaker's point of view and
possibly to convince the other(s). A quarrel, however, is personal, bound up with the ego
and the participants' sense of self. For instance, things that the opponent may have said or
done in the past are often dragged (46)
at random as and when they occur to the
speaker, in
(47)
the logical marshalling of ideas which arguing involves. A quarrel may result
from a (48)
of personalities, may hurt the participants and may be sincerely regretted
afterwards. Given that there are hot-tempered people around, they may get carried away
in an argument so that it degenerates
(49)
quarrel, but it should, generally speaking, be a dispassionate exchange of views
(50)

a shouting match.
41. A. diferential
B. divergence
C. discrepancy

B. other than
C. more than
D. rather
than Passage B
Prime numbers have been well known to mathematicians for (51)
considerable
time, in fact since Eratosthenes discovered the principle in the third century BCE. These
are numbers which can only be divided by one and by themselves, such as three and five,
and are important (52)
they are the components of integers – (53) numbers.
Recently, there has been a breakthrough in understanding these unusual (54) .
This advance concerns the Twin Prime Conjecture – an idea that there are an infinite
number of prime number pairs which are separated from each other by only two numbers,
for example 11 and 13; 17 and 19; 29 and 31; 41 and 43; 59 and 61. It seems that prime
numbers (55)
in this pattern with surprising frequency, (56) with smaller numbers. As
the numbers get larger, however, the (57)
also increases dramatically. This has led to the question of whether there may (58)
be a ceiling to how many twin primes can be discovered.
With a new technique for identifying smaller than average gaps between primes,
researchers believe they are closer to solving this riddle. They hope that this will enable
them not only to identify the frequency and location of an indefinite number of twin
primes, but may also shed light on another (59)

, the Riemann Hypothesis, which
concerns an infinite sum of numbers known as the Zeta function, and (60) there is
currently a tantalizing bait of one million dollars.

V. READING COMPREHENSION (10 PTS): Read the texts below and choose the
best answer to each question.
Passage A
Nearsightedness, or myopia, results when the eye becomes too long from front to back.
Ordinarily, light passes through the corneal lens and focuses images on the rear portion of

the eye, known as the retina. The myopic eye is so long that the images focus in front of
the retina, making objects at a distance blurry. In the farsighted or hyperopic eye, the eye
is short; images focus behind the retina, causing nearby objects to blur.
Animal and human babies usually begin life slightly hyperopic. As they grow, their eyes
lengthen until all images fall perfectly on the retina, a process called emmetropization. By
the first grade, nearly all children have perfect vision. Researchers do not know what
mechanisms spur the eye to grow to a length that matches flawlessly the eye's optics.
It takes work to see at varying distances, even when vision is "perfect." Reading, for
instance, requires tiny muscles in the eye to accommodate for the short focus by making
the lens rounder. When images do not fall in focus on the retina, whether as the result of
myopia or hyperopia, corrective lenses can be recruited to do the work.
Increasingly, people in developed countries have come to rely on corrective lenses.
Sometime between starting school with perfect vision and beginning high school, up to 50
percent of kids in the United States become myopic. In places like Taiwan and Hong Kong,
where kids typically study 10 to 12 hours per day, 70 percent of older students need to
squint to see the blackboard.
61. The condition called myopia develops when
.
A. the distance between the corneal lens and the retina is increased
B. the lens of the eye can no longer focus
C. light is unable to pass through the corneal lens
D. light focuses on the retina
62. The process called emmetropization .
A. eventually produces myopia in first
graders
B. produces blurry images on the retina
C. corrects the initial condition of hyperopia most newborn babies have
D. corrects the myopia that most newborn babies have
63. The mechanisms behind the process of emmetropization.
A. are perfectly understood

B. remain a mystery
C. have been fully explained
D. have never concerned researchers
64. A corrective lens is used to ensure that .
A. images fall in focus on the retina
B. the corneal lens becomes rounder
C. distances do not vary
D. tiny muscles in the eye work
65. Indications are that myopia among high school students .
A. depends on climatic and geographical diferences
B. is on the decline in developed countries
C. results from squinting in the classroom
D. results from an increased reading load
Passage B
The Hutterites call themselves the human version of a bee colony. Members of this
Christian sect, who first settled in the United States in the 19th century, shun personal gain
and pour their eforts into a well- oiled collective enterprise.
Hutterite ideology stresses the shared fate of the group and warns against the sin of
selfishness. Anyone who withholds help from others in need, turns lazy, or otherwise
undermines community health draws stern reprimands from church elders. Failure to heed
these warnings results in forced exile.
Hutterite leaders are elected democratically and undergo a long probationary period
before acquiring full power. When a colony grows too large – which is not uncommon, as the
Hutterites have long experienced high birth rates – it sorts into two groups of equal size,
skill, and compatibility. A lottery determines which group stays and which moves to a new
location.
Such practices sound downright strange to the average suburbanite or city dweller.
Indeed, end-of- the-millennium Western societies seem to spawn far more self-absorption
than sacrifice for any “greater good.”

But the bee like tactics of Hutterite colonies highlight an evolved human capacity for
thinking in groups and advancing group interests, even at the expense of personal strivings,
asserts David Sloan Wilson, an evolutionary biologist at the State University of New York at
Binghamton.
“Groups can be functional units in their own right, and individuals sometimes behave
more like organs than like organism,” Wilson contends. “As a result, altruism is a common
feature of both human and biological nature.”
66. Hutterites are characterized by their .
A. pride
B. greed
C. selflessness
D. individualism
67. A Hutterite who displays laziness and ignores warnings to reform
.
A. is made to leave the group
B. turns selfish
C. reprimands church elders
D. shares the fate of the group
68. Which of the following does NOT apply to Hutterite leaders?
A. They have to elect deputies.
B. They have to prove themselves worthy.
C. They are chosen by the group.
D. They do not automatically assume full power.
69. What accounts for the division of many Hutterite colonies?
A. The skills of their members become unequal.
B. The members are unable to live together peacefully.
C. Too many immigrants join the colony.
D. New births within the colonies swell their population.
70. Wilson maintains that Hutterite practices .

A. mirror the average contemporary Western society.
B. reflect how strong an efect altruism can have on our actions.
C. prove that personal striving is an overwhelming force.
D. have a high capacity for self-absorption.
Passage C
It is well known that in many countries around the world people become ill and die from
an inadequate food supply. A lesser known but equally troubling problem, however, is
referred to as “hidden hunger,” which does not cause feelings of hunger in the stomach
but instead causes damage to the immune system, birth defects, and slower brain activity
due to a lack of vitamin and mineral nutrients.
According to a recent report from the United Nations, “hidden hunger” is having an
alarming efect on developing countries, even those where people have enough to eat. An
insufficient amount of iron in the diet can lower the intelligence quotient (IQ) of children by
five to seven points and an iodine deficiency cuts it by 13 more points. As a result, the
collective brainpower of entire nations is diminished as the number of children with mental
incapacities grows. Iron deficiency in adults afects productivity. It is estimated that the
Gross Domestic Product in the most afected countries has been lowered by 2 percent. An
Indian study showed that when iron was added to the diets of tea leaf pickers, their
productivity increased by 20 percent.
The report encourages governments to enrich common foods with nutrients during
processing. Even if people are instructed to take a vitamin pill daily, many will not comply.
Adding nutrients to everyday foods such as soy sauce, salt, and cooking oil is the most
efficient way to reach the majority of the population. In the United States, cases of two
serious birth defects dropped by about 20 percent after the government began adding folic
acid, a nutrient found in nuts, to flour. The tragedy of “hidden hunger” is that it can be
easily solved. Enriching foods with nutrients is a simple process that costs only a few cents
per person per year.
71. What is “hidden hunger”? It is
.
A. feeling hunger pains

B. not getting enough to eat
C. a damaged immune system
D. not getting enough nutrients
72. According to the passage, what lowers productivity?
A. slower brain activity
B. iron deficiency in adults
C. damage to the immune system
D. folic acid deficiency in children
73. What does the United Nations recommend?
A. adding iron to tea
B. adding nutrients to food
C. encouraging people to take vitamin pills
D. encouraging people to use more everyday foods like salt


74. What was the result of adding folic acid to a common food?


A. It increased productivity.
B. It lowered rates of birth defects.
C. It increased the consumption of flour.
D. It solved the problem of hidden hunger.
75. In paragraph 3, what reason does the author give for calling “hidden hunger” a tragedy?
A. It can be avoided.
B. It afects so many people.
C. So many people aren’t aware of it.
D. It afects only developing countries.
Passage D
Based on their study of ancient bones, a group of evolutionary scientists is ofering a
new explanation for how humans evolved as creatures with large brains. These scientists

studied the chemical composition of the bones of early modern humans, who lived in
Europe about 20,000 to 28,000 years ago, and of Neanderthals, who lived in the same
area from 28,000 to 130,000 years ago. Among other things, they analyzed the levels of
carbon and nitrogen isotopes found in these bones. The isotopes are thought to be the
chemical signature of a diet rich in fish and seafood. Their findings suggest that while
Neanderthals were mainly meat-eaters, early modern humans derived up to half of their
dietary protein from fish.
Fish contains a plentiful supply of omega fatty acids, which are crucial to brain
development. Two of these fatty acids that seafood contains in high levels docosahexaenic acid (DHA) and arachidonic acid (AA) - make up 60 per cent of the brain’s
structural material. The former is vital for the development of neuron membranes, the
latter for the construction of blood vessels in the brain. These chemicals, however, are
scarce in other foods, even in meat. Thus, the researchers who conducted this study argue
that the early modern humans’ diet provided them with an evolutionary edge over the
smaller-brained Neanderthals who for a while coexisted with them but then died out. It
provided them with excess energy and nutrients that could be directed towards brain
growth.
76. What does the author say about arachidonic acid?
A. It is plentiful in both fish and meat.
B. It makes up 60% of the brain’s structural material.
C. It is necessary for the development of neuron membranes.
D. It helps to build blood vessels in the brain.
77. According to this passage, a major diference between Neanderthals and early modern
humans was that .
A. Neanderthals ate more fish
B. Neanderthals died out later
C. early modern humans ate more fish
D. early modern humans had a poorer diet
78. What does the word “edge” near the end of the second paragraph refer to?
A. advantage
B. speed

C. weapon
D. food
79. This research explores the link between .
A. evolution and science.
B. meat and fish.
C. diet and lifestyle.
D. nutrition and brain development.
80. What did the researchers conclude about a diet rich in fish and seafood?
A. It is better than a diet containing a lot of fatty acids.
B. It led to the evolution of bigger brains.
C. It can add dangerous chemicals to the body.
D. It does not provide as many nutrients as a diet rich in meat.
B. WRITTEN TEST
I. CLOZE TEST (20 PTS): Read the texts below and complete each space with
ONE
suitable word.
Passage A
One of the fastest growing areas of business training nowadays is intercultural
training. I recently attended a seminar of this type and, although (1)
of it were fairly
interesting, in general I found it was not practical (2)
to be really useful in a day-to-day
sense. I have always believed that experience is the best teacher. In fact, I think that
perhaps the most enjoyable way to study (3) diversity is to observe what, when and how
other nations eat.
On my last visit to the United States I spent a weekend with a family I know. (4)
many other American families they always keep their fridge (5)
stocked so that any
member of the family can help (6)
to food if and when they feel hungry. Only

once during my visit (7) the whole family sit down together to eat a cooked meal, and my


hostess explained that this was a special (8)
in my honour as normally they were (9)
too busy at weekends with social or sporting events to eat together. In my view,
experiences like these tell us more about the role of family life and attitudes to time in
America than any (10) could do.


Passage B
Health experts have warned that the currently soaring obesity levels in European
children may
(11)
create health problems of epidemic proportions within the next three (12)
.
Over the past ten years, obesity in six-year olds has doubled while the number of obese
fifteen-year olds has trebled. If present trends continue, by 2030 between 60 and 70 per
cent of Europeans will be (13)
and 40 to 50 per cent will be obese. The (14) rise in weight-related diabetes, high
blood pressure, heart disease and some forms of cancer will place intolerable strains on
health services unless steps are (15) to address the problem.
The explosion in child obesity can be put (16)
to the increasingly inactive
lifestyles of modern children. Many parents, worried lest their children should come to
harm from traffic or strangers, discourage them from playing outdoors and instead (17)
up ever more opportunities for sedentary entertainment in the home. (18) should the
influence of the food industry be underestimated; (19)
spends one thousand times more
on advertising fast foods and convenience foods in Europe and America than the total

budget for promoting health in the same (20) regions.

Childhood self-esteem can overwhelm academic disadvantage or social (11) in
determining future earning power, according to major new research.
There is now clear evidence that the (12)
of people who had higher selfesteem at age ten (13) those of their peers whose academic performance was better at
the same age. Bright children often have higher self-esteem, as do some from more
affluent (14)
. But the study compared children from similar families and still found that
those who were psychologically well-balanced at ten were now (15) their peers.
The research also found, surprisingly, that it is not unusual for children to have high
academic achievement and low self-esteem, leading to significant later underperformance
in the job market. A spokesman for the British Association for Counselling said:” (16)
for children doesn't come only from crude parental hostility at home; it can just be (17)
or the constant feeling that they're making you tired. Children pick that up. Nor is it only
(18)
children who sufer. All too often you can ask affluent parents who the important
people in their child's life are - teachers, friends and so on - and they haven't a clue.”
Bearing out the findings of this research, many (19)
successful entrepreneurs
were (20)

academically when they were at school but had the advantage of supportive families.


III. ERROR CORRECTION: (10PTS) The following passage contains 10 errors.
Identify and correct them.

Family history is one of the Britain's fastest growing passions. Genealogy used
to be considered the preserve of bearded boffins or snobbish eccentrics, but
now thousand of people who would scorn the idea of ploughing through
academic tomes of historic information were eagerly delving into official
5 archives and public records in an efort to hunt down their ancestors. Some
are motivated by curiosity and the desire to piece together a family tree;
some hope to add excitement to their lives by digging up a colourful or
illustrious forebear. As a hobby, it's slow and time-consuming; some
enthusiasts have spent years poring over records of births, marriages and
10 deaths in search for an elusive ancestor. However, the advent of the Internet
has made things much easy and may partly explain the explosion of interest in
tracing one's root. A host of online databases allow you to look up a specific
surname quickly and instead of visiting your local public record office to
examine the official files, it is now probably possible to carry out much of your
15 research online. Even so, the results may not be whom you hoped for. A friend
of mine spent two years trying in vain to trace her family back to a famous
eighteenth century novelist; what
she came up instead is a forefather of the same name who had been the local
hangman!
