Sailing seems to be nice to sailors but it is full of

dangers, boredom and problems for those who do it as

life-long profession. Sailors face a number of problems

during their voyages. These problems mostly appear in

oceans. They sometimes have to sail through

unexpectedly bad weather, or have to fix their

equipment by themselves. Because they are in the

middle of the ocean and the nearest help is often

thousands of miles away. They mostly seem to be

content with their profession, and generally it is

believed that they think so because they are used to it.

Their job may seem attractive to those who like sailing

and being alone, yet, it is of course very difficult for

ordinary people.

Every year, winds over the Sahara Desert sweep up

huge plumes of mineral dust, transporting hundreds of

teragrams across North Africa and over the Atlantic

Ocean. Such dust can be blown for thousands of

kilometers and settle in areas as far away as Florida

and the Bahamas. The Sahara has been known as the

leading source of windblown dust to the Earth's

atmosphere. However, Professor David McGee and

his team from Yale University have reported that the

African plume was far less dusty 5,000 years ago,

containing merely half the amount of dust that is

transported today. To reach accurate findings, the

researchers have reconstructed the African dust plume

over the last 23,000 years and observed a dramatic

reduction in dust. McGee state that this weakened

plume may have allowed more sunlight to reach the

ocean, increasing its temperature by 0.15 degrees

Celsius which is a slight but significant spike that likely

triggered precipitation over North Africa, where climate

at the time used to be interestingly far more temperate

and hospitable than it is today. This link between

reduction in dust and expansion of intense rain into the

Sahara could present crucial understanding of not only

past but also future climates.

56. It is clearly stated in the passage that ----.

A) massive dust plumes blown from Florida and

the Bahamas can reach far away locations

B) the accumulation of dust in the Sahara Desert

reached to an unprecedented rate in the past

C) dust plumes are more common in North Africa

and the Atlantic Ocean than in Florida and the

Bahamas

D) the Sahara Desert is considered as the

second source of mineral dust nowadays

E) the African plume has turned out to have

much less amount of dust thousand years

ago

57. One can understand from the passage that

the researchers have ----.

A) compared mineral dust particles from present

with the ones from 5,000 years ago

B) found out a compelling fact about North

African climate by simulating the past climatic

conditions of the last 23,000 years

C) ridiculed the substantial rise in sea

temperatures and its effects on the world's

climatic changes

D) discovered a dramatic decrease in sea

temperatures to be the main cause of dust

formation and drought in North Africa

E) monitored other continents' precipitation rates

in order to conduct a meticulous study

58. What could be the best title for the passage?

A) Huge Reduction in African Dust Plume

B) Profound Analysis into Climate Zones

C) Dust Plume Effects on Sea Temperatures

D) Wind Patterns of the Sahara Desert

E) Temperate Climate of North Africa

A recently released UNICEF report titled "Clear the Air

for Children” states that some 300 million children are

exposed to heavily toxic air, while two billion live in

areas where pollution exceeds minimum air quality

guidelines set by the World Health Organization. South

Asia has the largest number of children living in such

areas, around 620 million, followed by Africa and then

East Asia and Pacific region. According to this report,

among these children around 600,000 under the age of

five die globally due to air pollution. Besides being a

major factor contributing in the deaths of these

children, air pollution also threatens the future of

millions more every day. Pollutants don't only harm

children's developing lungs but they can actually cross

the blood-brain barrier and permanently damage their

developing brains and, thus, their futures. While the air

is poisoned by vehicle emissions, fossil fuels, dust,

burning waste and other airborne pollutants, indoor air

pollution, typically caused by burning coal and wood

for cooking and heating also impair children's health.

The UNICEF report urged all governments worldwide

to adapt measures such as cutting back on fossil fuel

combustion as well as investing in energy efficiency

and renewable energy sources.

59. According to the UNICEF report, ----.

A) almost 620 million children die each year

because of being subjected to extremely toxic

air

B) vehicle emissions, fossil fuels and other toxic

gasses might restrain air pollution worldwide

C) household air pollution cannot be ignored as it

endangers mortality rates in children

D) air pollutants cause temporary but severe

deterioration of children's brain cells while

damaging their lungs

E) few children around the world are at risk and

live in minimum air quality

60. It is implied in the passage that air pollution

----.

A) requires long-term measures taken merely by

the governments of South Asian countries

B) is at tolerable rates according to the strict

standards of World Health Organization

C) is supposed to be regarded as more life

threatening in Africa, the East Asia and

Pacific Region than in the other regions

D) claims not only children's lives but also their

overall wellbeing and future quality of life

E) is triggered by numerous contributors among

which the most detrimental is toxic outdoor air

61. One of the strategies to prevent mortality in

children is to ----.

A) switch to alternative energy sources that are

environmentally-friendly

B) restructure residential areas particularly in

South Asia, East Asia and Pacific region

C) implement educational programmes

supervised by the World Health Organization

D) encourage fossil fuel consumption to offset

the effects of air pollution

E) elevate the quality of air and minimize the

toxic effects of burning coal by means of

employing indoor filtering units

According to the research by Edinburgh University,

birds have begun to reach their summer breeding

grounds on average about one day earlier per degree

of increasing global temperatures. It is likely to benefit

scientists in terms of predicting how different species

may respond to future environmental change, and the

study looks at hundreds of species across five

continents. Reaching their summer breeding grounds

at the wrong time - even by a few days - may cause

birds to miss out on maximum availability of vital

resources such as food and nesting places. Late arrival

to breeding grounds may, in turn, affect the timing of

offspring hatching and their chances of survival.

Besides, long-distance migrants, which are shown to

be less responsive to rising temperatures, may suffer

most as other birds gain advantage by arriving at

breeding grounds ahead of them. Concisely, the study

examines how various species, which take flight in

response to cues such as changing seasonal

temperatures and food availability, have altered their

behaviour over time and with increasing temperatures.

62. According to the text, the study regarding the

birds ----.

A) reveals their breeding, feeding, and nesting

habits in the course of migration between

continents

B) shows the profound influence which the

unstable global temperatures have on the

migrating birds

C) presents the exact reasons why they migrate

across the specific locations in five continents

D) holds clues pertaining to the habits of bird

species in their summer breeding grounds

E) deals only with the ways one species reacts

to the possible environmental chance

63. It can be inferred from the text that ----.

A) birds are able to reach the breeding grounds

in a single day despite the increasing

temperatures

B) the timing of the arrival to the breeding

ground is of vital importance to their survival

C) long-distance migrating birds have advantage

over the short-distance migrating birds

D) the adaptation of various migrating birds to

the changing conditions varies significantly

E) the changing temperatures might serve to the

interest of most migrant birds to a great extent

64. The text is mainly about ----.

A) how the behaviours of migrant birds are

affected at certain times of the year

B) what the specific motives behind the

migration of the birds are

C) what the study offers to the would-be

researchers in the field

The Department of Justice has issued official

guidelines for the manufacture of smart guns -

weapons that have technology to allow only the owners

to use them. Ordered by President Obama, the

guidelines aim to “shape the future of gun safety

technology”. In order to prevent thousands of deaths

from misuse of guns, guns could be equipped with

technology, such as fingerprint scanners, enabling only

the owner to use them. However, although Obama’s

initiative is undoubtedly with good intention, institutions

like The National Rifle Association – which had

previously boycotted Smith & Wesson’s pledge to

explore smart gun technology – have sneered that

Obama’s aim is to claim a win before his days in office

end. Likewise, the Congress had also refused to fight

the gun deaths among the nation. The technology is

available. A shotgun that blocked firing by anyone

without the shooter’s radio-frequency identity ring was

already developed in 2000. Yet, what is not available is

emancipation from the politics and threats of the gun

lobby who, apparently, do not want to lose their share

of the market that is more lucrative without the

standards that the guidelines mean to bring.

65. According to the passage, the guidelines for

the production of smart guns ----.

A) are meant to set the standards for gun

production with aim to decrease deaths by

gun misuse

B) are rejoiced by the entire country in that they

will start a new era of gun safety technology

C) do not seem to be very promising since the

required technology is still at its infancy

D) are welcomed by the gun lobby for they bear

the potential to create new income channels

E) have been proposed upon the Congress’s call

for a way of dealing with gun-related deaths

66. One can understand from the passage that

----.

A) both the government and manufacturers

address the gun use vigorously

B) guns can be rendered safer, however, the

related technology is yet to be developed

C) President Obama desires to set the

guidelines since he wants to do a final good

deed

D) gun deaths can be reduced by using

technology to prevent unauthorized people

from using guns

E) producing guns is a fruitful sector for

manufacturers, and the new guidelines will

enhance this

67. The best title for this passage could be ----.

A) Developing gun safety technology

B) Guns production and gun lobbying

C) Guidelines for effective guns safety

D) Why not smart guns in this high-tech era?

E) Why can’t we stop deaths caused by guns?

A Yale University study suggests there are more trees

in the world than previously estimated. Billions of trees

are being cut down every year - estimated three trillion

trees left on Earth. Although it’s more than the previous

estimate of 400 billion trees worldwide, it’s trillions less

than there used to be. A researcher team used tree

density information from forests around the world along

with satellite imagery and super-computer technology

to map tree populations worldwide at the square-

kilometer level. The results were much higher than

expected. According to the research, the highest

densities of trees are found in the boreal forests in the

sub-arctic regions of Russia, Scandinavia and North

America, but the largest forest areas are in the tropics,

which are home to about 43 percent of the world's

trees population. The information on the population of

trees will help scientists to better understand the

effects of climate change, the distribution of animal and

plant species in the world and how trees shape their

environments.

68. According to the passage, besides tree

density information, ----.

A) the team used imageries and advanced

progress aiming at mapping the tree

population

B) the number of trees is decreasing worldwide

due to excessive chopping down

C) understanding the impact of climate change

depends on just strict regulations

D) boreal forests are found around the dominant

countries along with the air pollution

E) shaping the environments of trees is

detrimental to animal and plant diversity

69. It is stressed in the passage that ----.

A) the research mainly focuses on ascending the

tree population in sub-arctic regions

B) the tropics are hosting most of the tree

population of the world

C) previously estimated number of tree remains

the same

D) the only aim at mapping tree population

precisely is to understand the effects of the

climate change

E) The findings of mapping tree populations are

quite surprising

70. We can understand from the passage that

even the largest forest areas ----.

A) cover less than half of the tree population

worldwide

B) are estimated to be 400 acres before the

current study

C) consist of numerous trees beyond

expectations

D) can be measured by satellite imageries and

advanced technologies

E) cannot make up for human induced damage

71. Scientists from the University of Michigan in the

USA have found that the brain of astronauts

changes shape during spaceflight. It is the first

study to look into how the brain changes on the

journey into space. Researchers looked at MRIs

of 26 astronauts who spent time in space.

Twelve of the astronauts spent two weeks as

Space Shuttle crew members, and 14 spent six

months on the International Space Station. ----.

Therefore, the researchers concluded that the

longer an astronaut spent in space, the bigger

the differences in size were.

A) It has long been known that the bigger the brain

of a species is the more intelligent they are

B) All of them experienced increases and

decreases in the size of different parts of the

brain

C) The astronauts also fixed the problems, which

occurred in the space stations

D) These findings will help NASA to conduct more

research

E) Space voyages had a profound effect on the

psychology of the astronauts’ families

72. The number of people who die in traffic

accidents is so high that measures need to be

taken urgently. Actually, deaths can be

minimized by several very simple measures. ----.

Though this is a very simple safety measure,

few people care about it.

A) For instance, wearing the seatbelts can save

thousands of lives

B) Cars should be serviced at least once a year to

avoid major expenditure

C) Statistics indicate all drivers wear their seatbelts

in short distance travel in Sweden

D) People with serious eye defects are not given

driving licences in Norway

E) Speed limit is the fastest speed at which you

can travel safely

73. Experts questioned 85 professional female

models over the age of 18. They discovered that

81% of them were underweight. Many of the

models led a very unhealthy lifestyle to stay

underweight so that they could get work from

their agencies. ----. They kept their

“commercially slim and elegant look” in this

way. This is mainly because the models said

their agency told them they would not get jobs

unless they lost more weight.

A) In fact, the study was published in the

‘International Journal of Eating Disorders’

B) Therefore, it is made up of five jury members

C) In contrast, these foreign models had been

suffering from diseases

D) However, the court decided it was wrong to put

them under pressure

E) In doing so, they skipped meals, stopped eating

for days, and used diet pills

74. The truth is that spraying around any private

information is risky. You might think that’s

overblown. As long as you have nothing to hide,

you have nothing to worry about. It’s not that

simple. Even if you’ve done nothing illegal or

immoral, faced with a database of every

photograph and comment you’ve ever shared

privately, friendships and business deals could

dissolve the world over. And there are plenty of

vulnerabilities. Although there are safeguards,

data can in theory be hacked, stolen or altered

at many points along the way. The system itself

is a bit complex. ---- . Whenever you upload text

or pictures, they are ferried to these farms by

cables.

A) Such an everyday occurrence will send information on unexpected routes

B) The material displayed on the web is stored, often in central server farms

C) You can attach it to an email in your Gmail app and send it to your friends

D) Online banking has also been a matter of debate in terms of security

E) Old cameras are the best way of keeping private memories as they are

75. Developing a brand new rocket, aerospace

Rocket Lab has finally transported a finished

vehicle to New Zealand launch pad where it will

take first flight. ---- Compared to other major

missiles like the Falcon 9 or the Atlas V, it is

pretty small and light because it was designed

specifically to launch small satellites. That’s a

relatively light lift contrasted with the others.

But Rocket Lab isn’t interested in competing

with major players like SpaceX or the United

Launch Alliance. The company wants to

capitalize solely on what is called the small

satellite revolution, a trend of making space

probes as tiny as possible.

A) Typically, manufacturers spend years and millions of dollars developing a satellite that’s roughly the size of a bus.

B) But technology has advanced in recent years, so companies have come up with ways to miniaturize their satellites.

C) In contrast, the government did not support the project

D) The rocket, called the Electron, has been tested on the ground over the last year but has never been flown to space before.

E) Since they are so compact, multiple probes can be launched on a single rocket

77. (I) The odor of a flower can range from sweet like

vanilla to fresh. (II) It doesn’t smell good to please

humans but rather to attract “a specific pollinator”

that is, an insect or bird that will carry pollen from

one flower to another for reproduction.

(III) Different pollinators like different smells.

78. (I) We are running out of space in which to discard

our garbage, and our current methods of disposing

of it are endangering the environment.

(II) Recycling, one solution to this problem, is the

process of collecting used materials and

manufacturing them into new products instead of

throwing them away. (III) Recycling is being done

worldwide, for example, in Germany it is a usual

practice. (IV) In this way the trash in overcrowded

landfills can be reduced. (V) Also materials that are

used to make new products can be reduced and

natural resources can be saved as well.


79. (I) Earthquakes are a kind of catastrophes

occurring all over the world. (II) At any time you

may hear news about them with a lot of energy and

power or with small tremors that are seldom felt.

(III) Besides they are not just seen on land; huge

waves in the ocean can be caused by a kind of

underwater earthquake. (IV) In deep waters it is

sometimes hard to see enormous waves due to

earthquakes but when they reach the coast they

grow into large walls of water. (V) Most big cities

including Istanbul are not ready for a sudden

earthquake, though.
