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

B) people suddenly decide to become sailors just for fun

during their voyages. These problems mostly appear in oceans. They sometimes have to sail through

C) sailors need merely experience and knowledge of bad weather

unexpectedly bad weather, or have to fix their equipment by themselves. Because they are in the

D) something on the ship always breaks down unexpectedly

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

E) problems arise only during a long-distance voyage

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.

B) found out a compelling fact about North African climate by simulating the past climatic conditions of the last 23,000 years

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

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

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

E) monitored other continents' precipitation rates in order to conduct a meticulous study

It is implied in the passage that air pollution ----.

A recently released UNICEF report titled "Clear the Air A) requires long-term measures taken merely by the governments of South Asian countries

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

B) is at tolerable rates according to the strict standards of World Health Organization

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

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

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. 61. 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

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

According to the research by Edinburgh University, birds have begun to reach their summer breeding grounds on average about one day earlier per degree

B) the timing of the arrival to the breeding ground is of vital importance to their survival

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

C) long-distance migrating birds have advantage over the short-distance migrating birds

study looks at hundreds of species across five continents. Reaching their summer breeding grounds

D) the adaptation of various migrating birds to the changing conditions varies significantly

at the wrong time - even by a few days - may cause birds to miss out on maximum availability of vital

E) the changing temperatures might serve to the interest of most migrant birds to a great extent

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

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 D) when the birds in question opt for the exact migration season E) in what way the migrant birds have tendency to shift their habits in time

E) deals only with the ways one species reacts to the possible environmental chance

One can understand from the passage that ----.

The Department of Justice has issued official A) both the government and manufacturers address the gun use vigorously

guidelines for the manufacture of smart guns weapons that have technology to allow only the owners

B) guns can be rendered safer, however, the related technology is yet to be developed

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

C) President Obama desires to set the guidelines since he wants to do a final good deed

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

D) gun deaths can be reduced by using technology to prevent unauthorized people from using guns

initiative is undoubtedly with good intention, institutions like The National Rifle Association – which had previously boycotted Smith & Wesson’s pledge to

E) producing guns is a fruitful sector for manufacturers, and the new guidelines will enhance this

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 ----.

67.

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

B) the tropics are hosting most of the tree population of the world

trees left on Earth. Although it’s more than the previous estimate of 400 billion trees worldwide, it’s trillions less

C) previously estimated number of tree remains the same

than there used to be. A researcher team used tree density information from forests around the world along

D) the only aim at mapping tree population precisely is to understand the effects of the climate change

with satellite imagery and super-computer technology to map tree populations worldwide at the squarekilometer level. The results were much higher than

E) The findings of mapping tree populations are quite surprising

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, ----.
