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.

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

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.

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, ----.

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

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

E) shaping the environments of trees is detrimental to animal and plant diversity

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

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

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

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

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

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

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

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