The aviation industry, especially the commercial aviation sector, is constantly striving to improve both the way it works and its customer satisfaction. It has begun using artificial intelligence. Though AI in the aviation industry is still in the nascent stage, some progress has been made already as certain leading carriers invest in AI. To make a long story short, AI can redefine how the aviation industry goes about its work. In 2017, American Airlines conducted an app development competition with the goal of having an app developed for making baggage screening easier for passengers. The competition, named HackWars, was themed upon artificial intelligence, drones and augmented and virtual reality. The winner, known as “Team Avatar,” developed an app that would not only allow passengers determine their baggage size before arriving at the airport, but also prepay any potential baggage-related expenses. United Airlines is using Amazon’s Alexa to have certain common customer queries answered. In September 2017, United announced a collaboration with Alexa. The feature is known as the United skill. To get started, all passengers need to do is to  add the United skill to their Alexa app and then start asking questions. Alexa answers common queries correctly, such as the status of a flight by number, check-in requests and availability of Wi-Fi on a flight. The reviews so far have been mixed, which points to the fact that there is a learning curve, and it is still a long way to go before AI can fully handle customer assistance. Tracking progress is an enormous challenge that airlines will face. The first thing they need to do is to develop analytics that will help them develop and process accurate data. However, that in itself is a challenge. What kind of analytics will help? For example, customer satisfaction is going to be one of the most important factors in success. What kind of analytics will determine that airlines have been improving on customer satisfaction parameters? AI needs huge investments, and probably the biggest risk in this is smaller, especially budget airlines are going to miss out on reaping the benefits of AI fully. Does that mean that the performance of the smaller carriers will be impacted? That might not be the case, because we might be moving toward more acquisitions and mergers. Bigger airlines will have a massive appetite for acquiring smaller airlines with an eye on the market. It is not all gloom and doom though, because smaller airlines like Southwest have already shown some initiatives toward embracing AI. It is surprising that a sector as important as aviation has woken up to AI so late. As AI in aviation picks up its pace, there could probably be a few mergers, acquisitions or even closure of small airlines which will not be able to afford the investments. Now, AI seems the best option to take aviation to the next level.

Commentary from researchers in the College of Pharmacy at The University of Texas at Austin in the journal Science provide new findings in alcohol use disorder (AUD) research The article, “Compelled to drink: Why some cannot stop,” considers recent findings by researchers Siciliano et al. that discovered individual differences in the activity of neurons in a frontal cortex to brain stem circuit that predicts the later escalation of alcohol drinking to compulsive intake in a mouse model. “These researchers not only defined a new brain circuit involved in compulsive drinking, but showed individual differences at the level of electrical activity in the neurons that comprise this circuit,” Nixon said. “The individual differences in electrical activity predicted which mice would go on to drink compulsively after a binge-like drinking episode despite drinking the same amount of alcohol during that episode.” The research group previously found that this circuit is important for responses to aversive events, and they have now asked why aversive outcomes don’t deter everyone from drinking alcohol. These new findings point to a neurological explanation for why only some mice continue to drink alcohol even when it comes with negative consequences. “They found these differences in circuit activity before mice developed compulsive drinking behavior,” Mangieri said. “In other words, some mice had a biological predisposition that made them susceptible to developing alcohol drinking behaviors that are similar to humans with AUD.” The researchers said the work has important implications. It has potential as a biomarker of propensity to develop severe AUD based on electrical activity. Also, the discovery of this circuit’s role in compulsive drinking suggests that there may be novel pharmacological targets that could be identified and developed for the treatment of AUDs
3. According to paragraph 2, what is the nature of the compulsive behaviours of people with AUD?

Read the following passage and choose the best answer (A, B, C, D):
Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat. The term “latent heat” refers to the energy that has to be used to convert liquid water to water vapor. We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime they will dry faster than in winter, when temperatures are colder. The energy used in both cases to change liquid water to water vapor is supplied by heat – supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. It is stored in water vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere. In the atmosphere, a large portion of the Sun’s incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to quantify this proportion of the Sun’s energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun’s energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large-scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere

Read the following passage and choose the best answer (A, B, C, D):
Far from being barren wastelands, deserts are biologically rich habitats with a vast  array of animals and plants that have adapted to the harsh conditions there. Some deserts are among the planet’s last remaining areas of total wilderness. Yet more than one billion people, one-sixth of the Earth’s population, actually live in desert regions.  Deserts cover more than one fifth of the Earth’s land, and they are found on every continent. A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert. Deserts are part of a wider classification of regions called “dry lands.” These areas exist under a moisture deficit, which means they can frequently lose more moisture through evaporation than they receive from annual precipitation.  And despite the common conceptions of deserts as dry and hot, there are cold deserts as well. The largest hot desert in the world, northern Africa’s Sahara, reaches temperatures of  up to 122 degrees Fahrenheit (50 degrees Celsius) during the day. But some deserts are always cold, like the Gobi desert in Asia and the desert on the continent of Antarctica. Others are mountainous. Only about 10 percent of deserts are covered by sand dunes. The driest deserts get less than half an inch (one centimeter) of precipitation each year, and that is from condensed fog not rain.  Desert animals have adapted ways to help them keep cool and use less water. Camels, for example, can go for days without food and water. Many desert animals are nocturnal, coming out only when the brutal sun has descended to hunt. Some animals, like the desert tortoise in the south-western United States, spend much of their time underground. Most desert birds are nomadic, crisscrossing the skies in search of food. Because of their very special adaptations, desert animals are extremely vulnerable to introduced predators and changes to their habitat.  Some of the world’s semi-arid regions are turning into desert at an alarming rate. This process, known as “desertification,” is not caused by drought, but usually arises from the demands of human populations that settle on the semi-arid lands to grow crops and graze animals. The pounding of the soil by the hooves of livestock may degrade the soil and encourage erosion by wind and water.

It was not until 1920 when women finally got the right to vote. This was 50 years after the male ex-slaves of the United States were gaining the right to vote. Though women had already right to vote, the stereotypes made women be restricted in their actions. Would you believe that women who were doing the same job as men were getting paid only the 60% of what man wear to paint? In fact, they were getting paid differently for doing exactly the same work. In the 1930s there was not a huge choice of workplace for women. They could still work as secretaries, nurses, teachers and social workers. These kinds of professions were considered typically female professions and were paid much less than other professions. That kind of restrictions themed unbearable for some women. They rejected to go on with this rules anymore. They changed their hair color, style appearance and started to fight against the existing stereotypes. Those women were named in history as “flappers”. The first time in history they started wearing short skirts which were something shocking to the society. They also started driving cars, drinking alcohol, which raised a huge boom. Those kinds of things were considered “Non-feminine”. Actions of flappers were accepted as radical, though they had their influence on the society finally. The heavy restrictions started disappearing every year and today we have what we have. For a very long time, women were considered inferior to men. However, the role of a woman in society has significantly changed during recent decades. Today the importance of women in the society is beyond any suspicion. In today’s world, women with their ambitions, intelligence and strength have proved that the word “inferior” has nothing in common with their gender.  
4. According to paragraph 2, which statement is NOT how the people of the past view the behaviours of “flappers”?

In the United States, presidential elections are held in years evenly divisible by four (1888, 1900, 1964, etc.). Since 1840, American presidents elected in years ending with zero have died in office, with one exception. William H. Harrison, the man who served the shortest term, died of pneumonia only several weeks after his inauguration.
Abraham Lincoln was one of four presidents who were assassinated. He was elected in 1860, and his untimely death came just five years later. James Garfield, a former Union army general from Ohio, was shot during his first year in office (1881) by a man to whom he wouldn’t give a job. While in his second term of office (1901), William McKinley, another Ohioan, attended the Pan-American Exposition in Buffalo, New York. During the reception, he was assassinated while shaking hands with some of the guests. John F. Kennedy was assassinated in 1963 in Dallas only three years after his election.
Three years after his election in 1920, Warren G, Harding died in office. Although it was never proved, many believe he was poisoned. Franklin Roosevelt was elected four times (1932, 1936, 1940 and 1944), the only man to serve so long a term. He had contracted polio in 1921 and eventually died of the illness in 1945.
Ronald Reagan, who was elected in 1980 and reelected four years later, suffered an assassination attempt but did not succumb to the assassin’s bullets. He was the first to break the long chain of unfortunate events. Will the candidate in the election of 2020 also be as lucky?

"Did you see that?" Joe said to his friend Bill. "You're a great shooter!"
Bill caught the basketball and bounced it before throwing it again. The ball flew into the net. "Bill, you never miss!" Joe said admiringly.
"Unless I'm in a real game," Bill complained. "Then I miss all the time."
Joe knew that Bill was right. Bill performed much better when he was having fun with Joe in the school yard than he did when he was playing for the school team in front of a large crowd.
"Maybe you just need to practice more," Joe suggested.
"But I practice all the time with you!" Bill objected. He shook his head. "I just can't play well when people are watching me."
"You play well when I'm watching," Joe pointed out.
"That's because I've known you since we were five years old," Bill said with a smile. "I'm just not comfortable playing when other people are around."
Joe nodded and understood, but he also had an idea.
The next day Joe and Bill met in the school yard again to practice. After a few minutes, Joe excused himself.
"Practice without me," Joe said to his friend. "I'll be back in a minute."
Joe hurried through the school building, gathering together whomever he could find - two students, a math teacher, two secretaries, and a janitor. When Joe explained why he needed them, everyone was happy to help.
Joe reminded the group to stay quiet as they all went toward the school's basketball court. As Joe had hoped, Bill was still practicing basketball. He made five baskets in a row without noticing the silent people standing behind him.
"Hey, Bill!" Joe called out finally.
Bill turned. A look of surprise came over his face.
I just wanted to show you that you could play well with people watching you," Joe said. "Now you'll have nothing to worry about for the next game!"

Read the following passage and choose the best answer (A, B, C, D):
Kids can be creatures of habit. Much like how they can watch the same movie over and over, some kids will stick to one author or genre of book that they’ve fallen in love with. But does it matter if they’re always reading the same type of book? After all, isn’t their love of reading in itself enough? Reading builds their imagination, develops their critical thinking skills, and improves their communication skills, amongst many other benefits. Well, while a love of reading of any sort is to be nurtured, when a child only reads the same author or type of book, their growth and the benefits they gain may not be as broad if they were to explore more types of books. Coaxing them to open up to reading other genres can be a big advantage for them in the long term. They will get exposed to different types of characters and lifestyles when they read a wider range of writing. For example, their favourite fantasy novels may spark their imagination, but true tales of life halfway around the world can trigger interest in traveling and foster understanding of other cultures. It helps them develop a broad perspective on the world around them. Their vocabulary will benefit, too, if they read a wide selection of books. Think of the words and the sentence structure used in a vampire book and how they will differ significantly from those in a suspense novel. They will have to sound out words, and it’ll be helpful to have a dictionary handy. With each new word encountered in the broad range of reading materials they’re consuming, their vocabulary grows. Reading a variety of books will also help your child grow their love of reading and it’ll fuel their motivation to read more and more. They once only adored one author, who has  a limited number of books written, discovering new authors or types of books expands their choice of reading material; they’ll never run out of books to add to their reading list! Consider, too, the value of specific types of books for very young readers. Ones that teach the alphabet help them learn that letters come together to form the words in books. Poetry with rhyming words will help develop a child’s phonemic awareness, which is the ability to hear, identify and manipulate individual sounds in spoken words. Folktales and nursery rhymes are beloved and cherished. Surely there are ones that bring you right back to your childhood, and they tend to be shared from one generation to the next - your child’s favourite will likely be ones they teach their children when they grow up and have kids of their own!

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions:
It is many peoples dream to become a world-famous artist. Unfortunately, it can be extremely difficult to make a living solely from selling your paintings or sculptures. But don’t worry because there are other jobs in the world of art that you can pursue. One possible career option is to become an art dealer.
An art dealer works on behalf of artists to help them sell works to museums and galleries around the world. To be successful at this profession, it requires a well-rounded skill set. For starters, it helps a lot if you love art and are knowledgeable about art history. Having business skills will also be quite useful, as it will be necessary to negotiate with buyers, and help the artists you represent market their work. If becoming an art dealer sounds appealing, there are several steps which you can follow. Although you  may have a love for a wide range of styles, you should start by choosing one category to focus on. Buyers usually prefer to deal with a specialist in a particular area than someone who is a jack of all trades. When selecting your focus, choose an area that you are passionate about instead of something that seems lucrative. Art trends come and go, so there is no use trying to predict what is hot. These trends will certainly change over the course of your career.
Once you selected an area to focus on, start to contact some museums, galleries, and other companies in the art world and send them your resume. The majority of art dealers begin their careers working as interns for these kinds of companies. Although these interns may be paid little, or in some cases nothing at all, the experience of learning how art businesses work will certainly serve you down the road.
It pays to be flexible in the beginning, as the most important thing is to get your foot in the door. Museums and galleries may offer you several positions including a sales assistant or a junior art consultant. Whichever job you accept, be sure to learn it well and give it your best. In addition to your responsibilities, make sure your start to network with others in your industry. As your knowledge and contacts begin to grow, more opportunities will be open to you.

The best quality of an art dealer to start the career may be     .
