Read the following passage and choose the best answer (A, B, C, D): The term "dyslexia” is used to describe a number of problems associated with reading, writing or spelling. Short-term memory, mathematics, concentration, personal organization and sequencing may also be affected. We do not know exactly what causes dyslexia, but we do know that it tends to run in the family. We also know that more boys suffer from dyslexia than girls and that dyslexia is more common in urban areas than in rural. One of the most common signs of dyslexia is “reversals”. People with this kind of problem often confuse letters like “b” and "a" when reading and writing or they sometimes read and write words like "tip" and "won" as “pit” and “now”. Other common characteristics are lack of punctuation, misspelling, mixed-up sentence structure and poor grammatical construction. People are born with dyslexia, but it is only when they begin to learn to write that it becomes a noticeable problem. For children with dyslexia, going to school can be a traumatic experience. Poor achievement can make them feel frustrated and insecure. They are reluctant to go to school and sometimes even skip school together, Cheating, stealing and experimenting with drugs can also occur when children regard themselves as failures. It is a common misconception that dyslexic people are of inferior intelligence. Yet Albert Einstein, Leonardo da Vinci, Thomas Edison and Hans Christian Andersen were apparently all dyslexic. There is no total cure for dyslexia; however, the effects of dyslexia can be lessened with the guidance of skilled specialists and a lot of determination.

Read the following passage and choose the best answer (A, B, C, D):
During the nineteenth century, women in the United States organized and participated in a large number of reform movements, including movements to reorganize the prison system, improve education, ban the sale of alcohol, and, most importantly, free the slaves. Some women saw similarities in the social status of women and slaves. Women like Elizabeth Cady Stanton and Lucy Stone were feminists and abolitionists who supported the rights of both women and blacks. A number of male abolitionists, including William Lloyd Garrison and Wendell Philips, also supported the rights of women to speak and participate equally with men in antislavery activities. Probably more than any other movement, abolitionism offered women a previously denied entry into politics. They became involved primarily in 20 order to better their living conditions and the conditions of others. When the Civil War ended in 1865, the Fourteenth and Fifteenth Amendments to the Constitution adopted in 1868 and 25 1870 granted citizenship and suffrage to blacks but not to women. Discouraged but resolved, feminists influenced more and more women to demand the right to vote. In 1869, the Wyoming Territory had yielded 30to demands by feminists, but eastern states resisted more stubbornly than before. A women's suffrage bill had been presented to every Congress since 1878 but it continually failed to pass until 1920, 35 when the Nineteenth Amendment granted women the right to vote.

Read the following passage and choose the best answer (A, B, C, D):
Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extrateưestrial life forms might be like. What sorts of planets are most likely to develop life? Most scientists agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble Earth’s. Water is an important solvent involved in many biological processes. Biogeochemical cycles are the continuous movement and transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’s climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important. The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and bum out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problem. First of all, planets in their habitable zones will be so close to the star that they will be “tidally locked” – that is one side of the planet will always face the star in perpetual daylight with the other side in the perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem. Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the orbits must be a good distance from one another. Interestingly, the amount of space needed is roughly the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two. Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas giants, such as Saturn and Jupiter,.in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth.

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions:
    Who talks more - men or women? Most people believe that women talk more. However, linguist Deborah Tannen, who has the studied the communication style of men and women, says that this is a stereotype. According to Tannen, women are more verbal - talk more - in private situations, where they use conversation as the “glue’ to hold relationships together. But, she says, men talk more in public situations, where they use conversation to exchange information and gain status. Tannen points out that we can see these difference even in children. Little girls often play with one ‘best friend’ and their play includes a lot of conversation. Little boys often play games in groups, their play usually involves more doing than talking. In school, girls are often better at verbal skills, while boys are often better at mathematics.
    A recent study at Emory University helps to shed light on the roots of this difference. Researchers studied conversation between children aged 3-6 and their parents. They found evidence that parents talk very differently to their sons than they do to their daughters. The startling conclusion was that parents use more language with their girls. Specifically, when parents talk with their daughters, they use more descriptive language and more details. There is also far more talk about emotions, especially with daughters than with sons.

The Finer Points of Fair Trade
Throughout the year, we buy foods and beverages from a variety of sources. However, few of us take the time to consider the lives of the people who make these things. In many cases, these goods are produced by poor workers who have trouble surviving on their salaries. A social movement called “Fair Trade” is trying to change this by ensuring that workers are paid decent wages for their efforts. The Fair Trade movement aims to create a membership between customers and producers that is based on respect and fairness. Consumers hope that by supporting fair trade goods they are empowering workers in developing countries to live better lives. Consumers also benefit because they receive high-quality products and have peace of mind that these workers aren’t mistreated. Fair Trade also benefits the environment, as Fair Trade goods are produced with minimal pesticides and pollutants. The first Fair Trade mark was introduced in 1988 by a Dutch group called Solidaridad, which focused on labeling fair trade coffee imported into Holland from Mexico. Shortly after, other groups in North America and Europe followed their lead. These groups started to seek Fair Trade benefits for workers producing wine, honey, bananas, flowers, and several other goods. Then, in 1997, the Fairtrade Labeling Organization International (FLO) was established to unite all of these independent groups into one organization and set unified standards worldwide. In 2002, the FLO launched the FAIRTRADE Certificate Mark, which became an international symbol that labeled goods met the environmental, economic, and social requirements set by FAIRTRADE International (FLO). If consumers spot this mark on goods, they are assured that the workers producing them are receiving a suitable payment for their services. Major corporations are also getting involving in the Fair Trade movement, deluding Starbucks. The multi-national coffee retailer now purchases over 93 percent of its coffee from ethical sources. Furthermore, it has pledged to increase that number to 100 percent by 2025. If you are willing to join Starbucks and millions of other consumers around the globe, keep your eyes out for the FAIRTRADE mark next time you go food shopping.

It’s in Your Genes
Every human being has about 25,000 genes. Your genes are part of your DNA. They give your body instructions on how to develop. For example, if your genes tell your body to build long, thin fingers, then you will have long, thin fingers. Your genes come from your parents, and they decide everything about you. They decide your hair colour, your eye colour, your height, and so on. Genes are still a bit of a mystery to scientists, but they are learning new things about them all the time. One issue that people often debate is this: Do our genes influence our personalities? These days, most people agree that the answer to this question is yes. Recent studies have shown that genes especially influence our self-control and our sense of purpose. Your sense of purpose is your desire to have goals in your life. If a person really wants to accomplish something and do well in life, he or she has a sense of purpose. A person who does not care about goals has no sense of purpose. Although scientists agree that our genes influence our personalities, there is another question. How much do they influence us? Can we control ourselves, or do our genes control us? People everywhere are still debating this issue. So far, we don’t really have an answer. Genes also affect your health. If a gene has a problem, it is called a mutated gene. Some mutated genes can cause diseases. That is why if a person has a certain health problem, his or her child is more likely to have that same problem. The child also has the mutated gene. As scientists and doctors learn more about genes, they are also developing a new kind of medicine: gene therapy. Therapy is help for a mental or a physical problem. Gene therapy means fixing or replacing mutated genes. Scientists are still experimenting on gene therapy. It is possible that in the future, gene therapy will help doctors prevent and cure diseases that are caused by mutated genes.
