* 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 questions from 43 to 50. In addition to improved physical health, sport plays a primarily positive role in youth development, including improved academic achievement, higher self- esteem, fewer behavioural problems, and better psychosocial development. Many studies focus on the effects of sport on the five “C’ s” - competence, confidence, connections, character, and caring The many facets of playing sport - the discipline of training, learning teamwork, following the leadership of coaches and captains, learning to lose - provide lifelong skills for athletes. The literature on youth sport stresses the positive effects of participation in learning the important life skills of goal setting and time management combined with enjoyment; the development of a strong sense of morality; and the development of an appreciation of diversity. Studies have shown that children and youth participating in sport, when compared to peers who do not play sport, exhibit higher grades, expectations, and attainment; greater personal confidence and self-esteem; greater connections with school — that is, greater attachment and support from adults; stronger peer relationships; more academically oriented friends; greater family attachment and more frequent interactions with parents; more restraint in avoiding risky behaviour; and greater involvement in volunteer work. Sport provides opportunities for children and youth to engage in valuable and positive relationships with adults. Thus, it is a missed opportunity for children who are “gated” - or not included in sport - during early stages of childhood because they are less well behaved than other children. These children are being prevented from participating in the very thing that could help them learn to control and regulate their behaviour. Sport provides an opportunity for children to safely navigate and negotiate between right and wrong as they learn to interact with peers and adults. Research by Taliaferro et al. suggests that playing sport can even protect against suicide risk in youth. Compared to nonathletes, male athletes exhibit lower levels of hopelessness and suicidal ideation. Young males involved in multiple sports seem to gamer even more protection in this regard. Similar results were found for girls. Research on the role of exercise in adults confirms that it improves mood and alleviates many forms of depression. Bartko and Eccles found that youth who are highly involved in sport are more “psychologically resilient,” that is, better able to recover from problems. Eccles et al. found that sport participation protects young athletes against social isolation. (Adaptedfrom: Sport is a way of life, Sun Star Baguio, Jan 10, 2017) Which of the followings is NOT prevented as a result of playing sports?

* Read the following passage and mark the letter A, R, C, or D on your answer sheet to indicate the correct answer to each of the questions from 24 to 30. People have been donating blood since the early twentieth century to help accident victims and patients undergoing surgical procedures. Usually a pint of whole blood is donated, and it is then divided into platelets, white blood cells, and red blood cells. People can donate blood (for red blood cells) about once every two months. Transfusing the blood from the donor to the recipient is straightforward. It involves taking the blood from a donor’s arm vein by means of a hypodermic syringe. The blood flows down from the container by gravity. This is a slow process and may last as long as 2 hours to complete the infusion of blood into the recipient. The patient is protected from being infected during the transfusion. Only sterile containers, tubing, and needles are used, and this helps ensure that transfused or stored blood is not exposed to disease causing bacteria. Negative reactions to transfusions are not unusual. The recipient may suffer an allergic reaction or be sensitive to donor leukocytes. Some may suffer from an undetected red cell incompatibility. Unexplained reactions are also fairly common. Although they are rare, other causes of such negative reactions include contaminated blood, air bubbles in the blood, overloading of the circulatory system through administration of excess blood, or sensitivity to donor plasma or platelets. Today, hospitals and blood banks go to great lengths to screen all blood donors and their blood. All donated blood is routinely and rigorously tested for diseases, such as HIV, hepatitis B, and syphilis. When the recipient is a newborn or an infant, the blood is usually irradiated to eliminate harmful elements. Donated blood is washed, and the white blood cells and platelets removed. Storing the blood sometimes requires a freezing process. To freeze the red blood cells, a glycerol solution is added. To unfreeze the, the glycerolis removed. The ability to store blood for long periods has been a boon to human health.What does the author imply in the passage?

* 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 questions from 43 to 50. It is often the case with folktales that they develop from actual happenings but in their development lose much of their factual base; the story of Pocahontas quite possibly fits into this category of folktale. This princess of the Powhatan tribe was firmly established in the lore of early America and has been made even more famous by the Disney film based on the folktale that arose from her life. She was a real-life person, but the actual story of her life most probably different considerably from the folktale and the movie based on the folktale. Powhatan, the chief of a confederacy of tribes in Virginia, had several daughters, none of whom was actually named Pocahontas. The nickname means “playful one,” and several of Powhatan’s daughters were called Pocahontas. The daughter of Powhatan who became the subject of the folktale was named Matoaka. What has been verified about Matoaka, or Pocahontas as she has come to be known, is that she did marry an Englishman and that she did spend time in England before she died there at a young age. In the spring of 1613, a young Pocahontas was captured by the English and taken into Jamestown. There she was treated with courtesy as the daughter of chief Powhatan. While Pocahontas was at Jamestown, English gentlemen John Rolfe fell in love with her and asked her to marry. Both the governor of the Jamestown colony and Pocahontas’s father Powhatan approved the marriage as a means of securing peace between Powhatan’s tribe and the English at Jamestown. In 1616, Pocahontas accompanied her new husband to England, where she was royally received. Shortly before her planned return to Virginia in 1617, she contracted an illness and died rather suddenly. A major part of the folktale of Pocahontas that is unverified concerns her love for English Captain John Smith is the period of time before her capture by the British and her rescue of him from almost certain death. Captain John Smith was indeed at the colony of Jamestown and was acquainted with Powhatan and his daughters, he even described meeting them in 1612 journal. However, the story of his rescue by the young maiden did not appear in his writing until 1624, well after Pocahontas had aroused widespread interest in England by her marriage to an English gentlemen and her visit to England. It is the discrepancy in dates that has caused some historians to doubt the veracity of the tale. However, other historians do argue quite persuasively that this incident did truly take place. (“Preparation Course " for the TEOFL Test - Deborah Phillips - Longman) Why are some historians doubtful about the portion of the Pocahontas folktale dealing with John Smith?
