Read the following passage and mark the letter A, B, C or D on you answer sheet to indicate the correct answer to each of the questions. Although the "lie detectors" are being used by governments, police departments, and businesses that all want guaranteed ways of detecting the truth, the results are not always accurate. Lie detectors are properly called emotion detectors, for their aim is to measure bodily changes that contradict what a person says. The polygraph machine records changes in heart rate, breathing, blood pressure, and the electrical activity of the skin (galvanic skin response, or GSR). In the first part of the polygraph test, you are electronically connected to the machine and asked a few neutral questions ("What is your name?", "Where do you live?"). Your physical reactions serve as the standard (baseline) for evaluating what comes next. Then you are asked a few critical questions among the neutral ones ("When did you rob the bank!). The assumption is that if you are guilty, your body will reveal the truth, even if you try to deny it. Your heart rate, respiration, and GSR will change abruptly as you respond to the incriminating questions. That is the theory: but psychologists have found that lie detectors are simply not reliable. Since most physical changes are the same across all emotions, machines cannot tell whether you are feeling guilty, angry, nervous, thrilled, or revved up from an exciting day. Innocent people may be tense and nervous about the whole procedure. They may react physiologically to a certain word (“bank”) not because they robbed it, but because they recently bounced a check. In either case the machine will record a "lie". The reverse mistake is also common. Some practiced liars can lie without flinching, and others learn to beat the machine by tensing muscles or thinking about an exciting experience during neutral questionsThe word "assumption" in paragraph 1 could best be replaced with _________.

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 36 to 42.Do you feel like your teenager is spending most of the day glued to a phone screen? You're not too far off. A new survey from the Pew Research Center reveals the surprising ways that technology intersects with teen friendships – and the results show that 57 percent of teens have made at least one new friend online. Even more surprisingly, only 20 percent of those digital friends ever meet in person. While teens do connect with their friends face-to-face outside of school, they spend 55 percent of their day texting with friends, and only 25 percent of teens are spending actual time with their friends on a daily basis (outside of school hallways). These new forms of communication are key in maintaining friendships day-to-day – 27 percent of teens instant message their friends every day, 23 percent connect through social media every day, and 7 percent even video chat daily. Text messaging remains the main form of communication – almost half of survey respondents say it's their chosen method of communication with their closest friend. While girls are more likely to text with their close friends, boys are meeting new friends (and maintaining friendships) in the gaming world – 89 percent play with friends they know, and 54 percent play with online-only friends. Whether they're close with their teammates or not, online gamers say that playing makes them feel "more connected" to friends they know, or garners they've never met. When making new friends, social media has also become a major part of the teenage identity – 62 percent of teens are quick to share their social media usernames when connecting with a new friend (although 80 percent still consider their phone number the best method of contact). Despite the negative consequences-21 percent of teenage users feel worse about their lives because of posts they see on social media – teens also have found support and connection through various platforms. In fact, 68 percent of teens received support during a challenging time in their lives via social media platforms. Just as technology has become a gateway for new friendships, or a channel to stay connected with current friends, it can also make a friendship breakup more public. The study reveals that girls are more likely to block or unfriend former allies, and 68 percent of all teenage users report experiencing "drama among their friends on social media."

When making new friends, social media has also become a major part of the teenage identity – 62 percent of teens are quick to share their social media usernames when connecting with a new friend (although 80 percent still consider their phone number the best method of contact). Despite the negative consequences-21 percent of teenage users feel worse about their lives because of posts they see on social media – teens also have found support and connection through various platforms. In fact, 68 percent of teens received support during a challenging time in their lives via social media platforms. Just as technology has become a gateway for new friendships, or a channel to stay connected with current friends, it can also make a friendship breakup more public. The study reveals that girls are more likely to block or unfriend former allies, and 68 percent of all teenage users report experiencing "drama among their friends on social media."

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 31 to 35.Stars have been significant features in the design of many United States coins and their number has varied from one to forty-eight stars. Most of the coins issued from about 1799 to the early years of the twentieth century bore thirteen stars representing the thirteen original colonies. Curiously enough, the first American silver coins, issued in 1794, had fifteen stars because by that time Vermont and Kentucky have joined the Union. At that time it was apparently the intention of mint officials to add a star for each new state. Following the admission of Tennessee in 1796, for example, some varieties of half dimes, dimes, and half dollars were produced with sixteen stars. As more states were admitted to the Union, however, it quickly became apparent that this scheme would not prove practical and the coins from 1798 were issued with only thirteen Stars - one for each of the original colonies. Due to an error at the mint, one variety of the 1828 half-cent was issued with only twelve stars. There is also a variety of the large cent with only 12 stars, but this is the result of a die break and is not a true error.Which of the following is NOT mentioned as the denomination of an American coin?
