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 questions.

Tạm dịch: Họ có thể phản ứng sinh lý với một từ nhất định (“ngân hàng”) không phải vì họ đã cướp tiền, nhưng vì gần đây họ đã bị séc lủng. Trong cả hai trường hợp, máy sẽ ghi lại một “lời nói dối”. Sai lầm ngược lại cũng phổ biến. Một số người nói dối đã thực hành để có thể nói dối mà không nao núng, và những người khác học cách phản ứng với máy bằng cách căng cơ hoặc nghĩ về trải nghiệm thú vị trong các câu hỏi trung lập.
