Read the following article and select the best answer. Article: Psychological noise refers to forces within a communicator that interfere with the ability to express or understand a message exactly. For instance, an outdoor person might overstate the size and number of the fish he caught in order to convince himself and others of his talents. In the same way, a student might become so upset upon learning that she failed a test that she would be unable ( Perhaps " unwilling" is a better word) to understand clearly where she went wrong. Indeed, psychological noise is a very important communication problem. But the linear model, despite its advantages, suggests that communication flows in one direction, from sender to receiver. Although some types of messages ( printed and broadcast messages, for example) do flow in a one-way, linear manner, most types of communication, especially the interpersonal variety are two-way exchanges. To put it differently, the linear view ignores the fact that receivers react to massages by sending other messages of their own. Consider, for example, the meaning of a friend's yawn as you describe your romantic problems. Or imagine the hot face you may see as you tell one of your dirty jokes to a new friend. Nonverbal behaviors like these show that most face-to-face communication is a two-way affair. The discernible response of a receiver to sender's massage is called feedback. Not all feedback is nonverbal, of course. Sometimes it is oral, as when you ask an instructor questions about an upcoming test or volunteer your opinion of a friend's new haircut. In other cases it is written, as when you answer the questions on a midterm exam or respond to a letter from a faraway friend. Question: Which of following considered to be a psychological noise? - A person likes to tell others his achievements - A person goes fishing every day instead of going to work - A person often overestimates his ability - A person talks without noticing others' reaction
A person often overestimates his ability

Read the following article and select the best answer. Article: Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The ridge structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident. When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained. Question: It is _ for a criminal to deny his crime when finger-prints are used to identify him. - worth trying - successful - useful - useless
useless

Read the following article and select the best answer. Article: Odland remembers like it was yesterday working in an expensive French restaurant in Denver. The ice cream he was serving fell onto the white dress of a rich and important woman. Thirty years have passed, but Odland can not get the memory out of his mind, nor the woman's kind reaction . She was shocked, regained calmness and, in a kind voice, told the young Odland. "It is OK. It wasn't your fault." When she left the restaurant, she also left the future Fortune 500 CEO with a life lesson: You can tell a lot about a person by the way he or she treats the waiter. Odland isn't the only CEO to have made this discovery. Instead, it seems to be one of those few laws of the land that every CEO learns on the way up. It's hard to get a dozen CEO's to agree about anything, but most agree with the Waiter Rule. They say how others treat the CEO says nothing. But how others treat the waiter is like a window into the soul. Watch out for anyone who pulls out the power card to say something like, "I could buy this place and fire you," or "I know the owner and I could have you fired." Those who say such things have shown more about their character than about their wealth and power. The CEO who came up with it, or at least first wrote it down, is Raytheon CEO Bill Swanson. He wrote a best-selling book called Swanson's Unwritten Rules of Management. "A person who is nice to you but rude to the waiter, or to others, is not a nice person," Swanson says. "I will never offer a job to the person who is sweet to the boss but turns _ o someone cleaning the tables." Question: From the text we can learn that _ . - one should be nicer to important people - CEOs often show their power before others - one should respect others no matter who they are - CEOs often have meals in expensive restaurants
one should respect others no matter who they are

Read the following article and select the best answer. Article: Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University's School of Life and Health Sciences. The findings suggest there may be some scientific basis to the "5 second rule" --- the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the 5 second rule, until now it was unclear whether it actually helped. The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor flooring types (carpet, cement floor etc.) to toast, pasta, a biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: Time is a significant factor in the transfer of bacteria from a floor surface to a piece of food; and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said: "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time." The Aston team also carried out a survey of the number of people who employ the 5 second rule. The survey showed that: 87% of people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those who would eat or have eaten food dropped on the floor are women. 81% of the women who would eat food from the floor would follow the 5 second rule. Professor Hilton added, "Our study showed that a surprisingly large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the 5 second rule." Question: The passage is developed probably by _ . - time - space - contrast - example
