The best salespeople first establish a mood of trust and rapport by means of "hypnotic pacing" statements and gestures that play back a customer"s observations, experience, or behavior. Pacing is a kind of mirror-like matching, a way of suggesting: "I am like you. We are in sync. You can trust me". The simplest form of pacing is "descriptive pacing", in which the seller formulates accurate, if banal, descriptions of the customer"s experience. "It"s been awfully hot these last few days, hasn"t it... You said you were going to graduate in June". These statements serve the purpose of establishing agreement and developing an unconscious affinity between seller and customer. In clinical hypnosis, the hypnotist might make comparable pacing statements. "You are ham today to see me for hypnosis". "You told me over the phone about a problem that concerns you". Sales agents with only average success tend to jump immediately into their memorized sales pitches or to hit the customer with a barrage of questions. Neglecting to pace the customer, the mediocre sales agent creates no common ground on which to build trust. A second type of hypnotic pacing statement is the "objection pacing" comment. A customer objects or resists, and the sales agent agrees, matching his or her remarks to the remarks of the customer. A superior insurance agent might agree that "insurance is not the best investment out there", just as a clinical hypnotist might tell a difficult subject. "You are resisting going into trance. That"s good. I encourage that". The customer, pushing against a wall, finds that the wall has disappeared. The agent, having confirmed the customer"s objection, then leads the customer to a position that negates or undermines the objection. The insurance salesperson who agreed that "insurance is not the best investment out there" went on to tell his customer, "but it does have a few uses". He then described all the benefits of life insurance. Mediocre salespeople generally respond to resistance head-on, with arguments that presumably answer the customer"s objection. This response often leads the customer to dig in his heels all the harder. The most powerful forms of pacing have more to do with how something is said than with what is said. The good salesperson has ability to pace the language and thought of any customer. With hypnotic effect, the agent matches the voice tone, rhythm, volume, and speech rate of the customer. He matches the customer"s posture, body language, and mood. He adopts the characteristic verbal language of the customer. If the customer is slightly depressed, the agent chares that feeling and acknowledges that he has been feeling "a little down" lately. Ill essence, the top sales producer becomes a sophisticated biofeedback mechanism, sharing and reflecting the customer"s reality—even to the point of breathing in and out with the customer. We are in sync is another way of saying______.

A. we are alike, particularly in our way of thinking
B. we are going to like each other
C. we don"t have the same ideas, but we respect each other"s ideas
D. we are in the same situation

Parents can easily come down with an acute case of schizophrenia from reading the contradictory reports about the state of the public schools. One sat of experts asserts that the schools are better than they have been for years. Others say that the schools are in terrible shape and are responsible for every national problem from urban poverty to the trade deficit. One group of experts looks primarily at such indicators as test scores, and they cheer what they see: all the indicators—reading scores, minimum competency test results, the Scholastic Aptitude Test scores—are up, some by substantial margins. Students are required to take more academic courses—more mathematics and science, along with greater stress on basic skills, including knowledge of computers. More than 40 state legislatures have mandated such changes. But in the eyes of another set of school reformers such changes are at best superficial and at worst counterproductive. These experts say that merely toughening requirements, without either improving the quality of instruction or, even more important, changing the way schools are organized and children are taught makes the schools worse rather than better. They challenge the nature of the test, mostly multiple choice or true or false, by which children"s progress is measured; they charge that raising the test scores by drilling pupils to come up with the right answers does not improve knowledge, understanding and the capacity to think logically and independently. In addition, these critics fear that the get-tough approach to school reform will cause more of the youngsters at the bottom to give up and drop out. This, they say, may improve national scores but drain even further the nation"s pool of educated people. The way to cut through the confusion is to understand the different yardsticks used by different observers. Compared with what schools used to be like "in the good old days", with lots of drill and uniform requirements, and the expectation that many youngsters who could not make it would drop out and find their way into unskilled jobs—by those yardsticks the schools have measurably improved in recent years. But by the yardsticks of those experts who believe that the old school was deficient in teaching the skills needed in the modern world, today"s schools have not become better. These educators believe that rigid new mandates may actually have made the schools worse. The assertion of the experts who think schools axe doing better is based on the______.

A. qualification of the teachers
B. test scores
C. reading ability of the children
D. basic skills of the children
