Direction for questions 76 to 80 – Read the passage and answer the questions that follow     

Sign has become a scientific hot button. Only in the past 20 years have specialists in language study realized that signed languages are unique - a speech of the hand. They offer a new way to probe how the brain generates and understands language, and throw new light on an old scientific controversy: whether language, complete with grammar is something that we are born with, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of one rebel teacher at Gallaudet University in Washington, D.C., the world's only liberal arts university for deaf people.

When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something odd: among themselves, students signed differently from his classroom teacher. Stokoe had been taught a sort of code gestures, each movement of the hands representing a word in English. At the time, American Sign Language (ASL) was thought to be no more than a form of pidgin English but Stokoe believed the "hand talk" his students used looked richer. He wondered: Might deaf people actually have a genuine language? And could that language be unlike any other on Earth? It was in 1955, when even deaf people dismissed their signing as "substandard". Stokoe's idea was an academic heresy. It is 37 years later. Stokoe - now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture - is having lunch at a cafe near the Gallaudet campus and explaining how he started a revolution. For decades educators fought his idea that signed languages are natural languages like English, French and Japanese. They assumed language must be based on speech, the modulation of sound. But sign language is based on the movement of hands, the modulation of space. "What I said," Stokoe explains, "is that language is not mouth stuff- it is brain stuff."

76.       The study of sign language is thought to be

A)        an approach to simplifying the grammatical structure of a language

B)        an attempt to clarify misunderstanding about the origin of language

C)        a challenge to traditional views on the nature of language

D)        a new way to took at the learning of language

77.       The present growing interest in sign language was stimulated by

A)        a leading specialist in the study of liberal arts

B)        an English teacher in a university for the deaf

C)        some senior experts in American Sign Language

D)        a famous Scholar in the study of the human brain

78.       According to Stokoe, sign language is

A)        an international language               B)        a substandard language      

C) an artificial language                              D) a genuine language

79.       Most educators objected to Stokoe's idea because they thought

A)        a language should be easy to use and understand

B)        sign language was too artificial to be widely accepted

C)        a language could only exist in the form of speech sounds

D)        sign language was not extensively used even by deaf people

80.       Stokoe's argument is based on his belief that

A)        language is a product of the brain

B)        language is a system of meaningful codes

C)        sign language is derived from natural language

D)        sign language is as efficient as any other language

Direction for questions 81 to 85 – Read the passage and answer the questions that follow     

A is for always getting to work on time. B is for being extremely busy. C is for the conscientious way you do your job. You may be all these things at the office and more. But when it comes to getting ahead, experts say: the ABCs of business should include a P, for politics, as in office politics.

Dale Carnegie suggested as much more than 50 years ago hard work alone doesn't ensure career advance in men. You have to be able to sell yourself and your ideas, both publicly and behind the scenes. Yet, despite the obvious rewards of engaging in office politics - a better job, a raise, praise- many people are still unable or unwilling - to "play the game."

"People assume that office politics involves some manipulative behavior." says Deborah Comer, an assistant professor of management at Hofstra University. "But politics which is derived from the word 'polite' can mean lobbying and forming associations. It can mean being kind and helpful, or even trying, to please your superior, and then expecting something in return."

In fact, today, experts define office politics as proper behavior used to pursue one's own self-interest in the workplace. In many cases, this involves some form of socializing within the office environment - not just in large companies, but in small workplaces as well.

"The first thing is people are usually judged on their ability to perform well on a consistent basis," says Neil P. Lewis, a management psychologist. "But if two or three candidates are up for a promotion, each of whom has reasonably similar ability, a manager is going to promote the person he or she likes best. It's simple human nature."

Yet, psychologists say, many employees and employers have trouble with the concept of politics in the office. Some people say, have an idealistic vision of work and what it takes to succeed. Still others associate politics with flattery, fearful that, if they speak up for themselves, they may appear to be flattering their boss for favors.

Experts suggest altering this negative picture by recognizing the need for some self-promotion.

Direction for questions 86 to 90 – Read the passage and answer the questions that follow     

It came as something of a surprise when Diana, Princess of Wales, made a trip to Angola in 1997, to support the Red Cross's campaign for a total ban on all anti-personnel landmines. Within hours of arriving in Angola, television screens around the world were filled with images of her comforting victims injured in explosions caused by landmines. "I knew the statistics," she said. "But putting a face to those figures brought the reality home to me; like when I met Sandra, a 13- year-old girl who had lost her leg, and people like her."

The Princess concluded with a simple message: "We must stop landmines". And she used every opportunity during her visit to repeat this message.

But, back in London, her views were not shared by some members of the British government, which refused to support a ban on these weapons. Angry politicians launched an attack on the Princess in the press. They described her as "very ill-informed" and a "loose cannon.

The Princess responded by brushing aside the Criticisms: "This is a distraction we do not need. All I'm trying to do is help."

Opposition parties, the media and the public immediately voiced their support for the Princess. To make matters worse for the government, it soon emerged that the Princess's trip had been approved by the Foreign Office, and that she was in fact very well-informed about both the situation in Angola and the British government's policy regarding landmines. The result was a severe embarrassment for the government to try and limit the damage, the Foreign Secretary, Malcolm Rifkidnd, claimed that the Princess's views on landmines were not very different from government policy, and that it was "working towards" a worldwide ban. The Defense Secretary, Michael Portillo, claimed the matter was "a misinterpretation or misunderstanding." -

For the Princess, the trip to this war-torn country was an excellent opportunity to use her popularity to show the world how much destruction and suffering landmines can cause. She said that the experience had also given her the chance to get closer to people and their problems.
