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 following questions

Simply being bilingual doesn’t qualify someone to interpret. Interpreting is not only a mechanical process of converting one sentence in language A into the same sentence in languageb. Rather, its a complex art in which thoughts and idioms that have no obvious counterparts from tongue to tongue _ or words that have several meanings must be quickly transformed in such a way that the message is clearly and accurately expressed to the listener.

 At one international conference, an American speaker said, “You cant make a silk purse out of a sows ear”, which meant nothing to the Spanish audience. The interpretation was, “A monkey in a silk dress is still a monkey” _ an idiom the Spanish understood and that expressed the same idea.

 There are 2 kinds of interpreters, simultaneous and consecutive. The former, sitting in a separated booth, usually at a large multilingual conference, speaks to listeners wearing headphones, interpreting what a foreign language speaker says _ actually a sentence behind. Consecutive interpreters are the ones most international negotiations use. They are employed for smaller meetings without sound booths and headphones. Consecutive interpretation also requires two-person teams. A foreign speaker says his piece while the interpreter, using a special shorthand, takes notes and during a pause, tells the client what was said.
Question:The phrase “the former“ refers to…

A. simultaneous interpreters

B. the conference

C. consecutive interpreters

D. the booth

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 following question from 44 to 50.

The rules of etiquette in American restaurants depend upon a number of factors the physical location of the restaurant, e.g., rural or urban; the type of restaurant, e.g., informal or formal; and certain standards that are more universal. In other words, some standards 5 of etiquette vary significantly while other standards apply almost anywhere. Learning the proper etiquette in a particular type of restaurant in a particular area may sometimes require instruction, but more commonly it simply requires sensitivity and experience. For example, while it is acceptable to read a magazine in a coffee shop, it is 10 inappropriate to do the same in a more luxurious setting. And, if you are eating in a very rustic setting it may be fine to tuck your napkin into your shirt, but if you are in a sophisticated urban restaurant this behavior would demonstrate a lack of manners. It is safe to say, however, that in virtually every restaurant it is unacceptable 15 to indiscriminately throw your food on the floor. The conclusion we can most likely draw from the above is that while the types and locations of restaurants determine etiquette appropriate to them, some rules apply to all restaurants.

What topic is this passage primarily concerned?

A. instruction in proper etiquette

B. rules of etiquette

C. variable and universal standards of etiquette

D. the importance of good manners
