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 questions:

A little more than a hundred years ago, a number of European scholars began to record stories being told in peasant cottages and compile them into the first great collection of European folk tales. Written evidence exists to prove that the folk tales they recorded existed long before then thought. Collections of sermons from the 12th to the 15th century show that medieval preachers knew of some of the same stories as those recorded by the 19th century folklorists. The collections of folk tales made in the late 19th and early 20th centuries provide a rare opportunity to make contact with the illiterate masses who have disappeared into the pass without leaving a trace. To reject folk tales as historical evidence because they cannot be dated and situation with precision centuries. But to attempt to penetrate that world is to face a daunting set of obstacles, the greatest of which is the impossibility of listening in on the story tellers. No matter how accurate they may be the versions of the tales recorded in writing cannot convey the effects that the storytellers must have used to bring the stories to life: the dramatic pauses, the sly glances, the use of gestures to set scenes, and the use of sounds punctuate action. All of those devices shaped the meaning of the tales, and all of them elude the historian. He cannot be sure that the limp and lifeless text he holds between the covers of a book provides an accurate account of the performance that took place in earlier times.

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 questions:

In 1988, for the first time in British history a National Curriculum was introduced. The National Curriculum tells pupils which subjects they have to study, what they must learn and when they have to take assessment tests. Between the ages of 14 and 16, pupils study for their GCSE ( General Certificate of Secondary Education ) exams. Pupil must take English language, Math and Science for GCSE, as well as a half GCSE in a foreign language and Technology. In addition, they must also be taught Physical Education, Religious Education and Sex Education, although they do not take exams in these subjects. At the age of 16, pupils can leave school. If pupils stay on, they usually, take A (Advanced) levels, AS ( Advanced Supplementary ) level or GNVQs ( Greater national Vocational Qualifications ). It is quite common to combine, for example, 2 A levels with 1 AS level, or 1 A level with 1 GNVQ. Pupils talking A levels study traditional subjects, such as Frech, Physics or History. To go to university, pupils usually need 2 or 3 A levels. AS levels are the same standard as A levels, but only half of the content: AS level German pupils take the A-level Gerrman language exam, but do not take the A-level German Literature exam. GNVQs are vocational qualifications. Pupils usually take on GNVQ in subjects such as Business, Leisure and Tourism, Manufacturing, and Art and Design. One GVNQ (at advanced level) is equal to two A levels.
