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:

It's called 42 - the name taken from the answer to the meaning of life, from the science fiction series The Hitchhiker's Guide to the Galaxy. 42 was founded by French technology billionaire Xavier Niel, whose backing means there are no tuition fees and accommodation is free. Mr Niel and his co-founders come from the world of technology and start-ups, and they are trying to do to education what Facebook did to communication and Airbnb to accommodation. Students at 42 are given a choice of projects that they might be set in a job as a software engineer - perhaps to design a website or a computer game. They complete a project using resources freely available on the Internet and by seeking help from their fellow students, who work alongside them in a large open-plan room full of computers. Another student will then be randomly assigned to mark their work. The founders claim this method of learning makes up for shortcomings in the traditional education system, which they say encourages students to be passive recipients of knowledge. "Peer-to-peer learning develops students with the confidence to search for solutions by themselves, often in quite creative and ingenious ways." Like in computer games, the students are asked to design and they go up a level by completing a project. They graduate when they reach level 21, which usually takes three to five years. And at the end, there is a certificate but no formal degree. Recent graduates are now working at companies including IBM, Amazon, and Tesla, as well as starting their own firms. "The feedback we have had from employers is that our graduates are more apt to go off and find out information for themselves, rather than asking their supervisors what to do next," says Brittany Bir, chief operating officer of 42 in California and a graduate of its sister school in Paris. Ms Bir says 42's graduates will be better able to work with others and discuss and defend their ideas - an important skill in the “real world” of work. "This is particularly important in computer programming, where individuals are notorious for lacking certain human skills." she says. But could 42's model of teacherless learning work in mainstream universities? Brittany Bir admits 42's methods do not suit all students. "It suits individuals who are very disciplined and self-motivated, and who are not scared by having the freedom to work at their own pace." she says.

Question 50: It can be inferred from the passage that___.         

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.

Question 50: Pupils normally study for their GCSE between the ages of________
