INSTRUCTIONS1 This paper is divided into four sections-A- ReadingB- Writing C-Grammar D-Text-books and Long Reading Text(novel) All the sections are compulsory2Separate instructions are given with each section and questionwherever necessary Read these instructions very carefully and follow them faithfully3 Donrsquot exceed the prescribed word limit while answering the questions

READING- SECTION A

Q1 Read the following passage carefully and answer the questions that follow

1 Reading comprehension (RC) is the most peculiar section in almost all scholastic entrance and employment tests The skills in RC make a lot of difference to onersquos chances of good gradesselection

2 Most students find it difficult to tackle topics that are diverse from the field they are in or they are comfortable with So one needs to develop a taste for even the most obscure and boring topic on this planet For success in RC in one should be able to understand And even with an average speed one can succeed if one implements the strategies

3 Broadly speaking RC passages can be classified in a few categories Fact based RC is the simplest form of RC These types of passages havea lot of information in the form of names numbers etc in this type of passages one should read very fast Donrsquot try to memorize any facts Just mark what author is talking about in each paragraph

4 Inference based RCis the toughest form of RC Here the passage is fairly tough to understand This includes passages on topics like Religion Spirituality Philosophy etc Most of the students will be comfortable attempting these passages The way to master them is to read them again and again

5 Topic based RC includes passageson any particular topic like economics astrology medical sciences etc Generally what makes these passages difficult is usage of technical terms For success in this type of passages we need to have a fair understanding of the definition of the term if it is defined in the passage But donrsquot worry about technical terms if they are not defined in the passage Assume them to be non- existent and proceed Key principle in these passages is that donrsquot go to the next line unless the previous line is clear

6 Reading question first and then passage is the strategy followed by a few students They just look at the questions and not options The objective is that after seeing the questions when you read the passage then you read only that part carefully where the answer is given The flaw with this is that you will not be able to remember all the questions Besides this this strategy fails when there are questions that require understanding of the passage Therefore thebest way to attempt a RC is to understand the passage very well first and then to answer the questions

Q(a)Careful reading of a passage is essential for

i answering difficult questionsii saving time and effortiii proper understanding iv selective identification of relevant parts

(b)For answering a question on RC one shouldi memorise the facts ii mark what the author is talking about in that para iii mark the essential details in para iv remember the names and numbers etc(c) for success in RC one shouldi be able to understand ii read very fast iii read between the lines iv none of the above(d) Toughest form of RC isi inference based ii understanding based iii analytical based iv topic based (e) the flaw with strategy of reading questions first and then answer isi you will remember all the questions ii you will remember all the answer iii you will not remember all the questions iv none of the above(f) the passage stress uponi understanding all the terms used in the text ii a fair understanding of the definition of the technical terms used in the textiii inference based topics are easiest iv reading questions first and then text is good method of RC(B)Answer the following questions

(a) Why do most students find Reading Comprehension difficult 1(b) Why is the topicbased RC tough 1(c) What are inference based RC about and should they be attempted 1(d) What is the flaw in the usual strategy followed by the students

1

(C) Find the words in the passage which mean the same as the following 2

i different( para 2)ii accept as true (para5)


1 One industry that remains unaffected by any depression in trade is the beauty industry The women ndash world continue to spend money on their faces and bodies even when there is a great slump in other areas of trade The number of advertisements proclaiming the miracles performed by the various beauty aids goes to support the fact that today with all the talk about emancipation equality of sexes and feminism women are still observed with their physical beauty as they were in times of Cleopatra

2 America leads the figures literally and metaphorically Many parts of Europe by virtue of being affected by political and economic instability leave precious little for women to beautify themselves May be all that women in Europe can then do is to watch and hope for the best But the rich and upper middle class women everywhere in the world block a substantial amount of their income on beautifying themselves Why is it so

3 The richer the man gets the more obsessed he becomes with high powered cars and electronic gadgets and bank balances On the contrary the women especially the urban upper middle class women find their bodies and faces worthy of investing a major part of their income

4 Women these days are much freer than they were in the last century Not only are they free to take part in social and professional functions of a society as an equal to man but also to look attractive in any given situation The beauty industry is shrewd enough to exploit this trend and women in every walk of life have something to buy from the range of products that the beauty industry offers The British matron today is thing of the past

5 As a result of the number of beauty parlours that have sprung up in every street corner ofthe metropolises and the exercises the health motors and the skin foods that they offer you can hardly run into an old woman these days One could say old ladies are fast becoming an extinct species White hair wrinkles bent backs and hollow cheeks are features of bygone era Cosmetic surgery has slowly eradicated these unwanted phenomena If

children of posterity want to look at an old woman they might have to run to an art gallery and find a medieval painting

Q 2(a) On the basis of your reading the above passage make notes on it using recognizable abbreviations wherever necessary Use a format you consider suitable Supply an appropriate title

5 Q2(b) Make a summary of the above passage in about 80 words 3

SECTION B - WRITING SKILLS
