MCQ-> Read the passage carefully and choose the best answer to each question out of the four alternatives.Bertrand Russell in The Conquest of Happiness has said that the sole reason of unhappiness finding refuge in the heart of man is the unhindered growth of “self- centred passions”. These passions are more often materialistic. And in the pursuit of materialistic passions, man becomes alienated from the society. Failure in his pursuit often leads him to discontentment and dejection and he finds himself a misfit in this world. In the modern world, none is unaffected by stress. The stress to outdo the other in this mad rat race of consumerism often leads to depression.Even children are not spared from this. They are supposed to fare better than their classmates in examinations and other co-curricular activities. So man, right from childhood, has to face the brunt of being born in this fast changing society. A section of the youth, unable to cope with the expectations of their loved ones, either end their lives or experiment with drugs, for seeking temporary mental relaxation provided by the initial intake, encourages people to indulge in them more often. The body then becomes totally dependent on drugs and cannot survive without the daily dose. With regular intake the amount required to produce the effect also increases. This physical and mental dependence on drugs is called drug addiction. Drug addiction is a psychiatric, psychological and social problem. While persons of all ages and at all places are open to drug use the most susceptible among them are the youth. It has attained the proportions of almost an epidemic among the youth. It is mostly introduced to an unsuspecting person by his friends and is usually observed that once addicted to drugs, they initiate others to drugs. Some youngsters take to drugs because they are poked fun as if they do not use drugs. And some take drugs just to seek company or break boredom. In addition to these, other factors that lead to drug addiction are — lack of parental care and supervision, lack of moral and religious education, media and pop culture, broken homes, hatred for any authority, etc. Seeking refuge in drugs relieves tensions, eases depressions and removes inhibitions, although the period of ecstasy is apparently short-lived. Which of the following statements is true ?

MCQ-> Read the passage given below and answer the questions that follow it:Does having a mood disorder make you more creative? That’s the most frequent question I hear about the relationship. But because we cannot control the instance of a mood disorder (that is, we can’t turn it on and off, and measure that person’s creativity under both conditions), the question should really be: Do individuals with a mood disorder exhibit greater creativity than those without? Studies that attempt to answer this question by comparing the creativity of individuals with a mood disorder against those without, have been well, mixed.Studies that ask participants to complete surveys of creative personality, behavior or accomplishment, or to complete divergent thinking measures (where they are asked to generate lots of ideas) often find that individuals with mood disorders do not differ from those without. However, studies using “creative occupation” as an indicator of creativity (based on the assumption that those employed in these occupations are relatively more creative than others) have found that people with bipolar disorders are overrepresented in these occupations. These studies do not measure the creativity of participants directly, rather they use external records (such as censuses and medical registries) to tally the number of people with a history of mood disorders (compared with those without) who report being employed in a creative occupation at some time. These studies incorporate an enormous number of people and provide solid evidence that people who have sought treatment for mood disorders are engaged in creative occupations to a greater extent than those who have not. But can creative occupations serve as a proxy for creative ability?The creative occupations considered in these studies are overwhelmingly in the arts, which frequently provide greater autonomy and less rigid structure than the average nine-to-five job. This makes these jobs more conducive to the success of individuals who struggle with performance consistency as the result of a mood disorder. The American psychiatrist Arnold Ludwig has suggested that the level of emotional expressiveness required to be successful in various occupations creates an occupational drift and demonstrated that the pattern of expressive occupations being associated with a greater incidence of psychopathology is a self-repeating pattern. For example, professions in the creative arts are associated with greater psychopathology than professions in the sciences whereas, within creative arts professions, architects exhibit a lower lifetime prevalence rate of psychopathology than visual artists and, within the visual arts, abstract artists exhibit lower rates of psychopathology than expressive artists. Therefore, it is possible that many people who suffer from mood disorders gravitate towards these types of professions, regardless of creative ability or inclination.Go through the following:1.Mood disorders do not lead to creativity 2.The flexibility of creative occupations makes them more appealing to people with mood disorder 3.Mood swings in creative professions is less prevalent than in non-creative professionsWhich of the following would undermine the passage’s main argument?....

MCQ-> The English alphabet is divided into five groups. Each group starts with the vowel and the consonants immediately following that vowel and the consonants immediately following that vowel are included in that group. Thus, the letters A, B, C, D will be in the first group, the letters E, F, G, H will be in the second group and so on. The value of the first group is fixed as 10, the second group as 20 and so on. The value of the last group is fixed as 50. In a group, the value of each letter will be the value of that group. To calculate the value of a word, you should give the same value of each of the letters as the value of the group to which a particular letter belongs and then add all the letters of the word: If all the letters in the word belong to one group only, then the value of that word will be equal to the product of the number of letters in the word and the value of the group to which the letters belong. However, if the letters of the words belong to different groups, then first write the value of all the letters. The value of the word would be equal to the sum of the value of the first letter and double the sum of the values of the remaining letters.For Example : The value of word ‘CAB’ will be equal to 10 + 10 + 10 = 30, because all the three letters (the first letter and the remaining two) belong to the first group and so the value of each letter is 10. The value of letter BUT = $$10 + 2 \times 40 + 2 \times 50 = 190$$ because the value of first letter B is 10, the value of T = 2 $$\times$$ 40 (T belongs to the fourth group) and the value of U = 2 $$\times$$ 50 (U belongs to the fifth group). Now calculate the value of each word given in questions 161 to 165 :AGE
