CAT Mock Test - 11 (November 13) - CAT MCQ

Directions: Read the following passage carefully and answer the given question.

Ask any hardcore substance addict (try this only when they are sober) how his or her very first experience was, and they will for sure tell you it was not a very pleasant one. The violent cough of the first puff, the distaste of the first sip, the bitterness of the powder, hits them first; the feel-good factor and ecstasy that ends up in an unbreakable bond comes slowly, and much later. That's why we urge you to start the new addiction programme now, whatever be the initial hiccups.
Every patient is different, from shy and submissive to bold and aggressive; some are dead scared of injections while others go in for heart surgery with a smile. But the 'argumentative' types are special and the most difficult to handle; give them a piece of advice and they would be ready with an instant counter-argument. But it is these argumentative ones who teach the old doctors a new trick or two, by asking odd and embarrassing questions, forcing us to dig up old medical journals or try surfing the Net. That's exactly what happened when this young man asked me: ''I am not overweight, neither do I have diabetes, high blood pressure or heart disease. Then why do you want me to exercise?'' The answer to that question is far from simple.
fMRI, or functional Magnetic Resonance Imaging, is a system that can track blood circulation and show the intensity of activation of a localised area of the brain during a specific activity. Reading, for example, activates the occipital cortex, speaking lights up the speech area, while decision-making switches on the frontal cortex.
In a study researchers looked into the fMRI pattern in those who do regular exercise, and found that a 'C'-shaped structure, the caudate nucleus, a part of the basal ganglia, becomes highly active. This is caused by flooding of that area by a neurotransmitter called dopamine. This area is the reward area of the brain, and such activation makes the person feel happy. They also discovered that exercise released a hormone called BDNF (Brain Derived Neurotrophic Factor) and endorphins, which resulted in such activation. While BDNF neutralised stress, endorphins took away the pain and fatigue of the exercise. But what stumped the researchers was that the pattern of activation matched the fMRI imaging pattern of a nicotine or cocaine addict. The fMRI image of a cocaine addict who is high and a health freak doing exercise had an uncanny similarity from the perspective of neurochemistry and brain imaging.
Lack of exercise is a technology problem. Today we don't even walk to our neighbour to chat; we pick up the mobile instead. And then there is the lure of sitting back at home knowing that the world of entertainment is just a click away, right in front of us, in our bedroom on LCD TV in high definition.
Some 150 minutes of exercise a week translates into 30 minutes a day for five days a week, which you can split it up into two 15 minute sessions of brisk walking. And that 15 minutes of apparent 'waste-of-time' would not only reduce your 'waist-in-time' but also reduce the chances of your developing high blood pressure, diabetes, heart disease and stroke, each by 30 per cent. A similar reduction of chance of depression and consequent improvement of self-confidence would be a bonus. For the eight-to-five creatures, who claim to be too busy, we advise them to walk or cycle to office.
The theme of World Heart Day, which fell last week on September 29, was, 'power your life' and stay heart healthy. You can do that by getting hooked on to a new addiction - 'daily exercise'. All you need is to hold on till the initial hiccough is over - and then it would be bliss. No legal restrictions, side-effects or withdrawal problems.

Q. According to the passage, which of the following revelations was rather surprising?

Directions: The passage below is followed by a question based on its content. Answer the question on the basis of what is stated or implied in the passage.

Beliefs in witchcraft in the generic sense are conspicuous in most small-scale communities where interaction is based upon personal relationships that tend to be life-long and difficult to break. In such societies belief in witches makes it possible for misfortunes to be explained in terms of disturbed social relationships; and the threat either of being accused of witchcraft or of being attacked by witches may well be a source of social control, making people more circumspect about their conduct toward others. Witches who are blamed for misfortunes, while visit near kinsmen and neighbours, are conceived of as inhuman and beyond the pale of decent society. They are, thus, convenient scapegoats who are blamed for events otherwise inexplicable in terms of the limited empirical knowledge prevailing in a society with a poorly developed technology - e.g., events such as sudden death or persistent illness or even accidents.
This explanatory function of witchcraft is widespread. So too are some of the details of the witch's believed habits and techniques, such as operating at night flying through the air on broomsticks or saucer shaped winnowing baskets.
The inherent disharmonies in the social system are cloaked under an insistence that there is harmony in the values of the society, and the surface disturbances that they cause are attributed to the wickedness of individuals. This is why the witch and sorcerer become the villains of the society's morality plays, the ones to whom the most inhuman crimes and characteristics are attributed. So numerous and so revolting are the believed practices of witches that to accuse anyone of witchcraft is a condensed way of charging him with a long list of the foulest crimes - and much the same may be said of sorcery, except that the alleged sorcerer might find some room for defence in the ambiguity as to when the use of destructive magic is legitimate and when it is to be regarded as sorcery.
Because accusations of witchcraft, if they are successful, are devastating attacks on reputation, they punctuate the micro-political processes relating to many forms of competition for some scarce status, power, resource, or personal affiliation. The believed victim of witchcraft or sorcery may also sometimes be regarded as getting his just deserts if he has, by tactless folly, incurred the wrath of dangerous, powerful persons in the community.
Because in such belief systems the transgressors of a society's ideals are depicted with dramatic disapproval, witchcraft and sorcery are usually powerful brakes upon social change. In many preliterate societies in modem times it is often those who have progressed economically and educationally who are most obsessed by fears of attack by witches and sorcerers or of accusation of employing witchcraft or sorcery. This is because they find themselves either out of line in social orders that economically at least are equalitarian or with a new-found status that lacks a niche in the traditional hierarchy.
On the other hand, belief in witchcraft may, under certain circumstances, have the effect of accelerating social change; e.g., by facilitating the rupture of close relationships that have become redundant but are difficult to break off in such a situation an accusation of witchcraft has the effect of making a public issue out of what started as a private quarrel.

Directions: Answer the question based on the following passage:

The famous gorilla experiment conducted by Harvard University when a woman dressed in a gorilla suit ambled across the floor thumping her chest, but 50 % of the audience didn't notice. The study shows we often err when it comes to concentration and perception. Humans have a limited capacity for attention which in turn means that we have a limited capacity to process information at any given point of time.
When we open our eyes, the whole image gets projected on the retina, but only selective parts of the image are sensed by the brain. This is because as the amount of information in the image was too great to be processed, the brain selectively puts its attention on the most important aspects. Scientists have found that highly prominent events may go unnoticed.
Researchers now recognize a phenomenon known as "change blindness", which means that people often fail to detect changes in their field of vision, so long that the change takes place during an eye movement or when the view is somehow interrupted. It has been discovered that our brain tries to construct a meaningful whole out of stimuli that fits in with the scenario of its interest and is capable of discarding majority of other information. This fact can be easily explained by observing a child play the game "spot the difference". On the first look the child finds the pictures to be similar. Only after careful attention, does he find the differences. The present decade has seen a lot of research into this field. The questions that the scientists are trying to answer are: What is the amount of visual input a brain can consciously and unconsciously encode?
Why do some objects come in the field of observation and not others? What happens to information that is subconsciously perceived?
Arien Mack and Irvin Rock also conducted many experiments and co-authored a book "Inattentional Blindness" in 1998. One of their experiments was very simple. They asked the subjects to observe a cross on the computer screen. The subjects were repetitively asked to judge which arm of the cross was longer. They were in a way made to concentrate on the cross. After some time, unrepentantly, another brightly coloured object was inserted in their field of vision. The researchers reported that the participants often failed to notice the unexpected object on the screen, even when it appeared in the middle of their line of vision. The study gave a conclusive proof that there exists a wide gulf between perception and attention. Some psychologists are of the view that intentional blindness may be in some way related to selective memory instead of selective perception. The cause of the 'intentional amnesia' may be organic, functional or circumstantial.
Harvard university researchers have concluded that "we consciously see far less of our world than we think we do. We might well encode much of our visual world without awareness." We believe that we generally see what is in front of us and by basically looking. But looking and seeing are two different events. It has been observed that we look without seeing during moments of intense concentration. We have all observed that our eyes may be open, the images form on the retina, but still we have limited perception. We all remember these moments of blurred visuals and they come usually when either we are in deep thoughts or involved in an interesting conversation.

Helvetius, amongst many false positions and licentious reveries, observes with much justice, that the education of man begins at his birth, and is carried on during the whole course of his life. The lowest mechanic, though he may not have distinct and accurate science, has yet such a store of geography, of natural history, of mechanics, and other parts of knowledge, that were his mind to be emptied of it, the wretched vacancy would amaze us.

Directions: The passage given below is followed by four alternative summaries. Choose the option that best captures the essence of the passage.

One principle of life drives man. This principle is physical sensibility. What produces in him this sensibility? A feeling of love for pleasure, and of hatred for pain? It is from both these feelings joined together in man and always present in his mind that is formed what one calls in him the feeling of self-love. This self-love engenders the desire for happiness; the desire for happiness that for power; and it is this latter that in turn brings forth envy, avarice, ambition and generally all the artificial passions, which, under different names, are only a disguised love of power in us and applied to the various means of obtaining it.

Directions: Shivani is a private employee and she earns a fixed salary every month. She also pays tax. The tax is always calculated after the deductions if there exists any kind of deductions. The deductions are as follows:

(i) Shivani donates 40,000 in an orphanage which has 100% exemption.

(ii) The standard deductions is one - third of the annual salary.

After allowing the deductions, the remaining income is taxed, which is so called tax before rebate. The rate of the tax on her taxable income is 20%. As she saves 35,000 rupees towards the contributory provident fund and 25,000 towards public provident fund, 20% of each can be deducted from the tax calculated before the rebate. This is the tax after rebate.

There is a surcharge to be imposed and it is imposed after the rebate and the total amount to be paid is calculated. The surcharge is 5% on the tax after the rebate which amounts to 5000 rupees.

In a game show, there are X number of multi–colour LEDs each of which can be operated by the pressing of a different button that is connected to each of the LEDs . If a multi–colour LED is initially OFF, pressing the button connected to the multi–colour LED once will make the multi–colour LED glow Green. Pressing it two times makes the multi–colour LED glow Blue. Pressing the button three times the same multi–colour LED glow Yellow. Pressing the same button four times the multi–colour LED will glow Red. While pressing it a fifth time the multi–colour LED will be switched OFF. In the same way, the cycle repeats itself or any number of buttons presses from the sixth time onwards.
The X multi–colour LEDs are all in one room and none is visible from outside this room. The buttons connected to these X multi–colour LEDs are all in a different room. Avinash, a participant in the game show, was asked to operate the buttons and try to figure out the respective button connected to each multi–colour LED. Every time he enters the room in which the multi–colour LEDs are present and checks the status of the multi–colour LEDs, it is counted as one visit.
