MCQ-> Read the following passage and provide appropriate answers for the questionsThere is an essential and irreducible ‘duality’ in the normative conceptualization of an individual person. We can see the person in terms of his or her ‘agency’, recognizing and respecting his or her ability to form goals, commitments, values, etc., and we can also see the person in terms of his or her ‘well-being’. This dichotomy is lost in a model of exclusively self- interested motivation, in which a person’s agency must be entirely geared to his or her own well-being. But once that straitjacket of self-interested motivation is removed, it becomes possible to recognize the indisputable fact that the person’s agency can well be geared to considerations not covered - or at least not fully covered - by his or her own well-being. Agency may be seen as important (not just instrumentally for the pursuit of well-being, but also intrinsically), but that still leaves open the question as to how that agency is to be evaluated and appraised. Even though the use of one’s agency is a matter for oneself to judge, the need for careful assessment of aims, objective, allegiances, etc., and the conception of the good, may be important and exacting. To recognize the distinction between the ‘agency aspect’ and the ‘well-being aspect’ of a person does not require us to take the view that the person’s success as an agent must be independent, or completely separable from, his or her success in terms of well-being. A person may well feel happier and better off as a result of achieving what he or she wanted to achieve - perhaps for his or her family, or community, or class, or party, or some other cause. Also it is quite possible that a person’s well-being will go down as a result of frustration if there is some failure to achieve what he or she wanted to achieve as an agent, even though those achievements are not directly concerned with his or her well-being. There is really no sound basis for demanding that the agency aspect and the well-being aspect of a person should be independent of each other, and it is, I suppose, even possible that every change in one will affect the other as well. However, the point at issue is not the plausibility of their independence, but the sustainability and relevance of the distinction. The fact that two variables may be so related that one cannot change without the other, does not imply that they are the same variable, or that they will have the same values, or that the value of one can be obtained from the other on basis of some simple transformation. The importance of an agency achievement does not rest entirely on the enhancement of well-being that it may indirectly cause. The agency achievement and well-being achievement, both of which have some distinct importance, may be casually linked with each other, but this fact does not compromise the specific importance of either. In so far as utility - based welfare calculations concentrate only on the well- being of the person, ignoring the agency aspect, or actually fails to distinguish between the agency aspect and well-being aspect altogether, something of real importance is lost.According to the ideas in the passage, the following are not true expect:

MCQ-> Analyse the following passage and provide appropriate answers for the follow. Popper claimed, scientific beliefs are universal in character, and have to be so if they are to serve us in explanation and prediction. For the universality of a scientific belief implies that, no matter how many instances we have found positive, there will always be an indefinite number of unexamined instances which may or may not also be positive. We have no good reason for supposing that any of these unexamined instances will be positive, or will be negative, so we must refrain from drawing any conclusions. On the other hand, a single negative instance is sufficient to prove that the belief is false, for such an instance is logically incompatible with the universal truth of the belief. Provided, therefore, that the instance is accepted as negative we must conclude that the scientific belief is false. In short, we can sometimes deduce that a universal scientific belief is false but we can never induce that a universal scientific belief is true. It is sometimes argued that this 'asymmetry' between verification and falsification is not nearly as pronounced as Popper declared it to be. Thus, there is no inconsistency in holding that a universal scientific belief is false despite any number of positive instances; and there is no inconsistency either in holding that a universal scientific belief is true despite the evidence of a negative instance. For the belief that an instance is negative is itself a scientific belief and may be falsified by experimental evidence which we accept and which is inconsistent with it. When, for example, we draw a right-angled triangle on the surface of a sphere using parts of three great circles for its sides, and discover that for this triangle Pythagoras' Theorem does not hold, we may decide that this apparently negative instance is not really negative because it is not a genuine instance at all. Triangles drawn on the surfaces of spheres are not the sort of triangles which fall within the scope of Pythagoras' Theorem. Falsification, that is to say, is no more capable of yielding conclusive rejections of scientific belief than verification is of yielding conclusive acceptances of scientific beliefs. The asymmetry between falsification and verification, therefore, has less logical significance than Popper supposed. We should, though, resist this reasoning. Falsifications may not be conclusive, for the acceptances on which rejections are based are always provisional acceptances. But, nevertheless, it remains the case that, in falsification, if we accept falsifying claims then, to remain consistent, we must reject falsified claims. On the other hand, although verifications are also not conclusive, our acceptance or rejection of verifying instances has no implications concerning the acceptance or rejection of verified claims. Falsifying claims sometimes give us a good reason for rejecting a scientific belief, namely when the claims are accepted. But verifying claims, even when accepted, give us no good and appropriate reason for accepting any scientific belief, because any such reason would have to be inductive to be appropriate and there are no good inductive reasons.According to Popper, the statement "Scientific beliefs are universal in character" implies that....

MCQ-> Read the following passage carefully and answer the given questions. Certain words are given in bold to help you to locate them while answering some of the questions. King Harish loved his people and look after the affairs of the kingdom well. One day he and his minister Chandan took a stroll through the market. People were buying and selling and there were no beggars to be seen anywhere. The King was delighted to see the prosperity of his kingdom. He turned to Chandan and said, ‘I want to check firsthand how content my people are. Summon people from all walks of life to court.” The next day, ‘the king arrived at court and said, As your king I want to know if all of you are happy. Do you have enough for your needs?” The citizens looked at each other, thought and one by one came forward to say that their kitchens have enough food, their trade was going well, their wells were overflowing and the king had kept them safe. The king was pleased at this but Chandan had a frown and he whispered something to the king. The king was astonished but seeing Chandan was serious he turned to the court and made an announcement, “I am delighted you are all happy. Tomorrow I want all the happy people to gather at the gate of the royal garden. You have to enter the garden from the main gate, walk across and meet me by the gate at the rear of the garden. Each of you will be given a sack and you can pick whatever your heart desires.” The crowd was excited as no one was usually allowed access to the king’s garden which was said to be filled with all kinds of beautiful and strange plants.The next day, everyone gathered at the gate of the palace garden well before time. At the appointed time the guards opened the gates and handed out sacks. Citizens began roaming around the garden and filled their sacks with the juicy apples, pomegranates, grapes and mangoes hanging from trees. But as they walked further into the garden they saw trees laden with gold and silver fruits. They began madly filling their sacks with these precious fruits. Everyone forgot that they had enough for their needs at home and the fruits they had picked earlier were thrown on the ground forgotten and left to rot. Then with their sacks filled to the top the citizens made their way to the rear gate but they found a rushing stream blocking their path. The current was strong and as there were no boats, the only way to cross was to swim across. But how could they swim with laden sacks. All stood by the stream except one young man who simply abandoned his sack and swam across. Angry and unhappy the others refused to cross. The king was sad and said, “Yesterday all of you said you were happy but today you are distressed. ”Turning to the young man who was smiling he asked, ‘Tell me why are you not sad?” “Sire, I picked some tasty fruits for my precious daughter but when I saw no other way across, I did not think twice about leaving these behind. I am happy you let us wander around in your garden.”Choose the word which is most nearly the opposite in meaning to the word SERIOUS given in bold as used in the passage.
