Sheldon Cooper and Barry Kripke are 2 rival scientists at a world-renowned university. They both require highly expensive laser equipment for their research project but the university could afford only one. Not wanting to take sides of either of the scientists, Dr Siebert proposed them to use their logical brains to compete in a game and the winner would be allowed to use the equipment first. The game had following rules
  1. An electric dog will be placed on the building which has ground floor as Level 0, 1st floor as Level 1 and so on. The dog will be placed on level N where N is an integer.
  2. Each of the scientists will take a turn alternatively in deciding whether the dog jumps down 1 or 3 or 4 levels
  3. Whichever scientist is able to make the dog land on level 0 will win
  4. If the dog is at level 2, the only move possible is to bring down the dog by 1 level
Both the scientist play with the intention of winning and can not skip their turn
Q. At beginning of the game, Sheldon looked at the level at which the dog was placed. He did a mental calculation and graciously offered Kripke to start the game. Kripke started the game by making the dog jump down 1 level. Which of the following 3 levels 1,3 and 4 will Sheldon surely not command the dog to jump down to ensure he wins the game?
    Correct answer is '3'. Can you explain this answer?

    Let us work from the bottom of the building to understand the winning scenarios:
    If the dog is at level 1, the command of 1 level down has to be given and thus dog will reach level 0 which will result in a win. Thus level 1 is always a winning position
    If the dog is at level 2, the person will have no other option but to bring down the dog by level 1. His opponent will start at level 1 and win the game. Thus level 2 is a losing position

    W = 
    L = Lose
    If the dog is at Level 3 or Level 4, the dog can be given command of jumping down 3 or 4 levels and thus dog will reach level 0 and the person giving the command will be the winner.

    W = Win
    L = Lose
    If the dog is at Level 5, it can be given the command to go down either 1 or 3 or 4 levels and will land on Level 4 or Level 2 or Level 1. The person would want the dog to land in such a way that the opponent gets the dog in losing position thus at this stage dog has to jump down 3 levels and land at level 2. Thus level 5 is a winning position
    If the dog is at Level 6, it can be given the command to go down either 1 or 3 or 4 levels and will land on Level 5 or Level 3 or Level 2.The person would want the dog to land in such a way that the opponent gets the dog in losing position thus at this stage dog has to jump down 4 levels and land at level 2. Thus level 6 is a winning position.
    If the dog is at Level 7, it can be given the command to go down either 1 or 3 or 4 levels and will land on Level 6 or Level 4 or Level 3. All of which is a winning position for the opponent. Therefore, whoever gets Level 7 is sure to lose

    W = Win
    L = Lose
    If the dog is in level 8, then he can be given the command to jump down 1 level leaving the opponent at Level 7 which is a losing position. Thus level 8 is winning position.
    If the dog is at Level 9, it can be given the command to go down either 1 or 3 or 4 levels and will land on Level 8 or Level 6 or Level 5.All of which are a winning position and hence level 9 is a losing position
    If the dog is at Level 10, it can be given the command to go down either 1 or 3 or 4 levels and will land on Level 9 or Level 7 or Level 6.The person would want the dog to land in such a way that the opponent gets the dog in losing position thus at this stage dog has to jump down 3 levels and land at level 7. Thus level 10 is a winning position.

    W = Win
    L = Lose
    We see that a similar condition has been discussed earlier also, hence we observe that the previous 7 observation are repeating itself
    If the player receives the dog on the level which is of form 7k or 7k+2 then the person is sure to lose the game.
    Since it is known that the players will play smartly to win, Sheldon will only give chance to Kripke if he is sure that the starting level is the losing level. Thus it is of the form 7k or 7k+2.
    Therefore he'll receive the dog at the level which is of form 7k-1 or 7k+1
    If the dog is at the level of form 7k+1, Sheldon will have to give the command to the dog to come 1 level down in order to ensure that Kripke stays on losing the level.
    If the dog is at the level of form 7k-1, Sheldon will have to give the command to the dog to come 4 levels down in order to ensure that Kripke get the dog on level 7k-5 or 7k' +2 (where k=k'+1) which is a losing level.
    In any scenario, Sheldon will not command the dog to jump down 3 levels.

    Sheldon Cooper and Barry Kripke are 2 rival scientists at a world-reno...
    Explanation:

    Analysis of the Game:
    - The key to winning the game is to ensure that the dog lands on level 0.
    - The scientists need to strategize their moves to lead the dog to level 0 while preventing their opponent from achieving the same.

    Initial Placement:
    - The dog is initially placed at level N.

    Sheldon's Strategy:
    - Sheldon observed the initial level of the dog and made a mental calculation to determine the winning strategy.
    - He graciously offered Kripke to start the game, indicating that he has a winning strategy in mind.

    Kripke's Move:
    - Kripke started the game by making the dog jump down 1 level.
    - This move by Kripke gives Sheldon an advantage to strategize his moves to lead the dog to level 0.

    Analysis of Level 3:
    - If the dog is at level 3, the optimal move for Sheldon would be to make the dog jump down 1 level.
    - This would lead the dog to level 2, where Kripke would have no choice but to bring the dog down by 1 level.
    - This would result in the dog being at level 1, where Sheldon can make the dog jump down 1 level to reach level 0 and win the game.

    Conclusion:
    - Therefore, Sheldon should not command the dog to jump down to level 3 to ensure he wins the game.

    Directions:The passage below is accompanied by a set of questions. Choose the best answer to each question.The young scientist in India is an endangered species. The threat comes from the predatory habits of a more evolved species that is the senior scientist. An Indian university teacher in a letter to the international science journalNaturewrote plaintively: Thesis supervisors take undue credit for the work of their protégés. A young scientist needs the goodwill and support of the scientist-in-power at every step: for completion and continuation of his work, for participation in national and international meetings and research projects, for recognition and reward and for promotion. This support is available but at a price. The price often is the sharing of credit. A worthwhile research paper or a project originating from a humble scientist would often end up with the scientist-in-power as the principal author or investigator.The power of the senior scientist over his junior stems from the fact that science is the only profession in the world which is self-assessing. Unlike in the bureaucracy or the military where the top authority vests with non-professionals, a scientists work can be overseen and evaluated only by fellow scientists.Fortunately for the scientists, support for science is a badge of honour for nations aspiring to modernity. That is why the government which normally would not pay the piper unless it can call the tune, happily makes an exception in the case of science. Society values continuity, stability and security, and turns to the past for guidance and support. Science, on the other hand, aspires to instability. It aims at creating something that did not exist before. It seeks a break with the past with an eye on the future.It is an irony that in todays world, feudalism can be sustained only in the administration of a modern scientific research centre. One must, however, not be unfair to the feudal lords of yesteryears whose conduct had the sanction of the times. Neo-feudalism is pernicious because it is anachronistic; it can be sustained only by a subversion of the system in the hands of the people who are entrusted with the task of upholding it.If we define professionalism as the realisation that an institution ranks higher than an individual and that the collective goal is more important than individual ego, it must be admitted that we are unprofessional people. It is wrong in principle to give any individual a larger-than-the-institution image. This philosophy becomes all the more debilitating, because recently there has been an alarming decline in the quality of leadership in science as in other walks of life. It is relatively speaking an easy matter to evaluate a leader. His commitment can be judged by asking whether he is giving to the system or taking from it. The calibre of a leader can be gauged from the calibre of the people willing to play second fiddle to him.Under these circumstances, if a chief executive is to be projected as the master of an institution rather than its servant, this can be done only by degrading the institution. It will be like a cinema hall whose facade remains the same, but the posters outside and the picture inside go on changing.Q.The author suggests that the power which a senior scientist exercises over his juniors is due to

    DIRECTIONSfor the question:Read the passage and answer the question based on it.DISMAL may not be the most desirable of modifiers, but economists love it when people call their discipline a science. They consider themselves the most rigorous of social scientists. Yet whereas their peers in the natural sciences can edit genes and spot new planets, economists cannot reliably predict, let alone prevent, recessions or other economic events. Indeed, some claim that economics is based not so much on empirical observation and rational analysis as on ideology.In October Russell Roberts, a research fellow at Stanford Universitys Hoover Institution, tweeted that if told an economists view on one issue, he could confidently predict his or her position on any number of other questions. Prominent bloggers on economics have since furiously defended the profession, citing cases when economists changed their minds in response to new facts, rather than hewing stubbornly to dogma. Adam Ozimek, an economist at Moodys Analytics, pointed to Narayana Kocherlakota, president of the Federal Reserve Bank of Minneapolis from 2009 to 2015, who flipped from hawkishness to dovishness when reality failed to affirm his warnings of a looming surge in inflation. Tyler Cowen, an economist at George Mason, published a list of issues on which his opinion has shifted (he is no longer sure that income from capital is best left untaxe d). Paul Krugman, an economist and New York Times columnist, chimed in. He changed his view on the minimum wage after research found that increases up to a certain point reduced employment only marginally (this newspaper had a similar change of heart).Economists, to be fair, are constrained in ways that many scientists are not. They cannot brew up endless recessions in test tubes to work out what causes what, for instance. Yet the same restriction applies to many hard sciences, too: geologists did not need to recreate the Earth in the lab to get a handle on plate tectonics. The essence of science is agreeing on a shared approach for generating widely accepted knowledge. Science, wrote Paul Romer, an economist, in a paper published last year, leads to broad consensus. Politics does not.Nor, it seems, does economics. In a paper on macroeconomics published in 2006, Gregory Mankiw of Harvard University declared: A new consensus has emerged about the best way to understand economic fluctuations. But after the financial crisis prompted a wrenching recession, disagreement about the causes and cures raged. Schlock economics was how Robert Lucas, a Nobel-prize-winning economist, described Barack Obamas plan for a big stimulus to revive the American economy. Mr Krugman, another Nobel-winner, reckoned Mr Lucas and his sort were responsible for a dark age of macroeconomics.As Mr Roberts suggested, economists tend to fall into rival camps defined by distinct beliefs. Anthony Randazzo of the Reason Foundation, a libertarian think-tank, and Jonathan Haidt of New York University recently asked a group of academic economists both moral questions (is it fairer to divide resources equally, or according to effort?) and questions about economics. They found a high correlation between the economists views on ethics and on economics. The correlation was not limited to matters of debate" how much governments should intervene to reduce inequality, say" but also encompassed more empirical questions, such as how fiscal austerity affects economies on the ropes. Another study found that, in supposedly empirical research, right-leaning economists discerned more economically damaging effects from increases in taxes than left-leaning ones.That is worrying. Yet is it unusual, compared with other fields? Gunnar Myrdal, yet another Nobel-winning economist, once argued that scientists of all sorts rely on preconceptions. "Questions must be asked before answers can be given," he quipped. A survey conducted in 2003 among practitioners of six social sciences found that economics was no more political than the other fields, just more finely balanced ideologically: left-leaning economists outnumbered right-leaning ones by three to one, compared with a ratio of 30:1 in anthropology.Q.According to the information given in the passage:I. Scientists and economists are similar.II. Scientists and economists are not similar.III. Scientists are more accurate than economists.IV. Scientists are less disputative that economists.
