Which one of the following titles could be most suitable for the passage?

Directions: Read the passage and answer the following question:

            At its recent annual meeting, World Bank officials spoke extensively about corruption. It is an understandable concern: money that the Bank lends to developing countries that ends up in secret bank accounts or finance contactors’ luxurious lifestyles leaves a country more indebted, not more prosperous.
            James Wolfensohn, the Bank’s pervious president and the author were widely credited with putting corruption on the Bank’s agenda, against opponents who regarded corruption as a political issue, not an economic one, and thus outside the Bank’s mandate. Our research showed systematic relationships between corruption and economic growth, which allowed us to pursue this critical issue.
            But the World Bank would do well to keep four things in mind as it takes up the fight. First, corruption takes many forms, so a war on corruption has to be fought on many fronts. You can’t fight the diversion of small amounts of money by weak and poor countries while ignoring the massive diversion of public resources into private hands of the sort that marked, say, Russia under Boris Yeltsin.
            In some countries, overt corruption occurs primarily through campaign contributions that oblige politicians to repay major donors with favours. Smaller scale corruption is bad, but systematic corruption of political process can have even greater costs. Campaign contributions and lobbying that lead to rapid privatization of utilities-before appropriate regulatory frameworks are in place, and in a manner that produces only a few bidders-cans impede developments, even without direct kickbacks to government officials.
            Life is never black and white. Just as there is no “one size fits all” policy for economic development, there is no such policy for fighting corruption. The response for fighting needs to be as complex and variegated as corruption itself.
            Second, it’s fine for the World Bank to deliver anti-corruption summons. But policies, procedures, and institutions are what matter. In fact, the Bank’s procurement procedures are generally viewed around the world as a model to be admired. Indeed, some countries with large dollar reserves-hardly in need of World Bank credit-borrowed from the Bank at far higher interest rates than they were getting from the US, believing that these procedures would help ensure high quality projects free of corruption and become standard in other areas.
            But fighting corruption entails more than just good procurement procedures (avoiding, for instance, single source non competitive bidding). Many other policies and procedures can be enacted that reduce the incentive for corruption. For example, some tax systems are more corruption-resistant than others, because they curtail the discretionary authority of tax officials.
            Third, the World Bank’s primary responsibility to fight poverty, which means that when it plans to assist a poor country plagued with corruption, its challenge is to figure out how to ensure that its own money is not tainted and gets to projects and people that need it. In some cases, this may entail delivering assistance through non-governmental organizations. But seldom will it be the case that best response is simply to be away.
            Finally, while developing countries must take responsibility for rooting out corruption, there is much that the West can do to help. At a minimum, western governments and corporations should not be complicit. Every bribe that is taken has a payer, and too often the bribe payer is a corporation from an advanced industrial country or someone acting on its behalf.
            Indeed, one reason for the so called “natural resource curse”-the fact that resource rich countries do not, on average, do as well as resource poor countries-is the prevalence of corruption , too often added and abetted by companies that would like to get the resources they sell at discount prices. The US under President Jimmy Carter made an important contribution in passing the Foreign Corrupt Practices Act, which made bribery by American companies anywhere in the world illegal. The OECD’s convention on bribery was another step in the right direction. Making all payments to governments transparent would bring further progress, and western governments could encourage this simply by tying this requirements to tax deductibility.
            It is equally important to address bank secrecy, which facilitates corruption by providing corrupt dictators’ wives a safe haven for their funds. In August 2001, just before the terrorist attacks on America, the US government vetoed an OECD effort to limit secret bank accounts. While the government has since reversed its stance on bank secrecy for terrorists, it has not done so for corrupt officials. A strong stand by the World Bank would enhance its credibility in the war on corruption.
            Those who criticize the Bank’s stance on corruption do not so because they favour corruption. Some critics worry about corruption in the corruption agenda itself, that the fight will be used as a “cover” for cutting aid to countries that displease the US administration. Such concerns have found resonance in the seeming incongruity of the Bank’s tough talk on corruption and simultaneous plans to expand lending to Iraq. No one is like to certify that Iraq is corruption free-or even ranks low on corruption internationally.
            The main strident criticism, however comes from those who worry that the Bank is straying away from its mandate. Of course, the Bank must do everything that it can to ensure that its money is well spent, which means fighting both corruption and incompetence.
            But money itself will not solve all problems and a single-minded focus on fighting, corruption will not bring development. On the contrary, it might merely divert attention from other issues of no less important for those struggling to lift themselves out of poverty.

The authors propose all of the following as possibly contributing to the “missing matter” in spiral galaxies Except

Directions: Read the passage and answer the following question:

            After evidence was obtained in the 1920s that the universe is expanding, it became reasonable to ask: will the universe continue to expand indefinitely, or is there enough mass in it for the mutual attraction of its constituents to bring this expansion to a halt? It can be calculated that the critical density of matter needed to break the expansion and “close” the universe, is equivalent to three hydrogen atoms per cubic metre. But the density of the observable universe-luminous matter in the form of galaxies-comes to only a fraction of this. If the expansion of the universe is to stop, there must be enough invisible matter in the universe to exceed the luminous matter in density by a factor of roughly 70.
            Our contribution to the search for this “missing matter” has been to study the rotational velocity of galaxies at various distances from their centre of rotation. It has been known for some time that outside the bright nucleus of typical spiral galaxy luminosity falls off rapidly with distance from the centre. If luminosity is a true indicator of mass, most of the mass would be concentrated toward the centre. Outside the nucleus the rotational velocity would decrease geometrically with the distance from the centre, in conformity with Kepler’s law. Instead we have found that the rotational velocity in spiral galaxies either remains constant with increasing distance from the centre or increases slightly. This unexpected result indicates that the falloff in luminous mass with distance from the centre is balanced by an increase in nonluminous mass.
            Our findings suggest that as much as 90 percent of the mass of the universe is not radiating at any wavelength with enough intensity to be detected on the Earth. Such dark matter could be in the form of extremely dim stars of low mass of large planets like Jupiter, or of black holes, either small of massive. While it has not yet been determined whether this mass is sufficient to “close” the universe, some physicists consider it significant that estimates are converging on the critical value.

  1. Small, dim stars

  2. Massive stars

  3. Massive black holes

  4. Large planets


Correct Option: B
Explanation:

Massive stars is not mentioned in the passage.

According to the passage, which of the following statements(s) is/are true? I. US Government's stance on bank secrecy account, which facilitates corruption by providing corrupt officials with a safe haven for their funds, will limit bank secrecy and thus help fight corruption. II. Contributions to election fund in some countries before election that oblige politicians to repay major donors with favours is a source of overt corruption. III. When the World Bank confronts a poor country plagued with corruption, its challenge is to ensure that its own money is not tainted and gets to projects and people that need it. Only this way the Bank's primary responsibility to fight poverty could be fulfilled.

Directions: Read the passage and answer the following question:

            At its recent annual meeting, World Bank officials spoke extensively about corruption. It is an understandable concern: money that the Bank lends to developing countries that ends up in secret bank accounts or finance contactors’ luxurious lifestyles leaves a country more indebted, not more prosperous.
            James Wolfensohn, the Bank’s pervious president and the author were widely credited with putting corruption on the Bank’s agenda, against opponents who regarded corruption as a political issue, not an economic one, and thus outside the Bank’s mandate. Our research showed systematic relationships between corruption and economic growth, which allowed us to pursue this critical issue.
            But the World Bank would do well to keep four things in mind as it takes up the fight. First, corruption takes many forms, so a war on corruption has to be fought on many fronts. You can’t fight the diversion of small amounts of money by weak and poor countries while ignoring the massive diversion of public resources into private hands of the sort that marked, say, Russia under Boris Yeltsin.
            In some countries, overt corruption occurs primarily through campaign contributions that oblige politicians to repay major donors with favours. Smaller scale corruption is bad, but systematic corruption of political process can have even greater costs. Campaign contributions and lobbying that lead to rapid privatization of utilities-before appropriate regulatory frameworks are in place, and in a manner that produces only a few bidders-cans impede developments, even without direct kickbacks to government officials.
            Life is never black and white. Just as there is no “one size fits all” policy for economic development, there is no such policy for fighting corruption. The response for fighting needs to be as complex and variegated as corruption itself.
            Second, it’s fine for the World Bank to deliver anti-corruption summons. But policies, procedures, and institutions are what matter. In fact, the Bank’s procurement procedures are generally viewed around the world as a model to be admired. Indeed, some countries with large dollar reserves-hardly in need of World Bank credit-borrowed from the Bank at far higher interest rates than they were getting from the US, believing that these procedures would help ensure high quality projects free of corruption and become standard in other areas.
            But fighting corruption entails more than just good procurement procedures (avoiding, for instance, single source non competitive bidding). Many other policies and procedures can be enacted that reduce the incentive for corruption. For example, some tax systems are more corruption-resistant than others, because they curtail the discretionary authority of tax officials.
            Third, the World Bank’s primary responsibility to fight poverty, which means that when it plans to assist a poor country plagued with corruption, its challenge is to figure out how to ensure that its own money is not tainted and gets to projects and people that need it. In some cases, this may entail delivering assistance through non-governmental organizations. But seldom will it be the case that best response is simply to be away.
            Finally, while developing countries must take responsibility for rooting out corruption, there is much that the West can do to help. At a minimum, western governments and corporations should not be complicit. Every bribe that is taken has a payer, and too often the bribe payer is a corporation from an advanced industrial country or someone acting on its behalf.
            Indeed, one reason for the so called “natural resource curse”-the fact that resource rich countries do not, on average, do as well as resource poor countries-is the prevalence of corruption , too often added and abetted by companies that would like to get the resources they sell at discount prices. The US under President Jimmy Carter made an important contribution in passing the Foreign Corrupt Practices Act, which made bribery by American companies anywhere in the world illegal. The OECD’s convention on bribery was another step in the right direction. Making all payments to governments transparent would bring further progress, and western governments could encourage this simply by tying this requirements to tax deductibility.
            It is equally important to address bank secrecy, which facilitates corruption by providing corrupt dictators’ wives a safe haven for their funds. In August 2001, just before the terrorist attacks on America, the US government vetoed an OECD effort to limit secret bank accounts. While the government has since reversed its stance on bank secrecy for terrorists, it has not done so for corrupt officials. A strong stand by the World Bank would enhance its credibility in the war on corruption.
            Those who criticize the Bank’s stance on corruption do not so because they favour corruption. Some critics worry about corruption in the corruption agenda itself, that the fight will be used as a “cover” for cutting aid to countries that displease the US administration. Such concerns have found resonance in the seeming incongruity of the Bank’s tough talk on corruption and simultaneous plans to expand lending to Iraq. No one is like to certify that Iraq is corruption free-or even ranks low on corruption internationally.
            The main strident criticism, however comes from those who worry that the Bank is straying away from its mandate. Of course, the Bank must do everything that it can to ensure that its money is well spent, which means fighting both corruption and incompetence.
            But money itself will not solve all problems and a single-minded focus on fighting, corruption will not bring development. On the contrary, it might merely divert attention from other issues of no less important for those struggling to lift themselves out of poverty.

Explanation:

  When the World Bank confronts a poor country plagued with corruption, its challenge is to ensure that its own money is not tainted and gets to projects and people that need it. Only this way the Bank's primary responsibility to fight poverty could be fulfilled.

The passage suggests that the results of the authors' study have changed their idea about which of the following characteristics of spiral galaxies ? I. The relative luminosity of different regions II. The different rotational velocity of different regions III. The relative distribution of matter in different regions

Directions: Read the passage and answer the following question:

            After evidence was obtained in the 1920s that the universe is expanding, it became reasonable to ask: will the universe continue to expand indefinitely, or is there enough mass in it for the mutual attraction of its constituents to bring this expansion to a halt? It can be calculated that the critical density of matter needed to break the expansion and “close” the universe, is equivalent to three hydrogen atoms per cubic metre. But the density of the observable universe-luminous matter in the form of galaxies-comes to only a fraction of this. If the expansion of the universe is to stop, there must be enough invisible matter in the universe to exceed the luminous matter in density by a factor of roughly 70.
            Our contribution to the search for this “missing matter” has been to study the rotational velocity of galaxies at various distances from their centre of rotation. It has been known for some time that outside the bright nucleus of typical spiral galaxy luminosity falls off rapidly with distance from the centre. If luminosity is a true indicator of mass, most of the mass would be concentrated toward the centre. Outside the nucleus the rotational velocity would decrease geometrically with the distance from the centre, in conformity with Kepler’s law. Instead we have found that the rotational velocity in spiral galaxies either remains constant with increasing distance from the centre or increases slightly. This unexpected result indicates that the falloff in luminous mass with distance from the centre is balanced by an increase in nonluminous mass.
            Our findings suggest that as much as 90 percent of the mass of the universe is not radiating at any wavelength with enough intensity to be detected on the Earth. Such dark matter could be in the form of extremely dim stars of low mass of large planets like Jupiter, or of black holes, either small of massive. While it has not yet been determined whether this mass is sufficient to “close” the universe, some physicists consider it significant that estimates are converging on the critical value.

What the author meant by so called “natural resource curse” in his argument to fight against corruption? I. Countries poor in natural resources )e.g. fossil fuel, minerals, etc.) are necessarily poor and it becomes “natural curse” for these countries. Such countries become victims of corruption. II. Oil-rich countries in the Middle East support corruption in allocating oil exploration contracts and as such natural resource becomes a curse for these countries. III.The fact that resource rich countries do not, on average, do well as resource poor countries, is the prevalence of corruption, too often aided and abetted by countries that would like to get the resources they sell at discount prices.
