Read the following passage carefully and give the answer of following questions.

The problem of water pollution by pesticides can be understood only in context, as part of the whole to which it belongs – the pollution of the total environment of mankind. The pollution entering our waterways comes from many sources, radioactive wastes from reactors, laboratories and hospitals; fallout from nuclear explosions; domestic wastes from cities and towns; chemical wastes from factories. To these is a added a new kid of fallout - the chemical sprays applied to crop lands and gardens, forests and fields. Many of the chemical agents in this alarming melange initiate and augment the harmful effects of radiation, and within the groups of chemicals themselves there are sinister and little - understood interactions, transformations and summations of effect.

Ever since the chemists began to manufacture substances that nature never invented, the problem of water purification have become complex and the danger to users of water has increased. As we have seen, the production of these synthetic chemicals in large volume began in the 1940’s. It has now reached such proportion that an appalling deluge of chemical pollution is daily poured into the nation’s waterways. When inextricably mixed with domestic and other wastes discharged into the same water, these chemicals sometimes defy detection by the methods in ordinary use by purification plants. Most of them are so complex that they cannot be identified. In rivers, a really incredible variety of pollutants combine to produce deposits that sanitary engineers can only despairingly refer to as “gunk”.

Water contamination has become serious:

Long ago men spent most of their time looking for food. They ate anything they could find. Some lived mostly on plants. They ate the fruit, stems, and leaves of some plants and the roots of others. When food was scarce, they ate the bark of trees. If they were lucky, they would find a bird’s nest with eggs. People who lived near the water ate fish or anything that washed ashore, even rotten whales. Some people also ate insects and small animals like lizards that were easy to kill.

Later, men learned to make weapons. With weapons, they could kill larger animals for meat. These early people had big appetites. If they killed an animal, they would drink the blood, eat the meat, and chew the bones. When they finished the meal, there was nothing left.

At first men wandered from place to place to find their food. But when they began to grow plants, they stayed in one place and ate what they could grow. They tamed animals, trained them to work, and killed them for meat. Life was a little better then, but there was still not much variety in their meals. Day after day people ate the same food.

Gradually men began to travel greater distances. The explorers who sailed unknown seas found new lands. And in these lands they found new food and spices and took them back home.

The Portuguese who sailed around the stormy Cape of Good Hope to reach China took back “Chinese apples”, the fruit we call oranges today. Later, Portuguese colonists carried orange seeds to Brazil. From Brazil oranges were brought to California, the first place to grow oranges in the United States. Peaches and melons also came from China. So did a new drink, tea.

What does the word stormy in the expression the stormy Cape of Good Hope mean?

Can the last fifteen years be called the most successful decade and a half in Indian history and will the next fifteen be equally successful? Consider a culture where independent thinking is not encouraged. Or take the example of traditional family run business with vast resistance to change or a whole nation who believes that breakthrough ideas can be generated abroad but never at home. Partly responsible is socialization from early years we are taught not to question our elders but at workplaces this creates a hurdle for new thinking. Being unable to change radically gives rise to a culture where even the smallest change is heralded as a break through. Indian corporate leaders have done well standing up to global giants as their companies have grown in size and market share. To be successful in international markets they need to be distinct distinct products, processes, technologies, business models and organisations. The bottom line will be Innovation. Creativity workshops are organized to channel people to think differently. There are fantastic ideas being generated all the time but no Industry. breakthrough. Simply because of gravity regressive force exerted by a mindset. Thinking has therefore to happen at three, levels idea, frame and paradigm. From a narrow focus on either product or process innovation organizations need to look at innovating the whole ecosystem of the organization. Many a time waiting for a hundred percent solution before going to the market the organization forgets that it could end up waiting forever. Moreover, sometimes organizations are too focused on today to see tomorrow. Since management mandates are short-term, sowing the seed for a revenue stream today and leaving Its benefits to be reaped by a successor doesn’t appeal to today’s business leader. This is a serious hurdle to into Ovation. Establishing a function called innovation management or training employees through creativity workshops will have few benefits unless each frontline employee is empowered to Share his innovative ideas with the management. What happens to this system when the person driving the change leaves the organization? The approach to innovation hence needs to be system driven rather than people driven. In thirty years, India can be the largest world economy save China and the US. However, as companies grow there exists a resemblance in their products, services, promotions, processes and pricing and so on. There remains only one escape from this trap. 

Which of the following is NOT TRUE in the context of the passage? 

Read the following passage carefully and give the answer of following questions.

The cyber–world is ultimately ungovernable. This is alarming as well as convenient; sometimes, convenient because alarming. Some Indian politicians use this to great advantage. When there is an obvious failure in governance during a crisis they deflect attention from their own incompetence towards the ungovernable. So, having failed to prevent nervous citizens from fleeing their cities of work by assuring them of proper protection, some national leaders are now busy trying to prove to one another, and to panic-prone Indians, that a mischievous neighbour has been using the internet and social networking sites to spread dangerous rumours. And the Centre's automatic reaction is to start blocking these sites and begin elaborate and potentially endless negotiations with Google, Twitter and Facebook about access to information. If this is the official idea of prompt action at a time of crisis among communities, then Indians have more reason to fear their protectors than the nebulous mischief-makers of the cyber world. Wasting time gathering proof, blocking vaguely suspicious websites, hurling accusations across the border and worrying about bilateral relations are ways of keeping busy with inessentials because one does not quite known what to do about the essentials of a difficult situation. Besides, only a fifth of the 245 websites blocked by the Centre mention the people of the Northeast or the violence in Assam. And if a few morphed images and spurious texts can unsettle an entire nation, then there is something deeply wrong with the nation and with how it is being governed. This is what its leaders should be addressing immediately, rather than making a wrongheaded display of their powers of censorship.
 It is just as absurd, and part of the same syndrome, to try to ban Twitter accounts that parody despatches from the Prime Minister's Office. To describe such forms of humour and dissent as "misrepresenting" the PMO–as if Twitter would take these parodies for genuine despatches from the PMO — makes the PMO look more ridiculous than its parodists manage to. With the precedent for such action set recently by the chief minister of West Bengal, this is yet another proof that what Bengal thinks today India will think tomorrow. Using the cyber–world for flexing the wrong muscles is essentially not funny. It might even prove to be quite dangerously distracting.

Governments have traditionally equated economic progress with steel mills and cement factories. While urban centres thrive and city dwellers get rich, hundreds of millions of famers remain mired in poverty. However fears of food shortages, a rethinking of anti-poverty priorities and crushing recession in 2008 are causing a dramatic shift in world economic policy in favour of greater support for agriculture.  last time when the world's farmers felt such love was in the 1970's. At that time, as food prices spiked, there was real concern that the world was facing a crisis in which the planet was simply unable to produce enough grain and meat for an expanding population. Governments across the developing world and international aid organisations plowed investment agriculture in technological breakthroughs, like high-yield strains of important food crops, boosted production. The result was the Green Revolution and food production exploded. into the early 1970s, while But the Green Revolution became a victim of its own success. Food prices plunged by some 60% by the late 1980's from their peak in the mid- 1970's. Policy-makers and aid workers turned their attention to the poor's other pressing needs, such as health care and education. Farming got starved of resources and investment. By 2004's aid directed at agriculture sank to 3.5% and "agriculture lost its glitter", “Also, as consumers in high-growth giants such as China and India became wealthier, they began eating more meat. So grain once used for human consumption got diverted to beef up livestock. By early 2008, panicked buying by importing countries and restrictions slapped on grain exports by some big producers helped drive prices up to heights not seen for three decades. Making matters worse, land and resources got reallocated to product cash crop such as bio fuels and the result was that voluminous reserves of grain evaporated. Protests broke out across the emerging world and fierce food riots toppled governments.

What motivated the US to focus on investing in agriculture across the globe?

Tens of thousands of people who lost their homes in a catastrophic earthquake huddled around campfires in the bitter cold and clamoured for food and water on Thursday, three days after the temblor hit Turkey and Syria and killed more than 19,300 on Monday, 6th February, 2023.

Emergency crews used pick axes, shovels and jackhammers to dig through twisted metal and concrete - and occasionally still pulled out survivors. In the Turkish city of Antakya, dozens scrambled for aid in front of a truck distributing children's coats and other supplies. Many of those who lost their homes found shelter in tents, stadiums and other temporary accommodation, but others slept outdoors. In Antakya, over 100 bodies were awaiting identification in a makeshift morgue outside a hospital.

Authorities called off search-and-rescue operations in the cities of Kilis and Sanliurfa, where destruction was not as severe as in other impacted regions. The U.N. is authorised to deliver aid through only one border crossing, and road damage has prevented that thus far. U.N. Officials pleaded for humanitarian concerns to take precedence over wartime politics.

The scale of loss and suffering remained massive. Turkish authorities said on Thursday that the death toll had risen to more than 16,100 in the country, with more than 64,000 injured. In Syria, which includes government-held and rebel-held areas, more than 3,100 have been reported dead and more than 5,000 injured.

Rescue teams urged quiet in the hope of hearing stifled pleas for help, and the Syrian paramedic group known as the White Helmets noted that every second could mean saving a life. But more and more often, the teams pulled out dead bodies.

It was not clear how many people were still unaccounted for in both countries. Turkey's disaster-management agency said more than 110,000 rescue personnel were now taking part in the effort and more than 5,500 vehicles, including tractors, cranes, bulldozers and excavators had been shipped.

The Foreign Ministry said 95 countries have offered help. More than half of that number have sent a total of nearly 6,500 rescuers. Another 2,400 more are still expected to arrive. International aid for Syria was far more sparse.

Efforts there have been hampered by the civil war and the isolation of the rebel-held region along the border that is surrounded by Russia-backed government forces.

Why is the International aid much lesser in Syria than in Turkey?

Read the following passage carefully and give answer the following questions.
Two hundred years after Malthus predicted that population growth would overtake food production by a margin of 256 to 9, the simple fact is that food production had always been ahead of the population growth. Malthus’ doomsday prediction simply did not come true due to two major reasons: first, population did not grow geometrically and birth rates in all Western countries fell during the 20- Century, resulting in very slow population growth. Over the past quarter century, birth rates have been falling in the developing countries too. Second, modern agricultural practices and better irrigation have resulted in tremendous growth in food production in almost all parts of the globe, with the notable exception of sub-Saharan Africa. Therefore, at the global level, the Malthusian doomsday never befell on us.
India’s population grew by about two and a half times in the past 45 years — from 361 million in 1951 to an estimated 916 million in 1995. But during the same period, India’s food grain production grew by nearly four times — from 51 million tonnes in 1951 to 191 million tonnes in 1995. As a result, the per capita food grain availability in India has gone up considerably since the Independence. That is, the Malthusian prediction has not come true even in India.

As the Sun inches closer to its peak activity in its solar cycle, an explosion has been picked up behind the north-eastern limb of the star in our solar system. Solar observatories saw bits and pieces of the explosion, which remain obscured in view from Earth's orbit. The explosion was spotted on 31 July at around 2309 UT and Earth-orbiting satellites registered a long-lasting C9.3-class solar flare. "The intensity is probably an underestimate because it was partially eclipsed by the edge of the sun. Nasa's Solar Dynamics Observatory (SDO) saw hot debris flying away from the blast site," space weather, which tracks the solar activity, reported.

While the explosion was powerful, experts have predicted that Earth is not in the line of fire from the Sun. Scientists are expected to get a view of the active region later this week as it comes to sight. Earth is not in the line of fire. The explosion is significant because it may herald an active region set to emerge over the sun's north-eastern limb later this week. A new sunspot group could bring an end to weeks of relative quiet," space weather said in its report
