Read the information given below carefully and answer.

Culture was not incorporated the Millennium Development Goals or their indicators, alleging numerous difficulties to measure its impact on development. However, one of the reasons why the goals set in the year 2000 were not met is probably the failure to explicitly recognize the role of culture in economic growth, resource management, conflict resolution, the approach to social inequities, or the reaffirmation of identities. Nor was it understood at the time that culture is an extremely effective vector for the transmission of knowledge and the basis for innovation and creation, including scientific breakthroughs. It was ignored, perhaps, that there is no one single development recipe, as cultures need to determine their development models, and not the other way around.

Almost a decade after the onset of the global financial crisis, national debt in advanced economies remains near its highest level since World War II, averaging 104 percent of GDP. Without measures either to cut spending or increase revenue, the situation will only get worse. As central banks abandon the extraordinary monetary measures, they adopted to battle the crisis, interest rates will inevitably rise from historic lows. That means interest payments will eat up a growing share of government spending, leaving less money to deliver public services or take steps to ensure long term economic growth, such as investing in infrastructure and education. Servicing debt will become a major burden.

The world faces a looming water disaster, one that could dry out our food systems. Even as climate change disrupts rainfall patterns, global water demand is projected to increase by 55% by 2050. While agriculture is not the only driver of increased water demand, the world's growing population will need more food, putting further strain on already limited water resources - resources that do not enter into the market value of the food on our plates. This scarcity of water can in turn cause shortage of food supply in the world.

Recently some scientists have concluded that meteorites found on Earth and long believed to have a Martian origin might actually have been blasted free of Mars’s gravity by the impact on Mars of other meteorites. This conclusion has led to another question whether meteorite impacts on Earth have similarly driven rocks from this planet to Mars. According to astronomer S. A. Phinney, kicking a rock hard enough to free it from Earth’s gravity would require a meteorite capable of making a crater more than 60 miles across. Moreover, even if Earth rocks were freed by meteorite impact, Mars’s orbit is much larger than Earth, So Phinney estimates that the probability of these rocks hitting Mars is about one-tenth as great as that of Mars’s rocks hitting Earth. To demonstrate this estimate, Phinney used a computer to calculate where 1,000 hypothetical particles would go if ejected from Earth in random directions. He found that 17 of the 1,000 particles would hit Mars.
