Directions (Q. 1-10): Read the passage carefully and answer the questions given below it. Certain words/phrases are given in bold to help you locate them while answering some of the questions.
For a look at what climate change could do to the world's food supply, consider what the weather did to the American Corn Belt last year.
At the beginning of 2012, the Agriculture Department projected the largest corn crop in the country's history. But then a savage heat wave and drought struck over the summer. Plants withered, prices  spiked, and the final harvest came in 27 per cent below the forecast.
The situation bore a striking resemblance to what happened in Europe in 2003, after a heat wave cut  agricultural production for some crops by as much as 30 per cent and sent prices soaring.
Several researchers concluded that the European heat wave was made more likely by human-caused climate change; scientists are still arguing over the 2012 heat blast in the United States. Whatever their origin, heat waves like these give us a taste of what could be in store in a future with global warming.
"The negative impacts of global climate change on agriculture are only expected to get worse," said  a report earlier this year from researchers at the London School of Economics and a Washington think tank, the Information Technology & Innovation Foundation. The report cited a need for "more  resilient crops and agricultural production systems than we currently possess in today's world".
This may be the greatest single fear about global warming: that climate change could so destabilise the world's food system as to lead to rising hunger or even mass starvation. A leaked draft of a report by the United Nations climate committee, known as the Intergovernmental Panel on Climate Change, suggested that the group's concerns have grown, and that the report, scheduled for release in March, is likely to contain a sharp warning about risks to the food supply.
The tone is strikingly different from that of a report from the same group in 2007, which discussed some risks, but saw global warming as likely to benefit agriculture in many important growing regions. In the years since, new scientific research has checked those assumptions.
For one, a group of young scientists has pioneered more  sophisticated ways of analysing the relationship between agriculture and climate. People like David Lobell at Stanford and Wolfram Schlenker at Columbia have used elaborate statistical techniques to get a detailed picture of what heat does to crop yields.
Their work suggests that rising heat stress in some major growing areas is already putting a drag on production, and raises the possibility of much more serious effects as global warming continues.
Scientists had long hoped that the effect of heat and water stress on crops might be offset by the very thing driving global warming: the sharp increase of carbon dioxide in the air. The gas is the main food supply for plants, and a large body of evidence suggested that the ongoing rise could boost crop yields.
But a lot of that evidence came from tests in artificial environments like greenhouses. Younger scientists, who insisted on testing crops in open-air conditions more closely resembling the real world, found that the bump in yield, while certainly real, was not as high as expected. And it may not be high enough to offset other stresses from global warming. The good news is that agriculture has a tremendous capacity to adapt to new conditions, including a warming climate. Crops can be planted earlier, and new varieties that are more resistant to climate stress can be developed.
"Our past successes in agriculture have  lulled many of those in decision making positions into a false sense of security," said LVal Giddings, a fellow with the Washington think tank and a co-author of its report. "It's been so long since any of them were actually hungry."
