Part of what makes summers so hot is also what causes thunderstorms. As heat from the sun beats down on Earth, the heat evaporates some of the water in lakes and oceans.

Warm humid air usually does not stay in one place. The wind can move it higher in the sky (2) _______ it will cool off. When warm humid air cools, it forms clouds. As more water is moved from lakes and oceans to the airs, the clouds get bigger and bigger. 

Since summer, the air near the ground is hotter than it is during other seasons of the year. When this hot air mixes with cool air from (3) _______ area, there will be changes in the weather. Greater differences between the (4) _______ of the hot and cold air will cause greater changes in the weather. Imagine putting an ice (5) _______ in a warm drink. As soon as the ice hits the warm drink, it will crack and pop. But if you put the ice cube in a cool drink, it will not crack or pop as much. When warmer and cooler clouds get close to one another, there may be some popping and cracking as the weather changes. There may be more clouds or storms. A thunderstorm may be on its way

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. 

     It is estimated that by 2050 more than two-thirds of the world's population will live in cities, up from about 54 percent today. While the many benefits of organized and efficient cities are well understood, we need to recognize that this rapid, often unplanned urbanization brings risks of profound social instability, risks to critical infrastructure, potential water crises and the potential for devastating spread of disease. These risks can only be further exacerbated as this unprecedented transition from rural to urban areas continues. 

     How effectively these risks can be addressed will increasingly be determined by how well cities are governed. The increased concentration of people, physical assets, infrastructure and economic activities mean that the risks materializing at the city level will have far greater potential to disrupt society than ever before. 

     Urbanization is by no means bad by itself. It brings important benefits for economic, cultural and societal development. Well managed cities are both efficient and effective, enabling economies of scale and network effects while reducing the impact on the climate of transportation. As such, an urban model can make economic activity more environmentally-friendly. Further, the proximity and diversity of people can spark innovation and create employment as exchanging ideas breeds new ideas. But these utopian concepts are threatened by some of the factors driving rapid urbanization. For example, one of the main factors is rural urban migration, driven by the prospect of greater employment opportunities and the hope of a better life in cities. But rapidly increasing population density can create severe problems, especially if planning efforts are not sufficient to cope with the influx of new inhabitants. The result may, in extreme cases, be widespread poverty. Estimates suggest that 40% of the world's urban expansion is taking place in slums, exacerbating socio-economic disparities and creating unsanitary conditions that facilitate the spread of disease.

          The Global Risks 2015 Report looks at four areas that face particularly daunting challenges in the face of rapid and unplanned urbanization: infrastructure, health, climate change, and social instability. In each of these areas we find new risks that can best be managed or, in some cases, transferred through the mechanism of insurance
