    In these questions, the 1st and The last sentence of the passage are numbered 1 and 6. The rest of the passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentences and find out which of the four combinations is correct. 1. The main reason behind Global Warming is the emission of greenhouse gases like carbon dioxide and methane. P. The ozone layer of the earth is depleted by cosmic research resulting in the warming of the atmosphere. Q. Burning of fuels in cars and factories results in the emission of harmful gases in the air. R. Cosmic oriented research work and test fire of atom bombs are also the causes of Global Wanining. S. As a result of the rise in the temperature, polar ice-caps and ice-bergs melt down and the water level in seas and rivers swells. 6. Natural disasters like Tsunami, earthquake may also result from Global Warming.
