Climate change in the form of global warming refers to the rise in average surface temperatures on Earth. The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires. Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases. While some quantities of these gases are a naturally occurring and critical part of Earth’s temperature control system, the atmospheric concentration of carbon dioxide did not rise above 300 parts per million between the advent of human civilization roughly 10,000 years ago and 1900. Today it is at about 400 ppm, a level not reached in more than 400,000 years. I.

Traffic congestion or traffic jam is one of the biggest problems of urban India. The main cause of traffic congestion is the country’s public transport infrastructure, which is failing to keep up with the rapidly growing developments in the cities. There is an estimated one lakh motorized vehicles travelling on Delhi roads per day. All this has not only led to obvious delays and jams, but a high rate of accidents as well as increased air and noise pollution. National Road Safety Council has been trying to formulate road safety policy since 1988. Road safety policies were again attempted in 2003 by the Ministry of Highways and Transport and in 2004 at the Annual Session of Indian Roads Congress, the ministry introduced eleven elements for road safety policies under the title ‘Safer Roads for Everyone’. These elements include the overall framework for road safety, safety education and enforcement of the policies. There are a number of initiatives that have already been set up in different parts of the country to relieve the problem of congestion. The Intelligent Transport System is working to provide safe and accessible public transport for commuters in India. Some examples include advanced traffic management systems, wireless traffic signal controllers, CCTV junction surveillance, electronic toll collection systems, advanced vehicle control systems and video incident detection. I. Main reasons of the traffic congestion in the cities include i. lack of policies ii. lack of infrastructure iii. both i and ii above. II. Main reasons of road accidents include i. inadequate public transport infrastructure ii. rapid urban development iii. both i and ii above. III. In order to reduce traffic congestion, the government emphasizes on i. controlled urban development ii. use of advanced techniques iii. both i and ii above. The correct answers to I, II and III are: A. iii, iii and iii, respectively B. ii, i and iii, respectively C. ii, iii and ii, respectively D. iii, iii and ii, respectively. |
