For millions of people in India, river Ganga is the most sacred river. It is considered as a mother and goddess. It is also a lifeline to millions of Indians who live on the banks of its course and depend on it for their daily needs. River Ganga is the third largest river in the world by the amount of water that flows through it. It is the longest river in India. The river water of Ganga is used for irrigation, transportation, and fishing. The Gangetic plain formed by river Ganga is one of the most fertile lands on earth. This is why almost 10% of the world population lives here and earns its livelihood. The Ganga, in India, is the most worshipped body of water. The irony here is that in spite of being the most worshipped river, it is also the dirtiest one. It carries metals thrown out by tanneries, waste produced by industries, and urban waste from different cities. All this has made the river Ganga, the fifth most polluted river in the world. Another major reason that adds to the Ganga river pollution is the coal-based power plants on its banks which burn tons of coal every year and produce a lot of fly ash. This ash mixed with domestic wastewater is released in the river. This bad situation calls for an urgent need to make efforts to reduce pollution and revive river Ganga. To achieve these objectives, the Government of India has started a program named "Namami Gange Program". The main pillars of this program are sewage treatment, river surface cleaning, afforestation, riverfront development, and public awareness. The importance of the success of the "Namami Gange Program" can be seen through the following lines: Ganga dies, India dies. If Ganga thrives, India thrives. No Ganga, No India.
The correct answer is option B, i.e., reduction of pollution and revival of the river. This is the evident from the lines "To achieve these objectives, the Government of India has started a program named "Namami Gange Programme". The main pillars of this program are sewage treatment, river surface cleaning, afforestation, riverfront development, and public awareness."
The correct answer is option B, i.e., Selective Listening. In this type of listening, one hears only what one wanted to hear. In this phenomenon, usually a lot of voices are heard by the brain and the brain tries to filter what is more important and concentrates only on that. This filtering can also be due to the fact that the information or opinions being heard do not agrees with our own opinions and thus the brain ignores it.
