Short Q/A
A1- Only three percent of water is fresh water, in which two percent is frozen in glaciers and polar ice caps.97 percent of the water is salty ocean water. So only one percent of the water is available for drinking.

A2. Because only one percent of water is available for drinking.

A3- Because people had access to fresh water easily.

A4- The Indus Valley Civilization period had one of the most sophisticated urban water supply and sewage system in the world.

A5- In the forest water seeps gently into the ground as vegetation breaks the flow of water. This ground water feeds well, lakes and rivers.

A6- Because the level of underground water is falling sharply day by day.

A7- He admitted that groundwater was continuously declining in 85% areas of the state.

A8- Due to excessive decline in water, nitrate presence in water has gone up by ten times and farmers have to dig deeper into the ground to pump out water.

A9- Technologies like planting and a planting time of crops, sprinklers, drip irrigation and furrow. Can be used to save water.

A10- In villages, people have to go for miles to collect water from tanks and lakes. The poor urban classes have to drink polluted water.

Long Q/A

A2- Water conservation has become the need of the day because rising population, growing industrialization and expanding agriculture have pushed up the demand for water. Besides this, we are also wasting and polluting water. We are cutting down our forests. It disturbed the water cycle also. As a result the water level is sinking year after year. And if this continuous, a day will come when life would become impossible on the earth. So we will have to conserve every drop of water.

A5. Water is the foundation of food and life. It is the basis of all life. We can live without food for a number of days but we can’t do without water for a day even. It is essential to life as air. In the forest water seeps gently into the ground as vegetation breaks the flow of water. This ground water feeds well, lakes and rivers .Many poets are inspired by falling of water down the hills. But with the advancement we are wasting and polluting water. We are cutting down our forests. It disturbed the water cycle also. As a result the water level is sinking year after year. And if this continuous, a day will come when life would become impossible on the earth. So we will have to conserve every drop of water.

READING (PASSAGE)
In the state of Punjab major share of water is taken by rice-wheat cropping system. It may be noticed that 1 kilogram of rice consumes 3500-4000 liters of water for its growth (depending upon its variety, sowing time, area, etc.). Therefore, it is the requirement of the present situation that the traditional cropping pattern should be changed immediately. Moreover, there is a need to strictly switch over to the technologies related to soil and agronomic management that save water without a loss in crop yields, leading to higher productivity per unit use of water. These technologies include planting and Ansplanting time of crops, irrigation scheduling and new irrigation methods, (e.g. sprinkler, drip, furrow etc.) For using available water resources effectively and efficiently, water users' associations/societies should be constituted. Various measures/ technologies for enhancing artificial groundwater recharge should also be adopted. We must hear the warning bells and act before it is too late. Every drop of water is precious and needs to be saved wherever and in whatever way it is possible.

Questions 1-3
Do the following statements agree with the writer in the Reading Passage?

Write TRUE, if the statement is true.
Write FALSE, if the statement is false.
Write NOT GIVEN, if the statement is not given.

1 Traditional cropping pattern should be preserved.
2 Artificial groundwater recharging systems are widely adopted by the farmers in Punjab.
3 Water consumers associations should be formed to preserve water resources.
