Sample Answer 1:

The graph shows how the amount of water used worldwide changed between 1900 and 2000 and water consumptions of two countries compared to their population.

Throughout the century, the largest quantity of water was used for agricultural Purposes, and this increased dramatically from about 500 km³ to around 3,000 km³ in the year 2000. Water used in the industrial and domestic sectors also increased, but consumption was minimal until mid-century. From 1950 onwards, industrial use grew steadily to just over 1,000 km³, while domestic use rose more slowly to only 300 km³, both far below the levels of consumption by agriculture.

The table illustrates the differences in agriculture consumption in some areas of the world by contrasting the amount of irrigated land in Brazil (26,500 km³) with that in the D.R.C. (100 km²). This means that a huge amount of water is used in agriculture in Brazil, and this is reflected in the figures for water consumption per person: 359 m³ compared with only 8 m³ in the Congo. With a population of 176 million, the figures for Brazil indicate how high agriculture water consumption can be in some countries.

Sample Answer 2:

The given graph shows the water consumption in different sectors and how water usage changes rapidly from 1900 to 2000. It also compares the consumption of water in the agriculture sector in two different countries according to their population.
Throughout the century, the highest water consumption could be observed in agricultural sector respectively which was initially 500 km³ and rose steadily approximately to 3000 km³ respectively. Usage of water recorded at a minimal level in 1900 and it remained same in half of the century. In 1950 and onwards, water consumption in industrial sector grew significantly to over 1000 km³ while in domestic sector slightly increment in water usages can be seen which was about only 300 km³.

The given table illustrates the water consumption in different areas of the world. Irrigated land in Brazil was 26,500 km2 with the population of 176 million and water consumption per person was 359 m³ whereas D.R.C possesses 100 km2 irrigated land with the lowest number of population (only 5.2 million) and they consumed 8 m³  water per person respectively. Moreover, Brazil consumed more water while Congo consumed less water in irrigated lands.
