Directions (Question No . 6 – 10) Read the following excerpt and answer the questions asked The answers to the questions should the questions should be based on the excerpt.
Although water covers approximately sixty seven percent of the Earth’s surface, of this less than three percent is fresh water. Accounting for fresh water locked in glaciere ice-caps or otherwise inaccessible, less than a tenth of a percent of the Earth’s Water is available for human consumption. Pollution, population growth and wasteful irrigation practices are contributing to a worldwide water Shortage. When the clear precious liquid becomes scarce, countries begin to assert claims on fresh water supplies. As a result, drinkable water has become a region of conflict that could eventually lead to greater hostilities between nations.
Some countries such as the United States, have ample sources of water. In other nations, such as China, water is less plentiful. As water resources dwindle, competition for available sources will rise. Nations may claim rights to a particular body of fresh water or they may plan to build dams and other projects on rivers. If two or more nations which disagree on water rights or building projects, conflicts can emerge. In order to combat this issue many countries are adopting water conservation and security solutions. The United Nations has implemented programs to combat potential issues that could lead to violence.
6. What is the main focus of this passage ?
(A) It is important to conserve water because only 3% of the water on earth is drinkable
(B) China will fight with America for controlling fresh water sources
(C) Most fresh water is locked in glaciers and ice-caps
(D) Water is limited and shortages will likely lead to conflicts
7. What percent of surface of earth covered with water is available for human consumption ?
8. Which of the following could be probable reason for hostility among nations in future?
(A) The fact that America has ample sources of water
(B) Assertion of claims on fresh water Supplies in future
(C) China intends to claim on fresh water sources as it has less sources than America
(D) In-equilibrium of arms among various nations
9. Which of the following may definitely not be concluded from the passage ?
(A) Upto about three percent of water may be for human consumption by accounting all possibility
(B) About 97% of water is unusable for human consumption
(C) Water crisis may trigger an arms race among nations in future
(D) Water crisis may possibly end up in creating a hostile relationship among countries
10. What would be the most effective solution to avoid future conflicts among the nations ?
(A) To destroy all weapons
(B) To sign pacts on water rights
(C) To conserve water
(D) To make United Nations a more effective body in handling these issues
11. How many total triangles are there in the following figure ?

Directions (Questions 16 – 20) Read the following excerpt and answer the questions asked at the end. The answer to he questions should be based on the excerpt.
Photographic evidence suggest that liquid water once existed in great quantity on the din great quantity on the surface of Mars. Two types of flow features are seen: runoff channels and outflow channels. Runoff channels in the southern highlands. These flow Features are extensive systems – sometimes hundreds of kilometers in total length – of interconnecting, twisting channels that seem to merge into larger wider channels. They bear a strong resemblance to river systems on Earth and geologists think that they are dried-up beds of long-gone rivers that once carried rainfall on Mars from the mountains down into the valleys. Runoff channels on Mars speak of a time 4 billion years ago (the age of the Martian highlands), when the atmosphere was thicker, the surface warmer and Liquid water widespread.
Outflow channels are probably relics of catastrophic flooding on Mars Tong ago. They appear only in equatorial regions and generally do not form extensive interconnected networks. Instead, they are probably the paths taken by huge volumes of water draining from the southern highlands into the northern plains. The onrushing water arising from these flash floods likely also formed the odd teardrop-shaped “islands” (resembling the miniature versions seen in the wet sand of our beaches at low tide) that have been found on the plains close to the ends of the outflow channels. Judging from the width and depth of the channels, the flow rates must have been truly enormous-perhaps as much as a hundred times greater than the 105 tons per second carried by the great Amazon River. Flooding shaped the outflow channels approximately 3 billion years ago, about the same time as the northern volcanic plains formed.
16. In which of the regions are flow features seen on Mars ?
(A) Western plains
(B) Northern highlands
(C) Southern plains
(D) Southern highlands
17. What does the discussion in paragraph of runoff channels in the southern highlands suggest about Mars ?
(A) The atmosphere of Mars was once thinner than it is today ”
(B) Large amounts of rain once fell on parts of Mars
(C) The river systems of Mars were once more extensive than Earth’s
(D) The rivers of Mars began to dry up about 5 billion years ago
18. The amount of water flowing down the outflow channels on Mars is estimated to be closest to
(A) 105 tons per second
(B) 105 tons
(C) 10500 tons per second
(D) 10500 tons
19. According to paragraph, all of the following are true of the outflow channels on Mars except
(A) They formed at around the same time that volcanic activity was occurring on the northern plains
(B) They are found only on certain parts of the Martian surface
(C) They sometimes empty onto what appear to have once been the wet sands of tidal beaches
(D) They are thought to have carried water northward from the equatorial regions
20. In paragraph, why does the Author include information that 105 tons of water flow through the Amazon River per second ?
(A) To emphasize the great size of the Volume of water that seems to have flowed through Mars’ outflow channels
(B) To indicate data used by scientists to estimate how long ago Mars’ outflow channels were formed
(C) To argue that flash floods on Mars may have been powerful enough to cause tear-shaped “islands” to form
(D) To argue that the force of flood waters on Mars was powerful enough to shape the northern volcanic plains
