The first crisis the lunar explorers faced came just short of moon fall. The Apollo 11 Lunar Module, code – named ‘eagle’, was still 9.5 km (6 miles) up when the vital guidance computer began flashing an alarm. It was overloading. Any second it could give up the ghost under the mounting pressure and nothing the two astronauts could do would save the mission. Emergencies were nothing new to Commander Neil Armstrong but he and his co – pilot Buzz Aldrin hadn’t even practiced for this one on the ground – no one believed it could happen. Sweeping feet first towards their target, they pressed ahead as controllers on Earth waited heart – in – mouth. Racing against the computer, Eagle slowed and then pitched upright to stand on its rocket plume and gave Armstrong his first view of the landing site. The wrong one! They had overshot by four miles into unfamiliar territory and were heading straight for a football field size crater filled with boulders “the size of Volkswagens”. With his fuel running out, and only a minute’s flying time left, Armstrong coolly accelerated the hovering Eagle beyond the crater, touching 88 km/h (55mph). Controllers were puzzled and alarmed by the unplanned manoeuvres. Mission Director George Hale pleaded silently: “Get it down, Neil. Get it down.” The seconds ticked away. “Forward, drifting right,” Aldrin said. And then, with less than 20 seconds left, came the magic word: “Contact!” Armstrong spoke first: “Tranquillity base here, the Eagle has landed.” His words were heard by 600 million people – a fifth of humanity. About six and a half hours later, Eagle’s front door was opened and Armstrong backed out onto a small porch. He wore a €200,000 moon suit, a sort of thermos flask capable of stopping micrometeoroids travelling 30 times faster than a rifle bullet. He carried a backpack which weighed 49 kg and enough oxygen for a few hours. Heading down the ladder, Armstrong unveiled a €200,000 TV camera so the world could witness his first step: “That’s one small step for a man, one giant leap for mankind.” It was 3.56 am, 21 July, 1969.

Read the following passage given below and answer the questions the follow: The Great wall of China was built to link existing fortifications into a united defense system and better keep invading Mongol tribes out of china. It is the largest man-made monument ever to have been built and it is said that it is the only one visible from space. Many thousands of people must have given their lives to build this huge construction. The great wall of china is a series of towers made of stone, brick, earth, wood and other materials, generally built along an east-to- west line across the historical northern borders of china to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe. Several walls were being built as carly as the 7th century BCE, these later joined together and made bigger and stronger, are now collectively referred to as the Great wall Especially famous is the wall built (220-206 BCE) by Qin shi Huang, the first Emperor of China. Little of that wall remains. Since then, the great wall has on and off been rebuilt, maintained and enhanced, the majority of the existing wall is from the ming dynasty (1368-1644) other purposes of the Great wall have included border controls, allowing the imposition of duties on goods transported along the silk road, regulation or encouragement of trade and the control of immigration and emigration. Furthermore, the defensive characteristics of the Great Wall were enhanced by the construction of watch towers, troop barracks, gharrison stations, signaling capabilities through the means of smoke or fire and the fact that the path of the Great wall also served as a transportation corridor. The Great wall stretches from Dandong in the cast to Lop Lake in the west, along an are that roughly delineates the southern edge of Inner Mongolia. A comprehensive archaeological survey, using advanced technologies, has concluded that the Ming walls measure 8,850 km. This is made up of 6,259 km sections of actual wall, 359 km of trenches and 2,232 km of natural defensiove barriers such as hills and rivers. Another archaeological survey found that the entire wall with all of its branches measures out to be 21,196km. King Zheng of Qin conquered the last of his opponents and unified china as the First Emperor of the Qin Dynasty Qin shi Huang in 221 BCE. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of some sections of the walls, however, he ordered building of new walls to connect the remaining fortifications along the empire's northern frontier. Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while earth was used for construction in the plains. The Great wall concept was revived under the Ming dynasty in the 14th century, to gain a clear upper Hand over the Mongolian tribes. 1.1 On the basis of your reading of the above passage make notes on it, using headings and subheadings. Use recognizable abbreviations (Wherever necessary, minimum four) and a format you consider suitable. Also supply an appropriate title to it. 1.2 Write a summary of the passage in about 50 words.
