Read the passage given below : All of Earth’s oceans share one thing in common: plastic pollution. Discarded plastic bags, cups, and bottles make their way into the sea. Today, it seems that no part of the ocean is safe from plastic trash. In recent years, oceanographers have searched in vain for a pristine marine environment. They have found plastic everywhere they have looked. “It is a common global problem, we can’t point to a single habitat or location with no plastic.” Plastic harms wildlife and introduces dangerous chemicals into marine ecosystems - communities of organisms interacting with their surroundings. Once plastic enters the environment, it lasts a long time. Scientists are working to prevent plastic pollution from entering the sea. When people litter, or when trash is not properly disposed of, things like plastic bags, bottles, straws, foam beverage cups get carried to the sea by winds and waterways. About 80 percent of ocean plastic originates on land. The rest comes from marine industries such as shipping and fishing. In 2015, engineer Jenna Jambeck at the University of Georgia and other researchers calculated that at least 8 million tons of plastic trash is swept into the ocean from coasts every year. That’s the equivalent of a full garbage truck of plastic being dumped into the sea every minute. If current trends in plastic production and disposal continue, that figure will double by 2025. A report published by the World Economic Forum last year predicts that by 2050, ocean plastic will outweigh all the fish in the sea. In today’s world, plastic is everywhere Based on your understanding of the passage, answer ANY EIGHT questions from the nine given below. How is microplastic formed? Why is plastic compared to a sponge? What is the biggest impact of plastic pollution on sea life? How are scientists trying to reduce plastic pollutants? How does plastic waste enter the oceans? How is it true to say that plastic is everywhere in today's world? Which property of plastic makes it a problems pollutant? What has scientist Jambeck suggested for having cleaner and healthier oceans? Pick out the words/phrases from the passage which are similar in meaning to the following : rubbish/junk (as a noun) (para 3) shaped/formed (para 5)

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.
