- Read the passage and answer the questions A and B.My brothers, I stand before you today with a heart overflowing with grief. You are fully aware of the events that are going on and understand their import. We have been trying to do our best to cope with the situation. And yet, unfortunately, the streets of Dhaka, Chattagram, Khulna, Rajshahi and Rangpur are awash with the blood of our brothers. The people of Bengal now want to be free, the people of Bengal now want to live, and the people of Bengal now want their rights. What have we done that was wrong? After the elections, the people of Bangladesh voted as one for me, for the Awami LeaguE- We were to sit in the National Assembly, draft a constitution for ourselves there, and build our country; the people of this land would thereby get economic, political, and cultural freedom. But it is with regret that I have to report to you today that we have passed through twenty- three tragic years; Bengal's history of those years is full of stories of torture inflicted on our people, of blood shed by them repeatedly. Twenty-three years of a history of men and women in agony! The history of Bengal is the history of a people who have repeatedly made their highways red with their blood. We shed blood in 1952; even though we were the victors in the elections of 1954 we could not form a government then. In 1958 Ayub Khan declared Martial Law to enslave us for the next ten years. In 1966 when we launched the six point movement our boys were shot dead on 7 JunE- When after the movement of 1969 Ayub Khan fell from power and Yahya Khan assumed the reins of the government he declared that he would give us a constitution and restore democracy; we listened to him then. A lot has happened since and elections have taken placE- I've met President Yahya Khan. I've made a request to him not only on behalf of Bengal but also as the leader of the party which has the majority in Pakistan; I said to him : "You must hold the session of the National Assembly on 15 February." But he did not listen to mE- He listened to Mr. Bhutto instead. At first he said that the meeting would take place in the first week of March. We said, "Fine, we will be taking our seats in the Assembly then." I said we will carry out our discussions in the Assembly. I went so far as to say that if anyone came up with an offer that was just, even though we were in the majority we would agree to that offer.

- Read the passage and answer the questions A and B.We set out on the evening of July 21ª. Food was scarce in the village so Abdul packed a suitcase with two loaves and some tea and tins of milk, cheese and jam. We travelled Intermediate class in a cross-country train not uncomfortably crowded, through a country of shadowy loveliness. It was a moonlit night of broken soft clouds; the land was mostly under water, with paddy and coco-palms growing from it, and a few raised cart-tracks and groups of cottages islanded among clumps of bushes, all reflected among shadows. Here and there was the red glow of a cooking-fire or the lantern of a fisherman's boat in open water. At dawn we reached Sonaimuri, a small canal-side station among wide fields, from there we had eight more miles by country boat, some of it along the canal, some of it across the flooded paddy fields. I was looking forward to that tranquil water-journey in the early morning, and tranquil it must have been, for I fell instantly asleep and knew no more till we reached the landing-ghat at Khorshed's house, in a blaze of sunlight. It turned out that his letter saying that he was bringing me was still on its way, but they rallied to the crisis and gathered round to make me welcome, though as none of them spoke any English they could only stare and laugh and offer me coconut juicE-Khorshed set me up a camp, a wooden bed, chair and table in a thatched bamboo outhousE- It was a lovely spot among bamboo and coco-palms, facing a tank where fireflies wove intricate dances at night. He put his own bed beside it for protection, and there I stayed, holding permanent court from dawn to bedtimE- Within village memory- and that went back for some two centuries, I was the first European to go there: it was too remote even for a District Commissioner to pass through. Also since I was a woman, the women could come (at different times from the men) to look at me without losing their characters. People kept coming and coming: only the rains and the fact that few of them were rich enough to have boats prevented them from coming from ten miles round. When he saw that they would not stop coming, Khorshed fixed some curtains round the bed so that I could crawl behind them when I was tired of being looked at, like a zoo animal into its sleeping hut. Even then the little hut would fill up with women and children. Children followed when I went out, and when Khorshed remonstrated a small boy pleaded, "Don't send us away! After she's gone not even a strange bird will come to the villagE-" I stood up to being the celebrity for the two days we had planned, but it was enough.

- Read the passage and answer the questions A and B.One of the sources of water in our country is the rivers. Rivers are everywhere in our life, literature, economy and culturE- But are the rivers in good shape? Unfortunately, they are not. A few are already dead and several are going through the pangs of death. The river Buriganga is an example of a dying river. A report published in the Daily Sun describes what has happened to the river Buriganga and why. Its water is polluted and a perpetual stench fills the air around it. But that is not what it was like beforE- The report says that the river had a glorious past. Once, it was a tributary of the mighty Ganges and flowed into the Bay of Bengal through the river Dhaleshwari. Gradually, it lost its link with the Ganges and got the name Buriganga. The Mughals marvelled at the tide level of the Buriganga and founded their capital Jahangirnagar on its banks in 1610. The river supplied drinking water and supported trade and commercE- Jahangirnagar was renamed Dhaka which grew into a heavily populated city with a chronic shortage of spacE- The city paid back the bounty of the river by sucking life out of it. According to newspaper report, Buriganga is dying because of pollution. Huge quantities of toxic chemicals and wastes from mills and factories, hospitals and clinics and households and other establishments are dumped into the river every day. The city of Dhaka discharges about 4500 tons of solid waste every day and most of it is directly released into the Buriganga. According to the Department of the Environment (DoE), 20,000 tons of tannery waste, including some highly toxic materials, are released into the river every day. Experts identified nine industrial areas in and around the capital city as the primary sources of river pollution: Tongi, Tejgaon, Hazaribagh, Tarabo, Narayanganj, Savar, Gazipur, Dhaka Export Processing Zone and Ghorashal.
- Read the passage and answer the questions A and B.Education aims to bring about positive changes in our behavior. It helps us try to change our lives as well as the society we live in.

- Read the passage and answer the questions A and B.Kuakata, locally known as Sagar Kannya (Daughter of the Sea) is a rare scenic spot located on the southernmost tip of Bangladesh. Kuakata in Latachapli union under Kalapara Police Station of Patuakhali district is about 30 km in length and 6 km in breadth. It is 70 km from Patuakhali district headquarters and 320 km from Dhaka. An excellent combination of the picturesque natural beauty, sandy beaches, blue sky and the shimmering expanse of water of the Bay of Bengal and the evergreen forest makes Kuakata a much sought after tourist destination. The name Kuakata takes its origin from the story of a 'Kua' or well dug on the sea shore by the early Rakhaine settlers for collecting drinking water. The Rakhaines had landed on Kuakata coast after being expelled from Arakan by the Mughals. Following the first well, it became a tradition to dig wells in the neighborhood of Rakhaine homesteads for fresh water supply. Kuakata is one of the unique spots which allows a visitor to watch both the sunrise and the sunset from the beach. That perhaps makes Kuakata one of the world's most attractive beaches. The long and wide beach at Kuakata has a typical natural setting. This sandy beach slopes gently into the Bay and bathing there is as pleasant as is swimming or diving. Kuakata is truly a virgin beach and a sanctuary for migratory winter birds. Fishing boats plying in the Bay of Bengal with colourful sails, surfing waves and the lines of coconut trees add to the vibrant colours of Kuakata. The indigenous culture of the Rakhaine community and hundred year old Buddhist temples indicate the age - old tradition and cultural heritage of this area. Kuakata is also a holy land for the Hindus and Buddhists. Each year thousands of devotees come here to attend the festivals Rash Purnima and Maghi Purnima. On these two days, pilgrims take holy bath and enjoy going to the traditional fairs.
