General Instructions:

Q1 and Q2 to be done on an A-4 size sheet.

Do Q3 to Q7 in your English notebook.

Attempt all the questions and do them neatly.

Q1. Design a poster on the topic ‘India of my Dreams’. You may add some relevant slogans also. (Refer to the chapter ‘Glimpses of India’) Q2. On the basis of your reading of the chapter 'The Necklace’, create a comic strip on an A-4 size sheet elaborating its theme, ‘Contentment in life is the key to true happiness’. Q3. Read lesson no 1,2 and 7 from the book 'Footprints Without Feet' and attempt the exercises given at the back in your notebook.

Q4. Read the passage given below.

1. Sacred trees form an important part of the ecological heritage of India. Most temples, towns, villages-and sometimes even Muslim dargahs-are associated with trees. Some plants are sacred to the individual deity; others are sacred to the place. Several plants have been worshipped in India from time immemorial. Wherever the tulsi grows-from the Indo- Gangetic plains to the shores of the Indian Ocean at Kanyakumari-it occupies a position of pride in the central courtyard of the house, tended to, carefully, by the housewife.

2. Apart from the elaborate myths connecting it to krishna, the tulsi plant has several medicinal properties.

3. To protect and revere this plant with so many medicinal properties, it was designated as sacred, a fitting tribute to its role in providing invaluable healthcare. The worship of plants is an ancient phenomenon in India. It is probably the oldest form of worship. The association of a single tree with a sacred sthala or sthana is reflected in the chaitya vriksha and sthala vriksha or literature and society.

4. When people turned to food production, the Mother Goddess or the Earth Mother became the chief deity. Fertility, creation, and the world of plants and animals became her blessings to her devotees. The worship of the tree was the adoration of her creative abilities, symbolising fertility so essential or the survival of the early people. Spirits-good or bad-were believed to reside in trees. If the trees were worshipped, then the resident spirits were pleased. As sacred forests were replaced by agriculture, a single tree was left and was designated as 'sacred' tree.

5. The earliest temples were little more than images placed under trees. Later, the tree and the image were enclosed by a fence made of wood, followed even by stone. Numerous references are made in literature to trees as abodes of gods.

On the basis of your understanding of the passage, answer the following:

Q5. Read the passage given below.

India is one of the fastest growing economies in 2020. Poverty is on the decline with close to 44 Indians escaping extreme poverty every minute, according to the World Poverty Clock.

According to the Brookings report, today India has 73 million people living in extreme poverty which makes up 5.5% of its total population.

Two-thirds of people in India live in poverty. 68.8% of the Indian population live on less than $2 a day. Over 30% even have less than $1.25 per day and such people are considered extremely poor.

More than 800 million people in India are considered poor. Most of them live in the countryside and

Page 4 of 20

keep afloat with odd jobs. The lack of employment which provides a liveable wage in rural areas is driving many Indians into rapidly growing metropolitan cities, such as Mumbai, Delhi, Kolkata and Bengaluru.

In 2019, the Indian government stated that 6.7% of its population is below its official poverty limit. According to Oxfam, India's top 1% of the population now holds 73% of the wealth while 670 million citizens, comprising the country's poorest half, saw their wealth rise by just 1%. As per the Tendulkar Poverty Line, poverty reduced from 14.9 per cent in 2011 to 7.0 per cent in 2017- the fastest pace the country has seen yet. So, 2020 is extremely challenging year not only for government and business, but also for those who are on the borderline of poverty. Fiscal, monetary, and administrative policies have to be designed in a way that provides a safety for those living at the brink of poverty. Lifting people out of poverty ought to be on top of the government's priority.

Q 6. Read the passage given below.

The choices we make on a daily basis—wearing a seatbelt, lifting heavy objects correctly or purposely staying out of any dangerous situation—can either ensure our safety or bring about potentially harmful circumstances.

You and I need to decide that we are going to get our lives in order. Exercising self-control, self-discipline and establishing boundaries and borders in our lives are some of the most important things we can do. A life without discipline is one that is filled with carelessness.

We can think it is kind of exciting to live life on the edge. We like the image of “Yeah! That is me! Living on the edge! Woo-hoo!” It has become a popular way to look at life. But if you see, even highways have lines, which provide margins for our safety while we are driving. If we go over one side, we will go into the ditch. If we cross over the line in the middle, we could get killed. And we like those lines because they help to keep us safe. Sometimes we do not even realize how lines help to keep us safe.

I am not proud of this, but for the first 20 years of my life at work, I ignored my limits. I felt horrible, physically, most of the time. I used to tell myself “I know I have limits and that I’ve reached them, but I’m going to ignore them and see if or how long I can get by with it.” I ran to doctors, trying to make myself feel better through pills, vitamins, natural stuff, and anything I could get my hands on. Some of the doctors would tell me, “It’s just stress.” That just made me mad. I thought stress meant you do not like what you do or cannot handle life, and I love what I do. But I kept pushing myself, traveling, doing speaking engagements and so on— simply exhausting myself.

Finally, I understood I was living an unsustainable life and needed to make some changes in my outlook and lifestyle.

You and I do not have to be like everyone else or keep up with anyone else. Each of us needs to be exactly the way we are, and we do not have to apologize for it. We are not all alike, and we need to find a comfort zone in which we can enjoy our lives instead of making ourselves sick with an overload of stress and pressure.

On the basis of understanding of the passage, answer ANY TEN questions from the twelve that follow.

Q1) Which of the characteristics are apt about the writer in the following context: “I know I have limits and that I’ve reached them, but I’m going to ignore them and see if or how long I can get by with it.”?

CLASS 10 SSC ASSIGNMENT 1-SOURCE BASED QUESTIONS TO BE DONE IN HISTORY REGISTER HISTORY 1) Read the source given below and answer the questions that follows: C. R. Das and Motilal Nehru formed the Swaraj Party within the Congress to argue for a return to council politics. But younger leaders like Jawaharlal Nehru and Subhas Chandra Bose pressed for more radical mass agitation and for full independence. In such a situation of internal debate and dissension two factors again shaped Indian policies towards the late 1920s. The first was the effect of the worldwide economic depression. Agricultural prices began to fall from 1926 and collapsed after 1930. As the demand for agricultural goods fell and exports declined, peasants found it difficult to sell their harvests and pay their revenue. By 1930, the countryside was in turmoil. Against this background the new Tory government in Britain constituted a Statutory Commission under Sir John Simon. Set up in response to the nationalist movement, the commission was to look into the functioning of the constitutional system in India and suggest changes. The problem was that the commission did not have a single Indian member. They were all British. When the Simon Commission arrived in India in 1928. It was greeted with the slogan ‘Go back Simon’. All parties, including the Congress and the Muslim League, participated in the demonstrations. In an effort to win them over, the viceroy, Lord Irwin, announced in October 1929 a vague offer of dominion status for India in an unspecified future and a Round Table Conference to discuss a future constitution. This did not satisfy the Congress leaders. The radicals within the Congress, led by Nehru and Bose, became more assertive. The liberals and moderates, who were proposing a constitutional system within the framework of British dominion, gradually lost their influence. In December1929, under the presidency of Nehru, the Lahore Congress formalised the demand of ‘Purna Swaraj’ or full independence for India. It was declared that 26th January 1930 would be celebrated as the Independence Day when people were to take a pledge to struggle for complete independence. But the celebrations attracted very little attention. So, Mahatma Gandhi had to find a way to relate this abstract idea of freedom to more concrete issues of everyday life. Answer the following MCQs by choosing the appropriate option 1. The Simon Commission was boycotted because: a. There was no British Member in the Commission. b. It demanded separate electorates for Hindus and Muslims. c. There was no Indian Member in the Commission. d. It favoured the Muslims over the Hindus.

Page 15 of 20

2. Who formed the ‘Swaraj Party’ within the congress? a. Jawaharlal Nehru & Motilal Nehru b. Abdul Ghaffar Khan & Mahatma Gandhi c. Jawaharlal Nehru & Subash Chandra Bose d. C. R. Das & Motilal Nehru 3. In which of the following Indian National Congress sessions was the demand of ‘Purna Swaraj’ formalized in December 1929? a. Madras session b. Lahore session c. Calcutta session d. Nagpur session. 4. Why was the Simon Commission set up by the British? a. It was to manage all civil administrations in India. b. It came for financial and business issues. c. It came to make peace on various issues. d.The commission was to look into the functioning of the constitutional system in India and suggest changes. POLITICAL SCIENCE 2) Read the source given below and answer the questions that follows: Power may also be shared among different social groups such as the religious and linguistic groups. “Community Government” in Belgium is a good example of this arrangement. In some countries there are constitutional and legal arrangements whereby socially weaker sections and women are represented in the legislatures and administration. Last year, we studied the system of ‘reserved constituencies’ in assemblies and the parliament of our country. This type of arrangement is meant to give space in the government and administration to diverse social groups who otherwise would feel alienated from the government. This method is used to give minority communities a fair share in power. Power sharing arrangements can also be seen in the way political parties, pressure groups and movements control or influence those in power. In a democracy, the citizens must have freedom to choose among various contenders for power. In contemporary democracies, this takes the form of competition among different parties. Such competition ensures that power does not remain in one hand. In the long run, power is shared among different political parties that represent different ideologies and social groups. Sometimes this kind of sharing can be direct, when two or more parties form an alliance to contest elections. Answer the following MCQs by choosing the appropriate option 1. Which one of the following statements about community government is true? a. Power is shared among different organs of the government. b. Power is shared among governments at different levels. c. Power is shared by different social groups. d. Power is shared by two or more political parties. 2. Power can be shared in modern democracies in the following ways: a. Among different organs of the govt. b. Among various levels c. Among different social groups d. All the above. 3. Power sharing is good because: a. It increase the conflict between social groups b. It ensures the instability of political order c. It reduces the possibility of conflict between social groups d. It leads to violence 4. Which is the prudential reason for power sharing? a. It reduces the possibility of conflict between communities and ensures the stability of political order. b. Power sharing is the very spirit of democracy c. Both the above d. None of the above. GEOGRAPHY

SOURCE BASED QUESTION 3. Read the source given below and answer the questions that follows: Resource planning is a complex process which involves: i) identification and inventory of resources across the regions of the country. This involves surveying, mapping and qualitative and quantitative estimation and measurement of the resources. ii) Evolving a planning structure endowed with appropriate technology, skill and institutional set up for implementing resource development plan. iii)

Page 16 of 20

Matching the resource development plans with overall national development plans. India has made concerted efforts for achieving the goals of resource planning right from the First Five Year Plan launched after Independence. The availability of resources is a necessary condition for the development pf any region, but mere availability of resources in the absence of corresponding changes in technology and institutions may hinder development. There are many regions in our country that are rich in resources but these are included in economically backward regions. On the contrary there are some regions which have a poor resource base but they are economically developed. The history of colonization reveals that rich resources in colonies were the main attractions for the foreign invaders. It was primarily the higher level of technological development of the colonizing countries that helped them to exploit resources of other regions and establish their supremacy over the colonies. Therefore, resources can contribute to development only when they are accompanied by appropriate technological developments and institutional changes. India has experienced all this in different phases of colonization. Therefore, in India, development, in general and resource development in particular does not only involve the availability of resources, but also the technology, quality of human resources and the historical experiences of the people. Answer the following MCQs by choosing the most appropriate option. 1) From which Five-Year Plan has India made concerted efforts for achieving the goals of resource planning? a. First Five Year Plan b. Fifth Five Year Plan c. Annual Plans d. Tenth Five Year Plan 2) Resource planning is essential for_________ existence of all forms of life. a. Ecological balance b. Sustainable c. Exploitation d. None of these 3. What was the main attraction of foreign invaders to India? a. Architecture b. Rich resources in colony c. Irrigation method d. Spices 4. Which of the following is essential for sustainable existence of all forms of life? a. Resource planning b. Resource management c. Resource extraction d. Resource generation ECONOMICS SOURCE BASED QUESTION 4. Read the source given below and answer the questions that follows: GROUNDWATER IN INDIA Recent evidence suggests that the groundwater is under serious threat of overuse in many parts of the country. About 300 districts have reported a water level decline of over 4 metres during the past 20 years. Nearly one- third of the country is overusing their groundwater reserves. In another 25 years 60 percent of the country would be doing the same if the present way of using this resource continues. Groundwater overuse is particularly found in the agriculturally prosperous regions of Punjab and Western U,P,, hard rock plateau areas of central and south India, some coastal areas and the rapidly growing urban settlements. Answer the following MCQs by choosing the most appropriate option. 1. The groundwater level in Punjab and Western UP is low:

Page 17 of 20

a. Because of irresponsible attitude of the people b. Because of draining of large tracts of land c. Overuse of water for development projects d. Because of Green Revolution 2. How urban settlements are responsible for low groundwater levels? a. People in urban areas are not responsible b. Increasing construction activity c.
