                                   Answer»  28 .A picture that has shocked the whole world is the picture of Aylan. It has become a symbol of the problems of refugees. It is not only a picture of the dead body of a child but it is the picture of selfishness. Today refugees are facing serious problems in Europe, Asia, Middle East and Central Asia. The Muslim communities of Kashmir, Burma and Palestine are destroyed. Now millions of the Muslims of Iraq, Syria and Yemen are trying to enter in Europe and other countries. They are being cruelly treated by the police and army on the borders. 27.The Indian Rebellion of 1857 had diverse political, economic, military, religious and social causes. The spark that led to a mutiny in several sepoy companies was the issue of new gunpowder cartridges for the Enfield rifle in February, 1857. A rumour was spread that the cartridges were made from cow and pig fat. Many Indians felt that the Company was asking for heavy tax from the locals. This included an increase in the taxation on land. This seems to have been a very important reason for the spread of the rebellion, keeping in view the speed at which the conflagration ignited in many villages in northern India where farmers rushed to get back their unfairly grabbed title deeds. The resumption of tax free land and confiscation of jagirs (the grant or right to locally control land revenue) caused discontent among the jagirdars and zamindars. Dalhousie had also appointed Inam Commission with powers to confiscate land.[8]Several years before the sepoys' mutiny,Lord William Bentinckhad attacked several jagirs in western Bengal. He also resumed the practice of tax free lands in some areas. These changes caused widespread resentment not only among the landed aristocracy but also caused great havoc to a larger section of the middle-class people. Lands were confiscated from the landlords and auctioned. Rich people like the merchants and moneylenders were therefore able to speculate in British land sales and drive out the most vulnerable peasant farmers.  |

                                   Answer»  8The Kamandaka Nitisara was written in the time of Chandragupta II by Sikhara, Prime Minister of Chandragupta II. It is equivalent to Kautilya' s Arthasashtra. It gives us idea of polity and administration of the Guptas. The Devichandraguptam is a political drama attributed to Vishakhadatta, author of Mudrarakshas. It tells us about Ramagupta's defeat by a Saka ruler, murder of the Saka ruler as well as of Ramagupta by Chandragupta II, his accession to the throne and his marriage to Dhruvadevi. The Mudrarakshas of Vishakhdatta is another useful source. It gives an account of establishment of the Mauryan dynasty by Chandragupta Maurya and Kautilya. It throws light on the religion of the king and the religious condition of the people in the Gupta period. The Kaumudi Mahotsava is a drama of five Acts. It gives political condition of Magadha of that time and also throws considerable light on the origin and the rise of Gupta dynasty. It has enabled scholars to solve many riddles of the early Gupta history. Puranas occupy a very important place as a religious source. They are 18 in number but only the Vayu Purana, Brahmanda Purana, Matysa Purana, Vishnu Purana and Bhagvat Puranas give a full account of the Gupta empire, its various provinces and their boundaries. The Dharmashastras also give us a lot of useful information of the Gupta period. Inscriptions are also helpful in writing the history of the Gupta period. its about 2 marks  |

Mohen-jo Daro.Mohenjo-Daro(mound of dead) Kalibangan. ... Dholovira. ... Lothal. ... The Rig-Vedic society was a free society. The Aryans evidently preferred male child to female child. However, females were as free as their male counterparts. Education was equally open for boys and girls. Girls studied the Veda and fine arts. Women never observed purdha in the Vedic period. They enjoyed freedom in selecting their mates. But divorce was not permissible to them. In the family, they enjoyed complete freedom and were treated as Ardhanginis. In domestic life women were considered to be supreme and enjoyed freedom. Home was the place of production. Spinning and weaving of clothes was done at home. Women helped their husbands in agricultural pursuits also. Husband used to consult his wife on financial matters. Unmarried daughters had share in their fathers’ property. Daughter had full legal rights in the property of her father in the absence of any son. Mother’s property, after her death, was equally divided among sons and unmarried daughters. However, married women had no share in father’s property. As a wife, a woman had no direct share in her husband’s property. A widowed mother had some rights. The woman was regarded as having an equally important share in the social and religious life because a man without woman was considered as an inadequate person. She regularly participated in religious ceremonies with her husband. There were many scholars who composed hymns of Rig Veda. Lopamudra, Gargi and Maitreye were the pioneers among them. Lopamudra, the wife of Agasti rishi, composed two verses of Rig Veda. It may be concluded that during vedic period the status of women was not unequal to that of men. Women got the same education as men and participated in the philosophical debates.  |

|

(a) Family planning measures were adopted, leading to decline in the birth rate. (b) Awareness about advantages of small family came to be recognised.(c) There was a growth of nuclear families occured which adopted the small family norm.(d) Promotion of family planning programme by the government. (ii) Discuss the major components of population growth. Answer The major components of population growth are birth rates, death rates and migration. The natural increase of population is the difference between birth rates and death rates. Birth RateBirth rate is the number of live births per thousand person in a year. It is a major component of growth, because in India birth rates have always been higher than death rates. Death RateDeath rate is the number of deaths per thousand persons in a year. The main cause of the rate of growth of the Indianpopulation has been the rapid decline in death rates. Migration Migration is the movement of people across regions and territories. Migration can be internal (within the country) or international (between the countries). Internal migration does not change the size of the population, but influences the distribution of population within the nation.  |

                                   Answer»  The maincauses of total clearance are agriculture and in drier areas, fuel wood collection. The maincauseof forest degradation is logging. Mining, industrial development and large dams also have a serious impact. Rainforestsare often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and producing oxygen, upon which all animals depend for survival.Rainforestsalso stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet.  |

                                   Answer»  The world’s oldest civilization grew around the Indus and the Ganges and is still thriving. But not for long. Post-independence, due importance was given to harnessing the power of water by way of controlling and storing of water through large Dams. That was the need of the hour. However, our cities and towns have subsequently grown without planning for water need vs water availability. In 1951, the per capita water availability was about 5177 m3. This has now reduced to about 1545 m3 in 2011 Reasons behind water scarcity in India The water scarcity is mostly man made due to excess population growth and mismanagement of water resources. Some of the major reasons for water scarcity are: Inefficient use of water for agriculture. India is among the top growers of agricultural produce in the world and therefore the consumption of water for irrigation is amongst the highest. Traditional techniques of irrigation causes maximum water loss due to evaporation, drainage, percolation, water conveyance, and excess use of groundwater. As more areas come under traditional irrigation techniques, the stress for water available for other purposes will continue. The solution lies in extensive use of micro-irrigation techniques such as drip and sprinkler irrigation. Reduction in traditional water recharging areas. Rapid construction is ignoring traditional water bodies that have also acted as ground water recharging mechanism. We need to urgently revive traditional aquifers while implementing new ones. Sewage and wastewater drainage into traditional water bodies. Government intervention at the source is urgently required if this problem is to be tackled. Release of chemicals and effluents into rivers, streams and ponds. Strict monitoring and implementation of laws by the government, NGOs and social activists is required. Lack of on-time de-silting operations in large water bodies that can enhance water storage capacity during monsoon. It is surprising that the governments at state levels has not taken this up on priority as an annual practice. This act alone can significantly add to the water storage levels. Lack of efficient water management and distribution of water between urban consumers, the agriculture sector and industry. The government needs to enhance its investment in technology and include all stakeholders at the planning level to ensure optimization of existing resources. Urban nightmare The problem has been compounded with increased concretization due to urban development that has choked ground water resources. Water is neither being recharged nor stored in ways that optimizes its use while retaining the natural ingredients of water. In addition, the entry of sewage and industrial waste into water bodies is severely shrinking the availability of potable water. Marine life is mostly lost in these areas already. This is the genesis of a very serious emerging crisis. If we do not understand the source of the problem we will never be able to find sustainable solutions.  |

                                   Answer»  There are a good number of reasons why the British were able to do so, and in fact rule over India effectively for over a century. Disunity among Indian princely states. India was more a collection of warring princely states, at loggerheads with each other. The British successfully used this to play off one state against another. Add to it there was no dearth of people willing to betray the kingdom for a few pieces of silver. Robert Clive succeeded at Plassey, because Mir Jaffar was willing to betray his master Siraj-Ud-Daulah in lie of being the Nawab. Mir Jaffar himself was betrayed by Mir Qasim later on.Tipu Sultan one of the most redoubtable fighters against the British rule, was finally defeated, as the Marathas, King of Mysore, Nizam of Hyderabad all joined hands with the British. Superiority over other colonial powers. The other colonial powers in India competing for the share of resources were France,Portugal,Denmark, Holland. Of the 4, Denmark and Holland could never really be serious competitors to the British, they had their own trading posts, scattered around, but were never a serious threat. Portugal focussed primarily on the Western coast, Goa, parts of Kerala, Karnataka, and this left the British with vast swathes of unoccupied territory. That left France as the major contender to Britian in the race for colonialism. The British Army was more well equipped, more professional, more disciplined compared to the French army, suffering from indiscipline and corruption. This made the British win key battles all over the East Coast, as they effectively grabbed control. Doctrine of Lapse.One of the most effective tactics, the British used to take over most of India. Instead of waging an all out war against some of the princely states, they signed a treaty with them, where in if the ruling king died without a heir, the East India company could take over that. And that is how Satara became one of the first states to end up under British rule. And that was also the main reason for the conflict in Jhansi.  |

| 
                                   Answer»  Factors influencing the climate of India:1) LATITUDE - Due to the curvature of the Earth, the amount of solar energy received is different according to the latitudes. 2) ALTITUDE - As we go higher, temperature generally decreases (From equator to poles) as the atmosphere becomes less dense. 3) PRESSURE AND WIND SYSTEM - They depend on the latitude and altitude of a place, thus influencing the rainfall patterns. 4) DISTANCE FROM SEA - The sea has a moderating effect on the climate. As distance from sea increases, this effect decreases and places experience extreme weather conditions (continentality). 5) OCEAN CURRENTS - They affect the climate of the coastal areas with the onshore winds.  |

                                   Answer»  The Himalayan range consists of 3 parallel sub ranges. These ranges are : Himadri(Greater Himalayas) It is the most continuous range. It consists of loftiest peaks with an average height of 6,000 metres. It contains prominent peaks like Mount Everest, Kanchenjunga, Nanga Parbat and many more. This range remains snow covered throughout the year, resulting in the formation of glaciers and some perennial rivers. The core of this part of the himalayas is composed of granite. Himachal(Lesser Himalayas) It lies to the south of Himadri and forms the most rugged mountain system. Average height is between 3,700 to 4,500 metres. It has some famous valleys like Kullu, Kangra and Kashmir. This range is famous for it’s hill stations. The Pir Panjal range forms the longest and the most important range. The Dhaula Dhar and the Mahabharat ranges are also prominent ones. Shiwalik(Outer Himalayas) It is the outermost range of Himalayas. The altitude in this range varies from 900 to 1000m. These ranges are composed of loose river deposits brought down by rivers from the main Himalayan ranges located for north. The longitudinal valley lying between lesser himalaya and shiwaliks are known asduns. Dehra Dun, Kotli Dun and Patli Dun are some of the well known duns.  |
