According to Einstein’s theory, light, just like any other form of matter, is affected by gravity. That is, light also “falls” in a gravitational field. Just as a comet’s trajectory is deflected by the sun when it passes nearby, a ray of starlight grazing the sun would also be deflected or bent. When we (or our camera) look at the star, we presume that the path taken by the light is straight. The effect of the bending of the light, then, is to make the star appear to be located in a slightly different position in the sky.

• The Charter Act of 1813 adopted a provision to spend one lakh rupees per annum for the spread of education in India.
• Although there was a prolonged debate pertaining to education during the course of a general discussion on the Act of 1813 in the British Parliament, yet the matter continued to generate debate for the next 20 years. Consequently, not even a single penny out of the allocated funds could be spent on education.
• The contemporary British scholars were divided into two groups on the issue of development of education in India. One group, called the Orientalists, advocated the promotion of oriental subjects through Indian languages. The other group, called the Anglicists, argued the cause of western sciences and literature in the medium of English language.
• In 1829, after assuming the office of the Governor-General of India, Lord William Bentinck, emphasized on the medium of English language in Indian education.
• In the beginning of 1835, the 10 members of the General Committee of Public Instruction were clearly divided into two equal groups.
• Five members including the Chairman of the committee Lord Macaulay were in favour of adopting English as medium of public instruction whereas the other five were in favour of oriental languages.
• The stalemate continued till 2 February 1835 when the Chairman of the committee, Lord Macaulay announced his famous Minute advocating the Anglicist point of view.
• Consequently, despite fierce opposition from all quarters, Bentinck got the resolution passed on 7 March 1835 which declared that henceforth, government funds would be utilized for the promotion of western literature and science through the medium of English language.

(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Ans: b
Exp: Sand Mining and impact on environment
Sand Mining is an activity referring to the process of the actual removal of sand from the foreshore including rivers, streams and lakes. Sand is mined from beaches and inland dunes and dredged from ocean beds and river beds. A related process is the mining of mineral sands, such as mineral deposits like diamond, gold and silver. These minerals typically occur combined with ordinary sand. The sand is dug up, the valuable minerals are separated in water by using their different density, and the remaining ordinary sand is re-deposited.
Excessive in-stream sand-and-gravel mining causes the degradation of rivers. In-stream mining lowers the stream bottom, which may lead to bank erosion. Depletion of sand in the streambed and along coastal areas causes the deepening of rivers and estuaries, and the enlargement of river mouths and coastal inlets. It may also lead to saline-water intrusion from the nearby sea. The effect of mining is compounded by the effect of sea level rise. Any volume of sand exported from streambeds and coastal areas is a loss to the system. It is also a threat to bridges, river banks and nearby structures. Sand mining also affects the adjoining groundwater system and the uses that local people make of the river.
In-stream sand mining results in the destruction of aquatic and riparian habitat through large changes in the channel morphology. Impacts include bed degradation, bed coarsening, lowered water tables near the streambed, and channel instability. These physical impacts cause degradation of riparian and aquatic biota and may lead to the undermining of bridges and other structures. Continued extraction may also cause the entire streambed to degrade to the depth of excavation. Sand mining generates extra vehicle traffic, which negatively impairs the environment. Where access roads cross riparian areas, the local environment may be impacted.
In-stream mining can have other costly effects such as many hectares of fertile streamside land are lost annually, as well as valuable timber resources and wildlife habitats in the riparian areas. Degraded stream habitats result in loss of fisheries productivity, biodiversity, and recreational potential. Severely degraded channels may lower land and aesthetic values.
Further all species require specific habitat conditions to ensure long-term survival. Native species in streams are uniquely adapted to the habitat conditions that existed before humans began large-scale alterations. These have caused major habitat disruptions that favored some species over others and caused overall declines in biological diversity and productivity. In most streams and rivers, habitat quality is strongly linked to the stability of channel bed and banks. Unstable stream channels are inhospitable to most aquatic species.
Factors that increase or decrease sediment supplies often destabilize bed and banks and result in dramatic channel readjustments. For example, human activities that accelerate stream bank erosion, such as riparian forest clearing or in-stream mining, cause stream banks to become net sources of sediment that often have severe consequences for aquatic species. Anthropogenic activities that artificially lower stream bed elevation cause bed instabilities that result in a net release of sediment in the local vicinity. Unstable sediments simplify and, therefore, degrade stream habitats for many aquatic species. Few species benefit from these effects.
The most important effects of in-stream sand mining on aquatic habitats are bed degradation and sedimentation, which can have substantial negative effects on aquatic life. The stability of sand-bed and gravel-bed streams depends on a delicate balance between stream-flow, sediment supplied from the watershed, and channel form. Mining-induced changes in sediment supply and channel form disrupt channel and habitat development processes. Furthermore, movement of unstable substrates results in downstream sedimentation of habitats. The affected distance depends on the intensity of mining, particles sizes, stream flows, and channel morphology.
The complete removal of vegetation and destruction of the soil profile destroys habitat both above and below the ground as well as within the aquatic ecosystem, resulting in the reduction in faunal populations.
Also, Channel widening shallows the streambed, producing braided flow or subsurface inter-gravel flow in riffle areas, hindering movement of fishes between pools. Channel reaches become more uniformly shallow as deep pools fill with gravel and other sediments, reducing habitat complexity, riffle-pool structure, and numbers of large predatory fishes.
Apart from it, sand mining transforms the riverbeds into large and deep pits; as a result, the groundwater table drops leaving the drinking water wells on the embankments of these rivers dry. Bed degradation from in-stream mining lowers the elevation of stream flow and the floodplain water table which in turn can eliminate water table-dependent woody vegetation in riparian areas, and decrease wetted periods in riparian wetlands. For locations close to the sea, saline water may intrude into the fresh water body.
In-stream sand mining activities will have an impact upon the river’s water quality. Impacts include increased short-term turbidity at the mining site due to resuspension of sediment, sedimentation due to stockpiling and dumping of excess mining materials and organic particulate matter, and oil spills or leakage from excavation machinery and transportation vehicles.
Increased riverbed and bank erosion increases suspended solids in the water at the excavation site and downstream.
Suspended solids may adversely affect water users and aquatic ecosystems. The impact is particularly significant if water users downstream of the site are abstracting water for domestic use. Suspended solids can significantly increase water treatment costs.
67. With reference to agricultural soils, consider the following statements:
1. A high content of organic matter in soil drastically reduces its water holding capacity.

(a) 1 and 2 only
(b) 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Ans: b
Exp: “Each 1 percent increase in soil organic matter helps soil hold 20,000 gallons more water per acre.”
• Sulphur Cycle
Sulphur cycle, circulation of sulfur in various forms through nature. Sulphur is key to protein structure and is released to the atmosphere by the burning of fossil fuels. Sulphur occurs in all living matter as a component of certain amino acids. It is abundant in the soil in proteins and, through a series of microbial transformations, ends up as sulphates usable by plants.
Sulphur-containing proteins are degraded into their constituent amino acids by the action of a variety of soil organisms. The sulphur of the amino acids is converted to hydrogen sulphide (H2S) by another series of soil microbes. In the presence of oxygen, H2S is converted to sulfur and then to sulphate by sulfur bacteria. Eventually the sulfate becomes H2S.
Hydrogen sulphide rapidly oxidizes to gases that dissolve in water to form sulphurous and sulphuric acids. These compounds contribute in large part to the "acid rain" that can kill sensitive aquatic organisms and damage marble monuments and stone buildings.
Thus cycle can be divided as:
· Sulphur Cycle in Soils
Sulphur enters the trophic cycle in terrestrial plants via root adsorption in the form of inorganic sulphates (e.g., calcium sulphate, sodium sulphate) or by direct assimilation of amino acids released in the decomposition of dead or excreted organic matter. Bacterial and fungal (Aspergillus and Neurospora) mineralization of the organic sulphhydryl in amino acids followed by oxidation results in sulphate; this adds to the sulphate pool for root adsorption.
· Sulphur Cycle in Atmosphere
Sulphur in the atmosphere comes from several different sources: decomposition and/or combustion of organic matter, combustion of fossil fuels, and ocean surfaces and volcanic eruptions. The most prevalent form of sulphur entering the atmosphere is sulphur dioxide (SO2). It, along with other atmospheric forms such as elemental sulphur and hydrogen sulphide, is oxidized to sulphur trioxide (SO3), which combines with water to form sulphuric acid (H2SO4), leading to acid rain.
Atmospheric sulphur, largely in the form of sulphuric acid, is removed by two general processes: rainout, which includes all processes within clouds that result in removal; and washout, which is the removal by precipitation below the clouds. Depending on the amount of the various sulphur compounds available to form the sulphuric acid, the degree of acidity can be strong enough to ap-proximate that of battery acid. Atmospheric inputs of sulphuric acid provide the dominant source of both hydrogen ions (H+) for cation replacement.
· Sulphur in Sediments
The sedimentary aspect of the cycle involves the precipitation of sulphur in the presence of such cations as iron (Fe) and calcium (Ca) as highly insoluble ferrous sulphide (FeS) and ferric sulphide (Fe2S3, pyrite) or relatively insoluble calcium sulphate (CaSO4).
The oxidation of sulphides in marine sediments is a key process, though poorly understood.
Salinity also Caused due to excessive irrigation in dry conditions which promotes capillary action
68. The Partnership for Action on Green Economy (PAGE), a UN mechanism to assist countries transition towards greener and more inclusive economies, emerged at

(b) The United Nations Conference on Sustainable Development 2012, Rio de Janeiro
(c) The United Nations Framework Convention on Climate Change 2015, Paris
(d) The World Sustainable Development Summit 2016, New Delhi
Ans: b
Exp: Sustainable development has been the overarching goal of the international community since the UN Conference on Environment and Development (UNCED) in 1992. Amongst numerous commitments, the Conference called upon governments to develop national strategies for sustainable development, incorporating policy measures outlined in the Rio Declaration and Agenda 21. Despite the efforts of many governments around the world to implement such strategies as well as international cooperation to support national governments, there are continuing concerns over global economic and environmental developments in many countries. These have been intensified by recent prolonged global energy, food and financial crises, and underscored by continued warnings from global scientists that society is transgressing a number of planetary boundaries or ecological limits.
With governments today seeking effective ways to lead their nations out of these related crises whilst also taking into account these planetary boundaries, green economy (in its various forms) has been proposed as a means for catalysing renewed national policy development and international cooperation and support for sustainable development. The concept has received significant international attention over the past few years as a tool to address the 2008 financial crisis as well as one of two themes for the 2012 UN Conference on Sustainable Development (Rio+20). This has resulted in a rapidly expanding literature including new publications on green economy from a variety of influential international organisations, national governments, think tanks, experts, non-government organisations and others.
Governments agreed at Rio+20 to frame the green economy as an important tool for sustainable development; one that is inclusive and can drive economic growth, employment, and poverty eradication, whilst maintaining the healthy functioning of the Earth’s ecosystems. Importantly, the outcome document also recognises that capacity building, information exchange and experience sharing will be critical for implementing green economy policies.
Recent initiatives on green economy or green growth by the United Nations Environment Program (UNEP), the UN Department of Economic and Social Affairs (UNDESA), the United Nations Conference on Trade and Development (UNCTAD), the International Labour Organisation (ILO), the World Bank, the Organisation for Economic Cooperation and Development (OECD), the Global Green Growth Institute (GGGI), the Partnership for Action on Green Economy (PAGE), the Green Growth Knowledge Platform (GGKP) the Green Economy Coalition

Many other invertebrates, vertebrates, and plants live in close association to the corals, with tight resource coupling and recycling, allowing coral reefs to have extremely high productivity and biodiversity, such that they are referred to as ‘the Tropical Rainforests of the Oceans’.
Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest.
Major Regions of Coral Reef Development
Globally, three major regions of coral reef development are generally recognized, each with a somewhat distinctive biota. These are:
(1) The Indo-Pacific – Includes most of the Indian Ocean (excluding the Red Sea), and the western Pacific.
(2) The Wider Caribbean(tropical western Atlantic) – Includes Florida, The Bahamas, Caribbean Sea proper, and coastal waters off northeastern S. America.

3. When living organisms originated, they modified the early atmosphere of the Earth.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Ans: c
Exp: The Earth’s Magnetic field has reversed every few hundred thousand years. This has been proved through Sea-Floor spreading.
When Earth was created there was no oxygen in the atmosphere. Oxygen makes up about one-fifth the volume of Earth’¬s atmosphere today and is a central element of life as we know it. But that wasn’¬t always the case. Oxygen, although always present in compounds in Earth’¬s interior, atmosphere, and oceans, did not begin to accumulate in the atmosphere as oxygen gas (O2) until well into the planet’¬s history.
Carbon dioxide, water vapor, and methane played an important role in Earth’¬s subsequent development.
By 2.7 billion years ago, a new kind of life had established itself: photosynthetic microbes called cyanobacteria, which were capable of using the Sun’¬s energy to convert carbon dioxide and water into food with oxygen gas as a waste product. They lived in shallow seas, protected from full exposure to the Sun’¬s harmful radiation.
These organisms became so abundant that by 2.4 billion years ago the free oxygen they produced began to accumulate in the atmosphere.

(a) 1, 3 and 4
(b) 2, 3, 4 and 5
(c) 2, 4 and 5
(d) 1, 2, 3 and 5
Ans: c
Exp: Conservation Agriculture is a set of soil management practices that minimize the disruption of the soil’s structure, composition and natural biodiversity.

o maintenance of permanent or semi-permanent soil cover (using either a previous crop residue or specifically growing a cover crop for this purpose);
o minimum soil disturbance through tillage (just enough to get the seed into the ground) ;
o regular crop rotations to help combat the various biotic constraints;
Conservation Agriculture also uses or promotes where possible or needed various management practices listed below:
o utilization of green manures/cover crops (GMCC’s) to produce the residue cover;
o no burning of crop residues;
o integrated disease and pest management;
o controlled/limited human and mechanical traffic over agricultural soils.
