Q1. Option 3
Syndicalism is a type of economic system proposed as a replacement for capitalism and an alternative to state socialism, which uses Confederations of collectivized trade unions or industrial unions. It is a form of socialist economic corporatism that advocates interest aggregation of multiple non-competitive categorised units to negotiate and manage an economy. For adherents, labour unions are the potential means of both overcoming economic aristocracy and running society fairly in the interest of the majority, through union democracy. Industry in a syndicalist system would be run through cooperative confederations and mutual aid.
Q2. Option 1
The Grand Canyon is a steep-sided canyon carved by the Colorado River in the United States in the state of Arizona. It is contained within and managed by Grand Canyon National Park, the Hualapai Tribal Nation, and the Havasupai Tribe. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area. A number of processes combined to create the views that we see in today’s Grand Canyon. The most powerful force to have an impact on the Grand Canyon is erosion, primarily by water (and ice) and second by wind. Other forces that contributed to the Canyon’s formation are the course of the Colorado River itself, volcanism, continental drift and slight variations in the earth’s orbit which in turn causes variations in seasons and climate.
Q3. Option 2
If the Earth didn’t rotate, winds would travel either north or south due to differences in temperature and pressure at different latitudes. But since the Earth does rotate, the Coriolis force deflects these winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The Coriolis Effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect. Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time, such as largescale movement of air in the atmosphere or water in the ocean. Such motions are constrained by the surface of the earth, so only the horizontal component of the Coriolis force is generally important. This force causes moving objects on the surface of the Earth to be deflected in a clockwise sense (with respect to the direction of travel) in the northern hemisphere, and in an anti-clockwise sense in the southern hemisphere.
Q4. Option 2
Chilka Lake is a brackish water lagoon, spread over the Puri, Khurda and Ganjam districts of Orissa state on the east coast of India, at the mouth of the Daya River, flowing into the Bay of Bengal, covering an area of over 1,100 sq. km. It is the largest coastal lagoon in India and the second largest lagoon in the World. It is the largest wintering ground for migratory birds on the Indian sub-continent.
Q5. Option 3

Q6. Option 3
Colgong (also called Kahalgaon) is a city and a municipality in Bhagalpur district in the state of Bihar.Close to Kahalgaon are the remains of the great Vikramshila University, which was famous as a centre of advanced learning across the world in the ancient times. Farakka Barrage is a barrage across the Ganges River, located in the Indian state of West Bengal, roughly 16.5 kilometres from the border with Bangladesh near Chapai Nawabganj District. Ramagundam is a town in the Karimnagar district of northern Andhra Pradesh, known as town of energy. Gandhar is one of the villages in Vagra Taluk, Bharuch district, Gujarat State of India.
Q7. Option 4
Arunachal Pradesh has population density of 10 in the 1991 Census. It stood last among all the states and Union territories of India. It retained its rank even in the 2001 Census with a population density of 13 and 2011 census with a population density of 17.
Q8. Option 2
The Pacific Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes. It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt. About 90% of the world’s earthquakes and 81% of the world’s largest earthquakes occur along the Ring of Fire. The next most seismic region (5–6% of earthquakes and 17% of the world’s largest earthquakes) is the belt which extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. The Mid-Atlantic Ridge is the third most prominent earthquake belt.
Q9. Option 3
Savanna formations find a favorable growth in form of a hot sub-humid tropical climate, a dry season and a rainy season, with an average annual temperature between 22 °C and 27 °C. A savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome. Not enough rain falls on a savanna to support forests. Savannas are also known as tropical grasslands. They are found in a wide band on either side of the equator on the edges of tropical rainforests. Savannas have warm temperature year round. There are actually two very different seasons in a savanna; a very long dry season (winter), and a very wet season (summer).
In economics, a multiplier is a factor of proportionality that measures how much an endogenous variable changes in response to a change in some exogenous variable. For example, suppose a one-unit change in some variable x causes another variable y to change by M units. Then the multiplier is M. In monetary macroeconomics and banking, the money multiplier measures how much the money supply increases in response to a change in the monetary base. The multiplier may vary across countries, and will also vary depending on what measures of money are considered. For example, consider M2 as a measure of the U.S. money supply, and M0 as a measure of the U.S. monetary base. If a $1 increase in M0 by the Federal Reserve causes M2 to increase by $10, then the money multiplier is 10.
Q11. Option 1
Instruments (certificates) issued by the ultimate borrower are called primary securities. Instruments issued by intermediaries on behalf of the ultimate borrower are called indirect securities. The market for instruments (also called securities) issued for the first time, is called the primary market. Primary security is the asset created out of the credit facility extended to the borrower and / or which are directly associated with the business / project of the borrower for which the credit facility has been extended.
Q12. Option 2
The refractive index of many materials (such as glass) varies with the wavelength or colour of the light used, a phenomenon known as dispersion. This causes light of different colours to be refracted differently and to leave the prism at different angles, creating an effect similar to a rainbow. In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency, or alternatively when the group velocity depends on the frequency. Media having such a property are termed dispersive media. Dispersion is sometimes called chromatic dispersion to emphasize its wavelength dependent nature, or group-velocity dispersion (GVD) to emphasize the role of the group.
Q13. Option 4
Exobiology is the branch of science that deals with the possibility and likely nature of life on other planets or in space. The primary goal of exobiological research is to reach a better understanding of the processes leading to the origin, evolution and distribution of life on Earth or elsewhere in the universe. Exobiological activities include comparison of the overall pattern of chemical evolution of potential precursors of life, in the interstellar medium, and on the planets and small bodies of our solar system, tracing the history of life on Earth back to its roots, deciphering the environments of the planets in our solar system and of their satellites
Although fat is a common way of storing energy, in vertebrates such as humans the fatty acids in these stores cannot be converted to glucose through gluconeogenesis as these organisms cannot convert acetyl-CoA into pyruvate; plants do, but animals do not, have the necessary enzymatic machinery. As a result, after long-term starvation, vertebrates need to produce ketone bodies from fatty acids to replace glucose in tissues such as the brain that cannot metabolize fatty acids. In other organisms such as plants and bacteria, this metabolic problem is solved using the glyoxylate cycle, which bypasses the decarboxylation step in the citric acid cycle and allows the transformation of acetyl-CoA to oxaloacetate, where it can be used for the production of glucose.
A clone is a colony of cells having similar genetic constitutions. A clone is a group of identical cells that share a common ancestry, meaning they are derived from the same mother cell A somewhat similar concept is that of clonal colony (also called a genet), wherein the cells (usually unicellular) also share a common ancestry, but which also requires the products of clonal expansion to reside at “one place”, or in close proximity. A clonal colony would be well exemplified by a bacterial culture colony, or the bacterial films that are more likely to be found in vivo (e.g., in infected multicellular hosts).
