Uttar Pradesh 2022 Previous Year GK Questions with Answers

The correct answer is A, 8 bit. A microprocessor is named after the width of its data bus, that is, the number of bits it can carry in and out in a single operation. Here there are eight data lines, so eight bits move at a time and the chip is an 8-bit microprocessor; the Intel 8085 is the classic example, with eight data lines and sixteen address lines. B is wrong because the sixteen address lines decide only how much memory the processor can reach, which is two raised to the power sixteen, or 65,536 locations, and not the name of the processor. C is wrong because 20 address lines belong to the Intel 8086 family, which could address one megabyte, and address lines again do not fix the bit size. D is wrong because a 32-bit processor would need thirty-two data lines. The rule to remember is simple: data lines give the bit size, address lines give the memory capacity.

The correct answer is D, A - 4, B - 3, C - 2, D - 1. Ramanuja taught Vishishtadvaita or qualified non dualism, in which souls and matter are real but exist as attributes of Brahman. Madhvacharya taught Dvaita, a thoroughgoing dualism in which god and the individual soul remain eternally distinct. Nimbarka taught Dvaitadvaita or bhedabheda, holding that difference and non difference are both real. Vallabhacharya taught Shuddhadvaita, pure non dualism, in which Brahman is real and untouched by maya. Option A is wrong because it gives Ramanuja Dvaitadvaita, which belongs to Nimbarka. Option B is wrong because it gives Ramanuja Dvaita and Madhvacharya Shuddhadvaita, reversing the two positions that are most often confused. Option C is wrong because it pairs the four teachers with the philosophies in the order in which the lists happen to be printed, which is the trap in every match the list question of this kind.

The correct answer is B, Karnataka. Article 168 says a State legislature consists of the Governor and either one House or two Houses. Where there are two, the upper House is the Legislative Council or Vidhan Parishad, and Karnataka is one of the few States that has kept it. Article 169 allows Parliament to create or abolish a Council if the Legislative Assembly of that State passes a resolution by a special majority, which is why the list of such States is short and changes only by law. Option A, Jharkhand, has only a Legislative Assembly; so does option C, Odisha, although proposals for a Council have been discussed there; and option D, Gujarat, also has a single House. Under Article 171 one-sixth of a Council is nominated by the Governor from persons distinguished in literature, science, art, the cooperative movement and social service, which is the link between this chapter and the State Executive.

The correct answer is D, copper and zinc. Brass takes the workability of copper and the hardness of zinc, resists corrosion and is easy to cast, which is why it is used for utensils, locks, taps, fittings and wind instruments. Option A, copper and tin, is bronze, and the brass and bronze pair is the single most frequently confused item in this chapter, so fix zinc with brass and tin with bronze. Option B, copper and nickel, is cupronickel, used in coins and in condenser tubes. Option C, copper and iron, is not a standard alloy of this kind, though iron and copper occur together in the ore copper pyrites. Related alloys are worth learning with these: German silver is copper, zinc and nickel; gun metal is copper, tin and zinc; and bell metal is copper with a larger proportion of tin.

The correct answer is A, Ministry of Home Affairs. The National Human Rights Commission works under the administrative control of the Ministry of Home Affairs, which is the nodal ministry for human rights in India. The Commission is a statutory body, not a constitutional one, created by the Protection of Human Rights Act, 1993, and it began work on 12 October 1993. It is headed by a former Chief Justice of India or a judge of the Supreme Court, appointed by the President on the advice of a committee led by the Prime Minister, and it inquires into complaints of violation of human rights or of negligence by a public servant, though its recommendations are advisory. Option B is wrong because the Defence Ministry deals with the armed forces. Option C is wrong because the Finance Ministry handles revenue and expenditure. Option D is wrong because option A is right. Exam tip: NHRC is statutory, from the Protection of Human Rights Act 1993, under the Home Ministry.

The correct answer is B, Lungs. Pneumonia is an infection of the lungs in which the alveoli, the tiny air sacs where oxygen passes into the blood, fill with fluid or pus. That is why the patient has cough with phlegm, fever with chills, chest pain and difficulty in breathing, and the oxygen level in the blood can fall. It is caused most often by the bacterium Streptococcus pneumoniae, and also by other bacteria, viruses and fungi; it spreads through droplets, and children and the elderly are the worst affected. Vaccines against pneumococcus and influenza give protection. Option A is wrong because the kidney is affected by nephritis and kidney stones. Option C is wrong because the liver is affected by hepatitis, jaundice and cirrhosis. Option D is wrong because the heart is affected by conditions such as rheumatic heart disease and myocarditis. Exam tip: pneumonia and tuberculosis attack the lungs, hepatitis the liver, nephritis the kidney.

The correct answer is C, Graphite. Among the allotropes of carbon, graphite has the lowest standard enthalpy of formation, which is taken as zero, so it is the reference state and the most stable form under ordinary conditions of temperature and pressure. In graphite each carbon atom is sp2 hybridised and bonded to three others in flat hexagonal sheets, and the loose sheets slide over one another, which makes it soft and a good lubricant; the spare electron in each atom makes graphite a conductor of electricity. Option A is wrong because coal is not a pure allotrope but an impure mixture of carbon with hydrogen, sulphur and mineral matter. Option B is wrong because fullerenes such as C60 are strained cage molecules and are less stable than graphite. Option D is wrong because diamond, though the hardest natural substance, is slightly higher in energy and turns to graphite very slowly. Exam tip: graphite most stable and conducts electricity, diamond hardest and does not.

The correct answer is A. Protecting monuments and places of national importance is not a fundamental duty; it is a directive principle under Article 49, which asks the State to protect monuments and objects of artistic or historic interest declared to be of national importance. The fundamental duties sit in Article 51A in Part IV A, added by the 42nd Amendment in 1976 on the recommendation of the Swaran Singh Committee. They were ten in number and became eleven when the 86th Amendment of 2002 added the duty of a parent to give education to a child between six and fourteen. Option B is a duty under Article 51A(g), on the natural environment including forests, lakes, rivers and wildlife. Option C is a duty under Article 51A(i), which also asks citizens to abjure violence. Option D is a duty under Article 51A(a), respecting the Constitution, the National Flag and the National Anthem. Exam tip: fundamental duties Article 51A, Part IV A, 42nd Amendment 1976, now eleven.

The correct answer is A, Decrease in potential energy. A conservative force is one whose work depends only on the starting and the finishing point, not on the path taken, and whose work around any closed path is zero. Gravity and the spring force are the common examples. Potential energy is defined for such a force by the relation that the work it does equals the loss in potential energy. When a stone falls, gravity does positive work and the stone’s potential energy falls by exactly that amount. Option C is wrong because it states the opposite; potential energy rises only when work is done against the force, as in lifting the stone. Option B is right only when the conservative force is the sole force acting, so it is not the defining statement, and friction or an applied force would break it. Option D is wrong because kinetic energy grows, not falls, when such work is positive. Exam tip: conservative force, work equals minus the change in potential energy, and zero on a closed loop.

The correct answer is C, 24 January. On 24 January 1950, two days before the Constitution came into force, the United Provinces was officially renamed Uttar Pradesh. The state government began celebrating this date as Uttar Pradesh Diwas, or UP Foundation Day, in 2018, with events across the state showing its culture, crafts and achievements. The One District One Product (ODOP) scheme, which promotes a special product from each district, was launched on the first UP Diwas in 2018. Conveniently, the short form ‘U.P.’ stayed the same, since both names begin with the same letters. Option A is wrong because 26 January is Republic Day, when the Constitution came into force in 1950. Option B is wrong because 25 January is National Voters’ Day, marking the founding of the Election Commission in 1950, and also Himachal Pradesh’s statehood day. Option D is wrong because 23 January is the birth anniversary of Netaji Subhas Chandra Bose, observed as Parakram Diwas. Exam tip: on 24 January 1950 the United Provinces became Uttar Pradesh; the day has been celebrated as UP Diwas since 2018.

The correct answer is D, Bolivia. A landlocked country has no coastline on an open sea or ocean. South America has only two such countries, Bolivia and Paraguay. Bolivia once had a Pacific coast, but it lost that coastal province to Chile in the War of the Pacific (1879–1884) and has been landlocked ever since. It still keeps a navy, which patrols Lake Titicaca, the lake it shares with Peru and one of the highest navigable lakes in the world. La Paz is the seat of government, while Sucre is the constitutional capital. Option A is wrong because Uruguay lies on the Atlantic coast, and its capital Montevideo stands on the Rio de la Plata estuary. Option B is wrong because Suriname has an Atlantic coastline in the north of the continent, with Paramaribo as its port capital. Option C is wrong because Peru has a long Pacific coast, with Lima and the port of Callao. Exam tip: South America’s two landlocked countries are Bolivia and Paraguay.

The correct answer is A, 82° 30′ E longitude. India keeps one standard time for the whole country, Indian Standard Time, based on the 82° 30′ E meridian, which passes near Mirzapur in Uttar Pradesh. Since the Earth turns one degree every 4 minutes, 82.5 degrees gives 330 minutes, so IST is 5 hours 30 minutes ahead of Greenwich Mean Time. The meridian was chosen because it runs roughly through the middle of India’s east-west spread of about 30 degrees of longitude, from about 68° 7′ E in Gujarat to 97° 25′ E in Arunachal Pradesh. That spread makes the sun rise nearly two hours earlier in Arunachal than in Gujarat. The line passes through five states: Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Odisha and Andhra Pradesh. Option B is wrong because 83° 30′ E is one degree too far east. Option C is wrong because 82° E is half a degree short of the standard meridian. Option D is wrong because 82° 50′ E is not the chosen line either. Exam tip: 82° 30′ E × 4 minutes = 5 hours 30 minutes ahead of GMT.

The correct answer is C, 86th Constitutional Amendment Act, 2002. The 86th Amendment inserted Article 21A, which makes free and compulsory education for all children aged 6 to 14 years a Fundamental Right, in the manner the State decides by law. The same amendment rewrote Article 45 so that the State should provide early childhood care and education until age six, and added Fundamental Duty 51A(k), making parents and guardians responsible for giving their children education. The law that gives effect to Article 21A, the Right of Children to Free and Compulsory Education Act, 2009, came into force on 1 April 2010. Option A is wrong because the 103rd Amendment (2019) created 10 per cent reservation for economically weaker sections. Option B is wrong because the 93rd Amendment (2005) added Article 15(5), allowing reservation in educational institutions, including private ones. Option D is wrong because the 71st Amendment (1992) added Konkani, Manipuri and Nepali to the Eighth Schedule. Exam tip: the 86th Amendment made three changes: Article 21A, a new Article 45 and duty 51A(k).

The correct answer is B, Rabindranath Tagore. On 13 April 1919, General Dyer’s troops fired on an unarmed crowd at Jallianwala Bagh in Amritsar, killing hundreds. At the end of May 1919 Tagore wrote to the Viceroy, Lord Chelmsford, giving up the knighthood he had received in 1915, saying that such badges of honour had become a mark of shame. The poet had won the Nobel Prize for Literature in 1913 for Gitanjali, so his protest carried great weight across the world. Option A is wrong because M. A. Jinnah resigned from the Imperial Legislative Council in March 1919 in protest against the Rowlatt Act; he returned no knighthood. Option C is wrong because Maharaja Rameshwar Singh of Darbhanga was a loyal supporter of the government and gave up no title. Option D is wrong because Sir C. Sankaran Nair protested by resigning from the Viceroy’s Executive Council, not by returning his knighthood. Exam tip: Tagore gave up his knighthood in 1919; Gandhi returned the Kaiser-i-Hind medal in 1920.
