Q63.Indian PolityAsked in: SSC CGL · 26 Jul 2023, Shift 3Hard

Which Article of the Indian Constitution empowers the Parliament to establish additional courts for better administration of laws made by it?

  1. A.Article 246
  2. B.Article 248
  3. C.Article 253
  4. D.Article 247
Show answer

Correct answer: D. Article 247

Explanation

The correct answer is D, Article 247. It gives Parliament the power to provide by law for additional courts so that laws made by Parliament, or older laws on Union List subjects, are administered better. The Article sits in Part XI, Chapter I, which deals with the division of law-making power between the Union and the States (Articles 245 to 255). The word to catch in the question is "additional courts": only Article 247 talks about courts in this chapter, the neighbouring Articles talk about subjects and lists. A, Article 246, distributes subjects among the Union List, State List and Concurrent List of the Seventh Schedule. B, Article 248, gives the residuary power, that is, power over any matter not in the State or Concurrent List, to Parliament. C, Article 253, lets Parliament make laws for the whole country to implement treaties and international agreements. Exam tip: 246 three lists, 247 additional courts, 248 residuary power, 253 international agreements.

Q64.Indian PolityAsked in: SSC CGL · 24 Jul 2023, Shift 1Medium

Which Article of the Constitution of India mentions that law declared by Supreme Court is binding on all courts?

  1. A.Article 143
  2. B.Article 142
  3. C.Article 144
  4. D.Article 141
Show answer

Correct answer: D. Article 141

Explanation

The correct answer is D, Article 141. It says that the law declared by the Supreme Court shall be binding on all courts within the territory of India. This Article is the constitutional base of the doctrine of precedent: a ruling of the Supreme Court becomes the law for every High Court and lower court until the Supreme Court itself changes it. Note the exact words, because they are lifted straight into exam questions: "law declared", "binding on all courts", "within the territory of India". A, Article 143, is the advisory jurisdiction under which the President may seek the opinion of the Supreme Court. B, Article 142, lets the Court pass any order needed to do complete justice in a case. C, Article 144, directs all civil and judicial authorities to act in aid of the Supreme Court. Exam tip: remember the run 141 binding law, 142 complete justice, 143 advice to the President, 144 authorities act in aid.

Q65.Indian EconomyAsked in: RRB NTPC · 12 Jun 2022, Shift 2 (CBT 2, Level 5)Medium

The situation in an economy when inflation and unemployment both are at higher levels is known as __________.

  1. A.stagflation
  2. B.inflation premium
  3. C.inflationary gap
  4. D.reflation
Show answer

Correct answer: A. stagflation

Explanation

The correct answer is A, stagflation. Stagflation is a blend of the words stagnation and inflation: output stops growing, unemployment rises, and yet prices keep climbing. Normally inflation and unemployment move in opposite directions, as the Phillips curve shows, so stagflation is a puzzle for policy makers, because raising interest rates to cool prices worsens unemployment while spending to create jobs pushes prices higher. The classic example is the 1970s, when the oil price shocks of 1973 and 1979 hit western economies with slow growth and double-digit inflation at the same time. B is wrong because an inflation premium is the extra return lenders demand to make up for expected inflation. C is wrong because an inflationary gap is the amount by which total demand exceeds full-employment output, a situation of too much demand, not of high unemployment. D is wrong because reflation is a deliberate policy of boosting demand to lift an economy out of a slump. Exam tip: stagflation equals high inflation plus high unemployment plus stagnant growth, remembered by the 1970s oil crisis.

Q66.Indian HistoryAsked in: RRB NTPC · 12 Jun 2022, Shift 1 (CBT 2, Level 5)Medium

The Sanskrit drama 'Ratnavali', about the love story of Princess Ratnavali is said to have been written by ________.

  1. A.Kalidasa
  2. B.Harsha
  3. C.Bhavabhuti
  4. D.Vishakhadutta
Show answer

Correct answer: B. Harsha

Explanation

The correct answer is B, Harsha. Ratnavali is one of three Sanskrit plays attributed to Emperor Harshavardhana of Kannauj, who ruled from 606 to 647 CE; the other two are Priyadarshika and Nagananda. Ratnavali tells how Princess Ratnavali of Simhala, living in disguise as Sagarika, wins the love of King Udayana of Vatsa. Harsha was a great patron of learning as well as a writer: Banabhatta lived at his court and wrote Harshacharita and Kadambari, the Chinese pilgrim Hiuen Tsang visited him, and he held assemblies at Kannauj and Prayag. A is wrong because Kalidasa, of the Gupta age, wrote Abhijnanashakuntalam, Meghaduta and Raghuvamsha. C is wrong because Bhavabhuti, in the court of Yashovarman, wrote Uttararamacharita and Malatimadhava. D is wrong because Vishakhadatta wrote Mudrarakshasa about Chanakya and Chandragupta Maurya. Exam tip: Harsha's three plays are Ratnavali, Priyadarshika and Nagananda; his biographer was Banabhatta.

Q67.Indian PolityAsked in: RRB NTPC · 14 Jun 2022, Shift 2 (CBT 2, Level 3)Easy

Fill in the blank using words contained in the Preamble to the Constitution of India: We, ______, having solemnly resolved to constitute India into a SOVEREIGN SOCIALIST SECULAR DEMOCRATIC REPUBLIC and to secure to all its citizens....

  1. A.The Supreme Court
  2. B.The Indian Parliament
  3. C.The Central Government
  4. D.The People of India
Show answer

Correct answer: D. The People of India

Explanation

The correct answer is D, The People of India. The Preamble opens with the words WE, THE PEOPLE OF INDIA, which declare that the Constitution draws its authority from the people, not from any king, court or legislature. It goes on to promise Justice, Liberty, Equality and Fraternity, and ends by recording that the Constituent Assembly adopted, enacted and gave the Constitution to ourselves on 26 November 1949. The Preamble is based on Nehru's Objectives Resolution of 1946; the words Socialist, Secular and Integrity were added by the 42nd Amendment in 1976; and in the Kesavananda Bharati case (1973) the Supreme Court held that the Preamble is a part of the Constitution. A is wrong because the Supreme Court is created by the Constitution and cannot be its author. B is wrong because Parliament too gets its powers from the Constitution. C is wrong because the Central Government is only an organ that works under the Constitution. Exam tip: Preamble begins We the People, adopted 26 November 1949, amended once in 1976.

Q68.GeographyAsked in: RRB NTPC · 14 Jun 2022, Shift 1 (CBT 2, Level 3)Medium

Which of the following river basins is the most populated in the world?

  1. A.Ganga
  2. B.Nile
  3. C.Mississippi
  4. D.Amazon
Show answer

Correct answer: A. Ganga

Explanation

The correct answer is A, Ganga. The Ganga basin is the most populous river basin on earth, home to more than 600 million people across India, Nepal, Bangladesh and a small part of Tibet. In India alone it covers about 8.6 lakh square km, roughly a quarter of the country, across Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Haryana, Delhi and parts of Madhya Pradesh, Rajasthan and Chhattisgarh, and it supports about 40 percent of India's population. Fertile alluvial soil, plentiful groundwater and a long farming history explain the dense settlement. B is wrong because the Nile, though the longest river, flows mostly through desert and its basin holds far fewer people. C is wrong because the Mississippi basin lies in the thinly populated interior of the USA. D is wrong because the Amazon has the largest discharge and basin area but its rainforest is among the least populated regions on earth. Exam tip: Ganga is the most populated basin; Amazon is the largest by area and water; Nile is the longest river.

Q69.Indian EconomyAsked in: RRB NTPC · 16 Jun 2022, Shift 3 (CBT 2, Level 2)Medium

________ refer to central bank purchases or sales of government securities in order to expand or contract money in the banking system and influence interest rates.

  1. A.National market operations
  2. B.Closed market operations
  3. C.Open market operations
  4. D.International market operations
Show answer

Correct answer: C. Open market operations

Explanation

The correct answer is C, Open market operations. Open market operations, or OMO, are the buying and selling of government securities by the central bank in the open market to control the money supply. When the RBI buys government bonds it pays money to banks, so liquidity in the system rises and interest rates tend to fall; when it sells bonds it pulls money out, tightening liquidity and pushing rates up. OMO is a quantitative tool of monetary policy, used along with the cash reserve ratio, the statutory liquidity ratio, the repo rate and the bank rate, and the RBI also uses it to manage the government's borrowing programme. A is wrong because national market operations is not a term used in monetary policy. B is wrong because closed market operations does not exist; the whole point is that the trades happen in the open market. D is wrong because international market operations would refer to foreign exchange dealings, not government securities. Exam tip: RBI buys securities means more money, RBI sells securities means less money; that is OMO.

Q70.Indian PolityAsked in: RRB NTPC · 16 Jun 2022, Shift 2 (CBT 2, Level 2)Medium

Financial emergency can be declared under __________ of the Constitution of India.

  1. A.Article 356
  2. B.Article 359
  3. C.Article 360
  4. D.Article 352
Show answer

Correct answer: C. Article 360

Explanation

The correct answer is C, Article 360. Article 360 lets the President proclaim a financial emergency when the financial stability or credit of India, or of any part of it, is threatened. Such a proclamation must be approved by both Houses of Parliament within two months, after which it continues indefinitely until revoked; there is no maximum period. During it the Union can direct states to follow canons of financial propriety, and salaries of government servants, including Supreme Court and High Court judges, can be reduced. No financial emergency has ever been declared in India, though it was discussed during the 1991 crisis. D is wrong because Article 352 is the national emergency on grounds of war, external aggression or armed rebellion, imposed in 1962, 1971 and 1975. A is wrong because Article 356 is President's rule, imposed when a state's constitutional machinery fails. B is wrong because Article 359 only suspends the enforcement of fundamental rights during a national emergency. Exam tip: 352 national, 356 state, 360 financial; only 360 has never been used.

Q71.General ScienceAsked in: RRB NTPC · 16 Jun 2022, Shift 1 (CBT 2, Level 2)Medium

Water has the highest density at nearly ______ Kelvin.

  1. A.0
  2. B.227
  3. C.277
  4. D.273
Show answer

Correct answer: C. 277

Explanation

The correct answer is C, 277. Water is densest at about 4 degrees Celsius, and 4 plus 273 gives roughly 277 kelvin. Most liquids keep shrinking as they cool, but water behaves oddly: below 4 degrees Celsius it starts to expand again because its molecules begin forming the open, hexagonal pattern of ice. This anomalous expansion is why ice is lighter than water and floats, and why a lake freezes from the top while the 4-degree water sinks to the bottom, letting fish survive the winter. Its density at that point is very close to 1 gram per cubic centimetre. D is wrong because 273 kelvin is 0 degrees Celsius, the freezing point, where water is already less dense than at 4 degrees. A is wrong because 0 kelvin is absolute zero, where no liquid water can exist. B is wrong because 227 kelvin is about minus 46 degrees Celsius, far below freezing. Exam tip: maximum density of water at 4 degrees Celsius equals 277 K; freezing at 273 K, boiling at 373 K.

Q72.Important Days & DatesAsked in: RRB NTPC · 13 Jun 2022, Shift 2 (CBT 2, Level 2)Easy

The National Unity Day is celebrated in India on the birth anniversary of ________.

  1. A.Dr BR Ambedkar
  2. B.Indira Gandhi
  3. C.Sardar Vallabhbhai Patel
  4. D.Mother Teresa
Show answer

Correct answer: C. Sardar Vallabhbhai Patel

Explanation

The correct answer is C, Sardar Vallabhbhai Patel. National Unity Day, or Rashtriya Ekta Diwas, is observed on 31 October, the birth anniversary of Sardar Patel, who was born in 1875 at Nadiad, Gujarat. The day was started in 2014 to honour his role as the first Deputy Prime Minister and Home Minister who brought more than 560 princely states into the Indian Union, earning him the title Iron Man of India. It is marked with a Run for Unity and a unity pledge, and on 31 October 2018 the 182-metre Statue of Unity was unveiled in his memory at Kevadia on the Narmada. A is wrong because Dr Ambedkar's birth anniversary, 14 April, is Ambedkar Jayanti. B is wrong because Indira Gandhi's birthday, 19 November, is observed as National Integration Day. D is wrong because Mother Teresa was born on 26 August, which is not a national day. Exam tip: 31 October means Sardar Patel, National Unity Day and the Statue of Unity.

Q73.Indian HistoryAsked in: RRB NTPC · 13 Jun 2022, Shift 1 (CBT 2, Level 2)Easy

Who among the following denounced the injustice of the caste system and founded the Satyashodhak Samaj (Truth Seekers Society)?

  1. A.Savitri Bai Phule
  2. B.EV Ramasamy Naicker
  3. C.Ayyankali
  4. D.Jyotirao Govindrao Phule
Show answer

Correct answer: D. Jyotirao Govindrao Phule

Explanation

The correct answer is D, Jyotirao Govindrao Phule. Jyotiba Phule founded the Satyashodhak Samaj at Pune on 24 September 1873 to fight caste discrimination and the hold of priests over society. The same year he published Gulamgiri (Slavery), attacking Brahmanical domination, and earlier, in 1848, he and his wife Savitribai had opened one of the first schools for girls in Pune. The Samaj promoted education for Shudras, Dalits and women, marriages without priests, and equality; Phule was given the title Mahatma in 1888, and Dr Ambedkar counted him among his three gurus. A is wrong because Savitribai Phule, though a pioneer of women's education and a member of the Samaj, was not its founder. B is wrong because E. V. Ramasamy Periyar led the Self-Respect Movement in Tamil Nadu from 1925. C is wrong because Ayyankali was a Dalit reformer of Kerala who set up the Sadhu Jana Paripalana Sangham in 1907. Exam tip: Satyashodhak Samaj, Pune, 1873, Jyotiba Phule, book Gulamgiri.

Q74.Indian PolityAsked in: RRB NTPC · 13 Jun 2022, Shift 1 (CBT 2, Level 2)Medium

Which Amendment to the Constitution of India removed the 'Right to property' from the Fundamental Rights?

  1. A.46th Constitutional Amendment 1980
  2. B.44th Constitutional Amendment 1978
  3. C.42nd Constitutional Amendment 1976
  4. D.48th Constitutional Amendment 1981
Show answer

Correct answer: B. 44th Constitutional Amendment 1978

Explanation

The correct answer is B, 44th Constitutional Amendment 1978. The 44th Amendment, passed by the Janata Party government of Morarji Desai, took the right to property out of Part III of the Constitution. It deleted Article 19(1)(f) and Article 31, which had guaranteed the right to acquire, hold and dispose of property, and put in their place Article 300A, which says no person shall be deprived of property except by authority of law. Property thus became a legal or constitutional right, not a fundamental one, from 20 June 1979, so a citizen can no longer go straight to the Supreme Court under Article 32 for it. C is wrong because the 42nd Amendment of 1976 added the words Socialist, Secular and Integrity and the Fundamental Duties; it did not remove property. A is wrong because the 46th Amendment (actually of 1982) dealt with sales tax on goods. D is wrong because the 48th Amendment (1984) extended President's rule in Punjab. Exam tip: 42nd added Fundamental Duties, 44th removed the fundamental right to property (now Article 300A).

Q75.Indian HistoryAsked in: RRB NTPC · 9 May 2022, Shift 2 (CBT 2, Level 6)Easy

Kalhana's Rajatarangini in Sanskrit language covers the history of kings who ruled over _____.

  1. A.Bengal
  2. B.Bihar
  3. C.Kashmir
  4. D.Delhi
Show answer

Correct answer: C. Kashmir

Explanation

The correct answer is C, Kashmir. Rajatarangini, meaning the river of kings, is a Sanskrit verse chronicle of the rulers of Kashmir written by Kalhana around 1148–1150 CE. It runs to about 8,000 verses arranged in eight books called tarangas, or waves, and traces Kashmir's kings from legendary times down to Kalhana's own day in the reign of Jayasimha. Because Kalhana used inscriptions, coins, older records and his own judgement, it is often called the first real work of history written in India. Later authors Jonaraja, Srivara and Prajyabhatta continued the story into the Mughal period. A is wrong because Bengal's rulers are recorded in works like Ramacharita of Sandhyakara Nandi, not in Rajatarangini. B is wrong because Bihar was the seat of Magadha and the Palas, who are not the book's subject. D is wrong because the Delhi Sultans are covered by Persian chronicles such as Tabaqat-i-Nasiri. Exam tip: Kalhana, Rajatarangini, Kashmir, 12th century, eight tarangas.

Q76.Indian PolityAsked in: RRB NTPC · 9 May 2022, Shift 2 (CBT 2, Level 6)Medium

Goa became India's 25th state on _________________.

  1. A.30 May 1990
  2. B.30 May 1986
  3. C.30 May 1987
  4. D.30 May 1988
Show answer

Correct answer: C. 30 May 1987

Explanation

The correct answer is C, 30 May 1987. Goa became a full state on 30 May 1987 through the Constitution (56th Amendment) Act and the Goa, Daman and Diu Reorganisation Act, and the day is celebrated every year as Goa Statehood Day. Goa had been freed from Portuguese rule on 19 December 1961 in Operation Vijay and was then run as the Union Territory of Goa, Daman and Diu. In 1987 Goa was separated and raised to statehood, while Daman and Diu stayed a union territory; Konkani was made the official language and Panaji the capital. Earlier the same year, on 20 February 1987, Mizoram and Arunachal Pradesh had become the 23rd and 24th states, so Goa took the 25th place. B is wrong because in 1986 Goa was still a union territory. D and A are wrong because by 1988 and 1990 Goa had already been a state for one and three years. Exam tip: liberated 1961, state 30 May 1987, 25th state after Mizoram (23rd) and Arunachal Pradesh (24th).

Q77.General ScienceAsked in: RRB NTPC · 9 May 2022, Shift 1 (CBT 2, Level 6)Medium

Which of the following is an element with atomic number 30 as per the modern periodic table?

  1. A.Ni
  2. B.Fe
  3. C.Zn
  4. D.Co
Show answer

Correct answer: C. Zn

Explanation

The correct answer is C, Zn. Zinc has atomic number 30, meaning every zinc atom has 30 protons in its nucleus. It is the last element of the first transition series in period 4 of the modern periodic table, with the electronic configuration [Ar] 3d10 4s2, and it is placed in group 12. Zinc is a bluish-white metal used to galvanise iron against rust, to make brass with copper, and in dry cells. All four options are neighbours in the same period, which is why paper setters like this question: iron is 26, cobalt 27, nickel 28, copper 29 and zinc 30. A is wrong because Ni, nickel, has atomic number 28. B is wrong because Fe, iron, has atomic number 26. D is wrong because Co, cobalt, has atomic number 27. Exam tip: remember the run Fe 26, Co 27, Ni 28, Cu 29, Zn 30.

Q78.GeographyAsked in: RRB NTPC · 9 May 2022, Shift 1 (CBT 2, Level 6)Easy

Majuli, the largest riverine island in the world, is associated with which of the following rivers?

  1. A.Brahmaputra
  2. B.Ganga
  3. C.Indus
  4. D.Godavari
Show answer

Correct answer: A. Brahmaputra

Explanation

The correct answer is A, Brahmaputra. Majuli lies in the Brahmaputra river in Assam, near Jorhat, and is the largest river island in the world. In 2016 it became India's first island district. It is the heart of Assam's neo-Vaishnavite culture: the saint Srimanta Sankardeva and his disciple Madhavdeva set up satras (monasteries) there in the 15th and 16th centuries, and the island is famous for its mask-making and the Raas festival. Every monsoon the Brahmaputra eats away its banks, so Majuli has shrunk from over 1,200 square km to less than half of that, making erosion its biggest worry. B is wrong because the Ganga has no comparable island; its delta islands such as Sagar belong to the Sundarbans. C is wrong because the Indus flows mainly through Pakistan and has no such island. D is wrong because the Godavari's Konaseema is a delta region, not a single river island. Exam tip: Majuli equals Brahmaputra equals Assam, first island district of India (2016).

Q79.General ScienceAsked in: RRB NTPC · 7 Jan 2021, Shift 2 (CBT 1)Medium

Which of the following devices is used to measure relatively high temperatures, such as encountered in furnaces?

  1. A.Bolometer
  2. B.Pyrometer
  3. C.Ammeter
  4. D.Fluxmeter
Show answer

Correct answer: B. Pyrometer

Explanation

The correct answer is B, Pyrometer. A pyrometer measures very high temperatures, such as those of furnaces, kilns and molten metal, without touching the hot object. It works on the principle that every hot body gives off thermal radiation whose intensity and colour depend on its temperature; the instrument reads this radiation and converts it into a temperature value. Ordinary mercury thermometers stop at about 350 degrees Celsius, so steel plants, glass works and cement kilns rely on pyrometers, which can read well above 1,000 degrees Celsius. The word comes from the Greek pyro, meaning fire. A is wrong because a bolometer measures the power of incident electromagnetic radiation, such as infrared or microwaves, not furnace temperature. C is wrong because an ammeter measures electric current in amperes. D is wrong because a fluxmeter measures magnetic flux. Exam tip: pyrometer for furnace heat, thermometer for body heat, ammeter for current, fluxmeter for magnetism.

Q80.GeographyAsked in: RRB NTPC · 7 Jan 2021, Shift 2 (CBT 1)Easy

The quartzite is a ________ type of rock.

  1. A.igneous
  2. B.basalt
  3. C.sedimentary
  4. D.metamorphic
Show answer

Correct answer: D. metamorphic

Explanation

The correct answer is D, metamorphic. Quartzite is formed when sandstone, a sedimentary rock, is changed by great heat and pressure deep inside the earth. The quartz grains of the sandstone recrystallise and fuse, so quartzite becomes one of the hardest and most weather-resistant rocks, which is why the ridges of the Aravalli range and the Delhi Ridge, made largely of quartzite, have survived for hundreds of millions of years. Such change of an existing rock without melting is called metamorphism. A is wrong because igneous rocks such as granite and basalt form from cooled magma or lava, not from an older rock under pressure. B is wrong because basalt is itself a specific igneous rock, not a class of rock. C is wrong because sedimentary is the parent type; sandstone is sedimentary, but once transformed it is no longer classed that way. Exam tip: sandstone becomes quartzite, limestone becomes marble, shale becomes slate, granite becomes gneiss.
