Defence 2023 Previous Year GK Questions with Answers

The correct answer is B, Second Five Year Plan. The Second Plan (1956 to 1961) was built on the model of the statistician P. C. Mahalanobis and aimed at rapid industrialisation with a stress on heavy and basic industries such as steel, machinery and chemicals, on the belief that machines to make machines would speed up growth. The three public sector steel plants at Bhilai, Rourkela and Durgapur, set up with Soviet, German and British help, belong to this plan, and the Industrial Policy Resolution of 1956 gave the public sector the commanding heights of the economy. The plan ran into a foreign exchange crisis and its target growth of 4.5 percent was not fully met. A, the First Plan (1951 to 1956), followed the Harrod-Domar model and gave priority to agriculture, irrigation and power. C, the Fifth Plan (1974 to 1979), focused on poverty removal and self-reliance under the slogan Garibi Hatao. D, the Seventh Plan (1985 to 1990), stressed food, work and productivity. Exam tip: Second Plan means the Mahalanobis model, heavy industry, and Bhilai, Rourkela, Durgapur.

The correct answer is A, 243ZD. Article 243ZD was inserted by the 74th Constitutional Amendment Act of 1992, which added Part IX-A on Municipalities. It requires every state to set up a District Planning Committee in each district to consolidate the plans prepared by the panchayats and the municipalities of the district and to prepare a draft development plan for the district as a whole.

D, Article 243ZC, says that Part IX-A does not apply to the Scheduled Areas and tribal areas under Article 244. Exam tip: remember the run 243ZD district planning, 243ZE metropolitan planning, and that both came with the 74th Amendment of 1992.

The correct answer is A, The Constitution (42nd Amendment) Act. The 42nd Amendment of 1976, passed on the recommendation of the Swaran Singh Committee, added a new Part IV-A with a single Article 51A listing ten Fundamental Duties of citizens, such as respecting the Constitution, the National Flag and the National Anthem, protecting the environment and developing the scientific temper.

The correct answer is B, Wheat. Western disturbances are low-pressure systems that originate over the Mediterranean Sea and travel eastward with the subtropical westerly jet stream in winter, bringing light rain to Punjab, Haryana, western Uttar Pradesh and Delhi, and snow to the Himalaya, between December and February. Wheat is the main rabi crop, sown in October and November and harvested in March and April, and it needs cool weather and a little rain during its growing period; this winter rain, called mahawat in north India, is described as gold for wheat because it saves a round of irrigation and improves the grain. A, Rice, is a kharif crop that depends on the heavy rain of the south-west monsoon. C, Bajra, is a kharif millet of the dry areas of Rajasthan and Gujarat, grown on monsoon rain. D, Cotton, is also a kharif crop, sown at the start of the monsoon and picked in autumn. Exam tip: western disturbances bring the winter rain of north-west India, which is good for the rabi crops wheat, barley, gram and mustard.

The correct answer is C, Warren Hastings. Warren Hastings was the first Governor-General of Bengal under the Regulating Act of 1773 and held office from 1773 to 1785. After he returned to England, the House of Commons impeached him in 1787 on charges of corruption and misrule, including his treatment of Raja Chait Singh of Banaras and the Begums of Awadh. Edmund Burke led the prosecution, and the trial before the House of Lords ran from 1788 to 1795, ending in his acquittal on every charge. It remains the most famous impeachment in British history. A, Robert Clive, was Governor of Bengal, faced a parliamentary inquiry in 1773 but was never impeached, and died in 1774. B, Henry Vansittart, was Governor of Bengal from 1760 to 1764 and faced no impeachment. D, Lord Cornwallis, succeeded Hastings and is known for the Permanent Settlement of 1793. Exam tip: Hastings, first Governor-General of Bengal, impeached 1787, acquitted 1795.

The correct answer is A, Harishena. The Prayag Prashasti, also called the Allahabad Pillar Inscription, is a Sanskrit eulogy of the Gupta emperor Samudragupta (about 335 to 375 CE) composed by his court poet and minister Harishena, who held the titles sandhivigrahika (minister of peace and war) and kumaramatya. It is engraved on the Ashokan pillar now at Allahabad Fort and lists the kings Samudragupta defeated in the north (uprooted) and in the south (defeated and released), which is why historians call him the Napoleon of India. Written in the champu style, it also describes him as a poet and musician. B, Chand Bardai, wrote the Prithviraj Raso in the twelfth century. C, Vishakhadatta, wrote the play Mudrarakshasa about Chandragupta Maurya and Chanakya. D, Kalidasa, the poet of Abhijnanashakuntalam and Meghaduta, is linked to Chandragupta II, not to this inscription. Exam tip: Harishena, Prayag Prashasti, Samudragupta; Ravikirti, Aihole inscription, Pulakeshin II.

The correct answer is C, Newtonian telescope. Isaac Newton built the first practical reflecting telescope in 1668. In it, light from the star falls on a large concave mirror at the bottom of the tube, and a small flat mirror set at 45 degrees near the top turns the light sideways to the eyepiece. Because the objective is a mirror and not a lens, there is no chromatic aberration, the colour fringing that lenses produce, and a mirror can be made much larger and lighter than a lens. Most big observatory telescopes are therefore reflectors. A, the Galilean telescope, is a refractor using a convex objective lens and a concave eyepiece lens. B, the Keplerian telescope, is also a refractor, with two convex lenses, and gives an inverted image. D, the Schmidt telescope, is a catadioptric design that combines a spherical mirror with a glass corrector plate, so it is not mirrors only. Exam tip: refractor means lenses (Galileo, Kepler), reflector means mirrors (Newton), Schmidt means a mirror plus a corrector lens.

The correct answer is B, A bottle opener. Levers are grouped by where the fulcrum, the load and the effort sit. In a second class lever the load lies between the fulcrum and the effort. In a bottle opener the rim of the cap is the fulcrum at the tip, the cap being lifted is the load in the middle, and your hand applies the effort at the far end. Such levers always multiply force because the effort arm is longer; a wheelbarrow and a nutcracker work the same way. A, A pair of scissors, is a first class lever, with the pivot between the effort and the load. C, A cricket bat, is a third class lever: the lower hand applies the effort between the top hand, which acts as the fulcrum, and the ball. D, A bow and arrow, works by storing energy in the bent bow like a spring, not by placing the load between the fulcrum and the effort. Exam tip: first class has the fulcrum in the middle, second class the load in the middle, third class the effort in the middle.

The correct answer is C, Zinc. Galvanisation is the coating of iron or steel with a thin layer of zinc so that the iron underneath does not rust. Zinc sits above iron in the reactivity series, so even when the coating is scratched, zinc corrodes first and keeps protecting the iron; this is called sacrificial protection. The zinc layer is usually put on by dipping the article in molten zinc (hot-dip galvanising) or by electroplating. Galvanised sheets are used for roofs, water pipes, buckets and electricity poles. A, Gallium, is a rare, low-melting metal and is never used for rust protection. B, Aluminum, forms its own protective oxide layer, but coating iron with aluminium is not called galvanisation. D, Silver, is too costly and is less reactive than iron, so it would not protect it sacrificially. Exam tip: galvanisation means a zinc coating on iron; a tin coating on iron is called tinning.
