Correct option (c) Arnold Toynbee  

Explanation:

Although used earlier by French writers, the term Industrial Revolution was first popularized by the English economic historian Arnold Toynbee (1852–83) to describe Britain’s economic development from 1760 to 1840. Since Toynbee’s time the term has been more broadly applied.

Correct option (c) Higher Education

Explanation:

The 11^th schedule enshrines the distribution of powers between the State legislature and the Panchayats. These 29 subjects are listed below: 

11^th Schedule of the Constitution

Out of the list given in item K, only, 'boy' is the correct answer because usually, a boy, and not a horse, a dog or a cow, attends school. So 'A' is to be marked on the Answer Sheet for item K. A boy is usually referred to as 'he', so for item L , 'C' is the correct answer. Notice that to solve the first item K you have to-read the rest of the sentence and then see what fits best.

Correct option  (d) Live microbial food supplement 

Explanation:

Probiotics are microorganisms that are claimed to provide health benefits when consumed. 

Probiotics are live bacteria and yeasts that are good for your health, especially your digestive system.

Correct option (d) Vitamin K

Explanation:

Vitamin K is a group of structurally similar, fat-soluble vitamins that the human body requires for complete synthesis of certain proteins that are prerequisites for blood coagulation. It is active as a vitamin in animals and performs the classic functions of vitamin K, including its activity in the production of blood-clotting proteins.

Correct option (c) It opposed the levy of tariff on imports

Explanation:

In fact, the Swadeshi Campaign in 1896 vouched for levying tariff on imports to promote the home-made products. Hence, statement C is incorrect.

Correct option (a) Lactic Acid Bacillus

Explanation:

The lactic acid curdles the milk that then separates to form curds, which are used to produce cheese and whey. 

Acidification of milk means lowering its pH. It causes the milk proteins to unwind and unfold in a process known as protein denaturing. Lactic Acid does the process in case of milk.

Correct option (a) Ultraviolet waves

Explanation:

Ultraviolet waves or UV rays are used for detecting fake and forged currency. The paper currency has a strip that is embedded in the note. This strip cannot be forged like that in the original currency. 

An authentic paper currency will fluoresce when it is illuminated by long wave ultraviolet light. 

Correct option (b) About 8 minutes

Explanation:

Sunlight travels at the speed of light. We orbit the Sun at a distance of about 150 million km. Light moves at 300,000 kilometers/second. Divide these and you get 500 seconds, or 8 minutes and 20 seconds. 

Correct option (b) distance

Explanation:

A light-year is a unit of distance, not time. A light-year is how astronomers measure distance in space.

As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year. It is equal to 9.4607 × 10¹⁵ m.

Correct option (d) increasing voltage

Explanation:

Transformers “step up” or “step down” voltage according to the ratios of primary to secondary wire turns. A transformer designed to increase voltage from primary to secondary is called a step-up transformer. A transformer designed to reduce voltage from primary to secondary is called a step-down transformer.

Correct option D.

Explanation:

P and R are mandatory pairs and they must follow the fixed part as they state the action that has been accomplished by the spirit of man. Surmount means to overcome, and obstacles are required to be overcome. Q follows R as the coordinating conjunction “and” introduces another aspect that the “spirit” of man has faced. Thus the correct sequence after rearrangement is PRQS and option D is the correct answer.

Correct option C. six times the mass percent of C as compared to the mass percent of H

Explanation:

There are 6.022 ×10²³ entities in 1 mole. 

Atomic mass of Carbon = 12 

Atomic mass of Hydrogen = 1| 

Atomic mass of Oxygen = 16 

Molecular mass 

= (6 × 12) + (12 × 1) + (4 × 16) 

= 72 + 12 + 64 = 148

Mass percentage of carbon

= 72/148 = 49% 

Mass percentage of hydrogen = 12/148 = 8% 

Mass percentage of oxygen = 64/148 = 43% 

Hence, correct option is (C). 

Correct option (a) Henry Vivian Derozio

Explanation:

Young Bengal Movement was launched by Henry Louis Vivian Derozio (1809- 1831), who had come to Calcutta in 1826 and was appointed in the Hindu College as a teacher of English literature and History. 

Besides this he edited Hesperus and Calcutta Literary Gazette. He was connected with India Gazette as well.

Only A option would have same number of electrons i.e. 16. In rest of the options, due to presence of charge, the number of electrons vary.

Correct option (d) holes

Explanation:

In p-type semiconductors, holes are the majority carriers and electrons are the minority carriers. 

The less abundant charge carriers are called minority carriers; in n-type semiconductors they are holes.

Correct option (a) in etching glass

Explanation:

Hydrofluoric (HF) acid, one of the strongest inorganic acids, is used mainly for industrial purposes (eg, glass etching, metal cleaning, electronics manufacturing).

Correct option (b) 13.6 eV

Explanation:

The ionization energy of hydrogen in its ground state is 13.6 eV 

For a hydrogen atom, composed of an orbiting electron bound to a nucleus of one proton, an ionization energy of 2.18 × 10⁻¹⁸ joule (13.6 electron volts) is required to force the electron from its lowest energy level entirely out of the atom.

Correct option (d) NaOH

Explanation:

Strong electrolyte is an ionic compound that dissociates completely in water & conducts electricity. 

From the given options, only NaOH and HCl are strong electrolytes and NaOH alone would form a basic solution when dissolved in water. 

NaOH is a strong electrolyte. It is an alkali-a water soluble strong base.

Correct option (b) Vitamin A

Explanation:

Golden rice is a variety of rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of rice. It is intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A.

Correct option (a) The centripetal acceleration of the object is smaller for a gentle curve (i.e., curve of larger radius) than that for a sharp curve (i.e., curve of smaller radius).  

Explanation:

Centripetal Acceleration is given by A= v^2/R, where v is the velocity and R is the radius of the curve.

Since the gentle curve has a larger radius, it has a smaller centripetal acceleration. 

Hence, A is the correct statement. 

Correct option (d) water vapour

Explanation:

When you first start to boil water, the bubbles are basically air bubbles. These are bubbles formed from the dissolved gases in water. The solubility of gases decreases when the temperature is increased, and that is why the dissolved air bubbles come out from the water. Then, as the boiling point of water is reached, water vapor starts to form in the form of bubbles.

Correct option (b) Decrease

Explanation:

An object weighs the same in air as well as in water. But, in water an additional buoyant force acts on the ball in a direction opposite to the direction in which the weight of the ball acts. If the weight of the ball acts downwards, buoyant force acts upwards. These two forces work together to make it seem as the object weighs less in water.

Correct option (a) the air pressure is less

Explanation: 

Water boils at a lower temperature at high altitudes. The boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure. A liquid boils when its vapor pressure exceeds the local total pressure.

Correct option (b) sends parallel rays

Explanation:

Concave mirrors are commonly used in not only vehicles headlights but also in torches and search-lights to get powerful parallel beams of light to focus the light at the longer distances by placing the source of light at the focus of the Concave mirrors.

Correct option (a) Ultraviolet radiation

Explanation:

Melanin is a protective pigment in skin, blocking UV radiation from damaging DNA and potentially causing skin cancer.

UVA radiation causes lesions or DNA damage to melanocytes, which are the skin cells that produce the skin pigment known as melanin.

Correct option (c) No antibiotic has been obtained from any microbe.

Explanation:

Hence, various antiobiotics are obtained from microbes.

Correct option (c) Wuchereria bancrofti

Explanation:

Elephantiasis tropica or lymphatic filariasis is caused by a number of parasitic worms, particularly Wuchereria bancrofti. 

W. bancrofti was named after physician Otto Wucherer and parasitologist Joseph Bancroft, both of whom extensively studied filarial infections like elephantiasis.

Correct option (b) Maurice Hugh Frederick Wilkins

Correct option (c) Subhash Chandra Bose

Explanation:

The great Indian Struggle, 1920–1942 is a two-part book by the Indian nationalist leader Netaji Subhash Chandra Bose that covers the 1920–1942 history of the Indian independence movement to end British imperial rule over India.

Correct option (c) 1 and 3 only

Explanation:

Percentage Fe in magnetite Fe₃O₄ is 168/(168 + 64)=72.4%. So, statement 2 is incorrect. 

It is the most magnetic of all the naturally-occurring minerals on Earth. 

So, statement 3 is correct. 

Magnetite is black or brownish-black with a metallic lustre. So statement 1 is correct. 

Correct option (a) X-rays

Explanation:

E = hf 

So, if you increase the frequency of the wave, you get more energy per photon. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays. 

Correct option (a) 11/3 kg

Explanation:

C + O₂ → CO₂ 

12 g of C gives 44 g of CO₂ 

1 g of C = 11/3 g of CO₂ 

1 kg of C = 11/3 kg CO₂

Correct option (a) more electropositive than iron

Explanation:

The iron or steel object is coated in a thin layer of zinc. This stops oxygen and water reaching the metal underneath - but the zinc also acts as a sacrificial metal. Zinc is more reactive than iron, so it oxidises in preference to the iron object.

Correct option  (a) Oxygen

Explanation:

The atmosphere is composed of ~78% nitrogen and ~21% oxygen, with small amounts of other gases. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.

Correct option  (a) Avogadro's hypothesis

Explanation:

The law is named after Amedeo Avogadro who, in 1811, hypothesized that two given samples of an ideal gas, of the same volume and at the same temperature and pressure, contain the same number of molecules.

Correct option

1. A. have passed

2. D. going

3. C. short 

4. A. by

5. D. desert   

Explanation:

1.  The present perfect tense “have passed” should be used in the blank to indicate that something happened in the past, while implying that the exact time is not important. Hence, option A is the correct answer. 

2. “Happening’ would have been correct if the blank were not succeeded by the preposition “on”. Among the rest, only “going (on)” will form the correct phrasal vern. Thus, option D is the correct answer.

3.  “To be short” of cash or money implies that one has less money than required or has run out of it. Thus, option C is the most appropriate filler. 

4.  The usage of the phrase “side of” indicates that the “by” is the most appropriate preposition to be used. “By the side of” means beside. Thus, option A is the correct filler. 

5. Adversity refers to hard times. With respect to the context of the sentence, true friends will not leave alone/ desert their friends in bad times. Thus, option D is the most appropriate choice. The other options do not fit the context of the passage. 

Correct option (A) It proposed that the Indian magistrates would try Europeans in criminal cases.

Explanation:

The Ilbert Bill was a bill introduced in 1883 during the Viceroyship of the Marquess of Ripon, which was written by Sir Courtenay Peregrine Ilbert (The law member of the Viceroy's Council). According to the said Act, Indian judges could try a European accused.

Correct option B. Bahadur Shah II

Explanation:

The Sanyasis and Fakirs revolted against British from 1763 to 1800 AD because of the prohibition that was imposed by the East India Company’s officials on their pilgrimage. The central leadership comprised of rebel council headed by emperor Bahadur Shah Jafar. Though Bahadur Shah Jafar’s wife Jeenat Mahal tried to conspire with English, but she was not the part of central leadership.

Correct option (d) The Attorney General of India

Explanation:

Attorney general has right of audience in all courts within the territory of India. He has also the right to speak and take part in proceedings of both the houses of parliament including joint sittings. However, he cannot vote in parliament. Attorney General has all the powers and privileges that of a member of parliament. But he is not a member of the parliament.

Correct option C. Q R P S

Explanation:

The first part would be the one which states what the scientists point out. So, Q is the first part. R and P must follow as they imply that the aftermath has reached its peak of the sunspot activity. S, thus comes in the end. Thus the correct sequence after rearrangement is QRPS and option C is the correct answer

Correct option

1. A. is

2. B. against

3. B. disappointing

4. B. to have been born

5. B. her words  

Explanation:

1.The usage of ‘looks’ indicates that the sentence is in the present tense. Thus, the auxiliary ‘is’ should be used. 

2. Since the words “insured” and “theft” have been mentioned, the correct preposition would be “against”. You insure an asset against any mishap. Thus, option B is correct. 

3. We require an adjective to indicate the kind of result. Thus, the noun “disappointment” can be eliminated. “Disappointed” is incorrect as it can only be used in the context of people, but here a “result” is being talked about. “To disappoint” will convey the sense that the purpose of the result was to disappoint, which is not the case here. Hence “disappointing” is the best fit answer.

4.  “By” and “for” are inappropriate prepositions to be followed by the word “lucky”, and “to” must be used. We need the “to be” verb to indicate that the action of taking birth took place, thus, “have been born” is the correct answer. Also, since the sentence is in the passive voice, “have been born”, which is the passive form in past perfect, is correct.

5. To be ‘true to one’s words’ means to act as promised/ said earlier. Thus, option is the correct expression for the blank.

Correct option B. that give it life, an identity, a quality

Explanation:

The error lies in the second part of the sentence. The subject does not agree with the verb here. Since the subject “attention” is singular, the verb should be “gives” and not ‘give’.

Correct option D. No error

Explanation:

The sentence has no error and has been correctly structured.
