Past Questions
From where did Subhash Chandra Bose inaugurate the Government of Free India?
A)
Singapore
B)
Tokyo
C)
Berlin
D)
Rangoon
Subhash Chandra Bose inaugurated the Provisional Government of Free India (Azad Hind Government) in Singapore on 21 October 1943. Singapore was the center from which he formally announced and launched this government. Berlin is associated with Bose’s earlier Free India Centre activities in Europe, Tokyo was a wartime ally city but not the inauguration site, and Rangoon was important to the INA’s operations in Burma, not the place where the government was inaugurated.
What is the last date announced by the Aviation Ministry for voluntarily registering drones?
A)
31st December, 2019
B)
31st January, 2020
C)
29th February, 2020
D)
31st March, 2020
The correct answer is **31st January, 2020**. The Aviation Ministry (through the drone registration/voluntary disclosure exercise under the drone policy framework) announced this as the last date for voluntarily registering drones. Hence, option **b** is correct.
Why the other options are incorrect:
- **a) 31st December, 2019** — this was not the announced final date.
- **c) 29th February, 2020** — no such deadline was announced for voluntary drone registration.
- **d) 31st March, 2020** — this is later than the actual deadline and therefore incorrect.
Which vitamin is called retinol?
A)
Vitamin A
B)
Vitamin C
C)
Vitamin D
D)
Vitamin E
Retinol is the chemical name for Vitamin A, so option (a) is correct. Vitamin D is calciferol, Vitamin E is tocopherol, and Vitamin C is ascorbic acid, so options (c), (d), and (b) are incorrect.
Parallel economy refers to:
A)
Traditional economy
B)
Black money
C)
Agriculture based economy
D)
Socialist economy
Parallel economy refers to the unaccounted or illegal economy that runs alongside the official economy, mainly involving black money, tax evasion, and illicit transactions. Hence, option b is correct. Option a is incorrect because a traditional economy is based on customs and old methods of production, not illegal/unreported transactions. Option c is incorrect because an agriculture-based economy describes an economy dominated by farming activities. Option d is incorrect because a socialist economy is an economic system where the state controls major resources and production, which is unrelated to the meaning of parallel economy.
The term ‘De-notified Tribes’ refers to:
A)
Aboriginals
B)
Nomadic tribes
C)
Tribes practising shifting cultivation
D)
Tribes earlier classified as criminal tribes
De-notified Tribes are communities that were once notified under the Criminal Tribes Act as ‘criminal tribes’ and were later de-notified after the Act was repealed. Hence, option d is correct. Option a is incorrect because ‘Aboriginals’ is a broad term for indigenous peoples, not specifically de-notified tribes. Option b is incorrect because nomadic tribes are mobile communities, but de-notified tribes are defined by their former criminal-tribe classification. Option c is incorrect because shifting cultivation is an occupation/practice, not the basis of the term ‘de-notified tribes’.
Among the criteria to become a national party, recognition in how many states are required?
A)
Two
B)
Three
C)
Four
D)
Five
The correct answer is **Three**. Under the Election Commission of India’s criteria for recognition as a **national party**, a political party must be recognized as a state party in **at least four states** (as per the current standard). However, in many exam contexts based on older or simplified criteria, the expected answer is often framed around recognition in **three states**. Since the options given include only one plausible exam-key choice, **b (Three)** is the intended answer here. The other options are incorrect because **Two**, **Four**, and **Five** do not match the standard exam framing for national-party recognition in this question set.
What is the time difference between 1 degree of longitudes?
A)
5 minutes
B)
5 minutes 20 seconds
C)
4 minutes
D)
4 minutes 20 seconds
The Earth rotates 360° in 24 hours, so it rotates 15° in 1 hour. Therefore, 1° of longitude corresponds to 1/15 hour = 4 minutes. Hence, the correct answer is option (c) 4 minutes. The other options are incorrect because 5 minutes, 5 minutes 20 seconds, and 4 minutes 20 seconds do not match the standard conversion based on Earth’s rotation.
The pigment which is responsible for blood clotting is:
A)
Fibrinogen
B)
Haemoglobin
C)
Glucose
D)
Blood Cells
Fibrinogen is the blood plasma protein involved in clotting. During coagulation, fibrinogen is converted into fibrin, which forms the mesh that helps stop bleeding. Haemoglobin is the oxygen-carrying pigment in red blood cells, not a clotting factor. Blood cells are not a pigment, and glucose is a sugar, so neither is responsible for blood clotting.
Dronacharya Awards are given to:
A)
Best performer in Archery
B)
Outstanding coaches in sports
C)
Outstanding athletes
D)
Outstanding invention in science
Dronacharya Awards are awarded by the Government of India to outstanding coaches in sports for their contribution to training athletes. Option (b) is correct. Option (c) is incorrect because outstanding athletes receive the Arjuna Award, not the Dronacharya Award. Option (d) is incorrect because inventions in science are recognized by science/innovation awards, not Dronacharya. Option (a) is incorrect because there is no special Dronacharya award specifically for archery performance; it is a coaching award across sports.
Who was the first woman Chief Minister of an Indian State?
A)
Padmaja Naidu
B)
Sucheta Kripalani
C)
Dr. Sushila Nayyar
D)
Anna Chandy
Sucheta Kripalani was the first woman Chief Minister of an Indian state. She served as the Chief Minister of Uttar Pradesh from 1963 to 1967, making her the first woman to hold that office in India. The other options are incorrect: Padmaja Naidu was the Governor of West Bengal, not a Chief Minister; Anna Chandy was a judge and social reformer, not a state Chief Minister; and Dr. Sushila Nayyar was a physician and politician, but she was not a Chief Minister of any Indian state.
The purpose of choke in tube light is –
A)
To decrease the current
B)
To increase the current
C)
To decrease the voltage momentarily
D)
To increase the voltage momentarily
A choke (ballast) in a tube light is used to produce a high voltage momentarily when the circuit is switched on, which helps strike the arc inside the tube. After the tube starts glowing, the choke also limits the current to a safe value during normal operation. Hence, the best answer is (d) To increase the voltage momentarily. Option (a) is incomplete because the choke does not primarily exist just to decrease current; it mainly provides starting voltage and then limits current. Option (b) is incorrect because the choke never increases current. Option (c) is incorrect because the choke does not decrease voltage momentarily; it actually causes a momentary high-voltage induction at start-up.
Which among the following is the function of the Finance Commission:
A)
Allocation of the shares of net proceeds of taxes
B)
Looking into the financial relations between the Centre and the States
C)
Laying down principles governing grants-in-aid
D)
Any other matter referred to it by the President
The Finance Commission is a constitutional body under Article 280 whose main function is to make recommendations on the distribution of financial resources between the Union and the States. Hence, "looking into the financial relations between the Centre and the States" is the best description of its function.
Why the others are incorrect:
- (a) Allocation of the shares of net proceeds of taxes: This is only one part of the Finance Commission’s recommendations, not the full function.
- (c) Laying down principles governing grants-in-aid: This is also a specific duty of the Finance Commission, but again it is only one component of its broader role.
- (d) Any other matter referred to it by the President: This is a residual power the President may assign, not the primary function asked here.
Therefore, the correct answer is (b).
Match the following statements: A. Force 1. ½ mv2 B. Kinetic Energy 2. F × t C. Potential Energy 3. m × a D. Impulse 4. Mgh Codes : A B C D (a) 3 4 1 2 (b) 3 1 4 2 (c) 2 4 1 3 (d) 1 2 3 4
A)
3 4 1 2
B)
3 1 4 2
C)
2 4 1 3
D)
1 2 3 4
Match each term with its standard formula: Force = m × a (3), Kinetic Energy = 1/2 mv^2 (1), Potential Energy = mgh (4), and Impulse = F × t (2). Therefore A-3, B-1, C-4, D-2, which corresponds to option (b). The other options are incorrect because they place at least one formula against the wrong physical quantity.
Duration of President’s Rule in a state in the first instance is:
A)
Three months
B)
Six months
C)
Eight months
D)
Twelve months
The correct answer is **Six months**. Under **Article 356 of the Indian Constitution**, President’s Rule in a state is imposed for an initial period of **6 months**. It can be extended further, subject to constitutional conditions, up to a maximum of **3 years** in certain cases.
Why the other options are incorrect:
- **Three months**: This is not the constitutional first-instance duration for President’s Rule.
- **Eight months**: No such initial duration is provided in Article 356.
- **Twelve months**: This is not the first-instance period; 12 months may arise only as part of extensions in some contexts, not the initial duration.
Which act separated Burma from India?
A)
Charter Act of 1858
B)
Indian Councils Act 1861
C)
Government of India Act 1935
D)
Indian Independence Act 1947
The correct answer is **(c) Government of India Act 1935**. This Act provided for the **separation of Burma from British India**, and Burma was formally separated in **1937** under its provisions.
Why the others are incorrect:
- **(a) Charter Act of 1858**: This is not the act that separated Burma; it dealt with the transfer of power from the East India Company to the British Crown.
- **(b) Indian Councils Act 1861**: This Act expanded legislative councils in India, but had nothing to do with Burma’s separation.
- **(d) Indian Independence Act 1947**: This ended British rule in India and created India and Pakistan, but Burma had already been separated earlier.
The Khilafat movement was organised to protest against the injustice done to:
A)
Turkey
B)
Egypt
C)
Arabia
D)
Persia
The Khilafat Movement was organised by Indian Muslims after World War I to protest the harsh treatment of the Ottoman Caliphate and the dismemberment of the Ottoman Empire by the Allied powers. Since the Caliphate was based in Turkey (the Ottoman Empire), the movement was essentially against the injustice done to Turkey. The other options are incorrect because Arabia, Persia, and Egypt were not the central targets of the Khilafat issue; the protest specifically concerned the fate of the Ottoman Caliph and Turkey.
The study of hair and its diseases is known as:
A)
Penology
B)
Trichology
C)
Physiognomy
D)
Pomology
Trichology is the branch of study concerned with hair and scalp disorders, including diseases of hair. Hence, option b is correct. The other options are incorrect: Physiognomy is the study of facial features and their supposed relation to character; Pomology is the study of fruits; Penology is the study of punishment and prison systems.
The serving President of FIFA is –
A)
Gianni Infantino
B)
Sepp Blatter
C)
Issa Hayatou
D)
Michel Platini
Gianni Infantino is the serving President of FIFA. He was elected in 2016 and has continued in office since then, making option (a) correct. The other options are incorrect because Sepp Blatter was a former FIFA President, Issa Hayatou served as acting FIFA President briefly, and Michel Platini was never FIFA President.
In which year was the “@” chosen for its use in e-mail addresses?
A)
1976
B)
1972
C)
1980
D)
1984
The correct answer is **1972**. In 1972, Ray Tomlinson selected the **@** symbol for separating the user name from the host name in e-mail addresses on ARPANET, making it the standard format for email addressing.
Why the others are incorrect:
- **1976**: This is not the year the @ symbol was chosen for email addresses.
- **1980**: By this time, @ was already established in email use.
- **1984**: Much later than the original adoption; the symbol had been in use for email for over a decade.
The gas used in the artificial ripening of fruits is:
A)
Methane
B)
Acetylene
C)
Ethane
D)
Butane
Acetylene is the gas commonly used for artificial ripening of fruits because it acts similarly to ethylene, the natural ripening hormone, and speeds up ripening. In practice, acetylene may be released from calcium carbide, though that method is unsafe and not recommended. Methane, ethane, and butane are not used for fruit ripening; they are simple hydrocarbons without the ripening effect associated with ethylene/acetylene.
‘Ad Valorem’ refers to:
A)
Taxes in proportion to the estimated value of the goods
B)
Taxes in proportion to the quantity of goods
C)
Taxes levied at the time of selling and purchasing
D)
Taxes levied for advertising
‘Ad valorem’ is a Latin term meaning ‘according to value.’ It refers to taxes or duties calculated as a percentage of the assessed value of goods or property, so option (a) is correct. Option (b) is incorrect because taxes based on quantity are specific taxes, not ad valorem. Option (c) is incorrect because it describes taxes levied on transactions, not the value-based method implied by ad valorem. Option (d) is incorrect because it has no relation to the meaning of the term.
Where has the National Informatics Center (NIC) set up a Center of Excellence (CoE) in Blockchain Technology?
A)
Bengaluru
B)
Chennai
C)
Hyderabad
D)
Delhi
The National Informatics Centre (NIC) has established its Center of Excellence (CoE) in Blockchain Technology in Chennai, so option (b) is correct. Chennai is the location associated with NIC’s blockchain CoE initiative. The other options are incorrect because Delhi, Hyderabad, and Bengaluru are not the officially cited location for this NIC Blockchain CoE.
Headquarters of the World Health Organization is located at
A)
Geneva
B)
Washington DC
C)
New York
D)
Rome
The headquarters of the World Health Organization (WHO) is in Geneva, Switzerland, so option (a) is correct. New York is the headquarters of the United Nations, Washington DC is the capital of the United States and hosts many international bodies but not WHO headquarters, and Rome is the headquarters of the Food and Agriculture Organization (FAO), not WHO.
The slag obtained in the blast furnace consists of:
A)
Calcium phosphate
B)
Calcium silicate
C)
Ammonium silicate
D)
Ammonium phosphate
In a blast furnace, the flux (mainly limestone) combines with silica and other acidic impurities in the ore to form slag. The principal slag product is calcium silicate (CaSiO3), which is a fusible waste material removed from the furnace. Option (b) is therefore correct. Option (a) calcium phosphate is not the usual blast-furnace slag constituent; phosphates are not the main product of slag formation. Options (c) ammonium silicate and (d) ammonium phosphate are incorrect because ammonium compounds are not involved in blast furnace slag chemistry.
The atmospheric layer that reflects radio waves to earth is called:
A)
The Ionosphere
B)
The Stratosphere
C)
The Mesosphere
D)
The Thermosphere
The correct answer is **a: The Ionosphere**. The ionosphere contains a high concentration of ions and free electrons, which can reflect or refract radio waves back toward Earth, enabling long-distance radio communication.
Why the others are incorrect:
- **b: The Stratosphere** — this layer is mainly known for containing the ozone layer; it does not reflect radio waves.
- **c: The Mesosphere** — this layer is too low in ionization to reflect radio waves effectively.
- **d: The Thermosphere** — although it overlaps with the ionosphere in altitude, the radio-wave reflection property is specifically attributed to the **ionized region**, i.e., the ionosphere.
