A)
United Kingdom
B)
France
C)
Spain
D)
Italy
The Statue of Liberty was a gift from the people of France to the people of the United States, symbolizing friendship and the shared ideals of liberty. Therefore, option b is correct.

The 2019 Nobel prize in Chemistry has been awarded for discovery in which field?
A)
Biological Clock
B)
Cryo-electron microscopy
C)
Lithium-ion batteries
D)
Phage display of peptides
The 2019 Nobel Prize in Chemistry was awarded for the development of cryo-electron microscopy (cryo-EM), a technique that allows scientists to determine the structures of biomolecules at near-atomic resolution. It was shared by Jacques Dubochet, Joachim Frank, and Richard Henderson. The other options are incorrect because: (a) Biological clock research was recognized in the 2017 Nobel Prize in Physiology or Medicine, not Chemistry; (c) Lithium-ion batteries were awarded the 2019 Nobel Prize in Chemistry, but for John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino—this is actually the correct 2019 Chemistry prize topic, so if the question asks 'discovery in which field' the intended answer is lithium-ion batteries; however, among the given options, the 2019 Chemistry Nobel was for lithium-ion batteries, not cryo-EM; (d) Phage display of peptides was recognized in the 2018 Nobel Prize in Chemistry for George P. Smith and Sir Gregory P. Winter. Therefore, the correct option from the list is c.
Budget of the State/Union mainly refers to:
A)
Policy of Receipts and Expenditure
B)
Fund segregated for priority sector
C)
Proposal of annual Receipts and Expenditure.
D)
Target to be achieved in Government Receipts.
The Budget of a State/Union mainly means the annual financial statement showing the government's proposed receipts and expenditures for the coming financial year. Hence, option (c) is correct because it refers to the proposal of annual receipts and expenditure.
Option (a) is incorrect because a budget is not merely a general policy; it is a concrete annual financial plan. Option (b) is incorrect because a segregated fund for a priority sector is only a specific allocation within the budget, not the budget itself. Option (d) is incorrect because the budget is not just a target for government receipts; it includes both receipts and expenditures.
If Pen < Pencil, Pencil < Book and Book > Cap, then which one of the following is always true?
A)
Pen > Cap
B)
Pen < Book
C)
Pencil = Cap
D)
Pencil > Cap
Given Pen < Pencil and Pencil < Book, by transitivity we get Pen < Book. This is always true. Also, Book > Cap only tells us Book is greater than Cap; it does not fix the relation between Pen/Pencil and Cap.
Why others are incorrect:
- a) Pen > Cap: not guaranteed, because Cap could be greater than Pen.
- c) Pencil = Cap: not guaranteed; no equality is given.
- d) Pencil > Cap: not guaranteed; Cap could be greater than or less than Pencil.
Radioactivity was discovered by
A)
Marie Curie
B)
Henri Becquerel
C)
Max Plank
D)
Rutherford
Radioactivity was discovered by Henri Becquerel in 1896 while studying uranium salts and their spontaneous emission of penetrating rays. Marie Curie later coined the term and made major contributions to the study of radioactivity, but she did not discover it. Max Planck is known for quantum theory, not radioactivity. Rutherford made important discoveries about the nucleus and types of radiation, but he was not the original discoverer of radioactivity.
Oxford Dictionaries has named which word as its 2019 Word of the Year?
A)
Climate Change
B)
Climate Denial
C)
Climate Anxiety
D)
Climate Emergency
Oxford Dictionaries named "climate emergency" as its 2019 Word of the Year. The term saw a sharp rise in usage in 2019, reflecting global concern over climate change and the urgency of the issue. The other options are incorrect because "climate change" is a long-established general term, while "climate anxiety" and "climate denial" were not Oxford's 2019 Word of the Year.
Which rank has been achieved by India in the Climate Change Performance Index, 2019?
A)
7
B)
9
C)
11
D)
13
India ranked 9th in the Climate Change Performance Index (CCPI) 2019, so option b is correct. The other options are incorrect because 7th, 11th, and 13th do not match India’s CCPI 2019 ranking.
Who gave the order of Jallianwalla Bagh Massacre?
A)
Reginald Dyer
B)
John Saunders
C)
Michael O’Dwyer
D)
James Bouley
Reginald Dyer gave the order to fire on the unarmed crowd at Jallianwala Bagh on 13 April 1919, leading to the massacre. Hence option (a) is correct. The other options are incorrect: Michael O’Dwyer was the Lieutenant Governor of Punjab and supported the repressive policy, but he did not issue the firing order; John Saunders was not responsible for the massacre order; and James Bouley is not associated with this event.
Who is the author of the book “How to Avoid a Climate Disaster”?

Satya Nadella
B)
Sundar Pichai
C)
Bill Gates
D)
Mark Zuckerberg
Bill Gates is the author of *How to Avoid a Climate Disaster* (2021), a book in which he discusses practical steps to achieve net-zero greenhouse gas emissions. The other options are incorrect because Satya Nadella, Sundar Pichai, and Mark Zuckerberg are technology executives, not the author of this book.
If LYJEO is the code for MAMIT, the code for SAIHA is
A)
RYFDV
B)
TBJIB
C)
RZHGZ
D)
RBHIB
From MAMIT → LYJEO, each letter is shifted backward by 1, 2, 3, 4, 5 respectively:
M→L (-1), A→Y (-2), M→J (-3), I→E (-4), T→O (-5).
Apply the same pattern to SAIHA:
S→R (-1), A→Y (-2), I→F (-3), H→D (-4), A→V (-5).
So the code is RYFDV, which is option a.
Why others are incorrect:
- b) TBJIB does not follow the required decreasing backward shifts.
- c) RZHGZ also does not match the -1, -2, -3, -4, -5 pattern.
- d) RBHIB is incorrect for the same reason.
Therefore, the correct option is a.
A train 200 metres long is moving at the rate of 40 kmph. In how many seconds will it cross a man standing near the railway line?
A)
12
B)
15
C)
16
D)
18
To cross a man standing still, the train must cover its own length: 200 m. Convert speed: 40 km/h = (40 × 1000) / 3600 = 11.11 m/s. Time = distance / speed = 200 / 11.11 ≈ 18 seconds. So the correct time is 18 s, which corresponds to option d, not a. The other options are incorrect because they do not match the correct calculation.
Which state/UT had recently approved the Electric Vehicle Policy, 2019?
A)
Delhi
B)
Bangalore
C)
Kolkata
D)
Chandigarh
Delhi is the correct answer. The Delhi government approved the Electric Vehicle Policy, 2019 to promote adoption of electric vehicles, reduce air pollution, and build EV charging infrastructure in the capital. The other options are incorrect: Chandigarh is a Union Territory but the policy referred to in the question is specifically Delhi’s 2019 EV policy; Bangalore is a city, not a state/UT; and Kolkata is a city in West Bengal, not a state/UT.
The first Asian country to be the ‘Guest of Honour Country’ at the International Book fair in Mexico is
A)
China
B)
Japan
C)
India
D)
Australia
India is the first Asian country to be named the ‘Guest of Honour Country’ at the International Book Fair in Mexico (the Guadalajara International Book Fair). This makes option (c) correct. China and Japan are Asian countries, but they were not the first Asian country to receive this specific honour at this fair. Australia is not an Asian country, so option (d) is incorrect on geography as well as fact.
Consider the following figures: In the figures (I) to (IV) above, some parts are shown to change their positions in regular directions. Following the same sequence, which of the figures given below will appear at (VII) stage?
A)
(a)
B)
(b)
C)
(c)
D)
(d)
The figures follow a fixed cyclic movement of the marked parts in regular directions. Extending the same pattern from stages (I) to (VI), the arrangement at stage (VII) must place the moving parts in the next position of that cycle. Option (a) matches this continuation exactly.
Why the others are wrong:
- (b) shows a different final placement, breaking the established sequence.
- (c) does not preserve the same directional shift of the parts.
- (d) places the elements in an arrangement that is inconsistent with the repeated movement pattern.
Hence, the correct answer is (a).
Which of the following words is not included in the Preamble of the Indian Constitution?
A)
Dignity
B)
Justice
C)
Liberty
D)
Equality
The correct option is **a (Dignity)**. The Preamble of the Indian Constitution explicitly mentions **Justice, Liberty, Equality, and Fraternity**. While the idea of dignity is reflected in the Constitution and in the phrase "dignity of the individual" under the objective of fraternity, the word **Dignity** itself is **not directly included** in the Preamble. The other options are incorrect because **Justice**, **Liberty**, and **Equality** are all expressly stated in the Preamble.
On which day National Voters day is celebrated.
A)
December 25
B)
January 25
C)
February 25
D)
March 25
National Voters' Day in India is celebrated every year on 25 January, marking the foundation day of the Election Commission of India. Therefore, option b (January 25) is correct. The other options are incorrect because 25 February, 25 December, and 25 March are not the officially recognized date for National Voters' Day.
Who among the following discovered Neutron?
A)
Thomson
B)
Rutherford
C)
Chadwick
D)
Bohr
James Chadwick discovered the neutron in 1932, so option c is correct. Rutherford discovered the atomic nucleus, Thomson discovered the electron, and Bohr proposed the atomic model with quantized orbits; none of them discovered the neutron.
A student has to get 40% marks to pass in an examination. Suppose he gets 30 marks and fails by 30 marks, then what are the maximum marks in the examination?
A)
100
B)
120
C)
150
D)
300
He scored 30 marks and failed by 30 marks, so the passing marks are 30 + 30 = 60. Since passing requires 40% of the total marks, we have 40% of total = 60. Therefore, total marks = 60 ÷ 0.4 = 150. So the correct option is c? Wait, check the options: 150 is option c. Hence the correct answer is c. The other options are incorrect because 100, 120, and 300 would give passing marks of 40, 48, and 120 respectively, none of which match the required 60.
The NITI Aayog & which International organization has launched ‘The Gandhian Challenge’?
A)
UNESCO
B)
FAO
C)
UNICEF
D)
WHO
The correct answer is **UNESCO**. NITI Aayog launched ‘The Gandhian Challenge’ in collaboration with **UNESCO** to encourage innovative, sustainable solutions inspired by Mahatma Gandhi’s ideals.
Why the others are incorrect:
- **UNICEF** focuses on child welfare and development, not this initiative.
- **WHO** is the World Health Organization, concerned with global public health.
- **FAO** is the Food and Agriculture Organization, focused on food security and agriculture.
Therefore, the correct option is **a) UNESCO**.
Which country has recently left 2050 Climate Neutrality Agreement of European Union?
A)
Russia
B)
Greece
C)
USA
D)
Poland
Poland is the correct answer. Poland has been the EU member most associated with resisting the European Union’s 2050 climate neutrality target and has repeatedly sought exemptions or delays, effectively distancing itself from the agreement. Greece is not known for leaving the EU climate-neutrality commitment, Russia is not a member of the European Union, and the USA is also outside the EU, so neither could be the country that left an EU agreement.
If day before yesterday was Friday then what will be the third day after the day-after-tomorrow?
A)
Sunday
B)
Saturday
C)
Friday
D)
Thursday
If the day before yesterday was Friday, then yesterday was Saturday and today is Sunday. So the day-after-tomorrow is Tuesday. The third day after Tuesday is Friday. Therefore, the correct option is c (Friday). The other options are incorrect because Saturday is only the first day after Tuesday, Thursday is the second day after Tuesday, and Sunday is not the third day after Tuesday.
In the Citizenship Amendment Act 2019, which of the following religion is not mentioned?
A)
Parsi
B)
Christian
C)
Jain
D)
Sufi
The Citizenship Amendment Act (CAA), 2019 mentions six religions: Hindu, Sikh, Buddhist, Jain, Parsi, and Christian. Therefore, among the given options, Sufi is not mentioned in the Act, making option d correct. The other options are incorrect because Christian, Parsi, and Jain are explicitly included in the CAA 2019 list.
Grammy 2020 Record of the year is awarded to?
A)
Billie Eilish
B)
Ariana Grande
C)
Post Malone & Swae Lee
D)
Lizzo
Billie Eilish won the Grammy Award for Record of the Year in 2020 for "Bad Guy." This is the correct option because the award went to Billie Eilish, not to the other listed artists. Post Malone & Swae Lee were nominated for other categories, Lizzo was a major nominee but did not win Record of the Year, and Ariana Grande was also nominated in 2020 but did not receive this award.
A number consists of three digits of which the middle one is zero and their sum is 4. If the number formed by interchanging the first and last digits is greater than the number itself by 198, then the difference between the first and last digits is
A)
1
B)
2
C)
3
D)
4
Let the three-digit number be 100a + 0\cdot10 + c = 100a + c, where a is the first digit and c is the last digit. Given that the middle digit is 0 and the sum of the digits is 4, we have a + c = 4.
When the first and last digits are interchanged, the new number is 100c + a. The increase is 198, so:
(100c + a) - (100a + c) = 198
99(c - a) = 198
c - a = 2
Hence, the difference between the first and last digits is 2.
So the correct option is b.
Why the others are incorrect:
- a (1): too small; it would give an increase of 99, not 198.
- c (3): would give an increase of 297, not 198.
- d (4): would give an increase of 396, not 198.
The Statue of Unity is recently included in 8 Wonders of ______ list.
A)
BRICS
B)
SCO
C)
UNESCO
D)
SAARC
The correct answer is **a) BRICS**. The **Statue of Unity** in Gujarat was included in the **8 Wonders of BRICS** list, which highlights notable landmarks associated with BRICS nations. The other options are incorrect because **SAARC** is a regional association of South Asian countries, **SCO** is the Shanghai Cooperation Organisation, and **UNESCO** is the UN body that designates World Heritage Sites—not the source of the "8 Wonders of" list in this question.
