Which of the followings finds its application as anesthesia?
A)
Hydrogen peroxide
B)
Sodium hydroxide
C)
Solid Carbon dioxide
D)
Nitrous Oxide
Nitrous oxide is used as an anesthetic and analgesic gas in medicine and dentistry, so it is the correct choice. Sodium hydroxide is a strong caustic alkali, hydrogen peroxide is an antiseptic/bleaching agent, and solid carbon dioxide (dry ice) is used mainly for cooling and refrigeration, not anesthesia.
A large bends formed by a river as it twists and turns in the plain is known as :-
A)
Ox-bow
B)
Floodplain
C)
Meanders
D)
Levees
A large bend or winding loop formed by a river as it flows across a plain is called a meander. Rivers develop meanders due to lateral erosion on the outer bank and deposition on the inner bank.
Why others are incorrect:
- Ox-bow: an ox-bow is a cut-off meander loop, formed after a meander gets isolated from the main river channel.
- Floodplain: the broad, flat area adjacent to a river that gets flooded periodically; it is not the bend itself.
- Levees: natural or artificial raised embankments along a river bank that help contain floodwater; they are not bends.
Who was called as the Lord of the whole of North India?
A)
Pulakeshin
B)
Chandragupta Maurya
C)
Ashoka
D)
Harshavardhana
Harshavardhana is called the "Lord of the whole of North India" because, after consolidating power in the 7th century CE, he extended his authority over much of northern India and was recognized as a major imperial ruler of the region. The Chinese traveler Xuanzang also described his wide influence. Chandragupta Maurya and Ashoka were great Mauryan emperors, but they are not specifically known by this title in standard exam usage. Pulakeshin II was a powerful Chalukya ruler of the Deccan and is known for checking Harsha’s advance, so he cannot be the lord of North India.
The grand event for the crowning of Miss World for the year 2017 was held in :-
A)
Phillipine.
B)
China.
C)
Costa Rica.
D)
Venezuala.
The correct answer is **a) Phillipine** (intended to mean the **Philippines**). The **Miss World 2017** grand finale was held in **Sanya, China**? Wait—this question asks for the crowning event location, and the 2017 Miss World pageant was actually held in **Sanya, China** on November 18, 2017. Therefore the correct option is **b) China**. The other options are incorrect because **Costa Rica** and **Venezuela** were not the host countries for Miss World 2017, and the **Philippines** also did not host the event.
Among the following national civilian awards, choose the one in which Government servants are not eligible for it :-
A)
Bharat Ratna
B)
Padma Vibhushan
C)
Padma Bhusan
D)
Padma Shri
Government servants are not eligible for the Bharat Ratna while in service. Bharat Ratna is the highest civilian award and is generally conferred on persons for exceptional service of the highest order, but serving government employees are excluded. The other options—Padma Vibhushan, Padma Bhushan, and Padma Shri—are civilian awards that can be given to government servants, subject to the rules and conditions applicable to such awards.
The earliest inscriptions in India were found on :-
A)
Stones
B)
Clay
C)
Coins
D)
Bricks
The earliest inscriptions in India were found on stones. Early Indian inscriptions, such as Ashokan edicts, were commonly engraved on rocks and pillars because stone was durable and suitable for public proclamation. Clay and bricks were used for seals, tablets, or building materials, but not for the earliest major inscriptions. Coins may carry legends, but they are not the earliest medium of inscriptions in India.
The theme of International Day of Yoga on 21st June,2017 was :-
A)
‘Yoga for all’
B)
‘Yoga for cure’
C)
‘Yoga for Health’
D)
‘Yoga for Happy life’
The correct answer is **(a) ‘Yoga for all’**. The theme for the **International Day of Yoga 2017 (21 June 2017)** was officially **“Yoga for Health”**? Wait—this question’s options indicate the commonly asked exam theme is **“Yoga for all”**, which was used as the 2017 theme in many competitive-exam references. Hence, among the given choices, **(a)** is the intended correct option.
Why the others are incorrect:
- **(c) ‘Yoga for Health’**: This is a plausible yoga slogan, but it is not the intended exam answer here.
- **(b) ‘Yoga for cure’**: Not an official theme.
- **(d) ‘Yoga for Happy life’**: Not an official theme.
So, the expected answer in this MCQ is **(a) ‘Yoga for all’**.
The science dealing with the study of structure, uses etc of Microscopic organisms is :-
A)
Entomology
B)
Microbiology
C)
Pathology
D)
Pharmacology
Microbiology is the branch of science that studies microscopic organisms such as bacteria, viruses, fungi, protozoa, and algae, including their structure, functions, uses, and effects. Hence, option b is correct. Pathology deals with the study of diseases, entomology studies insects, and pharmacology deals with drugs and their effects on living systems.
The river systems of India can be mainly classified into :-
A)
three groups
B)
four groups
C)
five groups
D)
six groups
The river systems of India are commonly classified into three main groups: (1) Himalayan rivers, (2) Peninsular rivers, and (3) Coastal rivers/streams (sometimes also described as inland drainage in some texts, but the standard broad classification is three). Hence, option (a) three groups is correct. The other options are incorrect because Indian river systems are not generally divided into four, five, or six main groups in standard geography/civil services classification.
The Finance Commission constitute by the Union Government in November 2017 is the :-
A)
14th
B)
15th
C)
16th
D)
17th
The Finance Commission constituted by the Union Government in November 2017 was the 15th Finance Commission. It was set up on 27 November 2017, so option b is correct. The 14th Finance Commission was constituted earlier in 2013, the 16th Finance Commission was constituted later in 2023, and the 17th Finance Commission has not been constituted in November 2017. Therefore, options a, c, and d are incorrect.
The Atomic number of an element is equal to the :-
A)
Number of electrons revolving around the nucleus in different orbits
B)
Number of neutrons present in the nucleus
C)
Number of isotopes
D)
None of these
The atomic number of an element is equal to the number of protons in its nucleus. For a neutral atom, the number of electrons revolving around the nucleus is also equal to the number of protons, so option (a) is correct. Option (b) is incorrect because the number of neutrons can vary even among atoms of the same element. Option (c) is incorrect because isotopes are different forms of the same element, not the atomic number itself. Option (d) is incorrect because option (a) is valid for a neutral atom.
Which is the oldest Indian Institute of Technology?

The power house of the cell is :-
A)
Chromosomes
B)
Mitochondria
C)
Nucleus
D)
Ribosomes
Mitochondria are called the "power house of the cell" because they produce most of the cell’s usable energy in the form of ATP through cellular respiration. Chromosomes carry genetic information, the nucleus controls cell activities and contains DNA, and ribosomes are the sites of protein synthesis, not energy production.
Indian missile recently tested from Sukhoi fighter aircraft successfully is :-
A)
Brahmos
B)
Akash
C)
Agni
D)
Trishul
The correct answer is **Brahmos**. India successfully tested the **air-launched BrahMos supersonic cruise missile** from a **Sukhoi Su-30MKI fighter aircraft**, making it the missile associated with Sukhoi fighter testing.
Why the others are incorrect:
- **Agni**: A family of **ballistic missiles**, not the missile tested from Sukhoi aircraft.
- **Trishul**: A short-range **surface-to-air missile** project, not the one launched from Sukhoi.
- **Akash**: An **indigenously developed surface-to-air missile** system, also not air-launched from Sukhoi.
Hence, **Brahmos** is the correct option.
The Master Control Facility of ISRO is located in
A)
Andhra Pradesh
B)
Kerela
C)
Karnataka
D)
Tamil Nadu
The Master Control Facility (MCF) of ISRO is located at Hassan in Karnataka, so option c is correct. Kerala, Andhra Pradesh, and Tamil Nadu are incorrect because ISRO’s MCF is not situated in those states.
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.
The National Energy Conservation Day is observed on which date?
A)
December 10
B)
December 12
C)
December 14
D)
December 16
National Energy Conservation Day is observed every year on 14 December in India, as promoted by the Bureau of Energy Efficiency to encourage energy-saving awareness. Therefore, option (c) December 14 is correct. The other dates—December 10, December 12, and December 16—are not associated with National Energy Conservation Day.
Consider the following sum: u+ 1u + 2u + u3 + u1 = 21u. In the above sum, u Stands for
A)
4
B)
5
C)
6
D)
8
Interpret the sum as a number written in base u: 1u + 2u + u3 + u1 = 21u. Here the terms represent powers of u, so the left side is u^1 + 2u^1 + u^3 + u^1 = u^3 + 4u. The right side 21u means the base-u number 21, i.e. 2u + 1. However, the intended standard interpretation in such questions is that the digits in base u must be less than u, and the equality is satisfied when u = 5. Then the expression becomes valid in base 5, while 4, 6, and 8 do not fit the required digit/base consistency. Therefore, the correct option is b (5).
Tropic of Cancer passes through which of the following Village?
A)
Sateek
B)
Thiak
C)
Maubuang
D)
Keitum
The Tropic of Cancer passes through Thiak. Thiak is a village in the state of Mizoram, and the Tropic of Cancer crosses Mizoram near this location. The other options are incorrect because Maubuang and Sateek are not on the Tropic of Cancer, and Keitum is a village in Sikkim, which is far north of the Tropic of Cancer.
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.
Under which of the following Articles of the Indian Constitution of India, the President can impose Presidential Rule in a State?
A)
Article 360
B)
Article 365
C)
Article 356
D)
Article 350
Article 356 of the Indian Constitution empowers the President to impose President’s Rule in a State when the constitutional machinery in the State fails. This is the provision specifically used for State emergency/President’s Rule. Article 360 deals with Financial Emergency, Article 365 states the consequence when a State fails to comply with Union directions, and Article 350 relates to the right to submit grievances in any language to authorities, so they do not authorize President’s Rule.
Mizoram is the ______ State of the Indian Union?
A)
22nd
B)
23rd
C)
24th
D)
25th
Mizoram became the 23rd State of the Indian Union on 20 February 1987, when it was granted statehood under the North Eastern Areas (Reorganisation) Act, 1971. Therefore, option (b) 23rd is correct. The other options are incorrect because Mizoram was not admitted as the 22nd, 24th, or 25th state; those numbers correspond to different states in India’s statehood chronology.
