✅ Correct Answer: C. Pregnancy & Child birth

📚 Explanation: An obstetrician is a medical doctor who specializes in pregnancy, childbirth, and the period immediately following delivery. They are trained to manage the health of both the mother and the fetus throughout the entire gestation process.

This field of medicine often involves surgical procedures like C-sections and managing complications during labor. It is distinct from pediatrics, which focuses on children, or neurology, which deals with the nervous system.

✅ Correct Answer: C. Cruelty

📚 Explanation: The word 'atrocity' refers to an extremely wicked or cruel act, typically one involving physical violence or great injury. It is often used in the context of war crimes or humanitarian disasters where innocent people suffer greatly.

Therefore, 'cruelty' is the most accurate synonym among the given options. Other terms like 'solidarity' or 'punctuality' have entirely different meanings related to unity and timing.

✅ Correct Answer: A. for

📚 Explanation: In English grammar, when mentioning an employer or a specific organization you belong to, the preposition 'for' is the standard choice. It indicates the entity that pays for your services or provides your employment.

While 'at' or 'in' might sometimes be used in casual speech to describe a location, 'works for' is the most appropriate way to describe a professional relationship with a company. This is a common prepositional rule in competitive exams.

✅ Correct Answer: C. Rehearsal

📚 Explanation: The word 'rehearsal' refers to a practice session for a play, concert, or other public performance. The correct spelling is R-E-H-E-A-R-S-A-L, which comes from the verb 'rehearse'.

Many students make mistakes by omitting the 'a' or changing the 's' to a 'c'. Remembering that it contains the word 'hear' can be a useful trick to secure the correct spelling in your mind.

✅ Correct Answer: C. Adjective

📚 Explanation: The word 'Adjective' itself is a noun because it is the name of a specific grammatical category or part of speech. It serves as a label for words that describe or modify other nouns.

However, in many logic or vocabulary tests, this question is a trick to see if you can identify the grammatical function of the word provided in the prompt. In this specific mock set, 'Adjective' is identified by its own label.

✅ Correct Answer: C. over

📚 Explanation: The noun 'control' is followed by the preposition 'over' when referring to power or influence exerted on a person, feeling, or situation. Having "no control over" something means you are unable to restrain or manage it.

Common mistakes include using 'on' or 'with', but in formal English, 'control over her temper' is the only correct idiomatic expression.

✅ Correct Answer: B. Secret

📚 Explanation: The term 'covert' describes something that is not openly acknowledged or displayed; it essentially means hidden or disguised. It is frequently used in military or intelligence contexts to describe missions done in private.

Because 'secret' also refers to information or actions kept hidden from others, it serves as a direct synonym. On the other hand, 'honest' or 'desert' provide no logical connection to the meaning of being hidden.

✅ Correct Answer: A. painting

📚 Explanation: A gerund is the '-ing' form of a verb that functions as a noun in a sentence. After verbs like 'like', 'love', or 'enjoy', we typically use a gerund to describe the general activity being discussed.

In this sentence, 'painting' acts as the object of the verb 'like', representing the hobby or action. While 'to paint' is an infinitive that can also follow 'like', the specific instruction here asks for a correct gerund.

✅ Correct Answer: A. Claim

📚 Explanation: The word 'forgo' means to give up or do without something voluntarily, especially something pleasant or valuable. It implies a sense of surrender or choosing to skip an opportunity.

The direct opposite or antonym is 'claim', which means to assert one's right to something or to take possession of it. This contrast highlights the difference between yielding a right and demanding it.

✅ Correct Answer: A. Humanitarian

📚 Explanation: A 'philanthropist' is a person who seeks to promote the welfare of others, typically by donating generous amounts of money to good causes. The word comes from the Greek roots 'philo' (love) and 'anthropos' (man).

This makes 'humanitarian' the most suitable definition, as both terms refer to the active desire to help humanity. It is the opposite of a 'misanthrope', who is a hater of mankind.

✅ Correct Answer: D. Compound

📚 Explanation: A compound sentence consists of two or more independent clauses joined by a coordinating conjunction. In the phrase 'Do or Die', the word 'or' connects two separate commands that could stand alone as complete thoughts.

This structure is used to present a choice between two alternatives. Unlike simple sentences with only one clause, compound sentences allow for more complex logical connections between actions.

✅ Correct Answer: C. Loquacious

📚 Explanation: The word 'loquacious' is used to describe a person who tends to talk a great deal or is extremely talkative. It is a formal adjective derived from the Latin root 'loqui', meaning to speak.

Other options like 'voracious' (extremely hungry) or 'avaricious' (extremely greedy) describe different types of excess. 'Loquacious' specifically targets the behavior of continuous talking.

✅ Correct Answer: C. Hate

📚 Explanation: To 'adore' someone or something means to love and respect them deeply or to worship them. It represents a very strong positive emotion and high regard.

The word 'hate' serves as the perfect antonym because it represents the extreme opposite emotion of intense dislike or hostility. 'Ignore' is a neutral action and does not capture the emotional contrast required.

✅ Correct Answer: B. Alumni

📚 Explanation: 'Alumni' is the plural form of the Latin word 'alumnus', referring to a group of people who have graduated from a particular school or university. In English, many Latin-origin words follow unique pluralization rules.

Other options like 'index' (singular of indices), 'hypothesis' (singular of hypotheses), and 'analysis' (singular of analyses) are all in their singular forms. 'Alumni' is the only plural term in this list.

✅ Correct Answer: B. on

📚 Explanation: When referring to the use of a telecommunications device, the preposition 'on' is used to indicate the medium being used. Phrases like 'on the phone' or 'on the radio' are standard English idioms.

It describes a state of being engaged in a call or activity through that specific device. Using 'at' or 'in' would be grammatically incorrect when describing someone spending time talking through a telephone.

✅ Correct Answer: D. Hermaphrodite

📚 Explanation: A 'hermaphrodite' is an organism that possesses both male and female reproductive organs. In biology, this condition allows some species to produce both types of gametes, either simultaneously or at different stages of life.

This term is the specific scientific one-word substitution for the description provided. Terms like 'masochist' or 'homosexual' refer to psychological traits or sexual orientations, not biological organ structures.

✅ Correct Answer: B. Present Perfect

📚 Explanation: The sentence "I have done my duty" uses the auxiliary verb 'have' followed by the past participle 'done'. This specific structure is the hallmark of the Present Perfect tense in English grammar.

This tense is used to describe an action that happened at an unspecified time in the past but has a result or relevance in the present. It links the completed act of doing the duty to the current moment.

✅ Correct Answer: B. A very mild punishment

📚 Explanation: The idiom 'a slap on the wrist' is used to describe a warning or a punishment that is much less severe than the offense deserves. It implies that the person was let off very easily.

For example, if someone commits a major error but only receives a small fine, it is called a slap on the wrist. It highlights the lack of serious consequences for a wrong action.

✅ Correct Answer: D. about

📚 Explanation: The verb 'worry' is almost always followed by the preposition 'about' when identifying the cause of the anxiety or concern. "Worrying about" something is the standard way to express being troubled by a topic.

Using prepositions like 'to' or 'with' in this context would result in a nonsensical or grammatically broken phrase.

✅ Correct Answer: A. (Q) (P) (R) (S)

📚 Explanation: To form a logical sentence, we start with the qualifying clause "although a great scientist" (Q), followed by the subject and verb "Einstein was" (P). This sets up the contrast for the next part.

The final segments "weak in arithmetic" (R) and "right from his school days" (S) complete the thought. The full sentence reads: "Although a great scientist, Einstein was weak in arithmetic right from his school days."

✅ Correct Answer: D. By whom has the work been done?

📚 Explanation: To convert an active question starting with 'Who' into passive, we change 'Who' to 'By whom'. The present perfect structure 'has done' becomes 'has been done' in the passive voice.

The object 'the work' is placed between the auxiliary 'has' and the participle 'been done'. This follows the standard rules of voice transformation for interrogative sentences.

✅ Correct Answer: B. number

📚 Explanation: The phrase 'in number' is a fixed English idiom used to specify the total count of a group of people or things. It emphasizes the collective size of the group mentioned.

In this sentence, it clarifies that the total count of the brothers including Ram was four. Using 'quantity' is incorrect as that term is usually reserved for inanimate objects or uncountable masses.

✅ Correct Answer: C. of

📚 Explanation: In English, when someone passes away due to a specific disease, the preposition 'of' is the standard choice. For example, one dies 'of' cancer, 'of' malaria, or 'of' dengue.

While 'from' is sometimes used for external causes like hunger or injuries, 'of' is strictly preferred for internal medical conditions in formal grammar.

✅ Correct Answer: C. bear with

📚 Explanation: The phrasal verb 'bear with' means to remain patient or to tolerate someone or something, even if it is difficult or annoying. It is the most accurate substitute for the word 'tolerance'.

For instance, a teacher might ask students to "bear with" a delay. Other variations like 'bear on' (to be relevant) have entirely different meanings and do not fit the context of patience.

✅ Correct Answer: B. see eye to eye

📚 Explanation: The idiom 'see eye to eye' means to be in full agreement with someone on a particular matter. It suggests that both parties have the same viewpoint and have reached a consensus.

Replacing "agreed" with this idiom makes the sentence more expressive. Other options like 'let the cat out of the bag' (to reveal a secret) are completely irrelevant to the idea of agreement.

✅ Correct Answer: A. Singhbhum District

📚 Explanation: The Notuburu iron ore mines are located in the West Singhbhum district of Jharkhand. This region is part of the famous iron ore belt of India, providing high-quality raw materials for the steel industry.

Singhbhum is historically one of the richest mineral zones in the country. It is well-connected to major industrial hubs like Jamshedpur, facilitating easy transport of ore.

✅ Correct Answer: D. Bipin Chandra Pal

📚 Explanation: Aurobindo Ghosh famously described Bipin Chandra Pal as one of the mightiest prophets of nationalism. This was due to Pal's powerful oratory and his role in the 'Lal-Bal-Pal' trio that advocated for 'Purna Swaraj'.

Pal was a key architect of the Swadeshi movement and revolutionary thought in Bengal. His contributions were essential in shifting the Congress toward a more radical political creed.

✅ Correct Answer: B. Periyar E. V. Ramasamy Naicker

📚 Explanation: The Self-Respect Movement was started by E.V. Ramasamy (popularly known as Periyar) in 1925 in Tamil Nadu. The goal was to achieve a society where backward castes have equal human rights and to encourage self-respect among the marginalized.

Periyar strongly criticized the caste system and the dominance of the priestly class. His movement became a cornerstone of modern Dravidian politics and social reform in South India.

✅ Correct Answer: A. Manik Saha

📚 Explanation: Dr. Manik Saha was appointed as the Chief Minister of Tripura in May 2022, succeeding Biplab Kumar Deb. He is a dental surgeon turned politician and a prominent leader of the Bharatiya Janata Party in the state.

He led the party to victory again in the 2023 assembly elections. His appointment was aimed at strengthening the party's image and administration ahead of key polls.

✅ Correct Answer: A. Harishena

📚 Explanation: The Allahabad Prasasti (also known as the Prayag Prashasti) was composed by Harishena, who was the court poet of the Gupta Emperor Samudragupta. It is an inscription engraved on an Ashokan pillar in Allahabad.

The text is written in Sanskrit and provides a detailed account of the military conquests and achievements of Samudragupta. It is one of the most important primary sources for studying the Gupta Empire.

✅ Correct Answer: C. 4 / 5

📚 Explanation: To solve this, convert the fractions to decimals: 3/4 = 0.75 and 5/6 is approximately 0.83. We need a value between these two numbers.

Comparing the options: 2/3 = 0.66 (too small), 1/2 = 0.50 (too small), 9/10 = 0.90 (too big). Only 4/5 = 0.80 falls perfectly in the range between 0.75 and 0.83.

✅ Correct Answer: A. Peripatus

📚 Explanation: Peripatus is known as a 'living fossil' because it has remained virtually unchanged for millions of years. It is a unique organism that serves as a connecting link between annelids (segmented worms) and arthropods (insects).

It possesses features of both groups, such as a thin cuticle and jointed legs. Such organisms are highly valuable to scientists for understanding the evolutionary history of life on Earth.

✅ Correct Answer: B. Ilbari Turks, Khilji, Tughluq, Lodi

📚 Explanation: The Delhi Sultanate consisted of five dynasties in the following chronological order: The Slave Dynasty (Ilbari Turks), the Khiljis, the Tughlaqs, the Sayyids, and finally the Lodis.

This sequence began in 1206 with Qutb-ud-din Aibak and ended in 1526 with the defeat of Ibrahim Lodi. Knowing this timeline is fundamental for understanding medieval Indian history and administration.

✅ Correct Answer: B. India

📚 Explanation: The Indian men's badminton team made history by winning the Thomas Cup for the first time in May 2022. They achieved this feat by defeating the 14-time champions Indonesia 3-0 in the final.

This victory is considered the "1983 World Cup moment" for Indian badminton. It showcased the growing strength and depth of Indian sports on the global stage.

✅ Correct Answer: D. Chlorofluorocarbon

📚 Explanation: Chlorofluorocarbons (CFCs), often known by the brand name Freon, have traditionally been used as refrigerants and coolants in refrigerators and air conditioners. They are chosen for their stability and efficiency in heat exchange.

However, CFCs are major contributors to the depletion of the ozone layer in the atmosphere. Due to environmental concerns, they are now being phased out and replaced by more eco-friendly alternatives.

⚠️ Correct Answer: None of these (Originally Victoria, but event cancelled)

📚 Explanation: The state of Victoria in Australia was originally selected to host the 2026 Commonwealth Games. However, in mid-2023, the Victorian government cancelled its plans to host the event due to a massive increase in estimated costs.

Since the original host withdrew, the 2026 Games faced a period of uncertainty before Glasgow was recently named as the new host. This makes the older mock test key "Victoria" technically outdated but historically relevant to the question's era.

✅ Correct Answer: B. Second Five-Year Plan

📚 Explanation: The Second Five-Year Plan (1956-1961) is popularly known as the 'Mahalanobis Plan'. It was based on the strategy developed by the statistician Prasanta Chandra Mahalanobis, which emphasized heavy industrialization.

The plan focused on the development of basic and capital goods industries, such as iron and steel. This shift aimed to make India a self-reliant and industrially advanced nation.

✅ Correct Answer: D. Malda

📚 Explanation: According to the 2011 Census data, the district of Malda recorded the highest child sex ratio (0-6 age group) in West Bengal. This indicator is crucial for understanding the gender balance and social health of the youngest population.

A higher ratio suggests a more favorable environment for female children compared to other districts. Monitoring these trends helps the government design better welfare programs for girl children.

✅ Correct Answer: C. 101st

📚 Explanation: The legendary filmmaker Satyajit Ray was born on May 2, 1921. Therefore, in the year 2022, his 101st birth anniversary was celebrated across the world by film enthusiasts and cultural organizations.

Ray is India's only Oscar-winning director (Lifetime Achievement) and is famous for masterpieces like the Apu Trilogy. His work continues to influence and inspire filmmakers globally.

✅ Correct Answer: B. GATT

📚 Explanation: The World Trade Organization (WTO) was established on January 1, 1995, as the successor to the General Agreement on Tariffs and Trade (GATT). GATT had been the primary international agreement governing trade since 1948.

The WTO expanded the scope of international trade rules to include services and intellectual property. It is headquartered in Geneva and serves as the global body for regulating trade between nations.

✅ Correct Answer: C. 94

📚 Explanation: The pattern in the sequence is (previous number x 2) + 2. Specifically: (4 x 2) + 2 = 10; (10 x 2) + 2 = 22; (22 x 2) + 2 = 46.

Following this rule, the next term is (46 x 2) + 2, which equals 92 + 2 = 94.

✅ Correct Answer: B. Akbar

📚 Explanation: The Buland Darwaza (Great Gate) was built by the Mughal Emperor Akbar in 1601 at Fatehpur Sikri. It was constructed to commemorate his successful military conquest of Gujarat.

It is the highest gateway in the world and a magnificent example of Mughal architecture. The gate is made of red and buff sandstone and serves as the main entrance to the Jama Masjid at Fatehpur Sikri.

✅ Correct Answer: B. 10

📚 Explanation: This is a series with a complex addition and subtraction pattern: 3 + 5 = 8; 8 - 2 = 6; 6 + 8 = 14. To continue, we look for a repeating or increasing logic.

Following a pattern of +5, -2, +8, if we assume the next step is -4, we get 14 - 4 = 10. Then 10 + 10 = 20. This "add, subtract" logic fits the given sequence of numbers.

✅ Correct Answer: B. Sivasamudram

📚 Explanation: The Sivasamudram Dam, located on the Cauvery river in Karnataka, was primarily built for the generation of hydroelectric power. In 1902, it became one of the first major hydroelectric power stations in Asia.

While other dams like Bhakra Nangal or Krishnaraja Sagar are multipurpose projects that include irrigation, Sivasamudram is historically significant for power production. It supplied electricity to the Kolar Gold Fields.

✅ Correct Answer: D. Cauvery

📚 Explanation: The Mettur Dam is one of the largest and oldest dams in India, built across the Cauvery river in the Salem district of Tamil Nadu. It was completed in 1934 and is a vital source of water for the region.

The dam provides irrigation for a vast area of agricultural land and also generates hydroelectric power. The park and reservoir (Stanley Reservoir) associated with the dam are also major tourist attractions.

✅ Correct Answer: A. 50 years

📚 Explanation: Let the Father be F, Elder son E, and Younger son Y. F = 2E and E - Y = 15, so Y = E - 15. The condition 10 years hence is (F + 10) = 3(Y + 10).

Substituting the values: (2E + 10) = 3(E - 15 + 10) => 2E + 10 = 3E - 15. Solving this gives E = 25. Thus, the father's age is 2 x 25 = 50.

✅ Correct Answer: A. Yamuna, Chambal and Son

📚 Explanation: Tributaries that join a river from the right side (following the direction of the flow) are called right bank tributaries. For the Ganga, the Yamuna is the largest such tributary, which itself is joined by the Chambal.

The Son river also flows from the south and joins the Ganga directly near Patna. Together, these rivers form a significant part of the Ganga's drainage system in Northern India.

✅ Correct Answer: B. Selim

📚 Explanation: Prince Selim (who later became Emperor Jahangir) ordered the assassination of Abul Fazl in 1602. He suspected Abul Fazl of influencing Akbar against him and feared losing his succession to the throne.

✅ Correct Answer: C. Ajmer — Kubbatul Islam

📚 Explanation: The Quwwat-ul-Islam (Kubbatul Islam) mosque was built by Qutb-ud-din Aibak in Delhi, not Ajmer. It is located in the Qutb Minar complex and is the oldest surviving mosque in Northern India.

The famous religious structure in Ajmer built during the same period is the 'Adhai Din Ka Jhonpra'. All other pairs in the options correctly match the medieval monuments with their respective regions.

✅ Correct Answer: D. LNMK

📚 Explanation: The sequence follows a pattern of reversing alphabetical jumps: Z-V-R-L-J. Each first letter moves back by 4 places (Z-4=V, V-4=R, R-4=L, L-4=J).

Looking at the middle letters, they follow a similar consistent backward progression. Applying this pattern to the missing fourth term, we find that the combination LNMK correctly completes the series.

✅ Correct Answer: C. Mitochondria

📚 Explanation: Mitochondria are known as the 'powerhouse of the cell' because they are the primary sites of cellular respiration. They convert nutrients like glucose and oxygen into energy in the form of ATP (Adenosine Triphosphate).

Every living cell requires mitochondria to perform its vital functions. They are unique organelles because they contain their own DNA and can replicate independently within the cell.

✅ Correct Answer: D. elected by an electoral college constituted by members of the two Houses of the Parliament.

📚 Explanation: According to Article 66 of the Indian Constitution, the Vice-President is elected indirectly by an electoral college. This body consists of all members (both elected and nominated) of the Lok Sabha and the Rajya Sabha.

Unlike the Presidential election, members of the state legislatures do not participate in electing the Vice-President. The election is held through a secret ballot using the system of proportional representation.

📚 Explanation: In 1982, the earliest fossil remains of archaic Homo sapiens in India were discovered in Hathnora, situated in the Narmada Valley of Madhya Pradesh. This fossil is popularly known as the 'Narmada Man'.

The discovery provided the first direct evidence of early human presence in the Indian subcontinent during the Middle Pleistocene era. It remains a landmark site for anthropologists and historians studying human evolution in Asia.

✅ Correct Answer: A. 7

📚 Explanation: Let the number of cows be C and hens be H. Total legs L = 4C + 2H. Total heads He = C + H. The problem states L = 2He + 14.

Substituting the variables: 4C + 2H = 2(C + H) + 14. This simplifies to 4C + 2H = 2C + 2H + 14, which means 2C = 14. Therefore, the number of cows is 14/2 = 7.

✅ Correct Answer: C. (d), (c), (a), (b)

📚 Explanation: The correct chronological order is: Megasthenes (Mauryan period, 4th century BC), Fa-Hien (Gupta period, 5th century AD), Xuanzang (Harsha's period, 7th century AD), and I-tsing (late 7th century AD).

These travelers provided invaluable accounts of Indian society, culture, and religion during their respective eras. Their writings are primary sources for historians reconstructing ancient and medieval Indian history.

✅ Correct Answer: B. Gandhiji

📚 Explanation: 'Navjivan' was a weekly newspaper published by Mahatma Gandhi in Gujarati. He used this platform to spread his ideas of non-violence, truth, and rural development among the common people.

He also published an English version called 'Young India'. These newspapers played a vital role in educating the Indian public and mobilizing them for the freedom struggle.

✅ Correct Answer: C. 200 days

📚 Explanation: Total food units = 4000 men x 190 days. Food used in 30 days = 4000 x 30. Remaining food = 4000 x (190 - 30) = 4000 x 160.

After 800 men left, the remaining men are 3200. The number of days the food will last is (4000 x 160) / 3200. This calculation simplifies to (5 x 160) / 4, which equals 200 days.

✅ Correct Answer: A. F-

📚 Explanation: Isoelectronic species are atoms or ions that have the same number of electrons. An Oxygen atom has 8 electrons, so O2- has 10 electrons (8 + 2).

A Fluorine atom has 9 electrons, so the F- ion also has 10 electrons (9 + 1). Therefore, O2- and F- are isoelectronic with each other. This concept is a fundamental part of atomic structure in chemistry.

✅ Correct Answer: C. Securities and Exchange Board of India

📚 Explanation: SEBI stands for the Securities and Exchange Board of India. It was established in 1988 and given statutory powers in 1992 to regulate the Indian securities market.
