Glucocorticoids, Adrenaline, Mineralocorticoids, Suprarenal gland.
(A) Mineralocorticoids
(B) Adrenaline
(C) Suprarenal gland
(D) Glucocorticoids
ANS
(C) Suprarenal gland
Here's why:
Glucocorticoids, Mineralocorticoids, and Adrenaline: These are all hormones produced by the outer layer (cortex) of the suprarenal gland. Each has specific functions, like regulating blood sugar and electrolyte balance (corticoids) or acting in fight-or-flight response (adrenaline).
Suprarenal gland: Located above the kidneys, this gland has two distinct parts: the cortex (mentioned above) and the medulla. The medulla produces adrenaline and non-essential hormones like noradrenaline.
Therefore, the suprarenal gland encompasses all the other listed terms as it's the organ that produces those hormones and hormones are its primary function.

(A) Green bonds
(B) Nature bonds
(C) Low Emission bonds
(D) Environment bonds
(A) Green bonds
Here's why:
Green bonds: This is the widely recognized and established term used globally to describe bonds issued specifically to finance projects that have positive environmental and climate-related benefits. It encompasses a variety of projects like renewable energy, clean transportation, green buildings, and pollution control.
Nature bonds: While gaining traction, this term is more specific and often refers to bonds focused on conservation projects or initiatives directly impacting natural ecosystems. It can be considered a type of green bond with a narrower focus.
Low Emission bonds: This term might be used for bonds focusing on projects specifically aimed at reducing greenhouse gas emissions, but it doesn't fully capture the broader range of environmental sustainability goals that green bonds encompass.
Environment bonds: This term lacks the specificity and clarity of "green bonds" and could potentially encompass a wider range of projects not necessarily related to sustainable development.

109. After the Surat Split in 1907, the second split in the Congress took place in 1918 on the
issue of
(A) Lucknow Pact
(B) Montagu Declaration
(C) Election of Mrs. Annie Besant as President of the INC (1917)
(D) Both (B) and (C) above
The second split in the Indian National Congress after the Surat Split of 1907 occurred in 1918 due to (D) Both (B) and (C) above, the Montagu Declaration and the election of Mrs. Annie Besant as President of the INC in 1917.
Here's a breakdown of the reasons:
Montagu Declaration: This declaration by the British government outlined proposals for constitutional reforms in India, including increased representation for Indians in legislative councils. Moderates within the Congress welcomed the reforms, viewing them as a step towards increased self-governance. However, extremists, led by Bal GangadharTilak, criticized the reforms as inadequate and argued for more immediate action towards complete independence.
Election of Mrs. Annie Besant as President: The election of Mrs. Besant, a prominent supporter of home rule and theosophist movement, further deepened the split within the Congress. Her association with the Home Rule movement created tensions with the moderates who advocated for a more gradual approach to achieving self-governance.
Therefore, the combined factors of the differing opinions on the Montagu Declaration and the leadership of Mrs. Besant ultimately led to the second split in the Congress in 1918.
So, remember that both the Montagu Declaration and the election of Mrs. Besant played a crucial role in triggering this significant event in Indian political history.
110. The main source of methane gas in India-
(A) Floriculture gardens
(B) Orchards
(C) Tea gardens
(D) Paddy fields
(D) Paddy fields
Here's why:
Anaerobic conditions: Paddy fields are flooded with water for most of the growing season, creating an anaerobic environment. This lack of oxygen promotes the growth of methanogenic bacteria, which break down organic matter and produce methane as a byproduct.
Widespread cultivation: Paddy is a staple crop in India, cultivated over vast areas across the country. This extensive coverage contributes significantly to the total methane emissions arising from agricultural practices.
Warm climate: The warm tropical climate in India further accelerates the decomposition process and methanogenesis in paddy fields.
While other options like floriculture gardens, orchards, and tea gardens might also emit some methane through similar processes, their contribution is relatively insignificant compared to the widespread impact of paddy fields.
Therefore, remembering that paddy fields are the primary source of methane gas in India adds valuable insight into the country's greenhouse gas emissions and potential agricultural mitigation strategies.

(A) Srirampur
(B) Bansberia
(C) Kulti
(D) Budge Budge
Out of the provided options, the first paper mill in India was established in West Bengal at:
(A) Srirampur
This occurred in the year 1812, though the mill didn't achieve long-term success due to various factors. While other places like Bansberia, Kulti, and Budge Budge later emerged as important centers for paper manufacturing, Srirampur holds the historical significance of hosting the first such mill in India.
Remembering this historical fact adds to your knowledge about the paper industry's origin and development in the country.
113. Where did Chandragupta Il establish his second capital?
(A) Bidisha
(B) Malava
(C) Valabhi
(D) Ujjayini
answer is (D) Ujjayini.
Chandragupta II, also known as Vikramaditya, was the third ruler of the Gupta Empire in India. He expanded the Gupta empire to the western sea coast, a vital area for trade and commerce. As a result, Malwa and Ujjain (Ujjayini), the region's capital, enjoyed prosperity. Chandragupta II may have defeated the Shaka invaders of Ujjain, and placed his son Govindagupta as a viceroy there. As a result, Ujjain might have become a second capital of the Gupta empire, and subsequently, legends about him (as Vikramaditya) might have developed.
The other options are incorrect because:
Bidisha was a city in the Magadha region, which was the traditional capital of the Gupta Empire.
Malava was a region in central India, but it did not have a single capital city.
Valabhi was a city in Gujarat, which was not part of the Gupta empire at the time of Chandragupta II.
114. In India production of dairy products are comparatively low-
(A) Demand for fresh milk is high.
(B) Most people have low purchasing power for dairy products.
(C) Most milch cattle are lean.
(D) All the reasons above
(D) All the reasons above
The production of dairy products in India is comparatively low due to a combination of factors, including high demand for fresh milk, low purchasing power for dairy products among the population, and the fact that many milch cattle are lean. Therefore, option (D) encompasses all the mentioned reasons.
115, Which of the following is not a capital receipt in the government budget?
(A) Loan recoveries
B) Provident fund deposits
(C) PSU disinvestment
(D) Grants
Ans:
(B) Provident fund deposits
Here's why:
Capital receipts: These are inflows that either create liabilities for the government (like borrowing) or reduce its assets (like disinvestment). They don't necessarily generate income immediately but may bring future benefits.
Loan recoveries: When the government recovers loans it has already provided, it increases its assets, making it a capital receipt.
PSU disinvestment: When the government sells off its ownership in public sector undertakings, it also reduces its assets and qualifies as a capital receipt.
Grants: These are non-repayable transfers from other governments or international organizations. They directly increase the government's income and are considered revenue receipts, not capital receipts.
Provident fund deposits: These are employee contributions towards their retirement savings schemes. While the government manages these funds, the ownership ultimately lies with the employees. Therefore, these deposits don't directly increase the government's assets or create liabilities, making them fall outside the category of capital receipts.
Therefore, remembering that provident fund deposits are not seen as capital receipts due to their ownership structure clarifies the distinction between different types of government inflows.
116. Which provision of the fundamental rights is directly related to the exploitation of children?
(A) Article 17
(Β) Article. 19
(С) Article. 23
(D) Article. 24
The provision of the Indian Constitution directly related to the exploitation of children is:
(D) Article 24
Here's why:
Article 17: This article guarantees the right to go against and avoid any restrictions on the right to travel, reside, settle or pursue an occupation in any part of India. While a connection might be drawn to child trafficking or forced movement, it doesn't specifically address exploitation.
Article 19: This article guarantees fundamental freedoms like freedom of speech and expression, association, and movement. Again, while important for protecting children from certain forms of exploitation, it's not the most direct provision.
Article 23: This article prohibits human trafficking and forced labor. While it tackles exploitation in general, it's broader than just children and encompasses all individuals.
Article 24: This article specifically prohibits the employment of children below the age of 14 in any factory or mine or in any other hazardous employment. This directly addresses the issue of child labor and exploitation in various work settings.
117. Who is known as the 'Parrot of India'?
(A) Jimutavahana
(B) Al-Beruni
(C) Ibn-Batutlah
(D) Amir Khasru
The answer is (D) Amir Khasru.
Amir Khusro, a renowned 13th-century poet and musician, is widely known as the "Parrot of India" for his exceptional skills in language and music. He wrote in several languages, including Persian, Hindi, and Urdu, and was known for his beautiful melodies and innovative musical compositions. His talent and versatility earned him the title "Tuti-e-Hind" in Persian, which translates to "Parrot of India."
The other options are not associated with the title "Parrot of India":
(A) Jimutavahana: A renowned jurist and philosopher, but not particularly known for literary or musical prowess.
(B) Al-Beruni: A prominent 11th-century scholar and polymath, but not connected to the nickname "Parrot of India."
(C) Ibn-Batutlah: A famous 14th-century explorer and travel writer, not known for literary or musical contributions.
Therefore, remembering that Amir Khusro earned the nickname "Parrot of India" due to his remarkable talents in language and music adds to your knowledge of Indian cultural figures and their historical significance.

119. NEAT 3.0 is a platform associated with which Union Ministry of India?
(A) Ministry of Education
(B) Ministry of Health and Family Welfare
(C) Ministry of Commerce and Industry
(D) Ministry of Corporate Affairs
Ans
(A) Ministry of Education of India.
Here's why:
NEAT 3.0 is an initiative launched by the Ministry of Education to provide access to high-quality ed-tech solutions and courses to students across India.
It operates under the guidance of the All India Council for Technical Education (AICTE), which falls under the administrative domain of the Ministry of Education.
The Minister of Education, Dharmendra Pradhan, himself officially launched NEAT 3.0 in October 2021.
Therefore, remembering that NEAT 3.0 belongs to the Ministry of Education adds to your knowledge about government initiatives in the education sector and their respective administrative bodies.
120. Which of the following diseases is autosomal?
(A) Haemophilia
(B) Thalassemia
(C) Colourblindness
(D) All of the above
The answer is (D) All of the above.
These three diseases are all autosomal genetic disorders, meaning the defective gene responsible for the disease is located on one of the 22 autosomal chromosomes (chromosomes 1-22, not the sex chromosomes).
Here's a breakdown of each disease:
Haemophilia: A blood clotting disorder caused by mutations in genes on the X chromosome, making it an X-linked recessive disorder, not autosomal.
Thalassemia: A blood disorder affecting hemoglobin production due to mutations in genes on chromosome 11, making it an autosomal recessive disorder.
Colourblindness: A visual impairment caused by mutations in genes on the X chromosome (red-green colour blindness) or chromosome 7 (blue-yellow colour blindness), making it both X-linked and autosomal recessive depending on the type.
Therefore, while haemophilia is not autosomal, both thalassemia and colourblindness can be inherited through autosomal recessive patterns. So, considering all three options, the correct answer is indeed (D) All of the above.
Remember, understanding the inheritance patterns of different diseases is crucial for genetic counseling and medical interventions.
121. In India the main textile fibre crop is
(A) Jule
(B) Cotton
(C) Flax
(A) Til
The main textile fibre crop in India is:
(B) Cotton
Here's why:
Extensive cultivation: Cotton occupies a significant area in India's agricultural landscape, contributing to around 25% of the global cotton production.
Versatility: Cotton fibers are widely used in textile manufacturing for producing diverse garments, ranging from apparel to bedsheets and towels.
Economic importance: The cotton industry forms a vital part of India's economy, generating employment for millions and contributing to exports.
Historical significance: Cotton has been cultivated in India for centuries, playing a major role in the country's cultural heritage and textile traditions.
While India also cultivates other fibre crops like jute (A), flax (C), and til (D), their production and economic impact are far lower compared to cotton. Jute, for example, finds specific applications in packaging materials and coarse fabrics, while flax and til have limited uses in the textile industry.

Promoting innovation and adoption of Fin-Tech solutions in the Indian financial system.
Regulating and overseeing the Fin-Tech sector to ensure financial stability and consumer protection.
Engaging with stakeholders in the Fin-Tech ecosystem to develop a conducive regulatory environment.
While artificial intelligence, data science, and digital currency play a role in Fin-Tech, they would not represent the entire scope of the newly established department.
Therefore, remembering that the Reserve Bank of India established a dedicated department for Fin-Tech in 2022 expands your knowledge about the central bank's efforts in regulating and facilitating this evolving sector.
125. A Public Service Commission was established in India for the first time by
(A) The Indian Council Act, 1982
(B) The Act of 1909
(C) The Government of India Act, 1919
(D) The Government of India Act, 1935
ANS
(D) The Government of India Act, 1935.
While the concept of a Public Service Commission (PSC) was discussed earlier, a statutory PSC wasn't established in India until the passage of the Government of India Act, 1935. Here's a breakdown of the options:
(A) The Indian Council Act, 1982: This act revamped the composition and functioning of the central PSC but didn't establish it.
(B) The Act of 1909: This could refer to various acts of 1909, none of which established a national PSC in India.
(C) The Government of India Act, 1919: This act laid the groundwork for a PSC by mentioning its future establishment but didn't actually create it.

126. A bird is sitting in a wire cage hanging from the spring balance. Let the reading of the spring balance be W_1. If the bird flies about inside the cage, the reading of the spring balance becomes W_2. Which of the following is true?
(A) W_1 > W_2
(B) W_1< W_2
(C) W_1 = W_2
(D) W_1 = 1/W_2
When the bird is sitting in the cage, the spring balance measures the combined weight of the bird and the cage, W_1. When the bird flies inside the cage, it creates an upward force against the cage due to its flapping wings. This upward force partially cancels out the bird's downward weight.
Therefore, the reading of the spring balance will decrease, meaning:
(A) W_1 > W_2 is the correct answer.
Here's the reasoning:
W_1 = weight of bird + weight of cage
When the bird flies, it creates an upward force (F) which partially cancels its weight
New reading on the spring balance = (weight of bird - F) + weight of cage
Since F is positive and directed upwards, it reduces the overall weight measured by the spring balance.
Therefore, W_2 (reading with bird flying) will be less than W_1 (reading with bird sitting).
Remember, in situations like this where one force counteracts another, the resulting force or weight decreases compared to the initial value.
127. Who was the first historical emperor of India?
(A) Dhanananda
(B) Chandragupta Mourya
(C) Bimbisara
(D) Bindusara
(B) Chandragupta Maurya
Here's why:
Chandragupta Maurya (321-297 BCE) established the Mauryan Empire, which unified a vast majority of the Indian subcontinent under one administration. He is credited with overthrowing the Nanda dynasty and laying the foundation for a powerful and influential empire.
Dhanananda (4th century BCE), the last ruler of the Nanda dynasty, ruled over a significant portion of northern India but didn't unify the entire subcontinent. While powerful, his empire lacked the territorial extent and centralized administration defining a unified imperial entity.
Bimbisara (544-491 BCE) and Bindusara (297-272 BCE) were crucial figures in the Maurya dynasty's rise to power. However, Bimbisara ruled over Magadha, a powerful kingdom but not encompassing the entire subcontinent. Bindusara expanded the Maurya Empire but inherited its foundation from Chandragupta Maurya and is not generally considered the "first emperor" due to the established legacy of his father.
128. Name the Chalukya king who defeatedHarshavardana.
(C) Mangalesh
(D) Kirtivarmana
(A) Pulakeshin I
(B) Pulakeshin II
(B) Pulakeshin II: He defeated Harshavardhana in a battle around 618 CE on the banks of the Narmada River. This clash helped establish the Chalukya dynasty as a major power in South India.
So the correct answer is (B).

131. In the world, by cattle rearing. India ranks
(A) first
(B) fifth
(C) fourth
(D) seventh
India actually ranks (A) first in the world by cattle rearing!
Here are some facts to support this:
India has the largest dairy herd in the world, with over 304 million cattle as of 2020.
It contributes significantly to global milk production, standing at over 112.5 million tonnes in 2009-2010.
India is also the largest exporter of buffalo meat globally and a major exporter of other livestock products.
Therefore, while other countries like China, Brazil, and the United States also have sizeable cattle populations, India significantly outpaces them in terms of overall numbers and dairy production.
Remember, India's agricultural landscape and its emphasis on dairy products play a crucial role in its ranking as the leader in cattle rearing on a global scale.

*P_n=5040, find n.
(A) 10
(B) 12
(C) 20
(D) 16
5040 can be factored as 2^4 3^2 5 * 7.
Now, we can analyze the options:
(A) 10: P_10 = 10 9 8 ... 2 = 10! (factorial of 10), which contains higher powers of 2 and 5 than 5040. So, it's not a match.
(B) 12: P_12 = 12 11 10 ... 2 = 12!, which also contains higher powers of 2 and 5 than 5040. Not a match.
(C) 20: P_20 = 20 19 18 ... 2 = 20!, even more excessive powers of 2 and 5. Not a match.
(D) 16: P_16 = 16 15 14 ... 2 = 16!, which has a higher power of 2 than 5040. Not a match.
None of the given options directly result in 5040. However, we can notice that P_7 = 7 6 5 4 3 * 2 = 5040.
Therefore, even though it's not listed as an option, the correct value of n is n = 7.

(A) Ministry of Commerce and Industry
The pilot phase of The Open Network for Digital Commerce (ONDC) is indeed associated with the Ministry of Commerce and Industry. They launched the initiative in April 2022 with the aim of promoting an open and transparent e-commerce ecosystem in India.
While the other ministries listed might play supportive roles in various aspects of the project, the Ministry of Commerce and Industry holds the primary responsibility for driving the vision and implementation of ONDC.
Therefore, remembering the association between the Ministry of Commerce and Industry and ONDC strengthens your understanding of the government's efforts in developing a more inclusive and competitive e-commerce landscape in India.
136. Which of the following reproductions is found in plants alone?
(A) Vegetative reproduction
(B) Asexual reproduction
(C) Sexual reproduction
(D) Parthenogenesis
(D) Parthenogenesis
While all the options involve reproduction in plants, the specific answer depends on the exact meaning you're looking for:
Vegetative reproduction: This occurs in both plants and some animals (like starfish) through fragmentation, budding, or other means not involving gametes. So, it's not unique to plants.
Asexual reproduction: This is a broader term encompassing both vegetative and parthenogenesis. So, it wouldn't be the precise answer.
Sexual reproduction: This involves the fusion of gametes from two different individuals, generally absent in vegetative reproduction and parthenogenesis. However, some plants utilize cross-pollination, while others can self-pollinate, meaning both options exist in the plant kingdom.
Parthenogenesis: This specific type of reproduction involves the development of an embryo from an unfertilized egg cell. While some animals like certain invertebrates use this method, it's found in many plant species like dandelions, lilies, and orchids.
137. Who built the Adina Mosque of Pandua?
