    The world's second tallest statue in sitting pose of Ramanuja was inaugurated by the Prime Minister of India at Hyderabad recently. Which one of the following statements correctly represents the teachings of Ramanuja?

    1. AThe best means of salvation was devotion.
    2. BVedas are eternal, self-existent and wholly authoritative.
    3. CLogical arguments were essential means for the highest bliss.
    4. DSalvation was to be obtained through meditation.
    Answer and explanation

    Correct answer: A

    Ramanuja believed in qualified non-dualism (Vishishtadvaita), where the individual soul (atman) and God (Brahman) coexist in a qualified oneness.

    Qualified Non-dualism (Vishishtadvaita): This is the core concept in Ramanuja's philosophy. It contrasts with the strict non-dualism (Advaita) of Adi Shankara. While both acknowledge an ultimate reality, Ramanuja argues for a qualified oneness, where the individual soul (atman) and God (Brahman) exist in a dependent relationship.

    God's supremacy: Ramanuja emphasized the concept of a personal God, often identified with Vishnu, who is both immanent (present within the world) and transcendent (beyond the world).

    Path to salvation: Liberation (moksha) is achieved through devotion (bhakti) to God and his grace.

    3. CSangam poems have no reference to warrior ethic.
    4. DSangam literature refers to magical forces as irrational.
    Answer and explanation

    Correct answer: B

    Sangam literature, which dates back to the Sangam period in ancient South India (c. 3rd century BCE to 3rd century CE), does indeed contain references to the social classification of Varna. The poems provide insights into the societal structure of that time, including the division of society into different social groups or Varnas. Therefore, option b is correct.

    Sangam poems often contain references to material culture, including descriptions of trade, agriculture, urban life, and everyday objects.

    Sangam's poems frequently depict warrior ethics, with many poems glorifying valour, bravery, and military prowess.

    Sangam literature includes references to various supernatural or magical forces, but these are typically presented as part of the cultural and religious beliefs of the time rather than being explicitly labelled as irrational.

    2. B2 and 4
    3. C1 and 4
    4. D2 and 3
    Answer and explanation

    Correct answer: A

    Statement 1 is correct. PET fibres can be blended with cotton or wool to improve properties like wrinkle resistance and durability.

    Statement 2 is incorrect. Not all PET containers are suitable for all alcoholic beverages. Some PET can leach chemicals at high temperatures or with certain types of alcohol. It's important to check for specific suitability indicators on the packaging.

    Statement 3 is correct. PET bottles are one of the most commonly recycled plastics. They can be reprocessed into various products like clothing fibres, new bottles, or building materials.

    Statement 4 is incorrect. Incineration of PET, like most plastics, generates greenhouse gas emissions, including carbon dioxide. While PET has a lower emission profile compared to some other plastics, it's still not a zero-emission disposal method.

    Remember: Statements like store any kind of alcoholic beverages are vague & ambiguous, so they ought to be eliminated. Also, incineration of any substance cannot be environment friendly as it would definitely release GHGs. Hence the only Option left is Option A. Therefore, the correct statements are 1 and 3.

    It is a delivery system that uses a low Earth orbit to bypass early warning systems and deliver warheads on targets very quickly.

    FOBS launches a warhead into a low Earth orbit trajectory instead of a full ballistic missile arc.

    These systems are typically designed to detect missiles launched on high ballistic trajectories. A FOBS warhead in a low orbit might be harder to detect until it re-enters the atmosphere for its final approach to the target.

    Due to the orbital path, the time between re-entry and target impact can be shorter compared to a traditional ballistic missile attack.

    With reference to Indian history, consider the following statements: 1. The first Mongol invasion of India happened during the reign of Jalal-ud-din Khalji. 2. During the reign of Ala-ud-din Khalji, one Mongol assault marched up to Delhi and besieged the city. 3. Muhammad-bin-Tughlaq temporarily lost portions of north-west of his kingdom to Mongols. Which of the statements given above is/are correct?

    1. A1 and 2
    2. B2 only
    3. C1 and 3
    4. D3 only
    Answer and explanation

    Correct answer: B

    Statement 1 is Incorrect: The first Mongol invasion of India occurred in 1221 CE under Genghis Khan during the reign of Shamsuddin Iltutmish, not Jalal-ud-din Khalji. Jalal-ud-din Khalji ruled much later, from 1290 to 1296 CE.

    Statement 2 is Correct: During the reign of Ala-ud-din Khalji (1296–1316 CE), the Mongols invaded several times. In 1303 CE, a Mongol army of about 120,000 horsemen led by Targhi marched up to Delhi and besieged the city, forcing Ala-ud-din to take shelter in the Siri Fort.

    Statement 3 is Incorrect: Muhammad-bin-Tughlaq defeated the Mongols (led by Tarmashirin) early in his reign. Instead of losing territory, he took steps to secure the frontier and even planned a 'Khurasan expedition' to mobilize against Mongol territories, though it was later abandoned.

    Consider the following statements: DNA Barcoding can be a tool to: 1. assess the age of a plant or animal. 2. distinguish among species that look alike. 3. identify undesirable animal or plant materials in processed foods. Which of the statements given above is/are correct?

    1. A1 only
    2. B3 only
    3. C1 and 2
    4. D2 and 3
    Answer and explanation

    Correct answer: D

    Statement 1 is incorrect. DNA Barcoding cannot assess the age DNA barcoding primarily focuses on identifying species based on their unique genetic sequences.

    Statement 2 is correct. DNA barcoding is a valuable tool for distinguishing between species that appear similar morphologically. By analyzing short, standardized DNA sequences, scientists can efficiently and accurately identify different species, even if they look very alike.

    Statement 3 is correct. DNA barcoding can be used to identify the origin and composition of food products. This can help detect cases where cheaper or undesirable ingredients (food adulteration) are substituted for the ones listed on the label. For example, it can be used to identify different types of meat in processed foods.

    Therefore, statements 2 and 3 are correct.

    Consider the following pairs: Country - Important reason for being in the news recently 1. Chad – Setting up of permanent military base by China. 2. Guinea – Suspension of Constitution and Government by military 3. Lebanon – Severe and prolonged economic depression 4. Tunisia – Suspension of Parliament by President How many pairs given above are correctly matched?

    1. AOnly one pair
    2. BOnly two pairs
    3. COnly three pairs
    4. DAll four pairs
    Answer and explanation

    Correct answer: C

    Pair 1 is incorrectly matched. China has not established any permanent military base in Chad.

    Pair 2 is correctly matched. Guinean special forces staged a coup, captured President Alpha Conde, replaced governors with the military, and dissolved the constitution and National Assembly.

    Pair 3 is correctly matched. Lebanon has been experiencing a severe and prolonged economic depression since 2019, driven by political instability, inadequate reforms, and systemic corruption. The economic crisis has affected approximately 74% of the population.

    Pair 4 is correctly matched. Tunisian President Kais Saied dissolved the suspended parliament after lawmakers held an online meeting and voted to repeal presidential decrees. He called it a failed coup attempt.

    Consider the following communication technologies: 1. Closed-circuit Television 2. Radio Frequency Identification 3. Wireless Local Area Network Which of the above are considered Short-Range devices/technologies?

    1. A1 and 2 only
    2. B2 and 3 only
    3. C1 and 3 only
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: D

    Out of the listed communication technologies, all three can be considered short-range devices/technologies.

    Closed-Circuit Television (CCTV): CCTV systems primarily use cables or wireless connections with a limited range, typically within a building or a designated area.

    Radio Frequency Identification (RFID): RFID uses radio waves to identify objects. The reading range of RFID tags depends on the specific technology but generally falls within the short-range category, from a few centimetres to a few meters.

    Wireless Local Area Network (WLAN): WLANs, commonly known as Wi-Fi networks, typically operate within a range of tens of meters indoors and up to hundreds of meters outdoors depending on factors like signal strength and frequency band. While the range might be slightly larger than the others on this list, WLANs still fall under the short-range classification compared to technologies like cellular networks or satellite communication.

    Which one of the following statements best describes the role of B cells and T cells in the human body?

    1. AThey protect the body from environmental allergens.
    2. BThey alleviate the body's pain and inflammation.
    3. CThey act as immunosuppressants in the body.
    4. DThey protect the body from the diseases caused by pathogens.
    Answer and explanation

    Correct answer: D

    B cells and T cells are both key components of the human immune system, which defend the body against harmful invaders like viruses, bacteria, and parasites.

    B cells produce antibodies that can specifically target and neutralize pathogens.

    T cells help orchestrate the immune response by directly attacking infected cells or by stimulating other immune cells.
