Correct

Ans: (b)

Explanation:

• The correct answer is B) The Solar Mean Magnetic Field is a measure of the average magnetic field strength across the entire Sun. The Solar Mean Magnetic Field refers to the average magnetic field strength over the entire solar surface. It is calculated by taking measurements of the magnetic field at different points on the Sun and averaging them. This field is important for studying the solar activity and understanding the solar dynamo, which drives the Sun’s magnetic cycles.
• Statement A) is incorrect. The Solar Mean Magnetic Field is not necessarily strongest at the equator. It can vary across different latitudes on the Sun.
• Statement C) is incorrect. While the Solar Mean Magnetic Field is closely related to solar activity, it is not directly responsible for solar flares. Solar flares are intense releases of energy in the form of electromagnetic radiation, which are triggered by complex interactions of magnetic fields in the Sun’s atmosphere.
• Statement D) is incorrect. The Solar Mean Magnetic Field is indeed influenced by solar activity. It varies over time as the Sun undergoes its magnetic cycle, which typically lasts around 11 years. During this cycle, the strength and distribution of the magnetic field change, affecting various solar phenomena.

Ans: (c )

Explanation:

• Context: The Taiwan Strait holds significant importance for India, and India is well-positioned to lead a collaborative effort among Indo-Pacific states to ensure peace in this crucial sea route. The status of Taiwan remains the primary point of contention for China, which blames the US for hindering its goal of reunifying Taiwan with the mainland.
• The Taiwan Strait is a 180-kilometre-wide strait separating the island of Taiwan and continental Asia. The strait is part of the South China Sea and connects to the East China Sea to the north. The narrowest part is 130 km wide.

Correct

Ans: (d)

Explanation:

• Ethical issues related to social morality involve questions of right and wrong in the context of how individuals and society interact. Option D represents an ethical issue because it suggests that discrimination based on race, gender, or religion can be acceptable under certain circumstances. This statement raises concerns about fairness, equality, and the rights of individuals, as discrimination undermines the principles of social justice and equality. Ethical standards generally promote inclusivity, respect, and non-discrimination, making option D an example of a problematic position that conflicts with widely accepted ethical values.

Ans: (d)

Explanation:

• Statement 1 is wrong because as per Calcutta HC decision Aadhar Card is not a proof of citizenship.
• Statement 2 is wrong because UIDAI’s update policy version 2.3 (available on the official website uidai.gov.in) has provisions for deactivation of Aadhaar, which are given below:
• If within 2 years of attaining age 5, the child’s biometrics are not updated in Aadhaar database, his/her Aadhaar number will be deactivated (no authentication permissible). It will be reactivated once biometrics are updated in database.
• If within 2 years of attaining age 15, the child’s biometrics are not updated in Aadhaar database, his/her Aadhaar number will be deactivated (no authentication permissible). It will be reactivated once biometrics are updated in database.
• If Resident has not biometrically authenticated in 5 years, his/her One Time Password (OTP) based authentication services will be deactivated. They will be re-activated once the resident biometrically authenticates.

Correct

Ans: (a)

Explanation:

• S1: While prokaryotes are always unicellular organisms, eukaryotes can be either unicellular or multicellular. For example, most protists are single-celled eukaryotes! Even though prokaryotes do not have a nucleus, they DO contain genetic information.
• S2: Unlike eukaryotes, prokaryotes have no membrane-bound organelles.
• S3: Prokaryotes do not have a nucleus.
• S4: Both prokaryotes and eukaryotes can have either linear or circular DNA. However, the vast majority of prokaryotes have circular DNA, while the vast majority of eukaryotes have linear DNA.

Correct

Ans: (d)

Explanation:

• Kenya shares common borders with five countries namely: Tanzania in the South, Uganda in the West, South Sudan in the North West, Ethiopia in the North and Somalia in the East.
• Context: According to a UN report, over 11 million people have been displaced in East Africa and the Great Lakes region (EHAGL) in 2023.
  • Causes: The displacement is primarily caused by climate shocks such as floods and droughts, as well as conflicts and violence. Countries like Burundi, Ethiopia, Somalia, South Sudan, and Sudan have the highest numbers of internally displaced persons (IDPs).
