25 February : Daily Current Affairs Quiz

Answer: Option D - Access Now

Explanation:

• The report "Emboldened Offenders, Endangered Communities: Internet Shutdowns in 2024" is published by Access Now, a global digital rights organization advocating for internet freedom.
• It highlights that 296 internet shutdowns occurred worldwide in 2024, the highest recorded in any year.
• India accounted for 84 shutdowns (28%), affecting 16 states and union territories, while Myanmar experienced the most shutdowns (85), including those imposed by external entities and armed groups.

Answer: Option B - European Union (EU)

Explanation:

• The General Data Protection Regulation (GDPR) is a data privacy law enacted by the European Union (EU) in 2016 and enforced from May 25, 2018.
• It strengthens user control over personal data, mandates strict data protection measures, and imposes heavy penalties for non-compliance.
• GDPR applies to all organizations processing EU residents' data, even if based outside the EU, setting a global benchmark for data privacy regulations.

Answer: Option A - A framework suggesting that basic constituents of matter are tiny oscillating loops.

Explanation:

• The theory proposes that fundamental particles are not point-like but tiny, vibrating loops of energy.
• Different vibration modes correspond to different particles, potentially unifying quantum mechanics and gravity.
• It requires extra spatial dimensions beyond the familiar four.
• Unlike the Standard Model, which treats particles as zero-dimensional, this framework offers a possible explanation for all fundamental forces, including gravity, making it a leading candidate for a Theory of Everything.

Answer: Option A - General Relativity and Quantum Mechanics

Explanation:

• The Quantum Nature of Gravity seeks to unify General Relativity, which describes gravity at macroscopic scales, with Quantum Mechanics, which governs subatomic particles.
• Current theories like String Theory and Loop Quantum Gravity attempt this unification.
• A successful quantum gravity theory would explain gravitational interactions at the quantum level, resolving inconsistencies between these fundamental frameworks.

Answer: Option B - Quantum Mechanics

Explanation:

• Superposition and entanglement are fundamental principles of quantum mechanics. Superposition states that a quantum system can exist in multiple states simultaneously until measured.
• Entanglement describes a phenomenon where particles remain connected, influencing each other instantaneously, regardless of distance.
• These principles enable advancements in quantum computing, cryptography, and communication.
• Unlike classical mechanics, where states are definite, quantum mechanics allows probabilistic and interconnected behaviors of particles.
