This question is based on the General Theory of Relativity (GTR), proposed by Albert Einstein in 1915. It fundamentally changed our understanding of gravity, space, and time.

Statement-wise Explanation

Statement 1: Light is affected by gravity
✅ Correct
It is one of the key predictions of GTR.
Massive objects like stars and black holes bend the path of light, a phenomenon known as gravitational lensing.
This was experimentally confirmed during the 1919 solar eclipse by Sir Arthur Eddington.

Statement 2: The Universe is constantly expanding
✅ Correct
While Einstein initially believed in a static universe, his equations allowed for expansion or contraction.
The Friedmann–Lemaître–Robertson–Walker (FLRW) solutions to Einstein's equations describe an expanding universe.
Edwin Hubble confirmed this, and the cosmic microwave background radiation later provided further support.
Thus, the expanding universe is a cosmological implication of General Relativity.

Statement 3: Matter warps its surrounding space-time
✅ Correct
This is the central idea of General Relativity.
Massive objects curve the space-time fabric, and this curvature is what we perceive as gravity.
This explains why planets orbit the Sun — they follow curved paths in the warped space-time.

📌Analysis of the Question

The question tests your conceptual clarity of Einstein’s General Theory of Relativity (GTR) — a topic often mentioned in the news (e.g. black holes, gravitational waves).
Whether you can distinguish between direct predictions of GTR vs related but independent cosmological observations.

🎯 Difficulty Level

Moderate to High

🧠Type of Question

Conceptual + Current Affairs-based
Tests basic awareness of trending scientific and technological terms often seen in news or PIB articles.

🎯What it Tests

Your ability to associate terms with their correct domains.
Awareness of interdisciplinary topics: AI, biotechnology, digital tech, particle physics.
Distinguishing between buzzwords and actual context of use.

🧩Difficulty Level

Moderate: Not fact-heavy, but requires updated general awareness.

Dear Aspirant,

If you’re feeling anxious tonight, don’t worry — you’re not alone. Almost everyone feels the same before the exam. It simply means you care — and caring is not a weakness.

But remember: tomorrow’s paper won’t test your perfection — it will test your presence. In that moment, what matters most is how calmly and clearly you face each question. You don’t need to know everything. No one does. You just need to stay composed enough to apply what you do know.

So tonight, take a deep breath. Whatever happens tomorrow, one thing is already certain: you showed up and gave it your best. That alone sets you apart.

Wishing you clarity, calmness, and courage.

Warm regards,
Team PMF IAS
