1. India has more arable area than China.
- Correct: India’s arable land area (156 million hectares) is indeed larger than China’s (119 million hectares).
2. The proportion of irrigated area is more in India as compared to China.
- Correct: India’s proportion of irrigated area is 48%, which is higher than China’s 41%.
3. The average productivity per hectare in Indian agriculture is higher than that in China.
- Incorrect: Agricultural productivity in China is significantly higher than that of India, by 50–100%, due to better agricultural practices, technology, and infrastructure.
Conclusion
- Correct Statements: 1 and 2 are correct. (Only two)

The idea of time travel—moving forward or backward through time—has intrigued scientists, philosophers, and storytellers for generations. Here’s a look at its possibilities and challenges from a more approachable perspective:
1. Traveling to the Future: Possible but Limited
Physics shows us that traveling into the future is theoretically possible and already observed in small ways. This idea comes from Einstein’s Theory of Relativity:
• Speed and Time Dilation:
If you move at extremely high speeds, close to the speed of light, time slows down for you compared to someone who remains stationary. For example, an astronaut traveling on a near-light-speed spaceship might age much slower than people on Earth. When they return, they’ll find themselves in the future.
• Gravity and Time:
Strong gravity, like near a black hole, also slows down time. If you stayed near a black hole for a while and then returned to Earth, you would have experienced less time than those far from the black hole.
Real-World Proof: Scientists have tested this concept with atomic clocks on fast-moving planes and satellites. The clocks show tiny differences in time—evidence that time dilation is real.
So, traveling to the future isn’t science fiction—it’s part of how the universe works. The challenge is creating technology that lets us move fast enough or survive extreme gravitational forces.
2. Traveling to the Past: More Complicated
Traveling to the past is far more difficult, both scientifically and logically, though some theories hint at possibilities:
• Wormholes:
Wormholes are like tunnels connecting two points in spacetime. If such tunnels exist—and could be stabilized—they might allow
