Q1. Who was the first Slave King of Delhi Sultanate?
Comprehensive Description
The Delhi Sultanate period began in 1206 CE, and its first ruling dynasty was the Mamluk Dynasty (popularly known as the Slave Dynasty). Qutubuddin Aibak was the founder of this dynasty and the first Muslim ruler of Delhi.
He was called a “Slave King” because he was originally a Turkish slave bought by Sultan Muhammad Ghori. Due to his loyalty, intelligence, and military skills, he rose to become Ghori’s most trusted general and governor. When Ghori died without an heir in 1206, Aibak took control of the Indian territories and declared himself an independent ruler.
Dynastic Timeline of the Sultanate
- Slave/Mamluk Dynasty (1206–1290): Started by Qutubuddin Aibak.
- Khilji Dynasty (1290–1320): Famous for Alauddin Khilji.
- Tughlaq Dynasty (1320–1414): Famous for Muhammad bin Tughlaq.
- Sayyid Dynasty (1414–1451)
- Lodi Dynasty (1451–1526): The final dynasty.
Options Analysis
- A) Iltutmish: He was the son-in-law of Aibak and the third ruler. While he is considered the real consolidator of the Sultanate, he was not the first.
- B) Qutubuddin Aibak: The Correct Answer. He started the slave dynasty and began the construction of the famous Qutub Minar.
- C) Razia Sultan: The daughter of Iltutmish and the first female Muslim ruler of Delhi, but she came later (1236).
- D) Balban: A later powerful Slave king (1266) known for his strict policies of “Blood and Iron.”
Key Points to Remember
- Qutubuddin Aibak was also known as ‘Lakh Baksh’ (giver of lakhs) because of his extreme generosity.
- He ruled for only 4 years and died in 1210 while playing Chaugan (an early form of Polo) after falling off his horse.
Q2. Which is the innermost layer of the Earth?
Comprehensive Description
The Earth is structured like a massive onion, divided into three concentric structural layers based on their chemical composition. The deepest, central, and innermost layer is called the Core (or Crond in Hindi).
The core starts from a depth of about 2,900 km below the Earth’s surface and extends up to the very center of the Earth at roughly 6,371 km. Because it is buried deep under enormous pressure, it is incredibly hot, with temperatures reaching up to 6000°C, similar to the surface of the Sun.
Scientific Breakdown of the Layers
- Crust (0–35 km): The outermost, thinnest rocky shell we live on. Made of SIAL (Silicon and Aluminium).
- Mantle (35–2900 km): The middle layer made of hot, semi-solid rocks. Made of SIMA (Silicon and Magnesium).
- Core (2900–6371 km): The innermost layer. It is made of NIFE (Nickel and Ferrum/Iron).
Options Analysis
- A) Crust: The outermost surface layer, not the inner.
- B) Mantle: The thick middle layer located between the crust and the core.
- C) Core: The Correct Answer. It is divided into a liquid outer core and a solid inner core.
- D) Lithosphere: A functional term that combines the crust and the brittle upper mantle, not an individual inner layer.
Q3. What is the main work of a ‘Patwari’?
Comprehensive Description
In India’s rural administrative setup, a Patwari (also known as a Lekhpal, Kanungo, or Village Accountant in different states) is a vital government official responsible for land management at the village level.
Their primary and most important job is measuring land and maintaining village land records. Each Patwari is responsible for a single village or a small cluster of villages. They keep track of who owns which piece of land, what crops are being grown, and updates map data whenever a field is bought or sold.
Step-by-Step Administrative Hierarchy
- District Collector (DM): The head of the entire district administration.
- Tahsildar: Manages land disputes and revenue at the Taluka/Tehsil level.
- Patwari: The ground-level official directly interacting with farmers in the village.
Options Analysis
- A) Building roads: This is handled by the Public Works Department (PWD) or village Panchayats, not the Patwari.
- B) Measuring land and keeping records: The Correct Answer. They use a long iron chain called a jareeb for measurements.
- C) Fighting wars: Handled by the military forces.
- D) Policing the city: Handled by the police department to maintain law and order.
Real-Life Examples
- Example (Getting a Bank Loan): If a farmer in a village wants to take a crop loan from a bank, the bank will ask for proof of land ownership (known as Khasra or Khatauni). The farmer must go to the local Patwari to get these verified records.
Q4. The world’s highest waterfall is located in which continent?
Comprehensive Description
The world’s highest uninterrupted waterfall is Angel Falls, and it is located in the continent of South America.
Angel Falls drops from a staggering height of 979 meters (with a clear plunge of 807 meters) from the edge of the Auyán-tepui mountain. It is located inside the Canaima National Park in the Bolivar State of Venezuela. The waterfall is so high that before the water even hits the ground, much of it turns into a fine mist due to the strong winds.
Options Analysis
- A) North America: Home to Niagara Falls, which is famous for its massive volume of water but is not the highest.
- B) Africa: Home to Victoria Falls, one of the world’s widest waterfalls.
- C) South America: The Correct Answer. It houses the record-breaking Angel Falls.
- D) Asia: Home to beautiful falls like Jog Falls (India), but not the highest in the world.
Key Points to Remember
- The waterfall was named after Jimmy Angel, an adventurous American pilot who was the first person to fly over the falls in an airplane in 1933.
- The local indigenous name for the falls is Kerepakupai Merú, which means “waterfall of the deepest place.”
Q5. In which year was the first Battle of Panipat fought?
Comprehensive Description
The First Battle of Panipat was fought on April 21, 1526. This historic battle took place near the town of Panipat (in modern-day Haryana) and completely altered the course of Indian history by bringing an end to the Delhi Sultanate and marking the birth of the Mughal Empire.
The battle was fought between the invading forces of Babur (a Timurid ruler from Central Asia) and the massive army of Ibrahim Lodi (the last Sultan of Delhi). Despite being heavily outnumbered, Babur achieved a decisive victory due to his superior war strategies.
Babur’s Secret Weapons
- Gunpowder and Artillery: This was the first time field artillery (cannons) and firearms were used on a large scale in Northern India. The loud sound of the cannons panicked Ibrahim Lodi’s war elephants, causing them to turn around and trample their own soldiers.
- Tulughma Tactics: A strategy of dividing the army into small divisions to surround the enemy from all sides.
Options Analysis
- A) 1526: The Correct Answer. Fought between Babur and Ibrahim Lodi (Birth of Mughal Empire).
- B) 1556: The year of the Second Battle of Panipat, fought between Akbar (led by Bairam Khan) and Hemu.
- C) 1761: The year of the Third Battle of Panipat, fought between the Maratha Empire and the Afghan invader Ahmad Shah Durrani.
- D) 1530: The year Babur died, and his son Humayun took the throne.
