Detailed Explanation

Correct Answer

βœ“ Option (c) is correct. New York City was the first to attain 'megacity' status in 1950.

πŸ“– Core Anchor Concept

A megacity is defined as an urban area with a population exceeding 10 million. The rapid urbanization post-World War II contributed significantly to this demographic shift.

πŸ“œ Detailed Breakdown & Chronology

  • Before 1950, urban areas were more modestly populated, with cities like London and Paris having populations below 10 million.
  • New York City reached a population estimate of over 10 million by mid-20th century, making it the world's first megacity.
  • This milestone marked a significant demographic trend, as global urbanization started to accelerate during the latter half of the 20th century.

πŸ” Option Analysis

  • A: London - Reached peak populations post-New York but remained under 10 million until later decades.
  • B: Paris - Similar to London, its growth did not surpass 10 million until much later.
  • D: Washington - Historically smaller compared to the specified cities and far from the megacity threshold.

⚑ Chronology Trick / Polity Mnemonic

Remember the timeline: New York (1950), London (1971), Tokyo (1959), and finally, Mumbai (1990s) to visualize global urban growth.

Question 2 of 3 NDA MCQ

Which one of the following countries is called the 'country of winds' ?

Detailed Explanation

Correct Answer

βœ“ Option (c) is correct. Denmark is known as the 'country of winds' due to its geographical features.

πŸ“– Core Anchor Concept

Denmark's nickname 'country of winds' is attributed to its flat landscape and coastal location, making it prone to strong winds. This geography affects not only its climate but also its energy policies, heavily investing in wind energy.

πŸ“œ Detailed Breakdown & Chronology

- **Geographical Landscape**: Denmark's highest point, Mollehoj, is just 170.86 m, contributing to minimal barriers against wind. - **Climate Influence**: The country's maritime climate results in variable weather influenced by the North Sea. - **Wind Energy Initiatives**: Denmark was a pioneer in wind energy, with substantial investments since the 1970s, becoming a global leader in renewable energy sources.

πŸ” Option Analysis

- **A: India**: Known for diverse climates but not specifically associated with winds. - **B: China**: Has varied landscapes and climates, not particularly noted for wind. - **C: Denmark**: Correct, emphasizes wind’s impact. - **D: Germany**: Also utilizes wind energy but is not termed 'country of winds'.

⚑ Chronology Trick / Polity Mnemonic

Remember: "Danish Winds" as a mnemonic connects Denmark's identity with its windiness.
