Q332. Given below are two statements regarding the ‘Socialist’ nature of the Indian State: Statement I: The Indian brand of socialism is a ‘democratic socialism’ and not a ‘communistic socialism’.

This model allows both the public and private sectors to contribute to the nation’s economic development.
Q333. Which of the following best demonstrates the concept of ‘desertification’?

Overgrazing, deforestation, and improper irrigation techniques can deplete soil nutrients and vegetation, leading to the expansion of desert conditions into new areas.

Q337. Which of the following is NOT a recognized characteristic of the Indus script?
Explanation
The Harappan script is not alphabetical; it does not consist of a small set of letters representing sounds. Instead, it is pictographic and logo-syllabic, featuring hundreds of distinct signs.

Explanation
Indian secularism is characterized by a positive concept where the state maintains a principled distance from religion but gives equal respect and support to all religions.

The Mojave Desert in North America, the Kalahari Desert in Africa, and the Great Sandy Desert in Australia are all classified as hot deserts, typically located in subtropical zones. In contrast, the Patagonian Desert in South America is a cold desert. Its higher latitude and the rain shadow effect of the Andes Mountains create a cold, arid environment distinct from the others.
