Step 1: Understanding the Concept:
These questions cover diverse topics from the history of architecture and mass media to the classification of sports and heritage management.
Step 2: Detailed Explanation:
(1) Characteristics of Islamic Architecture:
Islamic architecture in India (Indo-Islamic style) merged Persian and Indian elements. Key features include:
- Domes and Arches: Large central domes and pointed arches are hallmark features.
- Minarets: Tall towers (like in the Taj Mahal) used for the call to prayer or as decorative pillars.
- Calligraphy and Geometry: Instead of human figures, walls are decorated with Quranic verses and complex geometric patterns.
- Examples: The Qutub Minar (Delhi), Taj Mahal (Agra), and Gol Gumbaz (Vijayapura).
(2) History of Akashvani (All India Radio):
- Origins: Radio began in India with private radio clubs in Mumbai and Kolkata in 1923.
- Government Control: The British government took over in 1927, forming the Indian State Broadcasting Service (ISBS).
- Name Change: In 1936, it was renamed All India Radio (AIR).
- Akashvani: After independence, based on a suggestion by the poet Pandit Narendra Sharma, it was renamed Akashvani in 1956.
- Vividh Bharati: In 1957, the 'Vividh Bharati' service was started for entertainment and music.
(3) Difference between Indoor and Outdoor Games:
- Indoor Games: These are played in a closed environment or a limited space. They generally require more mental strategy than physical exertion. Examples: Chess, Carrom, Ludo, and Table Tennis.
- Outdoor Games: These require large open spaces or grounds. They often involve high physical activity and team coordination. Examples: Cricket, Football, Kabaddi, and Athletics.
(4) Measures for Conservation of Historical Sites:
- Legal Protection: Strict laws must be enforced to prevent vandalism, graffiti, and theft of artifacts.
- Scientific Restoration: Only qualified experts should handle repairs using materials and methods that do not alter the original structure.
- Regulated Zones: Restricting construction or industrial activity within a certain radius of the site to prevent damage from vibrations or pollution.
- Public Awareness: Educating citizens and tourists about the cultural value of the site through signboards and heritage walks.
Step 3: Final Answer:
Islamic architecture is known for its domes and minarets; Akashvani evolved from private clubs to a national broadcaster; games are split between indoor and outdoor based on space; and conservation requires a mix of legal, scientific, and social efforts.
