    The confluence of what two rivers is shown in the above picture?

    Answer: Rio Negro and Amazon aka (Rio Solimões)

    The Meeting of Waters in Brazil is where the dark Rio Negro meets the pale, sediment-rich Rio Solimões (Amazon River) but flows side by side for kilometres without mixing due to differences in speed, temperature, and sediment content. The Rio Negro is slower, warmer, and almost sediment-free, while the Solimões is faster, cooler, and carries Andean sediments. This striking visual contrast continues for many kilometres before blending fully.

    Is it true that China’s President Xi Jinping spent part of his childhood living in a cave?

    Answer: True

    As of 2010, approximately 3 million people in China’s Shanxi province resided in yaodong, which are caves dug into soft yet insulating dirt. These caves are naturally cool in summer and warm in winter, making them an affordable housing option. China’s president, Xi Jinping, spent part of his childhood in a similar cave in a nearby province. In 1968, at the age of 15, Xi applied to leave Beijing for the countryside, influenced by Mao Zedong’s Down to the Countryside Movement. On 13 January 1969, he moved to Liangjiahe Village in Yan’an, Shaanxi. The rural conditions were challenging which fostered his connection with the rural poor. Initially unable to adapt, he attempted to return to Beijing but was arrested and sent to a work camp. Persuaded by his aunt and uncle, he returned to the village, where he served as the party secretary and lived in a cave house.

    Answer: Hypertext Transfer Protocol

    HTTP, proposed by Tim Berners-Lee in 1989, is a foundational protocol for data exchange on the World Wide Web. It evolved from HTTP/1.0 (1996) to HTTP/1.1 (1997), introducing persistent connections and HTML decompression. HTTP/2 (2015) improved speed with binary data, while HTTP/3 (2022) uses QUIC for lower latency. HTTPS, adding encryption, is used by over 85% of websites. HTTP/3 supports 30.9% of websites as of February 2024.

    On 20 October 1973, which Australian landmark officially opened to the public?  
    Sydney Opera House
    The Sydney Opera House, which was opened by Queen Elizabeth II, was named a UNESCO World Heritage Site, whose citation is

    Inaugurated in 1973, the Sydney Opera House is a great architectural work of the 20th century that brings together multiple strands of creativity and innovation in both architectural form and structural design. A great urban sculpture set in a remarkable waterscape, at the tip of a peninsula projecting into Sydney Harbour, the building has had an enduring influence on architecture. The Sydney Opera House comprises three groups of interlocking vaulted ‘shells’ which roof two main performance halls and a restaurant. These shell-structures are set upon a vast platform and are surrounded by terrace areas that function as pedestrian concourses. In 1957, when the project of the Sydney Opera House was awarded by an international jury to Danish architect Jørn Utzon, it marked a radically new approach to construction.
