Answer: C

Explanation:

Shortly after Meta revealed its Llama 3 Large Language Model (LLM), Microsoft introduced the newest iteration of its 'lightweight' AI model, dubbed the Phi-3-Mini. Phi-3-mini is the latest addition to Microsoft's lineup of AI models, designed to provide practical choices for generative AI applications. Hence, statement 1 is correct.

It boasts a parameter count of 3.8 billion and is accessible on various AI development platforms like Microsoft Azure AI Studio and HuggingFace. Available in two variants, one offering a 4K context-length and another with a context window of up to 128K tokens, enabling enhanced comprehension of large text content. Hence, statement 2 is correct.

It offers a context window of up to 128K tokens, making it the first model in its class to support such a feature without compromising quality. Instruction-tuned, facilitating responsiveness to diverse user instructions and immediate usability without additional tuning. Future plans include the introduction of Phi-3-small (7B) and Phi-3-Medium models to provide customers with more flexibility. Hence, statement 3 is correct.

Answer: C

Explanation:

The first true copy of Raja Ravi Varma's painting "Indulekha" will be unveiled on 29th April 2024, at Kilimanoor Palace, the birthplace of the legendary artist, commemorating his 176th birth anniversary celebrations. Indulekha is a painting by the renowned Indian artist Raja Ravi Varma, depicting the eponymous protagonist of the first modern novel in Malayalam literature, "Indulekha," authored by O. Chandu Menon and published in 1889. Hence, statement 1 is correct.

It was emerged in the public domain in 2022 and evoked a great sense of enthusiasm among the art fraternity. The novel is about the romantic love of a young Nair woman in 19th century Kerala and the societal constraints that affect it. The painting is believed to have been inspired by Olympia by Manet, but Varma replaced the boudoir with an upper-caste woman from Malabar, India to portray Indulekha's independent spirit. Hence, statement 2 is correct.

Raja Ravi Varma's painting style is known for its attention to detail, use of vibrant colors and depiction of Indian mythological and historical figures, reflecting the cultural ethos of the time. The painting's portrayal of Indulekha holding a letter addressed to her lover Madhavan encapsulates the romantic narrative of the novel and highlights themes of love and longing. Hence, statement 3 is correct.

Answer: B

Explanation:

Recently, the Geologists at MIT and Oxford University uncover ancient rocks in Greenland bearing remnants of Earth's earliest magnetic field, dating back approximately 3.7 billion years. The rocks retain signatures of a magnetic field with a strength of at least 15 microtesla, similar to Earth's present-day magnetic field, as revealed by a study published in the Journal of Geophysical Research. This discovery represents some of the earliest evidence of a magnetic field enveloping Earth, extending its known existence by another 200 million years, providing insights into the planet's early geological history. Scientists speculate that Earth's early magnetic field, by shielding the planet from damaging solar radiation while retaining a life-sustaining atmosphere, could have played a crucial role in fostering early life and making the planet habitable. Researchers aimed to find rocks preserving the Earth's magnetic field signatures when first formed, leading them to sample rock formations in Greenland's Isua Supracrustal Belt. Here, statements I and II both are correct but statement-II is not the correct explanation for statement-I. Hence, option (b) is correct.

Answer: C

Explanation:

Recently, white tigers sought relief from scorching temperatures by playing in a pond at Nehru Zoological Park, Hyderabad, as the India Meteorological Department issued a four-day heatwave warning for 12 districts in Telangana. Nehru Zoological Park, also known as Zoo Park, is a zoo in Hyderabad, Telangana. It is named after Jawaharlal Nehru, India's first Prime Minister. The zoo is considered one of the best in Asia and is home to over 1,500 species of birds, animals, and reptiles. Hence, statement 1 is correct.

The zoo was established on October 6, 1963 and is run by the forest department of the Government of Telangana. It was started in 1959 by relocating the erstwhile Zoo enclosures from Public Gardens, in Hyderabad. The Zoo is abutting the Mir-Alam Tank bund which is an indigenous arch bund dam with 24 arches formed 200 years ago. It was the first zoo in India to introduce initiatives like the Safari Park and Nocturnal Animal House. Hence, statement 2 is correct.

Answer: A

Explanation:

Combustion is a chemical reaction, specifically a redox reaction, where one substance (reductant) loses electrons and another substance (oxidant) gains electrons. It typically involves the burning of fuels such as fossil fuels (like petroleum) or biomass to produce energy. Combustion reactions release energy in the form of heat and light, which can be harnessed for various applications, including powering engines and generating electricity. Hence, statement 1 is correct.

Internal combustion engines power most cars and motorcycles, utilizing fossil fuels like petroleum for combustion, though electric vehicles are gradually re placing them. Combustion results in the formation of new chemical compounds, including carbon dioxide (CO₂), water vapor (H₂O) and other by-products depending on the specific fuel and conditions. Combustion of fossil fuels contributes to air pollution and greenhouse gas emissions, leading to environmental issues such as climate change and health concerns. Hence, statement 2 is incorrect.
