Explanation:

• The IOR-ARC, now known as the Indian Ocean Rim Association (IORA), was not established in response to recent incidents of piracy and oil spills. It was founded in March 1997 in Mauritius with the primary objective of promoting regional cooperation and sustainable development in the Indian Ocean region. Hence statement 1 is incorrect

• Although the IORA does address maritime security issues, it does not have a sole focus on maritime security. The organization's broader aim is to facilitate cooperation and collaboration among Indian Ocean-rim countries in various fields, including trade, economic development, environmental protection, academic and scientific exchange, and cultural engagement. Hence statement 2 is incorrect

Explanation:

• The research team put forward a hypothesis regarding the potential function of haemoglobin within chondrocytes. They suggested that haemoglobin in these cartilage cells might have a role in oxygen transport, similar to its well-known function in red blood cells, which is essential for delivering oxygen throughout the body. To investigate this hypothesis, the researchers conducted experiments.Hence statement 1 is incorrect

• During their investigations, they made a significant observation. When cartilage cells lacked haemoglobin, they exhibited signs of hypoxic stress. This condition is associated with low oxygen levels, indicating that the absence of haemoglobin leads to insufficient oxygen supply to these cells. This lack of oxygen had negative consequences for the chondrocytes.

• Conversely, in the presence of haemoglobin, the chondrocytes appeared to respond differently in low-oxygen environments. They seemed to release more oxygen under these conditions, which was crucial for their survival. This adaptation to low-oxygen environments was an intriguing finding, as it suggested that chondrocytes had developed an alternative mechanism for energy production that did not rely on oxygen in the same way that other cells do.Hence statement 2 is correct

Dialects: Lohara and Chaibasa-Thakurmunda. Script: Devanagari in Bihar, Oriya in Odisha.

Halbi Language

• Halbi, an Indo-Aryan language, is spoken in parts of Madhya Pradesh (Bastar district), Maharashtra, Odisha, and Andhra Pradesh. Dialects: Adkuri, Bastari, Chandari, Gachikolo, Mehari, Muri, Sundi.

Kui Language

• Kui, a South-Eastern Dravidian language, is spoken mainly by the Kandhas in Odisha. It is written in the Odia script.Hence statement 4 is correct

Explanation:

• The call for Bangla to be acknowledged as one of the national languages was voiced by the Constituent Assembly of Pakistan. In the aftermath of the 1947 partition of India, the Bengal region was split into two: East Bengal (subsequently becoming East Pakistan and then Bangladesh) and West Bengal (which became part of India). The populace of East Bengal, predominantly Bengali speakers, encountered discrimination as the Pakistani government favoured Urdu as the exclusive national language. This disparity prompted protests and appeals for the recognition of Bangla as a national language.Hence statement 1 is correct

• UNESCO, and not UNICEF, declares 21st February as International Mother Language Day.Hence statement 2 is incorrect
