- It is fed by the glaciers and joined by a number of tributaries which originates at different elevation in the hills
River Course of Brahmaputra River System
- The Brahmaputra River System (3848 km) is one of the longest rivers of the world. It is known as the Yarlung Tsangpo River in Tibet, the Brahmaputra, Lohit, Siang, and Dihang in India, and the Jamuna in Bangladesh.
- It traverses eastward longitudinally for a distance of nearly 1,200 km in a dry and flat region of southern Tibet, where it is known as the Tsangpo, which means ‘the purifier.’ The Rango Tsangpo is the major right bank tributary of this river in Tibet.
- It emerges as a turbulent and dynamic river after carving out a deep gorge in the Central Himalayas near Namcha Barwa (7,755 m).
- The river emerges from the foothills under the name of Siang or Dihang. It enters India west of Sadiya town in Arunachal Pradesh.
- Flowing southwest, it receives its main left bank tributaries, viz., Dibang or Sikang and Lohit; thereafter, it is known as the Brahmaputra.
- Among the tributaries Subansiri, Manas, Jiabharali, Pagladiya, Puthimari and Sankosh etc. are snow fed.

Kuril Islands dispute
- The Kuril Islands dispute, known as the Northern Territories dispute in Japan, is a territorial dispute between Japan and the Russian Federation over the ownership of the four southernmost Kuril Islands.
- The Kuril Islands are a chain of islands that stretch between the Japanese island of Hokkaido at their southern end and the Russian Kamchatka Peninsula at their northern end.
- The islands separate the Sea of Okhotsk from the Pacific Ocean.
- The four disputed islands, like other islands in the Kuril chain that are not in dispute, were annexed by the Soviet Union following the Kuril Islands landing operation at the end of World War II.
- The islands in dispute are:
- Iturup —Etorofu Island
- Kunashir —Kunashiri Island
- Shikotan —Shikotan Island
- Habomai Islands —Habomai Islands
San Francisco Treaty
- A substantial dispute regarding the status of the Kuril Islands arose between the U.S. and the Soviet Union during the preparation of the Treaty of San Francisco in 1951. The Treaty was supposed to be a permanent peace treaty between Japan and the Allied Powers of World War II.
- The Treaty of San Francisco was signed by 49 nations, including Japan and the United States, on September 8, 1951. Article (2c) states:
- "Japan renounces all right, title and claim to the Kurile Islands, and to that portion of Sakhalin and the islands adjacent to it over which Japan acquired sovereignty as a consequence of the Treaty of Portsmouth of 5 September 1905."
- The Soviet Union refused to sign the Treaty of San Francisco and publicly stated that the Kuril Islands issue was one of the reasons for its opposition to the Treaty.
- Japan signed and ratified the San Francisco treaty. However, both the Japanese government and most of the Japanese media currently claim that already at the time of the 1951 San Francisco peace conference, Japan held that the islands of Kunashiri, Etorofu, Shikotan and the Habomai Islands were technically not a part of the Kuril Islands and thus were not covered by the provisions of Article (2c) of the treaty.

Rare Earth Minerals
- The rare earths minerals (REM) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table in addition to scandium and yttrium that show similar physical and chemical properties to the lanthanides.
- Hence, Statement 1 is correct
- Rare earth minerals are not rare, they are commonly found in the earth’s crust. These metals are called rare because of the difficulties involved in extracting metals from the ore. The rare earth metals rarely occur in pure form. The costs involved in mining rare earth metals are very high.
- Hence, Statement 2 is incorrect
- The 17 Rare Earths are cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb), and yttrium (Y).
- One of the Rare Earths, Promethium, is radioactive
- Hence, Statement 3 is correct
- Because of their unique magnetic, luminescent, and electrochemical properties, these elements help make many technologies perform with reduced weight, reduced emissions, and energy consumption; or give them greater efficiency, performance, miniaturization, speed, durability, and thermal stability.
