Which one of the following rivers is not a tributary of river Brahmaputra ?
- A.River Manas
- B.River Kameng
- C.River Mahananda
- D.River Subansiri
Correct answer
Explanation
The correct answer is C, River Mahananda. The Mahananda rises in the Darjeeling hills, flows through north Bengal and Bihar and joins the Ganga, not the Brahmaputra.
The Brahmaputra, called the Tsangpo in Tibet and the Siang or Dihang in Arunachal Pradesh, enters Assam and receives many Himalayan tributaries on its right bank. The Subansiri, its largest tributary, comes from Tibet through Arunachal Pradesh. The Kameng, also called the Jia Bhareli, drains western Arunachal Pradesh. The Manas flows out of Bhutan and gives its name to the Manas National Park on the Assam–Bhutan border. The Mahananda, by contrast, drains into the Ganga system near the Bihar–Bengal border.
A is wrong because the Manas, flowing from Bhutan, is a right-bank tributary of the Brahmaputra. B is wrong because the Kameng from Arunachal Pradesh joins the Brahmaputra near Tezpur. D is wrong because the Subansiri is the largest tributary of the Brahmaputra.
Exam tip: right-bank tributaries of the Brahmaputra include Subansiri, Kameng, Manas, Sankosh and Teesta; the Mahananda belongs to the Ganga.

Zone between 105° and 145° from epicentre was identified as the shadow zone for both P-waves and S-waves 2. The shadow zone of P-waves is much larger than that of the S-waves Select the answer using the code given below:
- A.1 only
- B.2 only
- C.Both 1 and 2
- D.Neither 1 nor 2
Show answer
The band between 105° and 145° from the epicentre receives neither P-waves nor S-waves, but it is the S-wave shadow zone that is much larger, so statement 2 is wrong.

- B.2 and 3 only
- C.1 only
- D.1, 2 and 3
Show answer
The Ring of Fire around the Pacific is a belt of convergent plate boundaries, full of active volcanoes and earthquakes and lined by deep ocean trenches.

These storms develop during the summer and autumn in every tropical ocean except the South Atlantic and eastern South Pacific Oceans. 2. Tropical cyclones that occur in the North Atlantic and eastern North Pacific Oceans are known as typhoons. 3. Tropical cyclones that occur in the Indian and South Pacific Oceans are called cyclones. Select the answer using the code given below :
- A.3 only
- B.1 and 2 only
- C.1 and 3 only
- D.1, 2 and 3
Show answer
Tropical cyclones of the North Atlantic and eastern North Pacific are called hurricanes, not typhoons, so statement 2 is wrong.
Read the full explanation →Which of the following statements is/are correct ? 1. Oceanic trenches are very significant in the study of plate movements 2. Oceanic trenches are associated with active volcanoes and strong earthquakes Select the answer using the code given below:
- A.1 only
- B.2 only
- C.Both 1 and 2
- D.Neither 1 nor 2
Show answer
Oceanic trenches mark the places where one plate sinks beneath another, so they are key evidence for plate movement and are lined by volcanoes and earthquakes.
