Q3:

Consider the following statements regarding the BrahMos Missile System:

It is a "fire-and-forget" ballistic missile that follows a high, arched trajectory.

It uses a two-stage propulsion system consisting of a solid rocket booster and a liquid-fuel ramjet engine.

It can be launched from multiple platforms including submarines, ships, aircraft, and land-based systems.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 2 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: C

Explanation:

Statement 1 is incorrect: BrahMos is not a ballistic missile, but rather a supersonic cruise missile. Cruise missiles fly at low altitudes, are powered throughout their entire trajectory, and remain highly maneuverable. In contrast, ballistic missiles follow a high, arched trajectory and are powered only in the initial phase.

Statement 2 is correct: BrahMos utilizes a two-stage propulsion mechanism. The first stage comprises a solid rocket booster that accelerates the missile to supersonic speeds. The second stage uses a liquid-fuel ramjet engine that compresses incoming air to sustain high-speed cruise flight without a rotating compressor.

Statement 3 is correct: BrahMos is a highly versatile, multi-platform weapon. It has been successfully developed and deployed for land-based systems (Indian Army), naval ships (Indian Navy), and fighter aircraft like the Su-30 MKI, as well as submarine-launched variants.

Q4:

With reference to India’s defence exports and the BrahMos missile, consider the following statements:

The Philippines was the first foreign buyer to sign an official deal with India for the BrahMos missile system.

The BrahMos missile is a joint venture between India's Defence Research and Development Organisation (DRDO) and Russia.

India holds a minority stake (less than 50%) in BrahMos Aerospace, the company producing the missile.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 2 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: A

Explanation:

Statement 1 is correct: In January 2022, the Philippines made history by signing a $375 million deal to become the first foreign buyer of the BrahMos anti-ship missile system. Following this success, India has continued expanding its defence export footprint by securing further agreements with nations like Vietnam.

Statement 2 is correct: BrahMos is a joint venture between India's DRDO and Russia's NPOM (NPO Mashinostroyenia).

Statement 3 is incorrect: India holds the majority stake in BrahMos Aerospace. India’s share in the collaboration stands at 50.5%, while Russia holds the remaining 49.5%.

Q5:

Consider the following statements regarding the Jayaprakash Narayan Bird Sanctuary (Surha Taal), recently designated as India's 100th Ramsar Site:

It is an artificial perennial reservoir built to support agriculture in the Gangetic plains.

It is connected to the Ganga River through a water channel known as the Kathar Nala.

It serves as a vital wintering habitat for migratory birds traversing the Central Asian Flyway.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 2 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: C

Explanation:

Statement 1 is incorrect: Surha Taal is a natural oxbow lake (a meander lake), not an artificial reservoir. Oxbow lakes are formed when a meandering river's bend is cut off, creating a U-shaped body of water.

Statement 2 is correct: It is a rain-fed lake that is connected to the holy Ganga River through a specific natural water channel called the Kathar Nala.

Statement 3 is correct: Surha Taal acts as an important wintering stopover and habitat for numerous bird species migrating along the Central Asian Flyway (CAF). It hosts thousands of international and indigenous birds during the winter months.
