Q1.Consider the following statements about African continent

1. Africa is the second largest continent after Asia

2. It is the only continent through which the Tropic of Cancer, the Equator and the Tropic of Capricorn pass

3. The Sahara Desert, the world’s largest hot desert, is located in Africa

Which of the above statements is/are correct?

a. 1 and 2 only

b. 2 and 3 only

c. 3 only

d. 1, 2 and 3

Answer (d)

Explanation:

Africa is the second largest continent after Asia. The Equator or 00

latitude runs almost through the middle of the continent. A large part of Africa lies in the Northern Hemisphere. It is the only continent through which the Tropic of Cancer, the Equator and the Tropic of Capricorn pass. The Sahara Desert, the world’s largest hot desert, is located in Africa. The continent is bound on all sides by oceans and seas. The world’s longest river, the Nile, flows through Africa.

Q2. The Light Combat Helicopter (LCH) is the only attack helicopter in the world that can land and take off at an altitude of 5,000 metres (16,400 ft). The helicopter being discussed is

a. Chinook

b. Apache

c. Tejas

d. Prachand

Answer (d)

Explanation:

• The Light Combat Helicopter (LCH) is the only attack helicopter in

the world that can land and take off at an altitude of 5,000 metres (16,400 ft).

• The helicopter can fly at a maximum speed of 288 kmph and has a combat radius of 500 km, which can go up to a service ceiling of 21,000 feet, making it ideal to operate in Siachen. It incorporates several stealth features such as reduced radar and infrared signatures.

• It can be deployed to perform Combat Search and Rescue (CSAR), bunker busting operations, counter-insurgency operations in the jungle and urban areas and support the ground forces.

Q3.Consider the following statements about NASA’s Sonification Project

1. NASA is translating the images and data obtained using James Web Space Telescope into Sound

2. Sonification is the use of non-speech audio to convey information or perceptualize data

Which of the above statements is/are correct?

a. 1 only

b. 2 only

c. Both 1 and 2

d. Neither 1 nor 2

Answer (c)

Explanation:

NASA is translating the images and data obtained using James Web

Space Telescope into Sound. Sonification is the use of non-speech audio to convey information or perceptualize data. Nasa did so for Cosmic Cliffs in the Carina Nebula.

Benefits: NASA believes that visually-impaired people will benefit the most from this sonification project.

How were the sounds captured? Similar to how written descriptions are unique translations of visual images, sonification also translates the visual images by encoding information, like colour, brightness, star locations, or water absorption signatures, as sounds.

Q4. Consider the following statements

1. It is mandatory for mobile phone manufacturers to register the International Mobile Equipment Identity (IMEI) of all handsets made in India with the government

2. IMEI is 25 digit number

Which of the above is/are correct?

a. 1 only

b. 2 only

c. Both 1 and 2

d. Neither 1 nor 2

Answer (a)

Explanation:

The Department of Telecommunications (DoT) has made it

mandatory for mobile phone manufacturers to register the International Mobile Equipment Identity (IMEI) – the 15-digit number that uniquely identifies each mobile device – of all handsets made in India with the government.

What is the IMEI number, and its function?

• The IMEI is a unique number that is used to identify a device on a mobile network. It has 15 digits and is like a phone’s unique identity. The number is used to verify the identity of a device when a user uses the Internet or places a call through it.

• Phones with a dual-SIM option have two IMEI numbers, one for each SIM. The IMEI number can help network providers track down a device in case it gets stolen or lost. Once such loss or theft is reported, the carriers can deny the device access to the cellular network even with a new SIM card.

Q5. Which of the following are uses of Extended reality (XR)?

1. Training for soldiers, driving, surgeons

2. Testing for corporates

3. Tourism

Select the correct answer using the code given below

a. 1 and 2 only

b. 2 and 3 only

c. 1 and 3 only

d. 1, 2 and 3

Answer (d)

Explanation:

MeitY has collaborated with Meta (facebook's parent company) to

accelerate XR technology start-ups in India. Extended reality (XR) is an umbrella term referring to all real-and-virtual combined environments and human-machine interactions generated by computer technology and wearables.

Applications:

• Training: e.g., for soldiers, driving, surgeons

• Testing: for corporates

• Tourism: virtual tours

Issues:

• No concrete data privacy law is in place yet.

• The cost of equipment is high for common men to afford

• Lack of digital literacy
