Q1. Consider the following statements with reference to Hornbill:

1. The community-based conservation initiative in the Western Ghats involved the Kadar tribal community to restore the dwindling hornbill population.
2. The Great Hornbill is listed as a vulnerable species according to the International Union for Conservation of Nature (IUCN) Red List.

Which of the statements given above is/are correct?

a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2

Answer: (C)

Explanation:

  • A community-based conservation initiative involving the Kadar tribal community contributed to the restoration of the dwindling hornbill population in the Western Ghats. Thus, statement 1 is correct.
  • According to the International Union for Conservation of Nature (IUCN) Red List, the Great Hornbill is classified as vulnerable, while the Malabar Pied Hornbill is considered near-threatened. Thus, statement 2 is correct.

Q2. Consider the following statements:

1. Vietnam's success in electronics exports can be attributed to its strategic approach, including offering a corporate tax holiday and designating a specific province as the primary electronics manufacturing hub.
2. Geographical clusters have played a significant role in the historical development of industrial sectors worldwide.

Which of the statements given above is/are correct?

(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2

Answer: (C)

Explanation:

  • Vietnam's success in electronics exports can be attributed to its strategic approach, including offering a corporate tax holiday and designating a specific province as the primary electronics manufacturing hub. Thus, statement 1 is correct.
  • Statement 2 is correct because the historical development of industrial sectors, such as the loom industry in Manchester, the automotive industry in Detroit, and the emergence of Silicon Valley, has been influenced by the concentration of businesses in geographical clusters. This phenomenon demonstrates the network effects and economies of scale associated with clustered development.

Q3. Which ministry will be responsible for overseeing the implementation of the inter-operable criminal justice system (ICJS) as part of the government's plan to restore women's dignity?

a) Ministry of Women and Child Development.
b) Ministry of Home Affairs.
c) Ministry of Social Justice and Empowerment.
d) Ministry of Education

Answer: (B)

Explanation:

Inter-operable Criminal Justice System

  • To ensure effective monitoring of crimes against women, the government plans to implement an inter-operable criminal justice system (ICJS).
  • This system, developed as part of the Supreme Court's e-committee, will enable seamless transfer of data and information among courts, police, jails, and forensic laboratories.
  • The Ministry of Home Affairs will be responsible for overseeing the implementation of this aspect, ensuring efficient collaboration and sharing of vital information for swift investigation -and justice delivery. (Hence option b is correct).

Correct answer is (B) Ministry of Home Affairs.

Q4. Consider the following statements about X-Rays witnessed in space:

1. X-rays have much higher energy and much shorter wavelengths, between 0.03 and 3 nanometers.
2. The physical temperature of an object determines the wavelength of the radiation it emits.
3. The hotter the object, the larger the wavelength of peak emission.

How many of the statements given above are correct?

a) Only One
b) Only Two
c) All Three
d) None

Answer: (B)

Explanation:

How are X-Rays witnessed in space?

  • As NASA explains on its website, X-rays have much higher energy and much shorter wavelengths, between 0.03 and 3 nanometers, so small that some x-rays are no bigger than a single atom of many elements. (Hence statement 1 is correct).
  • The physical temperature of an object determines the wavelength of the radiation it emits. (Hence statement 2 is correct).
  • The hotter the object, the shorter the wavelength of peak emission. (Hence statement 3 is incorrect).

Additional Info.

  • X-rays come from objects that are millions of degrees Celsius — such as pulsars, galactic supernova remnants, and black holes.
  • “Like all forms of light, X-rays consist of moving electric and magnetic waves. Usually, peaks and valleys of these waves move in random directions. Polarised light is more organised with two types of waves vibrating in the same direction,” says a video from NASA on IXPE. It adds that fishermen use polarised lenses to reduce glare from sunlight when they are near water.

Therefore, the correct answer is option B: Only Two statements are correct.
