Question 21: Consider the following statements:

  1. Lasers travel at light-speed and have long range.
  2. A directed-energy weapon is a ranged weapon that damages its target with highly focused energy without a solid projectile.
  3. Light is, for practical purposes, unaffected by gravity, windage and Coriolis force.
  4. The first use of directed-energy weapons in combat between military forces was in the second world war.

Which of the following statements is/are true?

  1. 1, 2 and 3
  2. 2, 3 and 4
  3. 1, 3 and 4
  4. 1, 2, 3 and 4

Correct Answer: A

Explanation

Directed energy weapons could have several main advantages over conventional weaponry:

  • Directed-energy weapons can be used discreetly; radiation does not generate sound and is invisible if outside the visible spectrum.
  • Light is, for practical purposes, unaffected by gravity, windage and Coriolis force, giving it an almost perfectly flat trajectory. This makes aim much more precise and extends the range to line-of-sight, limited only by beam diffraction and spread (which dilute the power and weaken the effect), and absorption or scattering by intervening atmospheric contents.
  • Lasers travel at light-speed and have long range, making them suitable for use in space warfare.
  • Laser weapons potentially eliminate many logistical problems in terms of ammunition supply, as long as there is enough energy to power them.
  • A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams.
  • The first use of directed-energy weapons in combat between military forces was claimed to have occurred in Libya in August 2019 by Turkey, which claimed to use the ALKA directed-energy weapon.

  • In reserved forests, local people are prohibited, unless specifically allowed by a Forest Officer in the course of the settlement.

Question 24: Retail inflation for September was 7.4 per cent in 2022, which means:

  1. The price level for retail consumers last month was 7.4 per cent higher than what it was in September 2021.
  2. The retail inflation has been outside the RBI’s comfort zone for three consecutive quarters beginning January.

Which of the following statements is/are true?

  1. 1 only
  2. 2 only
  3. 1 and 2 only
  4. Neither 1 nor 2

Correct Answer: C

Explanation

  • Retail inflation for September was 7.4 per cent — which means the price level for retail consumers last month was 7.4 per cent higher than what it was in September This also means that retail inflation — which is calculated using the Consumer Price Index (CPI) — has been outside the RBI’s comfort zone for three consecutive quarters beginning January.
