Correct Answer: a) Infra-red radiation

Explanation: Infra-red radiation is commonly used to provide relief from body aches and muscle pain. Infra-red rays have the ability to penetrate the skin and generate heat in the tissues, which helps improve blood circulation, relax muscles, and reduce pain or stiffness. This is why infra-red lamps or heating pads are often used in physical therapy and pain relief treatments. UV radiation and visible radiation do not have the same therapeutic effects for body aches, and hence they are not suitable for this purpose.

The correct answer is: c) EOJDJEFM

Explanation:

To decode how the word “COMPUTER” is transformed into “RFUVQNPC,” let’s analyze the pattern:

1. Reverse the Word:
– “COMPUTER” reversed is “RETUPMOC.”

2. Shift the Letters:
– First and Last Letters: The first letter ‘R’ and the last letter ‘C’ remain unchanged.
– Middle Letters: Each of the middle letters is shifted forward by +1 in the alphabet.
– E → F
– T → U
– U → V
– P → Q
– M → N
– O → P

– This transforms “RETUPMOC” to “RFUVQNPC.”

Applying the same pattern to the word “MEDICINE”:

1. Reverse the Word:
– “MEDICINE” reversed is “ENICIDEM.”

2. Shift the Letters:
– First and Last Letters: The first letter ‘E’ and the last letter ‘M’ remain unchanged.
– Middle Letters: Each of the middle letters is shifted forward by +1 in the alphabet.
– N → O
– I → J
– C → D
– I → J
– D → E
– E → F

– This transforms “ENICIDEM” to “EOJDJEFM.”

Correct Answer: c) EOJDJEFM

The correct answer is Option C: Swami Vivekanand in 1897.

Explanation: The Ramakrishna Mission was founded by Swami Vivekananda in 1897. It was established to propagate the teachings of his guru, Sri Ramakrishna Paramahamsa, and to work for the spiritual and social upliftment of society.

The correct answer is Option B: Anthrax.

Explanation: Anthrax is a bacterial disease caused by Bacillus anthracis. It is also referred to as “spleenic fever” because it often affects the spleen, causing it to become enlarged and inflamed. This disease primarily affects animals but can also infect humans through contact with infected animals or their products. The other options, Typhoid and Cholera, are bacterial diseases but are not associated with the term “spleenic fever.”

The correct answer is: Option C: Dilute sulphuric acid and sodium bicarbonate solution

Explanation:

A soda acid fire extinguisher works on the principle of producing carbon dioxide gas, which helps in extinguishing the fire by cutting off the supply of oxygen. The constituents of a soda acid fire extinguisher are dilute sulphuric acid and sodium bicarbonate solution. When these two substances react, they produce carbon dioxide gas along with water and sodium sulfate as by-products.

The reaction is as follows:
H2SO4 (dilute sulphuric acid) + 2NaHCO3 (sodium bicarbonate) → Na2SO4 (sodium sulfate) + 2H2O (water) + 2CO2 (carbon dioxide gas)

The carbon dioxide gas released is non-flammable and heavier than air, which helps in smothering the fire effectively. This is why the combination of dilute sulphuric acid and sodium bicarbonate solution is used in soda acid fire extinguishers.

The correct answer is: b) Patna

Explanation: The National Dolphin Research Centre (NDRC) has been recently inaugurated in Patna, the capital city of Bihar. This research center is dedicated to the conservation and study of the Gangetic dolphins, which are an endangered species and also the national aquatic animal of India. The location in Patna is significant as the Ganga River, which flows through the city, is a natural habitat for these dolphins. This initiative aims to promote awareness, research, and conservation efforts for the protection of these aquatic mammals.
