31. Which of the following diseases can be caused due to excessive use of digital technology?
- Digital Amnesia
- Synaptic Pruning
- Tendonitis
- Cyberchondria
Choose the correct answer using the codes given below:
[A] Only 1
[B] Only 1, 2 & 4
[C] Only 1 & 4
[D] 1, 2, 3 & 4
Show Answer
Correct Answer: D [1, 2, 3 & 4]
Notes:
Digital amnesia refers to the decline in memory retention due to reliance on technology. Synaptic pruning, necessary for forming new memories, is hindered by interrupted sleep. Tendonitis arises from poor arm and wrist positioning during prolonged use of devices, sometimes termed “textinitis” or “Nintendonitis.” Cyberchondria is the compulsive online search for health information, often driven by unfounded fears of rare diseases.

Notes:
ICMR has approved nine molecular tests for COVID-19 diagnosis: Open system RTPCR, TrueNat (originally for TB, modified for COVID-19), GeneXpert (cartridge-based, initially for TB), RTLAMP (one-step nucleic acid amplification for RNA viruses), and others including CRISPR/TATAMD CHECK/FELUDA, Abbott ID Now, Accula by Thermofisher, Rapid RTPCR, and CoviDx DirectPlex. SPERA COVID-19 test is FDA-approved but not by ICMR.
33. Which of the following statements is/are correct about the new combat uniform?
- The cotton-to-polyester ratio is 70:30.
- The fabric is 15 per cent lighter, and has 23 per cent more strength against tearing.
- The pattern is digital.
Choose the correct answer using the codes given below:
[A] Only 1 & 2
[B] Only 2 & 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: D [1, 2 & 3]
Notes:
The new uniform features a digital camouflage pattern in olive green and earth tones, replacing the old design from 2008. It is made from a lighter, sturdier, and more breathable fabric with a 70:30 cotton-to-polyester ratio, making it quicker to dry and comfortable in humid conditions. The new material is 15% lighter and 23% stronger against tearing. Ergonomic and micro features enhance comfort for long use. The uniform includes a combat T-shirt and an untucked shirt. A modified version has been created for female officers and troops.
34. Which of the following is / are correct statements about NISAR mission of ISRO?
- It is a joint earth observation mission of NASA and ISRO
- It is first radar imaging satellite that uses dual frequencies
Select the correct answer from the codes given below:
[A] Only 1 is correct
[B] Only 2 is correct
[C] Both 1 & 2 are correct
[D] Neither 1 nor 2 is correct
Show Answer
Correct Answer: C [Both 1 & 2 are correct ]
Notes:
The NISAR Mission is a joint NASA-ISRO earth observation initiative using Synthetic Aperture Radar (SAR) to capture high-resolution images. It will scan the Earth’s land and ice every 12 days over a three-year period and is the first radar imaging satellite to utilize dual frequencies. The mission aims to measure processes such as ice sheet collapse, ecosystem disturbances, and natural hazards like volcanic eruptions, tsunamis, and earthquakes.
35. Which of the following statements regarding categories of chips is/are correct:
- Commodity integrated circuits are used in barcode scanners.
- Analog chips are less prone to noise, or small variations in voltage.
- Read-only memory and programmable read-only memory chips can be modified.
Select the correct answer using the codes given below:
[A] Only 1
[B] Only 1 & 2
[C] Only 2 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: A [Only 1]
Notes:
Commodity integrated circuits are used in devices like barcode scanners for repetitive tasks. Analog chips are actually more prone to noise due to their reliance on continuous signals. Read-only memory (ROM) and programmable ROM (PROM) cannot be modified after manufacture; only EPROM and EEPROM are designed to be erasable and reprogrammable.
36. Which among the following is/are input devices?
- Keyboard
- Scanner
- Joy-stick
Select the correct answer from the codes given below:
[A] Only 1 and 2
[B] Only 2 and 3
[C] Only 1 and 3
[D] All of the above
Show Answer
Correct Answer: D [All of the above ]
Notes:
Keyboard, scanner and joystick are all examples of input devices since they provide data and control signals to an information processing system such as a computer or information appliance. Input devices represent one type of computer peripheral – the other two types are output devices and storage devices.
37. Consider the following statements:
- The i-ATS system is India’s first indigenously developed Train Control and Supervision System.
- India is the fourth country to develop its own ATS products after France, Japan, and China.
Which of the above statements is/are correct?
[A] Only 2
[B] Both 1 and 2
[C] Only 1
[D] Neither 1 nor 2
Show Answer
Correct Answer: C [Only 1]
Notes:
Statement 1 is correct as i-ATS is India’s first indigenously developed Train Control and Supervision System. Statement 2 is incorrect because India became the sixth country, not the fourth, to have its own ATS products, after France, Germany, Japan, Canada, and China. Thus, only statement 1 is correct.
38. With respect to the new regulations on Doctor of Philosophy degrees, consider the following statements:
- Anyone with a minimum of 55 per cent marks in Bachelors’ programme is eligible for a PhD.
