Q32. Which type of touchscreen functions by pressing two flexible layers together, allowing it to detect input from a non-conductive object like a fingernail or plastic stylus?

  1. (a) Capacitive touch
  2. (b) Surface acoustic wave
  3. (c) Resistive touch
  4. (d) Infrared grid touch
Answer & solution

Answer: (c) Resistive touch

Resistive Touchscreen:
• Has two thin flexible layers separated by a gap.
• When pressed, the layers touch each other and register the input.
• Works with any object — finger, fingernail, stylus (non-conductive).
• Used in ATMs, older smartphones, industrial equipment.
Capacitive Touchscreen:
• Uses electrical charge from the human body.
• Needs a conductive object (fingertip, not fingernail or regular stylus).
• Used in modern smartphones.
Surface Acoustic Wave: Uses ultrasonic waves; affected by dust/water.
Infrared Grid: Uses infrared beams; detects any object.
Answer: Option 3 → Resistive touch

Q33. Which statement is True or False regarding file management in Windows 11?
( i ) When a file is deleted and moved to the Recycle Bin, its contents are immediately and permanently erased from the storage disk.
(ii) The file path (C: > Users > Documents > file.txt) is a strictly hierarchical structure, meaning each file has one unique path.

  1. (a) ( i ) True, (ii) True
  2. (b) ( i ) True, (ii) False
  3. (c) ( i ) False, (ii) False
  4. (d) ( i ) False, (ii) True
Answer & solution

Answer: (d) ( i ) False, (ii) True

Statement ( i ): When a file is deleted and moved to the Recycle Bin, it is permanently erased.
→ FALSE.
Reason: Sending to Recycle Bin only marks the file for potential deletion.
It can be restored to its original location anytime.
Permanent deletion happens only when Recycle Bin is emptied
(or Shift+Delete is used).
Statement (ii): The file path (C: > Users > Documents > file.txt) is strictly hierarchical,
meaning each file has one unique path.
→ TRUE.
Reason: Windows NTFS uses a hierarchical tree structure.
Each file has exactly one absolute path in the directory tree.
Answer: Option 4 → ( i ) False, (ii) True

Human Eye and the Colourful World · Prism and dispersion of light

Q34. The formation of a spectrum by a glass prism occurs due to ________.

  1. (a) Dispersion
  2. (b) Scattering
  3. (c) Reflection
  4. (d) Refraction
Answer & solution

Answer: (a) Dispersion

When white light passes through a glass prism, it splits into a spectrum of seven colours (VIBGYOR).
This happens due to DISPERSION.
Why Dispersion?
• Different colours (wavelengths) of light travel at different speeds in glass.
• Each colour bends (refracts) by a different amount at the glass surface.
• Violet bends most, Red bends least (VBGYOR order of deviation).
Difference with other options:
• Scattering → why sky is blue (Rayleigh scattering of sunlight).
• Reflection → light bouncing back from a surface.
• Refraction → bending of light at one interface (not splitting into spectrum).
Answer: Option 1 → Dispersion

Basic Concepts and Economic Systems · Sectors of the economy (primary, secondary, tertiary)

Q35. In the context of India's pre-1991 economic structure, which of the following best characterizes the contradiction between sectoral GDP contribution and employment absorption?

  1. (a) Agriculture contributed declining GDP share but absorbed majority employment
  2. (b) Industry contributed the most to GDP and employment
  3. (c) Manufacturing became the primary employment generator
  4. (d) Services led GDP growth and employment generation equally
Answer & solution

Answer: (a) Agriculture contributed declining GDP share but absorbed majority employment

Key contradiction in pre-reform India:
• Agriculture's share of GDP was declining steadily.
• But agriculture still employed 60–70% of the total workforce.
Why?
• Structural transformation was incomplete — industries did not grow fast enough
to absorb the rural labour force.
• Low productivity in agriculture meant many remained farming for subsistence.
This is called the 'Structural Imbalance' or 'Dualistic Economy'.
Answer: Option 1 → Agriculture contributed declining GDP share but absorbed majority employment.
Money and Banking · NPAs and banking reforms (Narasimham, SARFAESI, IBC)

Q36. Which of the following reflects the structural adjustment in India’s monetary policy after the 1991 economic reforms?

  1. (a) Controlled lending rates for agriculture and MSMEs
  2. (b) Expansion of currency supply through deficit financing
  3. (c) Market-determined interest rates with reduced RBI intervention
  4. (d) Elimination of open market operations as a regulatory tool
Answer & solution

Answer: (c) Market-determined interest rates with reduced RBI intervention

Before 1991:
• Interest rates were administered (fixed) by RBI/Government.
• Directed lending to priority sectors at concessional rates.
• No market-determined rates.
After 1991 structural adjustment:
• Interest rates were gradually deregulated.
• Banks were allowed to fix their own lending and deposit rates.
• RBI shifted to indirect instruments (CRR, SLR, Repo Rate, OMO).
• MCLR (Marginal Cost of Funds based Lending Rate) introduced in 2016.
This reflects: Market-determined interest rates with reduced RBI intervention.
Answer: Option 3 → Market-determined interest rates with reduced RBI intervention.

Plant Physiology and Morphology · Mineral nutrition in plants

Q37. Which ions help chlorophyll to absorb light?

  1. (a) C
  2. (b) Na
  3. (c) Ca
  4. (d) Mg
Answer & solution

Answer: (d) Mg

Chlorophyll is the green pigment in plants responsible for absorbing light for photosynthesis.
Magnesium (Mg) is the central atom in the chlorophyll molecule.
• Mg²⁺ ion is at the core of the porphyrin ring structure.
• It enables the chlorophyll to capture light energy (especially in red & blue regions).
• Mg deficiency → yellowing of leaves (chlorosis).
Other ions and their roles:
• Ca → Cell wall formation, signal transduction.
• Na → Osmotic balance (in some plants).
• C → Backbone of all organic molecules.
Answer: Option 4 → Mg
Nutrition and Digestion · Nutrients - carbohydrates, proteins, fats

Q38. Which nutrient is primarily responsible for building and repairing tissues in the human body?

  1. (a) Carbohydrates
  2. (b) Fats
  3. (c) Proteins
  4. (d) Vitamins
Answer & solution

Answer: (c) Proteins

Proteins are the primary macronutrient responsible for building and repairing body tissues.
Functions of other nutrients:
• Carbohydrates → Main source of energy for the body.
• Fats → Long-term energy storage, insulation, absorption of fat-soluble vitamins.
• Vitamins → Regulatory functions, enzyme co-factors (do not build tissue directly).
• Proteins → Muscle building, tissue repair, enzymes, antibodies, hormones.
Key: Proteins are made of amino acids — the 'building blocks' of the body.
Answer: Option 3 → Proteins
