Theories of Human Development

• Cross-Dyeing and Solid-Shade Dyeing of Fiber Blends:
• Assertion (A): It is possible to dye textiles containing fibres having different dye affinity, with one solid colour using a single dye bath. $\implies$ Correct.
• In blend dyeing (e.g., polyester/cotton or wool/acrylic blends), union dyeing produces a uniform solid shade throughout the fabric from a single dye bath containing compatible dye classes.
• Reason (R): Dyes having affinity for different fibre types can be used to produce one solid colour. $\implies$ Correct.
• By formulating a combination of disperse dyes (for polyester) and reactive dyes (for cellulose) tailored to each fiber component's specific chemical affinity, both components absorb their respective chromophores at equal visual depths, yielding a solid uniform color.
• Conclusion: Both (A) and (R) are correct and (R) is the correct explanation of (A) (Option 1).

Correct option: (1) Both (A) and (R) are correct and (R) is the correct explanation of (A).

• National Education Policy (NEP 2020) Curricular Structure:
• The 5+3+3+4 Pedagogical Framework:
• NEP 2020 replaced the colonial $10+2$ school structure with a child-centered $5+3+3+4$ design covering ages 3 to 18:

• Foundational Stage (5 years, ages 3–8): 3 years of Anganwadi/Pre-school + Classes 1 and 2 (play-based pedagogy).
• Preparatory Stage (3 years, ages 8–11): Classes 3 to 5 (experiential, activity-based learning).
• Middle Stage (3 years, ages 11–14): Classes 6 to 8 (subject-oriented critical thinking, vocational skills).
• Secondary Stage (4 years, ages 14–18): Classes 9 to 12 (multidisciplinary study, semester flexibility).
  • Conclusion: 5+3+3+4 (Option 1).
