S1: The National Forest Policy (1952) has outlined that the desired forest area of a country must be at least 33 per cent of the geographical area.
S6: Some land is termed as land put to other non-agricultural uses; this includes settlements, roads, railways, industries, etc.
P: However the present forest cover is only 23 per cent, much lower than the desired percentage.
Q: This was felt to be necessary for maintaining the ecological balance.
R: Some land is termed as wasteland; this includes rocky, arid and desert areas.
S: This creates difficulties for millions of people who live in the fringe areas of forests and depend upon the forests for their livelihood.

The correct answer is 'Option 4'.

Key Points

• S1: The National Forest Policy (1952) has outlined that the desired forest area of a country must be at least 33 per cent of the geographical area.
  • This sentence introduces the policy and the desired forest cover percentage.
• Q: This was felt to be necessary for maintaining the ecological balance.
  • The pronoun "This" refers to the 33 percent desired forest area mentioned in S1, and Q explains the reason for this policy target. This creates a strong cause-and-effect link.
• P: However the present forest cover is only 23 per cent, much lower than the desired percentage.
  • The word "However" indicates a contrast with the ideal scenario (33%) presented in S1 and Q, introducing the current, lower reality (23%). This logically follows the discussion of the ideal.
• S: This creates difficulties for millions of people who live in the fringe areas of forests and depend upon the forests for their livelihood.
  • The demonstrative "This" in S refers to the low forest cover (23%) mentioned in P, detailing a direct socio-economic consequence of this disparity. This forms a strong problem-consequence link.
• R: Some land is termed as wasteland; this includes rocky, arid and desert areas.
  • Following the discussion on forest cover and its human impact, the paragraph transitions to categorizing other types of land. R introduces "wasteland" as one such category, providing examples.
• S6: Some land is termed as land put to other non-agricultural uses; this includes settlements, roads, railways, industries, etc.
  • This concluding sentence introduces another category of land use ("non-agricultural uses"), parallel to "wasteland" in R, continuing the broader discussion of land utilization.
• The sequence Q-P-S-R provides a coherent flow: stating the policy goal (S1), explaining its rationale (Q), presenting the current shortfall (P), detailing the human impact of the shortfall (S), and then diversifying into other land classifications (R, followed by S6).
