Match List I with List II: 

List I (Work)		List II (Scholar)
(A)	Crop- combination analysis	(I)	Stouffer
(B)	Isolated state	(II)	Whittlesey, D
(C)	Intervening  Opportunities	(III)	Von Thunen
(D)	Sequent occupance	(IV)	Weaver, J.C.

Choose the correct answer from the options given below:

Correct option is D

• (A) Crop-combination analysis → (IV) Weaver, J. C.
  • J.C. Weaver developed Crop Combination Analysis, which identifies patterns of crop cultivation in different regions based on statistical methods.
• (B) Isolated state → (III) Von Thunen
  • Von Thunen's model of the "Isolated State" (1826) explains the spatial arrangement of agricultural activities around a central market based on transportation cost and land use.
• (C) Intervening opportunities → (I) Stouffer
  • Samuel Stouffer introduced the concept of Intervening Opportunities (1940), which states that migration is influenced by opportunities found before reaching the final destination.
• (D) Sequent Occupance → (II) Whittlesey, D.
  • D. Whittlesey introduced Sequent Occupance, which explains how human landscapes change over time as different cultural groups occupy the same geographic area.

Thus, the correct answer is : A - IV, B - III, C - I, D - II.

Information Booster:

• Crop-combination analysis helps in determining which crops are grown together in a specific region.
• Von Thunen's Model explains land-use patterns in agricultural economics.
• Intervening opportunities impact migration and settlement patterns.
• Sequent Occupance describes historical changes in landscapes due to cultural and technological shifts.
