Neco Model Questions Vol1 2020 Geography Question 13

Region A and Region B are being evaluated for the cultivation of Crop X, which requires an annual rainfall between 900 mm and 1100 mm and prefers low population density (< 50 persons/km²). The data are:\n\n- Region A: population density = 45 persons/km², GDP per capita = $1,500, annual rainfall = 950 mm\n- Region B: population density = 70 persons/km², GDP per capita = $2,000, annual rainfall = 1,050 mm\n\nA suitability index (SI) is calculated as follows:\n\n\(SI = 0.5\times R_f + 0.3\times P_f + 0.2\times G_f\)\n\nwhere \(R_f = 1\) if rainfall is within the required range, otherwise 0; \(P_f = 1\) if density < 50, otherwise 0; and \(G_f = \frac{\text{maxGDP} - \text{GDP}}{\text{maxGDP} - \text{minGDP}}\). Determine which region has the higher suitability index for Crop X.
