Show answer & explanation
Correct answer: D
Concept
For consecutive-year data, the rate of increase is measured relative to the previous year's value.
Percentage increase = ((current value − previous value) / previous value) × 100. A negative result means a decrease.
Application
For 1998-99: ((2792 − 2593) / 2593) × 100 = (199 / 2593) × 100 ≈ 7.67%.
For 2000-01: ((2449 − 2535) / 2535) × 100 = (−86 / 2535) × 100 ≈ −3.39%, so the value decreased.
For 2003-04: ((1908 − 1802) / 1802) × 100 = (106 / 1802) × 100 ≈ 5.88%.
For 2005-06: ((2034 − 1727) / 1727) × 100 = (307 / 1727) × 100 ≈ 17.78%.
Cross-check
The absolute changes for the offered years are +199, −86, +106, and +307 thousand hectares respectively. The largest absolute increase and the largest percentage increase both occur in 2005-06. Therefore, the required year is 2005-06.
