Task: Question Generation
Input (English): Passage: During the Napoleonic Wars, Great Britain, fearing that French control of the Netherlands might deliver Sri Lanka to the French, occupied the coastal areas of the island  with little difficulty in 1796. In 1802, the Treaty of Amiens formally ceded the Dutch part of the island to Britain and it became a crown colony. In 1803, the British invaded the Kingdom of Kandy in the first Kandyan War, but were repulsed. In 1815 Kandy was occupied in the second Kandyan War, finally ending Sri Lankan independence. Following the suppression of the Uva Rebellion the Kandyan peasantry were stripped of their lands by the Wastelands Ordinance, a modern enclosure movement, and reduced to penury. The British found that the uplands of Sri Lanka were very suitable for coffee, tea and rubber cultivation. By the mid-19th century, Ceylon tea had become a staple of the British market bringing great wealth to a small number of white tea planters. The planters imported large numbers of Tamil workers as indentured labourers from south India to work the estates, who soon made up 10% of the island's population. These workers had to work in slave-like conditions living in line rooms, not very different from cattle sheds.
Output (English): How many years were there between the start of the first Kandyan War and the start of the second Kandyan War?
