[Q]: Passage: In 1688 the most powerful navies were the French, English, and Dutch; the Spanish and Portuguese navies had suffered serious declines in the 17th century. The largest French ships of the period were the Soleil Royal and the Royal Louis. Each rated for 120 guns, they never carried their full complement. These ships were too large for practical purposes. The former only sailed on one campaign and was destroyed at La Hogue; the latter languished in port until sold in 1694. By the 1680s, French ship-design was at least equal to its English and Dutch counterparts, and by the Nine Years' War the French fleet had surpassed ships of the Royal Navy, whose designs stagnated in the 1690s. Innovation in the Royal Navy, however, did not cease. At some stage in the 1690s, for example, English ships began to employ the steering wheel, greatly improving their performance, particularly in heavy weather. 
Question: How many countries had the most powerful navies? 
Answer type: Number 
[A]: 3.


[Q]: 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. 
Question: How many years after the British occupied Sri Lanka was the Treaty of Amiens signed? 
Answer type: Number 
[A]:
6.
