Example Input: Passage: In 1860, there were 20,000 professionals in Russia and 85,000 by 1900. Originally composed of educated nobles, the intelligentsia became dominated by raznochintsy (class-less people) after 1861. In 1833, 78.9 per cent of secondary-school students were children of nobles and bureaucrats, by 1885 they were 49.1 per cent of such students. The proportion of commoners increased from 19.0 to 43.8 per cent, and the remaining percentage were the children of priests. In fear of an educated proletariat, Tsar Nicholas I of Russia limited the number of university students to 3,000 per year, yet there were 25,000 students, by 1894. Similarly the number of periodicals increased from 15 in 1855 to 140 periodical publications in 1885. The "third element" were professionals hired by zemstva. By 1900, there were 47,000 of them, most were liberal radicals.

Example Input: 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 
Example Output: 3.
