Input: Consider Input: In 1869 the Suez Canal opened under Napoleon III, linking the Mediterranean with the Indian Ocean. Initially the Canal was opposed by the British; but once opened, its strategic value was quickly recognised and became the "jugular vein of the Empire". In 1875, the Conservative government of Benjamin Disraeli bought the indebted Egyptian ruler Isma'il Pasha's 44 percent shareholding in the Suez Canal for £4 million (£340 million in 2013). Although this did not grant outright control of the strategic waterway, it did give Britain leverage. Joint Anglo-French financial control over Egypt ended in outright British occupation in 1882. The French were still majority shareholders and attempted to weaken the British position, but a compromise was reached with the 1888 Convention of Constantinople, which made the Canal officially neutral territory.

Output: When did the Suez Canal open?


Input: Consider Input: Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and multicellular, which separates them from bacteria and most protists. They are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking rigid cell walls. All animals are motile, if only at certain life stages. In most animals, embryos pass through a blastula stage, which is a characteristic exclusive to animals.

Output: What sets animals apart from bacteria  and most protists?


Input: Consider Input: Russia, as a member of the Holy Alliance, had operated as the "police of Europe", maintaining the balance of power that had been established in the Treaty of Vienna in 1815. Russia had assisted Austria's efforts in suppressing the Hungarian Revolution of 1848, and expected gratitude; it wanted a free hand in settling its problems with the Ottoman Empire — the "sick man of Europe". The United Kingdom could not tolerate Russian dominance of Ottoman affairs, as that would challenge the British domination of the eastern Mediterranean.


Output: Who operated as the "police of Europe"?
