Problem: Although nominally part of the Ottoman Empire, Yemen and the sahil came progressively under the control of Muhammad Ali, ruler of Egypt, between 1821 and 1841. After the Egyptians withdrew from the Yemeni seaboard in 1841, Haj Ali Shermerki, a successful and ambitious Somali merchant, purchased from them executive rights over Zeila. Shermerki's governorship had an instant effect on the city, as he manoeuvred to monopolize as much of the regional trade as possible, with his sights set as far as Harar and the Ogaden. Shermerki was later succeeded as Governor of Zeila by Abu Bakr Pasha, a local Afar statesman. In 1874-75, the Egyptians obtained a firman from the Ottomans by which they secured claims over the city. At the same time, the Egyptians received British recognition of their nominal jurisdiction as far east as Cape Guardafui. In actuality, however, Egypt had little authority over the interior and their period of rule on the coast was brief, lasting only a few years . The British Somaliland protectorate was subsequently established in the late 1880s, after the ruling Somali authorities signed a series of protection treaties granting the British access to their territories on the northwestern coast. Among the Somali signatories were the Gadabuursi , Habar Awal , and Warsangali. When the Egyptian garrison in Harar was eventually evacuated in 1885, Zeila became caught up in the competition between the Tadjoura-based French and the British for control of the strategic Gulf of Aden littoral. By the end of 1885, the two powers were on the brink of armed confrontation, but opted instead to turn negotiations. They later signed a convention on 1 February 1888 defining the border between French Somaliland and British Somaliland.

How many years after the Egyptians withdrew from the Yemeni seaboard did the Egyptians obtain a firman from the Ottomans which secured their claims over the city?
Answer: 33

Problem: The 100th Shipborne Fighter Aviation Regiment was formed at Saki in the Crimea on 10 March 1986. In January 1992 its personnel refused to take the oath of loyalty to Ukraine, which would have presumably made them part of the Ukrainian Navy or Ukrainian Air Force, and instead its personnel left for Russia, leaving their aircraft and equipment behind. The unit regrouped at Severomorsk-3 as part of the Northern Fleet. However, in February 1993 the regiment was disbanded and its personnel and equipment incorporated into the 279th Shipborne Fighter Aviation Regiment. The 279th Independent Shipborne Assault Aviation Regiment was established in 1973. In 1990 it became a Maritime Assault Aviation Regiment. On 22 February 1993 it was renamed the 279th Shipborne Fighter Aviation Regiment as it absorbed the remaining elements of the 100th Shipborne Fighter Aviation Regiment.

How many years did it take for the Maritime Assault Aviation Regiment to be renamed the 279th Shipborne Fighter Aviation Regiment?
Answer: 3
