[EX Q]: The Ottoman Empire or, as a dynastic institution, the House of Osman was unprecedented and unequaled in the Islamic world for its size and duration. In Europe, only the House of Habsburg had a similarly unbroken line of sovereigns (kings/emperors) from the same family who ruled for so long, and during the same period, between the late 13th and early 20th centuries. The Ottoman dynasty was Turkish in origin. On eleven occasions, the sultan was deposed (replaced by another sultan of the Ottoman dynasty, who were either the former sultan's brother, son or nephew) because he was perceived by his enemies as a threat to the state. There were only two attempts in Ottoman history to unseat the ruling Ottoman dynasty, both failures, which suggests a political system that for an extended period was able to manage its revolutions without unnecessary instability. As such, the last Ottoman sultan Mehmed VI (r. 1918–1922) was a direct patrilineal (male-line) descendant of the first Ottoman sultan Osman I (r. 1299–1326), which was unparallelled in both Europe (e.g. the male line of the House of Habsburg became extinct in 1740) and in the Islamic world. The primary purpose of the Imperial Harem was to ensure the birth of male heirs to the Ottoman throne and secure the continuation of the direct patrilineal (male-line) descendance of the Ottoman sultans.
[EX A]: What was another name for the Ottoman Empire?

[EX Q]: In Hong Kong, the Supreme Court of Hong Kong (now known as the High Court of Hong Kong) was the final court of appeal during its colonial times which ended with transfer of sovereignty in 1997. The final adjudication power, as in any other British Colonies, rested with the Judicial Committee of the Privy Council (JCPC) in London, United Kingdom. Now the power of final adjudication is vested in the Court of Final Appeal created in 1997. Under the Basic Law, its constitution, the territory remains a common law jurisdiction. Consequently, judges from other common law jurisdictions (including England and Wales) can be recruited and continue to serve in the judiciary according to Article 92 of the Basic Law. On the other hand, the power of interpretation of the Basic Law itself is vested in the Standing Committee of the National People's Congress (NPCSC) in Beijing (without retroactive effect), and the courts are authorised to interpret the Basic Law when trying cases, in accordance with Article 158 of the Basic Law. This arrangement became controversial in light of the right of abode issue in 1999, raising concerns for judicial independence.

[EX Q]: Calculating that no further Russian advance was likely until 1758, Frederick moved the bulk of his eastern forces to Pomerania under the command of Marshal Lehwaldt where they were to repel the Swedish invasion. In short order, the Prussian army drove the Swedes back, occupied most of Swedish Pomerania, and blockaded its capital Stralsund. George II of Great Britain, on the advice of his British ministers, revoked the Convention of Klosterzeven, and Hanover reentered the war. Over the winter the new commander of the Hanoverian forces, Duke Ferdinand of Brunswick, regrouped his army and launched a series of offensives that drove the French back across the River Rhine. The British had suffered further defeats in North America, particularly at Fort William Henry. At home, however, stability had been established. Since 1756, successive governments led by Newcastle and Pitt had fallen. In August 1757, the two men agreed to a political partnership and formed a coalition government that gave new, firmer direction to the war effort. The new strategy emphasised both Newcastle's commitment to British involvement on the Continent, particularly in defence of Germany, and William Pitt's determination to use naval power to seize French colonies around the globe. This "dual strategy" would dominate British policy for the next five years.
