This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Passage: For background see Russian conquest of the Caucasus. Around 1560 Russia interacted with Kabardia but thereafter left the region alone except for the Caspian coast. In 1800 Russia annexed eastern Georgia and by 1806 held Transcaucasia from the Black Sea to the Caspian. Since Russia also claimed the steppes north of the mountains its claims were divided by the free mountaineers of the Caucasus. Russia had to hold the Georgian Military Highway in the center so the war against the mountaineers was divided into eastern and western parts. Circassia refers to a region the majority of whose inhabitants before the 1860s were the Adygey ethnic group, known to the West as Circassians. This region consisted for the most part of the region between the westward flowing Kuban River to the north and the Caucasus mountain range to the south, although the Kuban River constituted only part of the northern boundary. The Circassians were never politically united for a long period. The western bulk of Circassia, they belonged to any of about ten tribes, living in communities headed by chieftains. In the east of Circassia were two feudal polities, Greater Kabarda and Lesser Kabarda. In the late 1550s, the ruler of one of the Kabardas, Temryuk , struck a politico-military alliance with Tsar Ivan IV of Russia , for mutual assistance against expansionist attacks by the Persian and Ottoman Empires. In this period of history, the Circassians were Christians; Islam did not begin to penetrate Circassia until the following century. In the 1560s Ivan and Temryuk directed forts to be constructed, including Tumnev at the western end of Circassian lands and at Sunzha Ostrog at the mouth of the Sunzha river, at the eastern end of Circassian lands.
After annexing Georgia, how many years did it take Russia to control Transaucasia?
