Detailed Instructions: 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.
Q: Passage: More troops were brought in and on 2 January Khanzhalmikhe fell and 140 prisoners taken. This is the only mention of prisoners taken throughout the war. Gunib was relieved the next day. North up the canyon was Gerghebil which was considered the key to the relief of Kunzakh. On 7 or 8 January 2686 men began the attack. On 26 January the place fell to a night attack. Todorsky justified the heavy losses on the grounds that difficult victories demoralized the enemy. Two days later Khunzakh was relieved for a second time. The next move was north down the canyon to Arikani and Gimry. Arikani fell on 14 February. Gimry had been battered by artillery from late December, ninety percent of the village being destroyed. On 18 February it surrendered. With the core area occupied other places began to surrender. On the 19th Ashitla west of Gimry was occupied by 125 officer cadets. All were killed during the night and the next day 52 mutilated bodies were found. It is not clear what provoked this unusual brutality. The area to the northwest to the Chechen border was occupied: Botlikh , Andi and northward . On 9-13 March the Dagestan Reds linked up with those in Chechnya. On 15 March the Petrovsk Military Soviet declared the uprising liquidated. Meanwhile, on 25 February, Tiflis was occupied by the Red army. With Georgia now under Soviet control the remaining rebels in Dagestan were surrounded. The rebels made their last stand at Gidatl where the uprising was first organized. It fell in May. Small bands continued to resist until the end of May. The remaining insurgents dispersed to their villages. Said Bey fled to Turkey. The war took the lives of 5000 Reds and an unknown number of mountaineers.
A:
About how many months after the January attack did Arikani fall?
