TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: Who did Pasha want to defeat?, Context: Following the Ottoman ultimatum in September 1853, forces under the Ottoman general Omar Pasha crossed the Danube at Vidin and captured Calafat in October 1853. Simultaneously, in the east, the Ottomans crossed the Danube at Silistra and attacked the Russians at Oltenița. The resulting Battle of Oltenița was the first engagement following the declaration of war. The Russians counterattacked, but were beaten back. On 31 December 1853, the Ottoman forces at Calafat moved against the Russian force at Chetatea or Cetate, a small village nine miles north of Calafat, and engaged them on 6 January 1854. The battle began when the Russians made a move to recapture Calafat. Most of the heavy fighting, however, took place in and around Chetatea until the Russians were driven out of the village. Despite the setback at Chetatea, on 28 January 1854, Russian forces laid siege to Calafat. The siege would continue until May 1854 when the Russians lifted the siege. The Ottomans would also later beat the Russians in battle at Caracal.:130–43

SOLUTION: Russians

PROBLEM: How many things may mirror things with effects?, Context: The three marks of existence may reflect Upanishadic or other influences. K.R. Norman supposes that the these terms were already in use at the Buddha's time, and were familiair to his hearers.

SOLUTION: three

PROBLEM: Which one is group with ceratophyllum, Amborellales, monocots or eudicots?, Context: The exact relationship between these eight groups is not yet clear, although there is agreement that the first three groups to diverge from the ancestral angiosperm were Amborellales, Nymphaeales, and Austrobaileyales. The term basal angiosperms refers to these three groups. Among the rest, the relationship between the three broadest of these groups (magnoliids, monocots, and eudicots) remains unclear. Some analyses make the magnoliids the first to diverge, others the monocots. Ceratophyllum seems to group with the eudicots rather than with the monocots.

SOLUTION:
eudicots
