Input: Article: Slavery and slaves were part of the social order; there were slave markets where they could be bought and sold. Many slaves were freed by the masters for services rendered; some slaves could save money to buy their freedom. Generally, mutilation and murder of slaves was prohibited by legislation. However, Rome did not have a law enforcement arm. All actions were treated as "torts," which were brought by an accuser who was forced to prove the entire case himself. If the accused were a noble and the victim, not a noble, the likelihood of finding for the accused was small. At most, the accused might have to pay a fine for killing a slave. It is estimated that over 25% of the Roman population was enslaved.

Now answer this question: Were slave masters allowed to free their slaves in the Roman Republic?

Output: Many slaves were freed by the masters for services rendered

Input: Article: The first Europeans to disembark and explore the region were the Portuguese navigators Diogo Cao in 1485 and Bartolomeu Dias in 1486; still the region was not claimed by the Portuguese crown. However, like most of Sub-Saharan Africa, Namibia was not extensively explored by Europeans until the 19th century, when traders and settlers arrived, principally from Germany and Sweden. In the late 19th century Dorsland trekkers crossed the area on their way from the Transvaal to Angola. Some of them settled in Namibia instead of continuing their journey.

Now answer this question: When did Bartolomeu Dias explore Namibia?

Output: 1486

Input: Article: By this point Frederick was increasingly concerned by the Russian advance from the east and marched to counter it. Just east of the Oder in Brandenburg-Neumark, at the Battle of Zorndorf (now Sarbinowo, Poland), a Prussian army of 35,000 men under Frederick on Aug. 25, 1758, fought a Russian army of 43,000 commanded by Count William Fermor. Both sides suffered heavy casualties the Prussians 12,800, the Russians 18,000 but the Russians withdrew, and Frederick claimed victory. In the undecided Battle of Tornow on 25 September, a Swedish army repulsed six assaults by a Prussian army but did not push on Berlin following the Battle of Fehrbellin.

Now answer this question: How many Russians were in defense?

Output:
Russian army of 43,000
