Input: Consider Input: Question: How old was Pleistarchus's brother when he sent Pleistarchus to make headway against Ptolemy? Passage:Pleistarchus or Plistarch (; lived 4th century BC) was son of Antipater and brother of Cassander, king of Macedonia. He is first mentioned in the year 313 BC, when he was left by his brother in the command of Chalcis, to make headway against Ptolemy, the general of Antigonus, when Cassander himself was recalled to the defence of Macedonia. Again, in 302 BC, when the general coalition was formed against Antigonus, Pleistarchus was sent forward by his brother, with an army 12,000 foot and 500 horse, to join Lysimachus in Asia. As the Hellespont and entrance of the Euxine was occupied by Demetrius, he endeavoured to transport his troops from Odessus direct to Heraclea, but lost by far the greater part on the passage, some having been captured by the enemy's ships, while others perished in a storm, in which Pleistarchus himself narrowly escaped shipwreck. Notwithstanding this misfortune, he seems to have rendered efficient service to the confederates, for which he was rewarded after the battle of Ipsus (301 BC) by obtaining the province of Cilicia, as an independent government. This, however, he did not long retain, being expelled from it in the following year by Demetrius, almost without opposition. Afterwards he is recorded in inscriptions as the ruler of Caria; he was apparently given this province after the battle of Ipsus, and ruled there for at least seven years. Pausanias mentions him as having been defeated by the Athenians in an action in which he commanded the cavalry and auxiliaries of Cassander; but the period at which this event took place is uncertain. It is perhaps to him that the medical writer, Diocles of Carystus, addressed his work, which is cited more than once by Athenaeus, as τα προς Πλεισταρχον Υγιεινα.

Input: Consider Input: Question: How many other operas did the composers of Patience write? Passage:In September 2005, Ball made his New York City Opera debut as Reginald Bunthorne in Gilbert and Sullivan's Patience. He spent the first quarter of 2006 on complete vocal rest, following the illness that caused him to leave The Woman in White on Broadway. By the middle of July, Ball had taken part in the Royal Court Theatre's celebratory performance of The Rocky Horror Show. He took a leading role in Kismet in June and July 2007 for the ENO, and appeared on Channel 4's Richard & Judy on 22 June 2007 to promote this production. He then appeared as the solo artist in a controversial 'Musical Theatre' Prom on 27 August 2007 for the BBC at London's Royal Albert Hall. Ball performed a wide range of musical theatre numbers, including several by Andrew Lloyd Webber. The show was broadcast live on BBC Four, as well as on BBC Radio 3.

Input: Consider Input: Question: How long did the event in which  Sir Simon Fraser fought last? Passage:During the Scottish Wars of Independence, Sir Simon Fraser, known as "the Patriot", fought first with the Red Comyn, and later with Sir William Wallace and Robert the Bruce. Sir Simon is celebrated for having defeated the English at the Battle of Roslin in 1303, with just 8,000 men under his command. At the Battle of Methven in 1306, Sir Simon Fraser led troops along with Bruce, and saved the King's life in three separate instances. Simon was allegedly awarded the 3 Crowns which now appear in the Lovat Arms for these three acts of bravery. He was however captured by the English and executed with great cruelty by Edward I of England in 1306, in the same barbaric fashion as Wallace. At the Battle of Bannockburn in 1314, Sir Simon's cousin, Sir Alexander Fraser of Touchfraser and Cowie, was much more fortunate. He fought at Bannockburn, married Bruce's sister, and became Chamberlain of Scotland. The Frasers of Philorth who are chiefs of the senior Clan Fraser trace their lineage from this Alexander. Alexander's younger brother, another Sir Simon Fraser, was the ancestor of the chiefs of the Clan Fraser of Lovat. This Simon Fraser was killed at the Battle of Halidon Hill in 1333, along with his younger brothers Andrew and James.
