[EX Q]: 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 .

[EX Q]: Question: Who won the Austrian Grand Prix in which Leclerc finished second? Passage:In China, Leclerc qualified 4th behind Vettel. After overtaking his teammate during the start, he was asked to yield and let Vettel pass. He eventually finished the Chinese Grand Prix in 5th. In Azerbaijan, he was the favourite for pole position until a crash in the second qualifying session ended his contention. He started 8th after penalties for the two Alfa Romeos and finished the race 5th with an extra point for the fastest lap of the race. At the following race in Monaco, he qualified 16th, as part of Ferrari's erroneous strategy that kept him in the garage to save tyres, underestimating track evolution at the end of the qualifying session. He was however promoted to 15th following Antonio Giovinazzi's grid penalty. He overtook Lando Norris and Romain Grosjean but suffered a puncture after a failed attempt to pass the Renault of Nico Hulkenberg. He also suffered severe floor damage to his car, leading to his second retirement at his home race. Leclerc qualified 3rd in Canada, ahead of Daniel Ricciardo in the Renault and behind Lewis Hamilton in the Mercedes. He would finish in the same position, his second podium finish of the season and of his career, behind the controversial 1-2 finish of Hamilton and teammate Sebastian Vettel. He would finish third again in France, having caught up to second-placed Bottas in the closing laps. At the Austrian Grand Prix, he qualified on pole position, the second pole of his Formula 1 career. He subsequently finished second after colliding with Red Bull's Max Verstappen, having led for the major part of the race. The incident was investigated by the stewards after the race, who called it 'a racing incident' and decided against taking action as neither of them was, wholly or predominantly, to blame for the incident.

Sumner and the Stamps Quartet in 1966. In 1972, he traveled briefly with the Blackwood Brothers, thereafter joining the Oak Ridge Boys as a member of The Mighty Oaks Band.
