[EX Q]: Question: What country is the island of Samothrace in now? Passage:The sculptor is unknown, although Paul MacKendrick suggests that Pythokritos of Lindos is responsible. When first discovered on the island of Samothrace (then part of the Ottoman Empire and called Semadirek) and published in 1863, it was suggested that the Victory was erected by the Macedonian general Demetrius Poliorcetes after his naval victory at Cyprus, between 295 and 289 BC. The Archaeological Museum of Samothrace continues to follow these originally established provenance and dates. Ceramic evidence discovered in recent excavations has revealed that the pedestal was set up about 200 BC, though some scholars still date it as early as 250 BC or as late as 180. Certainly, the parallels with figures and drapery from the Pergamon Altar (dated about 170 BC) seem strong. The evidence for a Rhodian commission of the statue has been questioned, however, and the closest artistic parallel to the Nike of Samothrace are figures depicted on Macedonian coins. Samothrace was an important sanctuary for the Hellenistic Macedonian kings. The most likely battle commemorated by this monument is, perhaps, the Battle of Cos in 255 BC, in which Antigonus II Gonatas of Macedonia won over the fleet of Ptolemy II of Egypt.

[EX Q]: Question: Who lived a longer life, Lucius Cornelius Sulla or Caecilius Metellus Pius? Passage:Lagos is an ancient maritime town with more than 2000 years of history. The name Lagos comes from a Celtic settlement, derived from the Latin Lacobriga, the name of the settlement was established during the pre-Punic civilizations. It became an early settlement of the Carthaginians, who recruited Celtic tribesmen in their war against the Romans (the Punic Wars). Owing to its already important harbour, it was colonized by the Romans and integrated into the Roman province of Lusitania, becoming known as Lacobriga. Quintus Sertorius, a rebellious Roman general, helped by the Lusitanians of Lacobriga (who had been oppressed under Roman Generals and members of Lucius Cornelius Sulla party), successfully defeated the Roman army of Caecilius Metellus Pius probably at nearby Monte Molião.
