PROBLEM: Which is not a name for the county: Hampshire, County Council, or Hantscire?, Context: After the establishment of Hampshire County Council, following the act in 1888, Southampton became a county borough within the county of Hampshire, which meant that it had many features of a county, but governance was now shared between the Corporation in Southampton and the new county council. There is a great source of confusion in the fact that the ancient shire county, along with its associated assizes, was known as the County of Southampton or Southamptonshire. This was officially changed to Hampshire in 1959 although the county had been commonly known as Hampshire or Hantscire for centuries. Southampton became a non-metropolitan district in 1974.

SOLUTION: County Council

PROBLEM: Which of the following was not defeated by Seleucus: Lysimachus, Demetrius, or Cassander?, Context: After Cassander's death in 298 BCE, however, Demetrius, who still maintained a sizable loyal army and fleet, invaded Macedon, seized the Macedonian throne (294) and conquered Thessaly and most of central Greece (293-291). He was defeated in 288 BC when Lysimachus of Thrace and Pyrrhus of Epirus invaded Macedon on two fronts, and quickly carved up the kingdom for themselves. Demetrius fled to central Greece with his mercenaries and began to build support there and in the northern Peloponnese. He once again laid siege to Athens after they turned on him, but then struck a treaty with the Athenians and Ptolemy, which allowed him to cross over to Asia minor and wage war on Lysimachus' holdings in Ionia, leaving his son Antigonus Gonatas in Greece. After initial successes, he was forced to surrender to Seleucus in 285 and later died in captivity. Lysimachus, who had seized Macedon and Thessaly for himself, was forced into war when Seleucus invaded his territories in Asia minor and was defeated and killed in 281 BCE at the Battle of Corupedium, near Sardis. Seleucus then attempted to conquer Lysimachus' European territories in Thrace and Macedon, but he was assassinated by Ptolemy Ceraunus ("the thunderbolt"), who had taken refuge at the Seleucid court and then had himself acclaimed as king of Macedon. Ptolemy was killed when Macedon was invaded by Gauls in 279, his head stuck on a spear and the country fell into anarchy. Antigonus II Gonatas invaded Thrace in the summer of 277 and defeated a large force of 18,000 Gauls. He was quickly hailed as king of Macedon and went on to rule for 35 years.

SOLUTION:
Cassander
