Please answer this: Extract the answer to the question from the following context. Question: What did Demetrius do before invading Thessaly? 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.

Problem: Given the question: Extract the answer to the question from the following context. Question: What city became a secondary capital of the Western Roman Empire? Context: In the following century Ravenna, the capital of the Western Roman Empire, became the center of late Roman mosaic art (see details in Ravenna section). Milan also served as the capital of the western empire in the 4th century. In the St Aquilinus Chapel of the Basilica of San Lorenzo, mosaics executed in the late 4th and early 5th centuries depict Christ with the Apostles and the Abduction of Elijah; these mosaics are outstanding for their bright colors, naturalism and adherence to the classical canons of order and proportion. The surviving apse mosaic of the Basilica of Sant'Ambrogio, which shows Christ enthroned between Saint Gervasius and Saint Protasius and angels before a golden background date back to the 5th and to the 8th century, although it was restored many times later. The baptistery of the basilica, which was demolished in the 15th century, had a vault covered with gold-leaf tesserae, large quantities of which were found when the site was excavated. In the small shrine of San Vittore in ciel d'oro, now a chapel of Sant'Ambrogio, every surface is covered with mosaics from the second half of the 5th century. Saint Victor is depicted in the center of the golden dome, while figures of saints are shown on the walls before a blue background. The low spandrels give space for the symbols of the four Evangelists.

input question: Extract the answer to the question from the following context. Question: What general term can be used to describe mestizos and others? Context: These patterns of discrimination against non-whites have led some academic and other activists to advocate for use of the Portuguese term negro to encompass all African-descended people, in order to stimulate a "black" consciousness and identity. This proposal has been criticized since the term pardo is considered to include a wide range of multiracial people, such as caboclos (mestizos), assimilated Amerindians and tri-racials, not only people of partial African and European descent. Trying to identify this entire group as "black" would be a false imposition of a different identity from outside the culture and deny people their other, equally valid, ancestries and cultures. It seems a one-drop rule in reverse.???
output answer: pardo

Context: The NFL Network ceased airing Arena Football League games partway through the 2012 season as a result of ongoing labor problems within the league. Briefly, the games were broadcast on a tape delay to prevent the embarrassment that would result should the players stage a work stoppage immediately prior to a scheduled broadcast. (In at least once incidence this actually happened, resulting in a non-competitive game being played with replacement players, and further such incidents were threatened.) Once the labor issues were resolved, the NFL Network resumed the practice of broadcasting a live Friday night game. NFL Network dropped the league at the end of the 2012 season.
