Input: Article: Critics of the Aeneid focus on a variety of issues. The tone of the poem as a whole is a particular matter of debate; some see the poem as ultimately pessimistic and politically subversive to the Augustan regime, while others view it as a celebration of the new imperial dynasty. Virgil makes use of the symbolism of the Augustan regime, and some scholars see strong associations between Augustus and Aeneas, the one as founder and the other as re-founder of Rome. A strong teleology, or drive towards a climax, has been detected in the poem. The Aeneid is full of prophecies about the future of Rome, the deeds of Augustus, his ancestors, and famous Romans, and the Carthaginian Wars; the shield of Aeneas even depicts Augustus' victory at Actium against Mark Antony and Cleopatra VII in 31 BC. A further focus of study is the character of Aeneas. As the protagonist of the poem, Aeneas seems to waver constantly between his emotions and commitment to his prophetic duty to found Rome; critics note the breakdown of Aeneas' emotional control in the last sections of the poem where the "pious" and "righteous" Aeneas mercilessly slaughters Turnus.

Now answer this question: When did Augustus' victory at Actium against Mark Antony and Ceopatra VII occur?

Output: 31 BC

Input: Article: Hydrogen production technologies been a significant area of solar chemical research since the 1970s. Aside from electrolysis driven by photovoltaic or photochemical cells, several thermochemical processes have also been explored. One such route uses concentrators to split water into oxygen and hydrogen at high temperatures (2,300–2,600 °C or 4,200–4,700 °F). Another approach uses the heat from solar concentrators to drive the steam reformation of natural gas thereby increasing the overall hydrogen yield compared to conventional reforming methods. Thermochemical cycles characterized by the decomposition and regeneration of reactants present another avenue for hydrogen production. The Solzinc process under development at the Weizmann Institute uses a 1 MW solar furnace to decompose zinc oxide (ZnO) at temperatures above 1,200 °C (2,200 °F). This initial reaction produces pure zinc, which can subsequently be reacted with water to produce hydrogen.

Now answer this question: What has been a main area of solar chemical research since the 1970s?

Output: Hydrogen production technologies

Input: Article: The remains of a 6th-century synagogue have been uncovered in Sepphoris, which was an important centre of Jewish culture between the 3rd–7th centuries and a multicultural town inhabited by Jews, Christians and pagans. The mosaic reflects an interesting fusion of Jewish and pagan beliefs. In the center of the floor the zodiac wheel was depicted. Helios sits in the middle, in his sun chariot, and each zodiac is matched with a Jewish month. Along the sides of the mosaic are strips depicting Biblical scenes, such as the binding of Isaac, as well as traditional rituals, including a burnt sacrifice and the offering of fruits and grains.

Now answer this question: The remains of what was found at Sepphoris?

Output:
a 6th-century synagogue
