Problem: Religion in ancient Rome:

Lucan depicts Sextus Pompeius, the doomed son of Pompey the Great, as convinced "the gods of heaven knew too little" and awaiting the Battle of Pharsalus by consulting with the Thessalian witch Erichtho, who practices necromancy and inhabits deserted graves, feeding on rotting corpses. Erichtho, it is said, can arrest "the rotation of the heavens and the flow of rivers" and make "austere old men blaze with illicit passions". She and her clients are portrayed as undermining the natural order of gods, mankind and destiny. A female foreigner from Thessaly, notorious for witchcraft, Erichtho is the stereotypical witch of Latin literature, along with Horace's Canidia.

Problem: Incandescent light bulb:

In flood lamps used for photographic lighting, the tradeoff is made in the other direction. Compared to general-service bulbs, for the same power, these bulbs produce far more light, and (more importantly) light at a higher color temperature, at the expense of greatly reduced life (which may be as short as two hours for a type P1 lamp). The upper temperature limit for the filament is the melting point of the metal. Tungsten is the metal with the highest melting point, 3,695 K (6,191 °F). A 50-hour-life projection bulb, for instance, is designed to operate only 50 °C (122 °F) below that melting point. Such a lamp may achieve up to 22 lumens per watt, compared with 17.5 for a 750-hour general service lamp.

What lamp can achieve up to 23 lumens per watt?
---
A: unanswerable


Problem: Valencia:

During the second half of the 19th century the bourgeoisie encouraged the development of the city and its environs; land-owners were enriched by the introduction of the orange crop and the expansion of vineyards and other crops,. This economic boom corresponded with a revival of local traditions and of the Valencian language, which had been ruthlessly suppressed from the time of Philip V. Around 1870, the Valencian Renaissance, a movement committed to the revival of the Valencian language and traditions, began to gain ascendancy. In its early stages the movement inclined to the romanticism of the poet Teodor Llorente, and resisted the more assertive remonstrances of Constantine Llombart, founder of the still extant cultural society, Lo Rat Penat, which is dedicated to the promotion and dissemination of the Valencian language and culture.

What poet was an early influence on the Valencian Renaissance?
---
A:
Teodor Llorente
