Problem: Please answer a question about the following article about Edmund Burke:
Burke was born in Dublin, Ireland. His mother Mary née Nagle (c. 1702 – 1770) was a Roman Catholic who hailed from a déclassé County Cork family (and a cousin of Nano Nagle), whereas his father, a successful solicitor, Richard (died 1761), was a member of the Church of Ireland; it remains unclear whether this is the same Richard Burke who converted from Catholicism. The Burke dynasty descends from an Anglo-Norman knight surnamed de Burgh (latinised as de Burgo) who arrived in Ireland in 1185 following Henry II of England's 1171 invasion of Ireland.
When did Burke's mother die?
A: 1770
Problem: Please answer a question about the following article about Carnival:
Several Germanic tribes celebrated the returning of the daylight. A predominant deity was during this jubilee driven around in a noisy procession on a ship on wheels. The winter would be driven out, to make sure that fertility could return in spring. A central figure was possibly the fertility goddess Nerthus. Also there are some indications that the effigy of Nerthus or Freyr was placed on a ship with wheels and accompanied by a procession of people in animal disguise and men in women's clothes. Aboard the ship would the marriage of a man and woman be consummated as a fertility ritual.
Whose effigy was placed on a ship on wheels?
A: Nerthus or Freyr
Problem: Please answer a question about the following article about Catalan language:
During much of its history, and especially during the Francoist dictatorship (1939–1975), the Catalan language has often been degraded as a mere dialect of Spanish. This view, based on political and ideological considerations, has no linguistic validity. Spanish and Catalan have important differences in their sound systems, lexicon, and grammatical features, placing the language in a number of respects closer to Occitan (and French). 
What has Catalan often been considered?
A: dialect of Spanish
Problem: Please answer a question about the following article about Lighting:
Track lighting, invented by Lightolier, was popular at one period of time because it was much easier to install than recessed lighting, and individual fixtures are decorative and can be easily aimed at a wall. It has regained some popularity recently in low-voltage tracks, which often look nothing like their predecessors because they do not have the safety issues that line-voltage systems have, and are therefore less bulky and more ornamental in themselves. A master transformer feeds all of the fixtures on the track or rod with 12 or 24 volts, instead of each light fixture having its own line-to-low voltage transformer. There are traditional spots and floods, as well as other small hanging fixtures. A modified version of this is cable lighting, where lights are hung from or clipped to bare metal cables under tension.
Who invented track lighting?
A:
Lightolier
