Input: Read this: In 550 BC, Cyrus the Great, son of Mandane and Cambyses I, took over the Median Empire, and founded the Achaemenid Empire by unifying other city states.

Question: Who founded the Achaemenid Empire when the city states in Iran came together in unification?

QUES: In 1996, Marvel had some of its titles participate in "Heroes Reborn", a crossover that allowed Marvel to relaunch some of its flagship characters such as the Avengers and the Fantastic Four, and outsource them to the studios of two of the former Marvel artists turned Image Comics founders, Jim Lee and Rob Liefeld. The relaunched titles, which saw the characters transported to a parallel universe with a history distinct from the mainstream Marvel Universe, were a solid success amidst a generally struggling industry, but Marvel discontinued the experiment after a one-year run and returned the characters to the Marvel Universe proper. In 1998, the company launched the imprint Marvel Knights, taking place within Marvel continuity; helmed by soon-to-become editor-in-chief Joe Quesada, it featured tough, gritty stories showcasing such characters as the Inhumans, Black Panther and Daredevil.
When was Image Comics founded?

Nigeria is a Federal Republic modelled after the United States, with executive power exercised by the president. It is influenced by the Westminster System model[citation needed] in the composition and management of the upper and lower houses of the bicameral legislature. The president presides as both Head of State and head of the national executive; the leader is elected by popular vote to a maximum of two 4-year terms. In the March 28, 2015 presidential election, General Muhammadu Buhari emerged victorious to become the Federal President of Nigeria, defeating then incumbent Goodluck Jonathan.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many times can a Nigerian president be elected?
Ah, so.. two 4-year terms

Question: Arabic translation efforts and techniques are important to Western translation traditions due to centuries of close contacts and exchanges. Especially after the Renaissance, Europeans began more intensive study of Arabic and Persian translations of classical works as well as scientific and philosophical works of Arab and oriental origins.

Try to answer this question if possible: What would Western traditions eventually avoid?
Answer: unanswerable

Input: Read this: During the early 20th century it became increasingly common to bury cremated remains rather than coffins in the abbey. In 1905 the actor Sir Henry Irving was cremated and his ashes buried in Westminster Abbey, thereby becoming the first person ever to be cremated prior to interment at the abbey. The majority of interments at the Abbey are of cremated remains, but some burials still take place - Frances Challen, wife of the Rev Sebastian Charles, Canon of Westminster, was buried alongside her husband in the south choir aisle in 2014. Members of the Percy Family have a family vault, The Northumberland Vault, in St Nicholas's chapel within the abbey.
Question: What family has the Northumberland Vault?

Output:
Percy Family
