The Council does not have executive powers but meets biannually to discuss issues of mutual importance. Similarly, the Parliamentary Assembly has no legislative powers but investigates and collects witness evidence from the public on matters of mutual concern to its members. Reports on its findings are presented to the Governments of Ireland and the United Kingdom. During the February 2008 meeting of the British–Irish Council, it was agreed to set up a standing secretariat that would serve as a permanent 'civil service' for the Council. Leading on from developments in the British–Irish Council, the chair of the British–Irish Inter-Parliamentary Assembly, Niall Blaney, has suggested that the body should shadow the British–Irish Council's work.
What does the British-Irish Council do?
A: investigates and collects witness evidence

The club's original crest was a quartered diamond-shaped crest topped by the Crown of Aragon and the bat of King James, and surrounded by two branches, one of a laurel tree and the other a palm. In 1910 the club held a competition among its members to design a new crest. The winner was Carles Comamala, who at the time played for the club. Comamala's suggestion became the crest that the club wears today, with some minor variations. The crest consists of the St George Cross in the upper-left corner with the Catalan flag beside it, and the team colours at the bottom.
Who was the winner of the crest competition? 
A: Carles Comamala

What is the relationship that is avoided in a navigational model?
