A select discography of recordings of Chopin works by pianists representing the various pedagogic traditions stemming from Chopin is given by Methuen-Campbell in his work tracing the lineage and character of those traditions.

Input: Read this: The hole walls for boards with two or more layers can be made conductive and then electroplated with copper to form plated-through holes.  These holes electrically connect the conducting layers of the PCB. For multi-layer boards, those with three layers or more, drilling typically produces a smear of the high temperature decomposition products of bonding agent in the laminate system. Before the holes can be plated through, this smear must be removed by a chemical de-smear process, or by plasma-etch. The de-smear process ensures that a good connection is made to the copper layers when the hole is plated through. On high reliability boards a process called etch-back is performed chemically with a potassium permanganate based etchant or plasma. The etch-back removes resin and the glass fibers so that the copper layers extend into the hole and as the hole is plated become integral with the deposited copper.
Question: What connects the conducting layers of the PAB?

Output: unanswerable


Input: Read this: RIBA runs many awards including the Stirling Prize for the best new building of the year, the Royal Gold Medal (first awarded in 1848), which honours a distinguished body of work, and the Stephen Lawrence Prize for projects with a construction budget of less than £500,000. The RIBA also awards the President's Medals for student work, which are regarded as the most prestigious awards in architectural education, and the RIBA President's Awards for Research. The RIBA European Award was inaugurated in 2005 for work in the European Union, outside the UK. The RIBA National Award and the RIBA International Award were established in 2007. Since 1966, the RIBA also judges regional awards which are presented locally in the UK regions (East, East Midlands, London, North East, North West, Northern Ireland, Scotland, South/South East, South West/Wessex, Wales, West Midlands and Yorkshire).
Question: What was the last year in which RIBA's Royal Gold Medal was given?
