In addition to re-writing the classification of annelids and 3 previously independent phyla, the molecular phylogenetics analyses undermine the emphasis that decades of previous writings placed on the importance of segmentation in the classification of invertebrates. Polychaetes, which these analyses found to be the parent group, have completely segmented bodies, while polychaetes' echiurans and sipunculan offshoots are not segmented and pogonophores are segmented only in the rear parts of their bodies. It now seems that segmentation can appear and disappear much more easily in the course of evolution than was previously thought. The 2007 study also noted that the ladder-like nervous system, which is associated with segmentation, is less universal previously thought in both annelids and arthropods.[n 2]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What offshoots of polychaetes are only segmented in the rear?
Ah, so.. pogonophores

Switzerland's trade was blockaded by both the Allies and by the Axis. Economic cooperation and extension of credit to the Third Reich varied according to the perceived likelihood of invasion and the availability of other trading partners. Concessions reached a peak after a crucial rail link through Vichy France was severed in 1942, leaving Switzerland completely surrounded by the Axis. Over the course of the war, Switzerland interned over 300,000 refugees and the International Red Cross, based in Geneva, played an important part during the conflict. Strict immigration and asylum policies as well as the financial relationships with Nazi Germany raised controversy, but not until the end of the 20th century.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many refugees did Switzerland intern during World War II?
Ah, so.. over 300,000

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).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the name of the RIBA awards given to professors of architecture?
Ah, so..
unanswerable
