<s>[INST] The next text is a question of a member of the European parliament:"The Greek Government has decided to extend the existing Athens underground railway line from Ethniki Amyni, its current terminus, to Stavro Aghias Paraskevis, in order to facilitate connections with Athens's new airport. The government claims that for reasons of speed and economy it has decided to dispense with four of the five originally planned stations in the new section of the extension, which would have served the districts of Holargos, Aghias Paraskevis etc.  Additionally, it appears that the Community appropriations which will be used to fund this extension have already been authorised for use on the extension of the underground railway to Aigaleo, aprimarily working-class area of Athens, whose railway line has been postponed until much later. This would amount to sacrificing connections for impoverished areas of the city to an attempt to serve the airport; it should, however, be pointed out that the utility of this attempt is highly questionable, since the planned Stavro station is several kilometres away from the airport.  Has the Commission been informed of these important changes, and what is its assessment of them?"
