At the very end of 2013 , as other newspapers warned of a terrible flood of migrants, The

Economist invited Bulgarians and Romanians to come and work in Britain. So we are【C1】______to report that, since working restrictions imposed when the two countries【C2】______the EU were lifted on January 1st, rather few seem to have【C3】______our offer.
