It has been edited to "average educated European". If going by tertiary education, that is about 30% to 35% of the European population. I wouldn't be surprised if that group speaks three languages. In Spain it is typical to speak three of Spanish, Catalan, Valencian, Galician, Basque, Portugese, Arabic, English. In The Netherlands basically anyone speaks Dutch and English plus a third language, usually Frisian, Limburgish, German, French, Spanish, Turkish or Arabic.
