When I first started teaching exams for 16 year olds were divided into GCE's and CSE's. Those were not considered capable of learning a foreign language were taught 'Europen Studies'. At the exam one boy refused to write a word, claiming that he did not know any of the answers. A kindly invigilator, noticing this, said, "Surely you can answer this question: 'What kind of wine do we get from Portugal?' The boy persisted in his ignorance, so the teaher repeated the question, stressing the word PORTugal. After a while the boy twigged and said, "Oh, I get it now", and promptly wrote UGAL!
