This is a question I got from a reader, an anonymous reader, and the subject line just said, "Urgent," and this was the entire email: "If people had wheels and could fly, how would we differentiate them from airplanes?"
Asta e o întrebare de la un cititor, anonim, iar subiectul era ,,Urgent", iar mailul era: ,,Dacă oamenii ar avea roţi şi ar putea zbura, cum i-am deosebi de avioane?"
