Four friends, Ali, Joy, Kay, and Lyn, decided to celebrate Kay’s birthday with dinner at the Clever Cafe. Each chose one main course (duck,
beef, pork, or fish) and one dessert (mousse, torte, fruit, or crepe) but
no two chose the same dish. Their surnames, in no particular order,
are Gorman, Foster, Fields, and Devlin. 
Use the following clues to determine their full names and what they had to eat.
1. Joy never eats pork but Ali had crepe.
2. The beef-eater has the letter ‘a’ in her first name.
3. Ms Gorman had fruit dessert but is not the birthday girl.
4. The fish-eater had torte but she wasn’t Ms Devlin.
5. Ms Foster had duck but not mousse.
