Answer:
A. Fred once lived in Pittsburgh
Explanation:
When both Fred and Greta arrived in Pittsburgh, both had differing reactions to that place. Fred being happy to be there shows that he used to live there before he moved to another city and being back, he'll visit old friends. Greta, on the other hand, is rather reluctant to be there. She dreads it. the paragraph shows that Fred once lived there in Pittsburgh, for it is only possible to have old friends where one used to live. No one can have old friends if he/she hadn't lived there before.
