Which of the followings is NOT TRUE about Stephanie Evans?

参考解析：

细节理解题。根据文章第三段“‘I hated the way the clutter made me feel but I just couldn’t throw anything away — even if something broke, I couldn’t part with it,’ says Stephanie, 51, a teaching assistant from Birmingham”可知，51岁的斯蒂芬妮（Stephanie）是伯明翰的一名助教，但并不能说明“她当助教已有51年了”，且她没办法扔掉任何一样东西，所以A项正确，C项错误；根据第二段第一句“As a result, her hallway and living room were crammed with towering stacks of books and magazines.”可知，她家的门厅和客厅堆满了高高摞起的书本杂志，所以B项正确；根据第六段第一句“When I stepped outside the front door, no one would have guessed that I was living in such chaos”可知，走出家门后，没有人知道她的居住环境是这样的，所以D项正确。故选C。
