Which of the following is true?

参考解析：

细节理解题。根据第二段第四句和第五句“Joe only had one piece of good meat in the shop. He had sold all the rest earlier in the day.”可知，肉没有全部被买走，还剩一块。所以A项错误。根据文中最后一句“Give me both of them, please”可知，这位女士两块肉都想要买走，所以B项错误，D项正确。根据第三段倒数第三句“Joe went into the room behind his shop, opened the refrigerator, put the piece of meat into it, took it out again and shut the door of the refrigerator with a lot of noise.”可知，Joe先把肉放回冰箱中，之后又拿出来，并故意制造打开冰箱拿肉的假象，所以Joe拿出的是同一块肉，C项错误。故选D。
