        Three years ago, a couple was enjoying a meal at a beach restaurant. (5) [The restaurant was built on a wooden structure above the sea-water.] During the meal, the man’s wedding ring slipped off his finger. It fell through the wooden floorboards apparently lost forever. (6) [Recently, the restaurant manager Ryan Krivoy decided to replace the wooden deck,] and he found an old gold coin, some $100 bills and a silver wedding ring while replacing the deck. (7) [The restaurant’s waitress, Sasha Formika posted a picture of the ring on Facebook.] The post was shared about 5,000 times. 3 days later, the happy wife called to claim the ring. She even texted pictures of her and her husband eating there in 2017 as proof. The restaurant mailed the ring back to the happy couple. Meanwhile, Krivoy discovered that the gold coin was very rare. It was from 1855 and worth as much as $2,000.

7. What did the waitress do about the recovered ring?

解析：C。录音中提到，餐厅服务员萨莎·弗麦加在脸书上发布了这枚戒指的照片。C项与此内容相符，其中posted、picture和Facebook原词复现，故C项为正确答案。

错项排除：A项利用录音中的$2,000进行干扰，但录音中是说旧金币价值2000美元，并不是戒指，故A项排除。录音中并未提及服务员将戒指交给经理，故B项排除。录音中说是妻子打电话认领戒指（claim the ring），并不是服务员直接将戒指交还失主，故D项排除。
