Question 2 is based on the news report you have just heard.

（1）A message in a bottle sent out to sea by a New Hampshire man more than five decades ago was found 1,500 miles away and has been returned to his daughter. The long lost message was discovered by Clint Buffington of Utah while he was vacationing. Buffington says he found a soda bottle half-buried in the sand that looked like it had been there since the beginning of time. The note inside the bottle said, “Return to 419 Ocean Street and receive a reward of $150 from Richard and Tina Pierce, owners of the Beachcomber motel.” The motel was owned by the parents of Paula Pierce in 1960. Her father had written the note as a joke and had thrown it into the Atlantic Ocean. Buffington flew to New Hampshire to deliver the message to Paula Pierce. （2）She held up to her father’s promise giving Buffington that reward, but the biggest reward is the message in a bottle finding its way back home. 

2. Why did Paula Pierce give Clint Buffinton the reward?

解析：B。根据新闻结尾可知，Paula Pierce此举是为了信守父亲许下的承诺。B项中的 honor her father’s promise是对原文中held up to her father’s promise的同义转述。
