单选题 Roger: Hey Andrew, we've just received that order of books from MacPherson. Andrew: Great news. They finally got here. ______. Roger: Yes, they said the ship got held up in Bombay. Anyway, they're here now.

A、 Did the deliverers give any explanation about the delay?
B、 I didn't expect them to arrive here so soon.
C、 There isn't any damage to the shipment. Thank goodness!
D、 It really took a long time. Well, what happened?

【正确答案】 A

【答案解析】Roger的最后—句指出了MacPherson Co. 送书延期的理由，由此可知上文提问的是书为什么会延期。因此选项A正确。句中 "they said" 和选项A中的 "the explanation" 相对应。
