单选题
Telephone message

①Sue asked you to inform her of ②whether you are able to join the dinner party celebrating the company's tenth anniversary ③before Friday.
A. The anniversary dinner party will be held on Friday.
B. Sue needs to collect information from you before Friday.
C. You are invited to be present in the anniversary dinner party.

【正确答案】 B
【答案解析】电话留言中提到：“①Sue来电请你告知②能否参加公司十周年庆宴，③请于周五前回复她”。原文中信息点3给出了Sue需要知道收信人能否参加庆宴这一信息的最终时间，并没有明确表明周五要开庆宴，故A项错误。由原文可知Sue只是需要确定收信人是否参加，而不是向其发出确切邀请，故C项错误。只有B项“Sue需要在周五之前收到你的信息”与文意一致。综上所述，正确答案为B。
