答案：C
答案句：Panda Gourmet offers online ordering for takeout, and delivery is now an option.
参考译文：Panda Gourmet提供在线订购外卖，现在也可以配送。
定位线索：题干“only at Panda Gourmet”→答案句取自Panda Gourmet段落“Panda Gourmet offers online ordering for takeout, and delivery is now an option”；文中“delivery”对应选项C“Takeout delivery”。
解析：题干问Panda Gourmet独有的服务，答案句明确指出其提供“delivery”（配送），其他餐厅均未提及此服务，因此选C。A项“Call-in orders”是Shanghai Taste的服务，B项“Free packing”文中未提及，D项“Online pickup orders”是Gourmet Inspirations的服务，均非Panda Gourmet独有。

答案句：Dinner hours: Tuesday through Thursday 5:30 p.m. — 9:00 p.m. (last seating); Friday and Saturday 5:00 p.m. — 9:30 p.m. (last seating). Closed on Sunday and Monday.
参考译文：晚餐时间：周二至周四下午5:30至晚上9:00（最后入座）；周五和周六下午5:00至晚上9:30（最后入座）。周日和周一休息。
定位线索：题干“Cantonese restaurant in Columbia Heights”→答案句取自Queen’s English段落“Dinner hours...”；文中“Dinner hours”对应选项D“It serves only dinner”。
解析：题干问哥伦比亚高地的粤菜餐厅（即Queen’s English）的情况，答案句只提到晚餐时间，且明确“Closed on Sunday and Monday”，说明该餐厅只供应晚餐，选D。A项“only on weekdays”错误，因为周五周六也营业；B项“no-pet policy”与文中“dog-friendly patio”矛盾；C项“takes no reservations”与文中“Reserve a spot”矛盾。
