Task: Question Answering
Input (English): Passage: I was on vacation in Spain , where I explored several cities and saw lots of new things . Of course , I brought my camera along to document the trip . After a long day of visiting a very famous cathedral , my camera 's batteries were dying . I opened the battery compartment of the camera and tilted it so that the batteries would fall into my hand . I took care to keep the new ones and old ones from getting mixed up . I handed the dead batteries to my wife so she could throw them out . The battery compartment closed with a snap , and I was ready to take more pictures ! We went out that evening for dinner and a flamenco dancing show , and I was ready with my powered-up camera . Question: When did they pack backup batteries? Option1: After returning to home Option2: before leaving for the vacation
Output (English): before leaving for the vacation
