Task: Question Answering
Input (English): Passage: Every Christmas , I buy a Christmas tree from a tree lot for my family . This year , we went to Christmas Trees A Plenty on Main Street because we heard they had a great deal . Before we went , I had my husband measure the space in the living room where the tree would go , and measure our ceiling , to make sure that we did n't get a tree that would be too big . Then everyone got in the truck , put on their seat belts , and I drove us to the tree lot . There were dozens of trees on the lot and everyone went off to look for trees that they liked . I knew that we were looking for a tree that had a good shape , healthy looking pine needles , and was just the right size . I found the perfect tree and I hollered for my family to come look . We took the tree tag from the tree and went to the attendant . They confirmed the price was $ 150 , and I got out my wallet and paid for the tree . Then they gave us our receipt , and they had an attendant help my husband strap the tree into our truck . Question: When did they purchase the tree? Option1: After confirming the price Option2: After measuring the ceiling
Output (English): After confirming the price
