Task: Question Answering
Input (English): Passage: We are currently potty training my youngest daughter . Last night she wet the bed in her sleep . When she woke up she was covered in urine .  Then I took her pillow , sheets and blankets and threw them in the washing machine . After we got her into new clothes we went to our linen closet to grab her a new pillow case , sheet and blanket . I took her into her room and we pulled the mattress out of her crib together .  She stood on it while it was on the ground and jumped around for a bit , and started to giggle .  After she got off we spread the sheet out over the mattress and folded each corner over the corner of the mattress and put the mattress back into her crib .  She held the pillow case while I stuffed the pillow inside . Once we placed the pillow back in the crib , we spread her blanket over the mattress and tucked the sides into the bed . Question: When did they take the pillow case? Option1: After they washed it. Option2: After she wet the bed.
Output (English): After she wet the bed.
