Task: Question Answering
Input (English): Passage: When I decide it is time to leave my house , it is quite an ordeal . I am limited physically , and it requires more to do this than it has in my past . I must get up and get my clothes laid out , then go lie down .  After this , I get up and get dressed , then lie down . The reason for all of this lying down is because if I am up long , my blood pools downwards and I can pass out , due to a problem with my nerves . I then get a cane due to some back issues , and make sure I have my keys in my purse .  I close the door , and then take out my keys and lock the deadbolt . The windows and back door of my house are always locked . Then I can leave . Question: What did they lock? Option1: their back door Option2: their front door
Output (English): their front door
