Input: The story of the rise of politician Willie Stark from a rural county seat to the governor's mansion is depicted in the film. He goes into politics, railing against the corruptly run county government, but loses his race for county treasurer, in the face of unfair obstacles placed by the local machine. Stark teaches himself law, and as a lawyer, continues to fight the local establishment, championing the local people and gaining popularity. He eventually rises to become a candidate for governor, narrowly losing his first race, then winning on his second attempt. Along the way he loses his innocence and becomes as corrupt as the politicians he once fought against. When his son becomes paralyzed following a drunk driving accident that kills a female passenger, Stark's world starts to unravel and he discovers that not everyone can be bought off. The story has a complex series of relationships. All is seen through the eyes of the journalist, Jack Burden, who admires Stark and even when disillusioned still sticks by him. Stark's campaign assistant, Sadie is clearly in love with Stark and wants him to leave his wife, Lucy. Meanwhile, Stark philanders and gets involved with many women, taking Jack's own girlfriend, Anne Stanton, as his mistress. When Stark's reputation is brought into disrepute by Judge Stanton (Anne's uncle), he seeks to blacken the judge's name. When Jack finds evidence of the judge's possible wrongdoing, a quarter century earlier, he hides it from Stark. Anne gives the evidence to Stark, who uses it against her uncle, who immediately commits suicide. Anne seems to forgive Stark, but her brother, the surgeon who helped save Stark's son's life after the car crash, cannot. The doctor eventually assassinates Stark after Stark wins an impeachment investigation. The doctor in turn is shot down by Sugar Boy, Stark's fawning assistant. The main plot is a thinly disguised version of the rise of real-life 1930s Louisiana Governor, Huey Long, Long's efforts to blacken the name of Judge Benjamin Pavy, and Long's assassination by the Judge's son-in-law (compared to nephew, as in the film), Dr. Carl Weiss.

Now complete the following example -
Input: After their HIV positive mother's death, Derick and Margaret collect wood and construct a human-length box with wheels. Then, they journey with it from Kampala to Kasangombe in a heartbreaking bid to overcome poverty and experience hope. The journey throws them dangerous experiences on unpredictable Ugandan roads. Their mother's dying wish had set them off on a seemingly impossible journey to find a relative they do not even know. Before her death, she leaves them an envelope addressed to her sister (their auntie) who is married to a hard-working man living in a distant village called Kasangombe with their kids. Ingeniously, Derick creates a coffin using wood he collected from a rubbish dump and adds luggage bag rollers brought by Margaret. On their journey from Kampala City to their aunt's place, they are offered a lift by a seemingly kind man (played by Joel Okuyo Atiku) in a truck who is amazed by their "box". He introduces them to a kid he had taken under his wings relaxing at the back and shows them a photo of a house they can possess if they work for him. At night though, Margaret sees a scary dream where their helper is not exactly as kind as he seemed so she runs out of the truck. Derick follows and the boy throws out their coffin before waving. They walk the rest of the distance. Initially, their uncle (played by Isaac Muwawu) did not want them in his house because he thought they were HIV-infected. Derick overheard him quarrel with his aunt at night and shook Margaret in the morning from another dream (this time beautiful, where both siblings were smiling and enjoying a picnic in a glorious garden with their aunt, uncle, cousins, dead parents and some whites). Derick convinced her to walk away from the home with him but without a reason. 
Question: What's another word for the human-length box with wheels that the siblings construct?
Output: 


Output: coffin
