Given the task definition and input, reply with output. In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. Once you create a question you also need to provide the correct answer for it. Write your answer like "Question: your question, Answer: your answer". The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Short answers containing words that are present in the passage are preferred. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is a factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.

Elia Kazan,who directed the Broadway play on which the black and white film is based, invited Marlon Brando, the male lead, and Kim Hunter and Karl Malden, his supporting cast, to repeat their Broadway triumphs in the film remake.Brando plays Stanley, a poor boy who grew up tainted by ethnic slurs, made financially stable by the fortunes of the second world war. He does well as a blue collar travelling salesman, moves to New Orleans and marries Stella (Hunter), daughter of an Aristocratic MIssissippi family anxious to escape the war;s invitable destruction of her family's land, wealth, property and social status. Stanley has never met his sister-in-law Blanche, the female lead of the play ,Vivien Leigh in the movie remake. Blanche arranges a visit to see her sister in New Orleans and shows up on Stanley's doorstop obviously annoyed that there is neither a guest bedroom for herself nor a master bedroom for her sister and brother-in-law, in their cramped, dingy apartment in a bustling quarter of the city. The tensions of wartime emergency cohabitation of family members somehow forced to move in with each other in tight, cramped quarters because of the fortunes of war are noted when it is obvious that Blanche and Stanley immediately get on each others' nerves, especially when Blanche, who passes herself off as the only Aristocrat in her new neighborhood, is the only one in her new neighborhood who actually resorts to tough bar language and ethnic slurs in passing conversation. This becomes no ordinary domestic quarrel when their tensions escalate beyond a war of words to hurtful, spiteful deeds and then to climatic physical violence. Hollywood icons Marlon Brando and Vivien Leigh are given close, tight photography in their lengthy scenes of escalating conflict, played with such deep insight and such technical brilliance that the audience is given pause, from moment to moment. to decide whether one really has a point and the other should really be apprehended by the authorities. Stanley first wants to know why Blanche seems to be planning to stay for life and what happened to his wife's claim on the family fortune, land, property and social status. Blanche wants Stanley to give up his weekly card game and his weekly bowling tournament with his friends including Mitch (Malden), to stay at home always sweating in his dirtied work clothes because he will have no place to wash and change with a lady in his house, sitting silent like a statue, until he decides it is time to just turn his paycheck over to Stella and move out so Blanche can rule the roost.When Blanche attracts the attention of lonely Mitch who sees the remnants of her Aristocratic upbringing, Stanley investigates, through a friend travelling in Mississippi, why his emotionally disturbed, alcoholic, child molesting sister-in-law was fired from her job and kicked out of her boarding house. A telling interlude has Stanley striking Stella for interfering with his treatment of Blanche. She escapes to the upstairs apartment of her landlady (Peg Hillias), but is so dependent upon Stanley that she returns to him when he goes into the yard and calls for her to come back. Things do not go well for Blanche when Stella goes to the hospital to give birth to her child just after a teenage boy accuses her of making improper advances when he came to her door to collect money for Stanley's periodical subscription and Mitch dumps her. There is surrealistic moment, to be individually sorted out by each viewer, when Blanche insists she is going to cut up Stanley's face with the jagged edges of a broken liquor bottle and then insists he is going to rape her. The play and the movie cuts from the blackout to a scene some time later when Stella is putting her baby to sleep in the front yard, Stanley is having his card game over, and authorities arrive from the local mental institution to put Blanche away for life.The landlady calls Stella to the bathroom, where Blanche is soaking up her cares in another hot water tub and wants the ladies to dress her in her faded, fake finery so a nonexistent gentleman friend can escort her on a nonexistent world cruise. Stella, Mitch and the landlady seem in agreement that Blanche is an innocent flower ravaged by wartime whom Stanley destroyed with his crude bullying.
Question: What does the teenage boy accuse Blanche of?, Answer: Improper advances.
