【正确答案】 A

【答案解析】[解析] 13-15 Sunday's fire at a New York social club in which 87 people died is now believed to be the worst in the city in almost 80 years. The police say a man has been charged with murder and arson. Here, Mike Knott reports: "The fire, which killed 61 men and 26 women, tore through the Happy Land Club in the Bronx area of New York in the early hours of yesterday morning. Most of the dead were trapped on the top floor of the 2-storey building and were smothered by smoke and fumes. Police have arrested 36-year-old Julio Gonzalez who lives nearby. He is said to have had an argument and a fight at the club shortly before the fire started. The mayor of New York, Davis Dinkins, was at the scene early yesterday and said it was the most terrible sight he'd ever seen. After four hours of meeting with police, fire officers and city officials, Mayor Dinkins announced the formation of a new Social Club Task Force to review the safety of all 700 night clubs in the city. The Happy Land Club had been inspected 3 months ago and ordered to close because of inadequate safety standards. And the Mayor announced there were a hundred and seventy clubs in New York in a similar position and that all would be inspected immediately. He also said he would introduce tough legislation to prevent a similar tragedy from happening again. 13. What caused the deaths of most of the victims?
