    What was the probable cause of the fire?Most likely a burning ____.

    正确答案： cigarette
    解析：
    因果关系题。由听力原文中“When we asked the fire chief how the fire started, he answered that most likely a burning cigarette caused it”可以推断，救火队长认为火灾是由点燃的香烟引起的，所以填cigarette。
    【录音原文】
    　　Now back to the news. An early morning fire damaged the historic Geller House today. It destroyed the third floor of the building, but the firefighters saved the first and second floors. There were only a few elderly people living in the building at that time. And they were carried out to safety.
    　　The Geller House was built in 1718 and it was used as a hotel for over 150 years. George Washington stayed there in 1782. Five years ago, it was made into a building for the elderly.
    　　Several fire departments were called to the scene. When we asked the fire chief how the fire started, he answered that most likely a burning cigarette caused it. He promised to make a further investigation into the cause.
    Q11: At what time of day did the fire start?
    Q12: Which floor of the building did the fire destroy?
    Q13: Who lived in the building at the time of the fire?
    Q14: When was the Geller House built?
    Q15: What was the probable cause of the fire?
