The Great Fire of London started in the very early hours of September 2,1666. In four days it destroyed
more than three quarters of the old city, where most of the houses were wooden and close together. One
hundred thousand people became homeless, but only a few lost their lives.
The fire started on Sunday morning in the house of the King' s baker (面包师) in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from
the bakery(面包房)into a small hotel next door. Then it spread quickly into Thames Street. That was the
beginning.
The underlined word "family" in the second paragraph means _____.
A. home
B. children
C. wife and husband
D. wife and children
