资料题：Which of the following statements is correct（　）。

English people traditionally like to live in small houses, not apartments which they call flats.The usual building material is red brick.Houses built before 1910 were very often arranged in long uniform room or terraces, with no gap between the houses, and with each house containing a front room and a bathroom an each a of its two floors, with perhaps a small room above the entrance hall.In central areas of towns, some bigger houses had more floors, but even a house with four floors was usually on the same basic pattern, with a basement for servants and the top rooms for the children.Houses standing alone in their own grounds were normally very large and,until 1850, a very pleasant design.Another fairly wide-spread arrangement, for the moderately wealthy, was the semi-detached house, usually still on the same basic arrangement but with houses built in pairs and some space left between the pairs.This type is now more usual than the uninterrupted terrace.
