As regards social conventions, we must say a word about the well known English class system. This is an embarrassing subject for English people, and one they tend to be ashamed of, though during the present century class-consciousness has grown less and less, and the class system less rigid. But it still exists below the surface. Broadly speaking, it means there are two classes, the "middle class" and the "working class". (We shall ignore for a moment the old "upper class", including the hereditary aristocracy, since it is extremely small in numbers; but some of its members have the right to sit in the House of Lords, and some newspapers take a surprising interest in their private life.) The middle class consists chiefly of well to do businessmen and professional people of all kinds. The working class consists chiefly of manual and unskilled workers.
The most obvious difference between them is in their accent. Middle class people use slightly
A. are extremely small in number so that media pays no attention to them
B. still uses old words like "sir" in their everyday life
C. includes the hereditary aristocracy
D. refers only to the royal family
