Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct  answer  to  each  of  the questions from 36 to 42.

The Census Counts!

          Every ten years there is a national census to count the number of people. The census counts the number of people in each area, the number of men and women, their ages, their profession, their family size and status. The census is the only way to count everyone. Its results are used by a great many people and are available to everyone. The census is useful; it helps to work  out present and future needs for housing by seeing how many people are housed now, or the sizes and ages of their families. In addition, the size of annual grants made by the Government to  public services depends largely on the numbers and needs of people in the area provided by the census. Furthermore, the census shows how many people have moved from one area to another and how the number of the local work force is changing.

          The census is taken in order to provide the figures about the nation as a whole. It does not give information about any named person, family or household. Therefore, names and addresses are needed on the forms but they are not fed into the computer. After the census, the forms with the names on are locked away and will not be released to anyone outside the Census Office for 100 years. The answers people give on their census forms will be treated in strict confidence. Everyone working on the census is sworn to secrecy and can be sued if he or she improperly reveals information

A. completely

B. very much

C. a little

D. not at all
