Passage 1

   Cats have been on the official payroll of the British Post Office for more than a century. They are not hired to sort or deliver mail, of course but to keep letters from being eaten by mice.

  The problems were very bad in London in the mid-1800s, when mice invaded the mail-sorting rooms. Traps and poisons proved ineffective, and in 1868 the Secretary of the Post Office approved the hiring of three female cats at a weekly allowance of two cents each. Within months the rodent population had shrunk dramatically, and the post offices received the go-ahead to hire. Many did and, as felines become more prominent in the work force, their pay improved. In 1953 the Assistant Postmaster General assured the House of Commons that female mouse-hunters received “very adequate” maternity benefits and enjoy the same wages and employment opportunities as male cats.

  Today cats are on the payroll of at least three London postal sites, at an average wage of $ 1.60 a week.

Passage 2

   Some scientists think that one of the causes of alcoholism is a poor diet. They found that mice craved alcohol when they were given foods low in vitamin B.

  At first, all of the mice in the experiment were put on the same diet. This diet was neither high nor low in vitamin B. the mice were given a choice of four liquids to drink. One was water and the other three were alcohol solutions. The alcohol concentration in the liquids ranged from the level found in beer to the level found in whiskey. Despite the fact that all of the mice ate the same food, they chose different liquids to drink. Some of them became alcoholics and some did not.

  The scientists then gave food that was lower in vitamins and minerals than their original diet. The first group of mice stopped drinking whiskey and began to drink water. The second group stopped drinking water and began to drink whiskey. When vitamin B was added to the second group's diet, they again chose water and seemed to have no need for alcohol.
