Part A
Write a short expository essay (about 120 words) to explain the main points of the following piece of information.
First aid is emergency treatment for illness or injury while waiting for medical help. At one time or another almost everyone is called upon to render first aid. Unless she or he has taken a course on the subject, there is usually confusion and doubt as to what should be done. In most cases it is better for the person untrained in first aid to do too little than too much. If it is not possible to reach a doctor, police or firemen are better equipped to give first aid than are the uninitiated.
It is advisable for at least one member of the family to take a FIRST AID course, and it is a necessity for each household to have a good emergency medical manual and a first-aid kit. Always keep in mind that first aid does not replace the doctor but merely attempts to keep the victim alive and in the best condition possible until medical aid arrives.
