Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it.

In the world today we make health an end in itself. We have forgotten that health really means to enable a person to do his work and do it well. A lot of modern medicine, and this includes many patients as well as many physicians, pay very little attention to health but very much attention to those who imagine they are ill. Our great concern with health is shown by the medical columns in newspapers, the health articles in popular magazines and the popularity of television programmes and all those books on medicine. We talk about health all the time. Yet for the most part the only result is more people with imaginary illness. A healthy man should not be wasting time talking about health : he should be using health for work.


A healthy man should be concerned with

A) his work which good health makes possible B) looking after his health
C) his health which makes work possible D) talking about health
 
Answer & Explanation Answer: A) his work which good health makes possible
