Why are a large number of apparently healthy people deemed pre-ill?
Explanation:
From the first paragraph, a majority of apparently healthy people are pre-ill. That is because of chronic degenerative diseases which strike silently. According to the author, there would be a latency period before the symptoms appear and a diagnosis is made. But till that time that apparently healthy person is still ill. We can easily eliminate options 2 and 3, as they do not come close to this idea. Option 4 is a lift from the passage and looks attractive enough. But the option explains about the latency period. The option that answers the question ‘why’ is option 1. “Because so-seemingly healthy people may have chronic degenerative diseases, therefore they are deemed pre-ill.” Hence, the correct answer is option 1.
