Question

We can infer from the first sentence that

• A. not all that has been written on the subject of addiction has added to our understanding
• B. no one can have read all the literature on any drug
• C. the more that is published the more we are likely to understand
• D. the rate of growth should be higher if we are to understand the subject
• E. writing about addiction is fashionable

Answer 1

The correct option is A not all that has been written on the subject of addiction has added to our understanding

Option A is the correct answer. the author has tried to stress that our understanding of addiction has not excelled or improved with the output of literature on the subject. He goes on to state that the definitions being fluid do not help the cause, and that more helpful material needs to be published. The statements of options B,C,D and E are not supported by the text, and thus, are incorrect.
