The passage gives us three facts:
1)In the 1920s, doctors advised that everyone over the age of eighteen should consume at least a third of a cup of
pure butter 2)In the 1950s, physicians recommended that a person
smoke a cigarette following each meal
3) Modern physicians would balk at such suggestions, while wholeheartedly recommending dietary habits such as
two glasses of wine per day and more stuff.
What is clear is that every decade or so the prevailing opinion changes. What seems to be true and a good practice may one day be considered a bad habit.
Which of the following is the main point of the passage?(A) The claims and suggestions of modern medicine may one day seem as faulty as those of the past seem to us today.
CORRECT(B) Medicine today puts many more restrictions on an enjoyable lifestyle than it used to.
We cannot say that by reading the passage, but most importantly this is not the point.
(C) Fewer people die from preventable disease now than in the past because of the many advancements of medical study.
We cannot say that by reading the passage.
(D) Cigarettes and high-fat foods such as butter may not be as unhealthy as doctors tell us they are.
We cannot say that by reading the passage.
(E) Modern physicians contradict themselves quite often.
This could be tempting, but the passage begins by stating what physicians said in 1920, contradicted by those in 1950: so modern physicians are not the only physicians that the passage talks about.
