Hi, AnnBar,
Good question. Let's address both aspects of your question separately.
First, answer choice (A) has a couple defects. As you noted, the scope of (A) is too narrow: it deals only with the initial part of the discussion. In addition, the author of this passage is not contesting the larger consensus that alcohol in general has deleterious health effects. Instead, the author contests this blanket conclusion as it pertains to the health benefits of wine, which the author argues is the exception rather than the rule.
Second, let's discuss your approach on "main point" or "primary purpose" questions. In general, if you're having trouble with such problems, consider perhaps choosing a different problem or different problems to answer first on reading comprehension passages. For example, consider choosing very detail-oriented questions ("According to the passage, which of the following..." or "Which of the following does the passage identify as a feature of..." &c.). In your close-reading in the passage to find evidence to answer these questions you may improve your understanding of the overall main point of the passage.
When you do a main point question, make sure that you generate a strong prephrase. In your own words, try to provide a brief synopsis of the entire point of the passage: what's it about? what's the author's point of view about this subject? what happens in each part of the passage, and how does everything fit together?
Focus on using your prephrase to compare to answer choices. Separate the options into contenders and losers. When you're left with two (or maybe three) contenders, focus on the differences between these answers. In this case, we can see the difference in scope or the factual error in answer choice (A). Try to keep your focus narrow. If you can find something wrong with an answer choice, eliminate it. Focus on eliminating answers because they're incorrect rather than arguing for why you like answers.
I hope this helps!
