Passage

Most scientists who study the physiological effects of alcoholic beverages have assumed that wine, like beer or distilled spirits, is a drink whose only active ingredient is alcohol. Because of this assumption, these scientists have rarely investigated the effects of wine as distinct from other forms of alcoholic beverages. Nevertheless, unlike other spirits but also study only the excessive or abusive intake of these beverages—have obscured.

Recently, a small group of researchers has questioned this assumption and investigated the effects of moderate wine consumption. While alcohol has been shown conclusively to have negative physiological effects—for example, alcohol strongly affects the body’s processing of lipids (fats and other substances including cholesterol), causing dangerous increases in the levels of these identical results whether the wine was white or red. What could explain such apparently healthful effects?

For one thing, the studies show increased activity of a natural clot-breaking compound used by doctors to restore blood flow through blocked vessels in victims of heart disease. In addition, the studies of wine drinkers indicate increased levels of certain compounds that may help to prevent damage from high lipid levels. And the concentration of certain natural compounds found in grapes and not present in other alcoholic beverages.

Answer choices

  1. Out of Scope: method of treatment2% picked this

    advocating a particular method of

    It's hard to see what we would match up with "method of treatment". The author is saying, "Most alcohol researchers have not previously studied wine as distinct from other alcoholic beverages, but they should, since wine actually has some healthful effects, due to the grapes." We might say the author is advocating that alcohol researchers treat wine as distinct from other forms of alcoholic beverages, but that would still be too narrow to capture the main thrust of the passage. The main thrust is, "Check it out, y'all -- new research shows that wine is good for the heart, most likely because of chemical compounds from the grapes that are used."

  2. Out of Scope: popular opinion4% picked this

    criticizing popular

    There isn't really any discussion of popular opinion, and the author's main thrust definitely isn't to criticize regular old people. The only mention of popular opinion is in the last sentence of the 1st paragraph, and the author is very much agreeing with that opinion.

  3. Correct86% picked this

    correcting a scientific

    Why this is right

    The passage begins with two statements that sum up the scientific misconception: 1. wine's only active ingredient is alcohol 2. the effects of wine are probably the same as the effects from other forms of alcoholic beverages The passage then pivots away from that in disagreement ... these scientists have obscured the popular wisdom that wine has healthful effects. And then she presents new research that suggests that moderate wine consumption does some great things for the heart. She ends by suggesting that there are certain compounds in grapes that are playing an active role in breaking up clots, decreasing the walls of blood vessels, and making platelets less sticky.

  4. Opposite6% picked this

    questioning the relevance of newly discovered

    This answer makes it sound like the author is undermining the new evidence about wine having healthful effects, but the author is doing the opposite. She's presenting this evidence as though she thinks it is very relevant.

  5. Out of Scope: revolutionary hypothesis3% picked this

    countering a revolutionary

    The idea in the last paragraph that "one of the most important discoveries in modern medicine is the link between lipid processing and premature heart disease" could be considered a revolutionary finding. It's weird to call it a hypothesis, because it sounds like it's way stronger than a guess or theory at this point. Either way, the author is not trying to counter that discovery in any way. She only says, "We now know of a several other things that are linked to heart disease".
