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.

What this question is testing

Locate Detail

Your task

Pin down exactly what the question asks about the passage — a detail, the author's view, the structure, or the main point — before looking at the choices.

Common trap

Answers that restate a true detail from the passage but don't answer the specific question being asked.

Winning move

Anticipate the answer in your own words from the passage, then find the choice that matches that prediction.

Answer choices

  1. Correct73% picked this

    an increase in the degree to which platelets cause blood

    Why this is right

    Right out of the gate, we've got our answer. It's the opposite of our 4th possibility. - drink wine / eat grapes - less lipids / better lipid processing - decrease thickness of walls of blood vessels - reduce the adhesiveness of platelets Reducing the adhesiveness of platelets reduces the degree to which platelets cause blood to clot (and helps prevent heart disease). This answer is saying an increased degree of clotting would reduce our risk.

  2. Supported8% picked this

    an increase in the body’s ability to remove lipids from

    This matches our 2nd possible detail. - drink wine / eat grapes - less lipids / better lipid processing - decrease thickness of walls of blood vessels - reduce the adhesiveness of platelets

  3. Supported14% picked this

    an increase in the amount of time it takes alcohol to be absorbed

    This one is a bit of a surprise, but it aligns with the 2nd detail. - drink wine / eat grapes - less lipids / better lipid processing - decrease thickness of walls of blood vessels - reduce the adhesiveness of platelets We're told that alcohol in general is dangerous because is causes "dangerous increases" in the levels of lipids. Meanwhile, when people drink wine, the alcohol is absorbed into their bloodstream much more slowly (so there probably wouldn't ever be that dangerous increase .... it's not coming in all at once and overwhelming the body's ability to get rid of its excesses). (The annoying part about this answer is that this detail is meant to show how wine is less-worse than other forms of alcohol. It's not really showing that wine is better than drinking no alcohol at all. So we can only really say that this slower absorption of alcohol could help prevent heart disease if we're handing a drinker a bottle of wine and saying, "drink this instead of your beer or liquor". This slower absorption of alcohol isn't going to help any non-alcohol drinker to prevent heart disease.)

  4. Supported2% picked this

    increased activity of a natural compound that reduces

    Once again, this is dealing with what he hear in the beginning of the 2nd paragraph about lipid processing. - drink wine / eat grapes - less lipids / better lipid processing - decrease thickness of walls of blood vessels - reduce the adhesiveness of platelets "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". Since this clot-breaking compound helps doctors fight the blocked vessels that accompany heart disease, we're assuming that this compound could help prevent heart disease. It's a little weird to assume that something used to treat victims of a disease is also a substance that would help prevent the disease, but if we understand heart disease to be blocked vessels, then a compound that breaks apart clots can reasonably be assumed to help prevent the blocking of vessels.

  5. Supported2% picked this

    increased levels of compounds that prevent damage from high

    This again comes from the beginning of the 2nd paragraph. In addition, the studies of wine drinkers indicate increased levels of certain compounds that may help to prevent damage from high lipid levels. The following sentence explains that high lipid levels have a strong connection to heart disease, so higher levels of compounds that prevent damage from high lipid levels would probably help to prevent heart disease, since heart disease is very linked to lipids.
