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.

Topic

The unique physiological effects and potential health benefits of wine compared to other alcoholic beverages.

Framework

Challenge Position

Main Point

Most scientists have treated wine as no different from other alcoholic drinks and only studied its harmful effects, but recent studies suggest moderate wine consumption may have unique, beneficial effects on heart health, likely due to compounds found in grapes. (Most Valuable Sentence: End of paragraph 1/start of paragraph 2, where the author pivots—)

P1: The Prevailing Assumption

Most scientists just lump wine in with beer and spirits as if the only thing that matters is the alcohol content, and they've overlooked that wine has, for centuries, been thought to have unique health benefits.

P2: Recent Research Challenging the Assumption

A few researchers decided to study wine separately and looked at moderate wine drinking. They found that alcohol from wine enters the bloodstream more slowly than from spirits, and, even more strikingly, countries with more moderate wine consumption see lower rates of early heart disease. This isn’t just about red wine—white wine shows the same effect. The question is: what’s causing these positive health results?

P3: Theories and Findings on Wine’s Health Effects

New studies show wine drinkers have higher levels of certain helpful compounds, including those that break up blood clots and reduce the effects of bad fats. Researchers have also found that wine can decrease blood vessel wall thickness and reduce the stickiness of platelets—both things that lower the risk for heart disease. Interestingly, similar effects show up when people drink a lot of grape juice, suggesting that grapes themselves, not just the alcohol, might be responsible for these benefits.

23.

Which one of the following, if true, would most strengthen the passage's position concerning the apparently healthful effects of moderate wine consumption?

  1. Correct

    Subjects who consumed large amount

    Why this is right

    We were told that two of the things wine appears to be doing are 1. decreasing thickness of blood vessel walls 2. decreasing platelet adhesiveness The second one seems to be coming from wine, because wine is made from grapes, and people who drink a lot of grape juice have this decrease in platelet adhesiveness. This grape juice study is identified as "the first step in confirming speculation that the healthful effects of moderate wine may derive from natural compounds in grapes". So this answer is strengthening that causal story by saying, "We did another study, and it turns out that people who drink a lot of grape juice also get the effect of decreased blood vessel wall thickness." This strengthens the author's position that the healthful effects of moderate wine come from the fact that it's made from grapes, and grapes have some cool chemical compounds in them.

  2. Subjects who were habitual drinkers

    Opposite

    Beer is not healthy. Wine supposedly is. We would strengthen that picture with differences between them, not sameness. Wine, unlike beer, is supposed to have compounds that prevent damage from high lipids. But this answer makes it seem like habitual wine and habitual beer drinkers have similar lipid levels.

  3. Subjects who drank grape juice

    Wrong Direction

    If grapes lead to greater platelet adhesiveness, then that means that grapes are bad for heart disease. Reducing platelet adhesiveness is supposed to be good for heart disease. This answer basically contradicts the study at the end of the passage "which demonstrated a decrease in platelet adhesiveness among individuals who drank large amounts of grape juice", and that study was supposed to be confirmation of the idea that moderate wine intake is good for you because of the compounds in grapes.

  4. Subjects who drank excessive amounts

    Weakens

    Excessive alcohol is bad for you. Moderate wine is supposedly good for you. If moderate wine drinkers have the same rate of heart disease as do binge drinkers, that makes it sound like moderate wine isn't so healthy.

    2% picked this

  5. Subjects who possess a natural

    No Impact

    Moderate wine intake is supposedly good because it has a natural clot-breaking compound. This answer is saying that sometimes people have a natural clot-breaking compound in them for genetic reasons too. That doesn't have anything to do with wine.
