Question 22 Question 23 Question 24 Question 25 Question 26 Question 27

The author hypothesizes that lycopene reduces the risk of stroke. This is based on a study of 1,000 middle-aged people over a 12 year period, which found that participants with low levels of lycopene were more likely to have a stroke than participants higher levels of lycopene.

The author assumes there’s no other explanation for the correlation between lycopene and reduced risk of stroke.

This suggests a potential alternate explanation for the correlation observed in the study. Maybe what reduced risk of stroke was not higher levels of lycopene, but other nutrients found in fruits/veggies that contain lycopene.

This strengthens the argument by providing evidence that shows the correlation observed in the study is found more broadly, too.

This doesn’t have any impact, since we don’t know whether middle-aged people are more or less likely to have strokes than young adults. Even if we did, this might strengthen, because middle-aged people probably have more strokes.

This might explain how the participants with high levels of lycopene got their high levels of lycopene. But it doesn’t suggest there are alternate explanations for the lower risk of stroke.

We know there was a correlation between higher lycopene and lower risk of stroke. This doesn’t mean everyone had similar levels of lycopene. So, (E) is consistent with the author’s reasoning.
