Recent research indicates that increased consumption of fruits and vegetables by middle-aged people reduces their susceptibility to stroke in later years. The researchers speculate that this may be because fruits and vegetables are rich in folic acid. Low levels of folic acid are associated with high levels of homocysteine, an amino acid that contributes to blocked arteries.

Summary
Some research shows that increased consumption of fruits and veggies reduces susceptibility to stroke later in life. Researchers think this is because fruits and veggies have a lot of folic acid. Low levels of folic acid are correlated with high levels of homocysteine, which causes blocked arteries.

Strongly Supported Conclusions
High levels of folic acid are correlated with low levels of homocysteine, low arterial blockage, and less likelihood of stroke. (The stimulus told us what low levels of folic acid are correlated with as part of an explanation of a potential causal connection between high folic acid and less susceptibility to stroke.)

A
An increased risk of stroke is correlated with low levels of homocysteine.
Antisupported. Low folic acid is correlated with high homocysteine, which blocks arteries. Since researchers suspect that fruits and veggies may lower risk of stroke through folic acid, this means high folic acid should be associated with low homocysteine and low risk of stroke.
B
A decreased risk of stroke is correlated with increased levels of folic acid.
Strongly supported. Researchers think fruits and veggies lower risk of stroke through folic acid. This suggests high folic acid is associated with low homocysteine and lower risk of stroke.
C
An increased propensity for blocked arteries is correlated with decreased levels of homocysteine.
Antisupported. Low folic acid is correlated with high homocysteine, which blocks arteries. This suggests high folic acid is correlated with lower levels of homocysteine and less likelihood of blocked arteries.
D
A decreased propensity for blocked arteries is correlated with low levels of folic acid.
Antisupported. Low folic acid is correlated with high homocysteine, which blocks arteries.
E
Stroke is prevented by ingestion of folic acid in quantities sufficient to prevent a decline in the levels of homocysteine.
Antisupported. High homocysteine is associated with greater arterial blockage. So, lower homocysteine is likely better for reducing stroke than is higher homocysteine. To prevent strokes, we want a decline in homocysteine.
