A study found that most of the strokes diagnosed by doctors occurred in the left side of patients’ brains. This suggests that right-side strokes are more likely than left-side strokes to go undiagnosed since _______.

Summarize Argument: Phenomenon-Hypothesis
The author hypothesizes that strokes in the right side of the brain are more likely to go undiagnosed than strokes in the left side of the brain. Why? Because most strokes diagnosed by doctors are left-side strokes.

Notable Assumptions
The author assumes doctors diagnose more left-side strokes because they correctly identify them at a higher rate, and not for any other reason. In particular, this means assuming strokes are no more likely to occur in the left side of the brain than the right.

A
patients who have strokes typically also have other health problems
This is irrelevant. It doesn’t suggest that other health problems make a right-side stroke harder to diagnose than a left-side stroke.
B
it is very likely that just as many strokes occur in the right side of the brain as in the left side
This strengthens the author’s primary assumption: that left-side strokes are no more common than right-side strokes. It casts doubt on the possibility that left-side strokes are diagnosed more often simply because they occur more often.
C
doctors vary greatly in the accuracy of their diagnoses of strokes
This suggests strokes are often poorly diagnosed—but not that right-side strokes are under-diagnosed. It doesn’t say doctors are better at diagnosing left-side strokes than right-side strokes.
D
the symptoms of right-side strokes tend to be different than the symptoms of left-side strokes
This doesn’t say symptoms of left-side strokes are harder to detect than symptoms of right-side strokes. It suggests that left-side and right-side strokes tend to be diagnosed differently, but not that diagnosing right-side strokes is more difficult.
E
other studies have suggested that a large number of minor strokes go undiagnosed
This is irrelevant. It doesn’t say minor strokes are more likely to occur in the right side of the brain, or that left-side minor strokes are more likely to be diagnosed than right-side minor strokes.
