In one study, people who owned dogs reported walking significantly more each week than people who did not. The researchers cautioned that the study did not show that owning a dog causes people to walk more, since people who already enjoy walking may simply be more likely to get dogs. ______ the findings suggest that dog ownership and physical activity are linked in some way, a connection that future studies could investigate.
Which choice completes the text with the most logical transition?
As a result,
Even so,
For example,
Likewise,
Answer: B
The middle sentence limits what the study shows: it doesn't prove that dogs cause more walking. The final sentence says the findings still show some link. "Even so" introduces a point that holds true despite the limitation just mentioned. "As a result" would wrongly suggest that the caution is what produced the link.
"As a result" may seem to fit because the final sentence states a conclusion, but that conclusion holds despite the researchers' caution, not because of it.
