Hello @tomgbean,

The problem with D is that we do not know if accuracy of responses has any effect on sales and profits. We have no information about this. Just because the responses aren't always accurate, it doesn't explain why their profits would have gone down during the study.

C is better, because it tells us that surveys don't cause a decline in profits, but rather they are in indicator of declining profits. This businesses that are doing well are not receiving complaints, so they are not using surveys. The businesses that are struggling are receiving complaints, so they issue a survey. This explains the difference between the two groups examined in the study.
