While the population of city X is approximately one-half that of city Y, the number of city X residents who are patients in hospitals is only one-fourth that of the number of city Y residents who are patients in hospitals.
Why is the ratio of X residents who are patients in hospitals to Y residents who are patients in hospitals lower than the ratio of X’s population to Y’s population?
This is an EXCEPT question. The four wrong answers should suggest a potential difference between X’s residents and Y’s residents that could lead to X’s residents being less likely to go to the hospital. For example, maybe X’s residents are healthier than Y’s residents, or maybe X’s residents have worse access to hospitals than Y’s residents.
