Answer and explanation:

After doing some deep research on the topic, thinking and coming to a conclusion, I believe the answer for this task is the following: The category of security that had the most volatile annual returns over the period 1926-2016 is the small company stocks.

the correct answer is ''the programs costs have risen dramatically in the recent past'' hope this !

health care plans in the united states having high costs because they are focusing on providing quality programs for different groups of individuals. the quality of the service is based on money flow received from the members. without this investment, couldn't be possible a constant scientific searching to prevent death and illness caused because of low levels of health investigation. currently, the complaints are not about the highest cost, but about the coverage and benefits to access the necessary health services required by the members.  

besides, if a global health system is established the quality levels will fall down because of the standardized of the health. the access to care will increase but the quality will be low because it depends on the money invested.
