Answer:
to keep track of deaths and births in the United States
Step-by-step explanation:
Let's go through this one by one!
1. to set up immunization programs in developing nations
Why would STATE health departments have the responsibility of setting up immunization programs in OTHER nations? that makes no sense so let's cancel this one.
2. to monitor disease outbreaks in other countries
Again why would the state health department's responsiblilty monitor disease outbreaks in OTHER countries? It wouldn't be so let's cancel it.
3. to approve new drugs
It's not the responsibility of the state health department to approve new drugs thats for the FDA to do. So not this one either.
4. to keep track of deaths and births in the United States
Considering this is the only choice left that makes sense this is the right answer, as well as one of the responsibilities of states health departments is to keep track of deaths and births in the states. This is the right choice.
