To what does "they" refer?
Physicians and health workers.
Then probably the best answer is 2), although it's not clear because we don't see the context of this sentence.
Physicians and health workers in the field also teach the public about health and hygiene. They emphasized the importance of good maternal and child health care, including the administering of vaccines.
Ahh! Thank you. Now the sentence makes more sense.
The answer is 2.
thank you :D
You're welcome.
