For example, PAO write press releases and speeches for politicians (Option a) and establish relationships with members of the media (Option e). They also informe the superior officers about relevant news and are very important to protect classified information from leaking, you could say PAO are like the eyes and the ears of the government, because they see and hear news in order to pass it to their superiors.
