Rome faced constant attack after the pax romana because its army?
a. was becoming less loyal to the emperor.
b. was becoming more loyal to the emperor.
c. had trouble paying mercenaries to fight.
d. had trouble finding mercenaries to fight

I think it was D.  The Roman army was no longer composed of the disciplined troops that built the empire but instead relied on mercenaries.  They were not loyal troops but fought for money and treasure.  Apart from that was the lack of military leaders who were capable devising tactics to defend the Empire.

hr2520 is the patient's act. there is required the secretary of health to summon a committee to develop a national strategic plan of prevention. this committee has forth provisions that make possible for the govern entities to acquire private health insurance services.

is easier to keep this hr2520 as federal, because that way the secretary of health has centralized power to deal with private insurance companies and the federas government has more ways and power to negotiate with them, than doing this process state by state in their specific terms.
