The correct options are the following:
A goverment is responsible for the welfare of the citizens under its ruling. Therefore, most countries have a public army or military system aimed to protect the country's territory and interests in the international sphere. Moreover, the government is also responsible for designing an economic model in which most of its citizens are able to find a job for a living, and can maintain those who for some specific justified reasons cannot find one. Therefore, a goverment should grant sustenance for its people.
