The correct answer is A) building shelters.
The pioneers’ first priority was building shelters.
Life was difficult for pioneers who decided to leave their former lands and travel to the west in the time if US history called "the westward expansion." The Oregon Trail was also a difficult road to cross. Many people could complete it. Hunger was a major issue.

The correct answer is: " the tetrarchy"
Diocletian was the Roman Emperor between years 284 and 305. During this reign, he managed to stabilize the empire and brough the so-called Crisis of the Third Century, to an end.
Diocleatian decided to appoint Maximian as co-emperor, so that he would rule the Eastern side of the Empire while Maximian would rule the Western one. Each of them appointed a junior co-emperor, who operated under their command, so <u>it ended up becoming a "rule of four" or tetrarchy, and each ruled a quarter fraction of the empire. </u>
