According to the lesson, what can we understand about North America tribes from their burial mounds? They had expedient ways of burying their dead.
They didn't use a house more than once.
They seemed to want to escape their dead by just covering them up then leaving them behind.
They covered their dead with enormous amounts of earth, either in houses or on high grounds near their villages.

The North American Mound Builders constructed earthen mounds; the mounds of the Ohio River valley served as graves, and other mounds served as temples, such as those in Illinois.

The answer is is the first one: They had expedient ways of burying their dead

I think, hope this helps. ^-^

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
