The people s migrations spread culture across medieval africa.
a. yorba
c. bantu
b. portuguese
d. ndongo

C is the correct answer.

Explanation:

Bantu is made up of two terms. Ba means people, while ntu means life force. It is the cultural and linguistic group of people which originated around present-day Nigeria, West Africa, and Cameroon. Bantu people migrated to central, southern and eastern Africa for 2,000 years. Streams of Bantu people over a vast territory and equally large periods constituted the largest migratory flows in the history of humanity. Their origin is unclear. The eastern branch of Bantu people migrated to Zimbabwe and Mozambique while the western branch migrated to Angola, Namibia and Northwest Botswana.

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:
