I choose letter a.  The Maasai.  They settled in East Africa during the mid-19th Century.  They were known for raising cattle as well being formidable warriors who were armed with shield and spear as well as throwing clubs. Even today they still continue their nomadic way of life.

hi there!

moors is essentially another word for muslims.

the moors invaded spain around year 700, during their time ruling spain the muslims promoted religious tolerance (moors tolerated jews who were viewed as outcasts by northerners), the moors as well had a great impact on their language, and architecture (palaces were created).

i hope this !
