The indian appropriations act of 1885 let american indians, a. live freely on unoccupied lands. b. divide their land into 160-acre plots. c. sell their unoccupied territory. d. live confined on reservations.

i beleive a. is the only possible answer

donald carl johanson (born june 28, 1943) is an american paleoanthropologist. he is known for discovering – with yves coppens and maurice taieb – the fossil of a female hominin australopithecine known as "lucy" in the afar triangle region of hadar, ethiopia.

hope this !

i googled "who was kolson johanson" and this is the answer i found.

sorry if this is incorrect.
