An old question but like to discuss:
Agricultural societies cannot exist without staple crops. Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods.
All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams. Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there.
Which of the following is an assumption on which the argument depends?
A. People in western Africa did not develop staple crops that they stopped cultivating once rice and yams were introduced
B. There are no plants native to western Africa that, if domesticated, could serve as staple food crops.
C. Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa
D. Kola and okra are better suited to growing conditions in western Africa than domesticated rice and yams are
E. Kola and okra were domesticated in western Africa before rice and yams were introduced there

C. Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa
The passage is about the staple foods, which are daily essentials. without staple foods, an agriculture society cannot exits. if the date when the rice and yams were introduced in the african societies, then we know when the agricultural societies outside western africa arrived in western afrca.
therefore, the passage has assumed that the outside agricultural societies had already used rice and yams as staple foods before their arrival to western africa. these people took these foods with them because the cannot survive with out those foods.

Hi, your assertion in the blue color part has been claimed in the passage as the fact or evidence. So, it cannot be assumption.
In the passage:......All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams. ................
I think the OA should be A
