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

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

1) Agricultural societies cannot exist without staple crops.

2) Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental food

3) All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams.

4) Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there. <-- conclusion

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
- I'll go with this one. If they did not develop any other staple crops other than rice and yam, then based on the earliest date when both crops were introduced, the time agricultural societies rose there could be determined.

B. There are no plants native to western Africa that, if domesticated, could serve as staple food crops.
- If so, then the staple crops will have to be introduced, but they need not be yam and rice, two crops which the conclusion is based on. So this is out.

C. Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa
- Does not have to mean these societies wil move to western Africa

D. Kola and okra are better suited to growing conditions in western Africa than domesticated rice and yams are
- Not useful. Not suited to western africa does not rule out that the crops can be planted (it might be more difficult to cultivate them, but it's not impossible)

E. Kola and okra were domesticated in western Africa before rice and yams were introduced there
- Not useful

A is best.

I will go with A

A. People in western Africa did not develop staple crops that they stopped cultivating once rice and yams were introduced
If people had developed some other stape crop before rice and yams were introduced then we cannot establish the earliest date at which agricultural societies could have arisen.

C. Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa.
This does not link to the conclusion which states "discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there.

after i finished the passage, My rethinking was : the conclusion "discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there" would not be true if Western Africa have another staple corps before getting the rice and rams. so my assumption was: Western Africa didn't plant other staple plants before receiving the Rice and Yams. but i couldn't find something similar to my rethinking among the answer choices. My problem was : the way they wrote answer A is very weird so i couldn't realize that "A" is the same as my rethinking.

Answer A : "People in western Africa did not develop staple crops [u]that they stopped cultivating[/u] once rice and yams were introduced"
i couldn't understand this phrase "that they stopped cultivating"

Any advice to how can i understand unclear answers in future ?

thanks

Hello friend,

even m failing to understand wat it actually meant...!

it mite mean like-

people dint develop any staple crop wich they could even stop being cultivated..!

just a guess but the sentence seems to be very wordy and this perhaps may b the only meaning inferred from that phrase..!








please consider kudos if agree with my post :)
