Question

geographer adebayo oluwole eludoyin and his colleagues surveyed small - scale farmers in three locations in ondo state, nigeria— which has mountainous terrain in the north, an urbanized center, and coastal terrain in the south— to learn more about their practices, like the types of crops they mainly cultivated. in some regions, female farmers were found to be especially prominent in the cultivation of specific types of crops and even constituted the majority of farmers who cultivated those crops, for instance,
female farmers as a percentage of
ondo state region
north ondo
central ondo
south ondo

which choice most effectively uses data from the graph to complete the example?
a most of the farmers who mainly cultivated cereals and most of the farmers who mainly cultivated non - root vegetables in south ondo were women.
b more women in central ondo mainly cultivated root crops than mainly cultivated cereals.
c most of the farmers who mainly cultivated non - root vegetables in north and south ondo were women.
d a relatively equal proportion of women across the three regions of ondo mainly cultivated cereals.

Explanation:

Step1: Analyze Option A

Check the graph for cereal (gray) and non - root vegetable (black) farmers who are women in south Ondo. The gray (cereal) bar and black (non - root vegetable) bar heights in south Ondo: The non - root vegetable (black) bar is taller, so "most of the farmers who mainly cultivated cereals and most of the farmers who mainly cultivated non - root vegetables in south Ondo were women" is incorrect as non - root vegetable farmers (women) are more than cereal.

Step2: Analyze Option B

Look at central Ondo: root crops (white) and cereals (gray). The white (root crops) bar is shorter than gray (cereals), so "more women in central Ondo mainly cultivated root crops than mainly cultivated cereals" is wrong.

Step3: Analyze Option C

Check north and south Ondo for non - root vegetable (black) farmers who are women. The black bar in north Ondo and south Ondo: The heights are different (south's black bar is taller), so "most of the farmers who mainly cultivated non - root vegetables in north and south Ondo were women" is incorrect as the proportions are not the same.

Step4: Analyze Option D

Check the three regions (north, central, south Ondo) for cereal (gray) farmers who are women. The gray bars in all three regions are relatively tall and similar in height, suggesting a relatively equal proportion of women across the three regions of Ondo mainly cultivated cereals.

Answer:

D. a relatively equal proportion of women across the three regions of Ondo mainly cultivated cereals.
