years. Except for relative isolated trouble spots like present-day Somalia, 【M3】______

a plant with few stems and more seeds. There is no guarantee that plant 【M9】______
breeders can continue to develop new, higher-yielding crop, but most 【M10】______
researchers see their success to date as reason for hope.
