If a strict vegan were planning a meal with a good mix of amino acids, he or she would probably combine a legume (such as beans) with

a. eggs.
b. leafy vegetables, such as spinach.
c. root vegetables, such as yams.
d. grains, such as rice or wheat.
e. starchy fruits, such as bananas and plantains.


D; Beans and rice are a good combination for complementing the amino acid distribution of a strictly vegetarian dish, the beans compensating for the lysine deficiency in the grain, and the grain supplying the methionine lacking in the beans. Choice a is wrong, because a strict vegan doesn't eat eggs. Choices b, c, and e are wrong, because these plant sources have little protein, and what they do have will not complement the beans.
