问题 Based on pinto beans and corn tortillas, the Pima Indian have a diet that derives 70 percent of its protein form vegetable sources and only 30 percent from animal foods, the reverse of the typical North American diet.
选项 A、Pima Indian have a diet that derives
B、Pima Indian in their diet derive
C、diet of the Pima Indian derives
D、diets of the Pima Indian have derived
E、diet of the Pima Indians, deriving
答案 C
解析 由句首的based on过去分词短词，决定了A、B中的Pima Indians作主语不恰当，而应由diet作主语。D中用现在完成时毫无根据，本句陈述一客观事实，用一般现在时最佳。E中句子差谓语部分，句子不完整。
