问题 Not until the advent of histochemistry could the anatomist see through the microscope which cells carry specific enzymes or gauge how active these enzymes are in different cells under various conditions.

选项 A、discern
B、grasp
C、measure
D、estimate

答案C

解析 gauge意为“测量”。C项measure“测量”符合题意,如:Mother measured me to see what size of dress I should have.(母亲给我量尺寸,好知道我该穿多大号的衣服。)其他三项discern“目睹”,grasp“抓住”,estimate“估计”都不正确。
