Carl is studying food science at college and hopes to open up meat processing factory of his own one day.
A. /;the
B. the; a
C. /;a
D. the; the

A. /;theB. the; a(答案→)C. /;aD. the; the解析：考查冠词。第一空后的名词food science食品科学；是一个抽象名词，要单独使用，不要冠词。第二空后的名词factory是一个可数名词，用a表示泛指。句意：Carl正在大学里学习食品科学，希望有一天能够直接开一家肉处理的工厂。故C正确。

和我的回答一样，看来我也对了
