单项选择题
The food was divided ______ according to the age and size of the child.
A. equally
B. individually
C. sufficiently
D. proportionally
答案
参考答案：D
解析： D选项“proportionally按比例地，均衡地”符合题意，如：The pay will be proportional to the amount of time put in．(代价要和所花费的时间成比例)。其他三项“A选项equally平均地；C选项sufficiently充足地；B选项individually单独地，个别地”都不正确。本题空格处是说食物按比例来分。因此D选项为正确答案。
