答案：
A. The more carefully; the fewer
B. The more careful; the less
C. The more carefully; the less
(答案→)D. The more careful; the fewer
解析：careful形容词，细心的；less更少的，修饰不可数名词；carefully副词，细心地；fewer更少的，修饰可数名词复数。句意：请认真地读每个句子。你越认真，你犯的错误就越少。——谢谢你的建议。固定句式the more，the more越……，越……，前后都用比较级。联系前文be动词are，及下文可数名词复数mistakes，故选D。
