请教一題語法

Despite the increasing popularity among financial analysts of "operating cash flow" as a measure of a company's viability, a combination of six more conventional measures has been shown to be more accurate to predict business failure.

(A)has been shown to be more accurate to predict business failure

(B)has been shown to predit business failure more accurately

AnswerB)

Why is (A) wrong?

是不是(A)要改成 has been shown to be more accurately to predict business failure

還是有其他(A)的改法??

謝謝

has been shown to be more accurate in predicting business failure

总觉得第2个to用的不太舒服,这里好象没有表目的的意思

LZ的改法我不太认同,n. be more adv.

has been shown 已经是被动了 后面的to be more accurate 又是被动

B的主动优于被动 ，而且句子更简洁
