正确答案：CE
解析：
"...uncanny ability...role" indicates that the actress is an amazing talent. The 'despite' shows us that the actress does not agree with this perception (notice self-effacing). That is she does not think her success can be chalked up to her talent, but to some outside agent: in this case, lucky breaks, or fortuitous/chance occurrences.

(A) and (B) are too negative. (D) and (F), while synonyms, don't quite fit the context. How would a predictable occurrences be an alternative explanation for the actress's success?
