Zhao Benshan，whose overworkhis health failure last year，failed to perform in the Spring Festival Gala on CCTV． A. submitted to B. admitted to C. contributed to D. subscribed to

The sentence examines the causal relationship between Zhao Benshan's overwork and his health condition. The key is to select a phrase that indicates "overwork was a factor leading to health failure."

Analysis of options:

Submitted to (屈服于/提交) implies yielding or submitting something, which does not fit the context of cause and effect.

Admitted to (承认) refers to confessing something, such as a mistake, and cannot express a causal relationship.

Contributed to (促成/导致) means to be a factor in causing an outcome, perfectly conveying that overwork played a role in his health decline.

Subscribed to (订阅/同意) relates to signing up for services or agreeing with ideas, irrelevant here.

The logical relationship requires a phrase indicating causation.
