请教大全-20-9，谢谢！

9.     Mannis Corporation’s archival records are stored in an obsolete过时的 format that is accessible only by its current computer system; thus they are inaccessible when that system is not functioning properly. In order to avoid the possibility of losing access to their archival records in the case of computer malfunction, Mannis plans to replace its current computer system with a new system that stores records in a format that is accessible to several different systems.

The answer to which of the following questions would be most helpful in evaluating the effectiveness of the plan as a means of retaining access to the archival records?

(A) Will the new computer system require fewer operators than the current system requires?

(B) Has Mannis Corporation always stored its archival records in a computerized format?

(C) Will the new computer system that Mannis plans ensure greater security for the records stored than does Mannis’ current system?

(D) Will Mannis’ current collection of archival records be readily transferable to the new computer system?（D）

(E) Will the new computer system be able to perform many more tasks than the current system is able to perform?

请问为什么不选C呢？我以为原文一直强调accessible，那如果引起安全问题比如说record的机密泄露的话，那就不能用新设备了啊，哪位可以帮我讲讲么？谢谢了！！

我觉得C中的security是无关的

D说现有的archival records 能否transferable to the new computer system，如果可以的话就没问题了，如果不行，那现有的archival records 就都不能用了，当然not effective

还是觉得C可以啊~~

question:The answer to which of the following questions would be most helpful in evaluating the effectiveness of the plan as a means of retaining access to the archival records?是不是可以这么理解？

显然C是不对的。

你只要将答案C的问题，回答yes or no，就知道，其对原文的推理没有作用了。

楼上解释的不错，重点看看红色的字体。
