GM97-3-Q9

   Mannis corporation's archival records are store in an obsolete 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 malfuction. Mannis plans to replace its current computer system with a new system that stores records in a format that is accessible to several diffrent system.

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

正确选项D.  will Mannis' current collection of archival records be readily transferable to the new computer system?

我认为肯定答案可以达到强化论证的目的；但是否定答案并不能说明新系统就不能建立，可以重新输入档案以建立新系统。 起不到evaluate 的作用。
谁能帮我解释一下吗？

否定当然就说明“REPLACE”行不通，如果“archival records ”无法转化为新程序，连就基本的“available"都做不到，更谈不上其它的操作了。
你想想如果是一个全国性关于几十年的档案，“重新输入”现实吗？
做GMAT，千万别用中国人惯长绕弯想法，就事论事就可以了，切记！！！

要求评价的是 the effectiveness of the plan as a means of retaining access to the archival records.
If the archival records cannot transfer to the new system,the plan will fail.

Some of my experience: you should find the assumptions and see which choice are related to the assumption(s).

This question, for example, has at least two assumptions:
1.the new system will funtion properly enought to ensure the accessibility
2. the archival is accessible in the new system

The choice answers the 2nd assumption.
Hope it helps.
