问个逻辑题,TEST 20-9

Mannis Corporation’s archival records are stored 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 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 oper-

ators 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?

(E) Will the new computer system be able to perform

many more tasks than the current system is able

to perform?

答案是D。请问怎样排除C呢?我做这道题的时候在C和D犹豫了半天,最后选了D。但是心里觉得C也是对的。请指点迷津。谢谢。

原文的意思是:旧系统不稳定(inaccessible),所以要换新系统(accessible)。C 的情况在原文之外,即原文没有提及系统的安全性。C具有迷惑答题的功能。
