求教 GWD - 31 - Q12 一个选项的理解~~~~

Secret passwords are often used to control access to computerswhen employees as their initials or birth dates. To improve security, employers should assign randomly generated passwords to employees rather than allowing employees to make up their own.

Which of the following, if true, most seriously undermines the conclusion drawn above?

A.If passwords are generated randomly, it is theoretically possible that employees will be assigned passwords that they might have selected on their own.
B.Randomly generated passwords are so difficult for employees to recall that they often record the passwords in places where the passwords could be easily seen by others.
C.Computer systems protected by passwords are designed to ignore commands that are entered by employees or others who use invalid passwords.
D. In general, the higher the level of security maintained at the computer system, the more difficult it is for unauthorized users to obtain access to the system.
E. Control of physical access to computers by the use of locked doors and guards should be used in addition to passwords in order to maintain security

OA：B

正确答案B我明白，可是A为什么不对呢？我的理解A是虽然passwords可以随意设定，但是员工自己能够修改，这样的话不是还是削弱了argument里面要improve secrurity的目的么~~ 难道是我A选项里面theoretically的理解有问题~

A.If passwords are generated randomly, it is theoretically possible that employees will be assigned passwords that they might have selected on their own.
亲爱的你把选项读错了 A的意思是“如果密码随机产生那么可能雇员会被分配自己挑选的密码”
就好像买了一辆车摇号的时候车牌照数字是随机的但也可以花钱买一个漂亮的数字什么88888 168888-，-。。。
employees will be assigned passwords
passwords are selected on employees themselves

it doesn't matter how employees choose the passwords

analogy:
people will be heathier to eat an apple after cleaning it, to improve people's fitness, people should clean apple before eat it...
A. some people prefer 白猫 to 立白。。。=。=（说明洗苹果有不同的方式有人这么洗有人那么洗但是尽管方式很多最终对于洗苹果--→更健康这个逻辑链木有影响）
B. the condition of water used to clean apple is really bad..

现在为什么CD都不提示回复了呢！真是的~~~~
上邪亲爱的真好~总是帮我回答问题

果然我觉得CR这东西一时间钻进去了想不通，就是应该缓两天再仔细想想~
现在看我A的那个选项真的是怎么理解的哟，闹心啊！
上邪的翻译我理解了呀~终于明白了A为什么是个无关选项了。不过我不是特别能够抓住上邪对上面题目的anology，我尝试写一下我所理解的逻辑：
题目中：
P1: the passwords set by initials or bithday are insecure.
P2: the company should randomize the passwords.
C: this measure can improve the security.
weaken?
A. it is possible for the employees to select the passwords by themselves.
B. the passwords will be easily detected by others.

恩抱歉抱歉亲爱的。。现在自己看看好像确实举例举得不是很好。。。
i think the key here is that random number is more security than birth number...if we try to weaken this argument we should find something insecurity of random number. but not how we choose a random number... that is why i write the anology of 白猫and立白....we are told washing can be better and healthier than not washing...if we try to weaken the argument, we should find something bad of washing apples... but not how we wash apples...no matter what detergent is ...

哦哦，这次懂了呀~原来是这样！谢谢上邪~~我这个愚笨的孩纸！

teddybearj4 · 发表于 2012-5-19 11:21:14

嘿嘿~木有木有！这个A现在看来真的是个挺无关的选项了~一开始还是理解有问题呀~
