Some people believe that saying that an organization is hierarchical says everything there is to say about how that organization operates. All bureaucratically controlled organizations are hierarchical. Yet the Public Works Department, although bureaucratically controlled, operates quite differently than most other bureaucratically controlled organizations operate.

If the statements above are true, which one of the following must also be true on the basis of them?

(A) The Public Works Department operates more like a nonbureaucratically controlled organization than like a bureaucratically controlled organization. - WRONG. We aren't sure in which manner the PWD works, whether bureaucratically or nonbureaucratically.

(B) Any organization that is hierarchical is bureaucratically controlled. - WRONG. Reverse of the highlighted text that can't be true always.

(C) From the fact that a given organization is hierarchical nothing can reliably be concluded about how that organization operates. - WRONG. The word 'nothing' is a bit on extreme side as there's a probability that hierarchical organization might most likely be bureaucratically operated.

(D) Not all hierarchical organizations operate in the same way. - CORRECT. This one leaves a scope of possibility in its claim, thus a good candidate. Even if it is only one that operates differently, it suggests 'not all' claim is true.

(E) Whether or not an organization is bureaucratically controlled has nothing to do with how that organization operates. - WRONG. Somewhat contradicts the highlighted text.

C and E are good enough to trap people. Just see that the passage starts with 'some' which indicates that it is going to test the blurred line of probability of anything being true or false.

Answer D.

can someone explain the difference between C and D answer choice

Some people believe that saying that an organization is hierarchical.
Some people believe that saying that an organization is hierarchical says everything there is to say about how that organization operates.
All bureaucratically controlled organizations are hierarchical.
Yet the Public Works Department, although bureaucratically controlled, operates quite differently than most other bureaucratically controlled organizations operate.

(A) The Public Works Department operates more like a non-bureaucratically controlled organization than like a bureaucratically controlled organization. Just because their operations are different we cannot go to an extreme of saying that act in a non-bureaucratic way

(B) Any organization that is hierarchical is bureaucratically controlled. Keep it aside

(C) From the fact that a given organization is hierarchical nothing can reliably be concluded about how that organization operates. Nothing is too strong a word. Also, we have been given in the context of the argument that whether a company is hierarchical or not is sufficient to determine how it operates...if it doesn't apply in the case of public dept. doesn't mean that it doesn't apply elsewhere.

(D) Not all hierarchical organizations operate in the same way. Keep it aside

(E) Whether or not an organization is bureaucratically controlled has nothing to do with how that organization operates. Same like C

Now between B & D.
B cannot be inferred ex: public dept organizations.
D can be inferred.
Please look at the attachment.. :)
