Isn't (A) just negation of the second sentence, not contrapositive? How come (A) is considered as the must be true? Thanks,

Thanks for your question, @Batman.

As you correctly note, this is a Must Be True question type. Notice that we are told that decentralization enables divisions of large institutions to function autonomously (sentence #1), and that this, in turn, ALWAYS permits MORE REALISTIC planning (part of sentence #2). This is a relative statement--what it means is that planning in large institutions whose divisions function autonomously is MORE REALISTIC (always) than is planning in large institutions whose divisions do NOT function autonomously. That must be true, by the plain terms of the stimulus. It's not an erroneous negation, and it's not the contrapositive. Rather, answer choice (A) must be true because the terms of the stimulus clearly state that decentralization and autonomous divisions always (without exception) allow more realistic planning. Not "as realistic" planning (i.e., not "equal" to non-decentralized, non-autonomous divisions). MORE realistic planning.

Review concepts related to quantifiers and relative statements (more than, less than, equal to, greater than, faster than, at least as fast as, etc.).

Hope this helps! Please let us know if you have any additional questions.

@Mehran, I still don't understand from your explanation herein how (A) isn't a only a negation. Thanks.
