GMAT Verbal Reasoning Practice Test 1

The information provided in the passage leads to the conclusion that objects should be dispersed evenly around the room. This would “encourage the free flow of energy” and reduce clutter, because objects would not be crammed together.
Proper ventilation (choice A) may indeed improve the flow of energy, but that cannot be concluded from the passage. The passage does not indicate where square objects should be placed (choice C), whether walls should be kept bare(choice D), or whether light colored paints are best (choice E), so these choices are incorrect.
