But alas you are not answering this question. 
For clarification on how I answered the questions (and how I planned to answer them prior to any questions being asked or before I chose an item):
- “Is xxxxx a common [household / bathroom / zoo / etc] item”…My translation would have been “Would this item be found in something like a third or more of [households / etc]” (that third-or-more sounds like a more stringent requirement than some had in mind)
- “Is the item commonly found in xxxxxx” …My translation would have been “GIVEN THAT THIS ITEM IS BEING CONSIDERED, would I expect to find it in xxxxxx”. So even if only 5% of [households] had one, if all the owners kept them in their household, this would be a solid yes.
The latest question, “Does it typically stay in one place”, adds a different type of ambiguity that I’d thought about before starting. I’d answer a question like that as yes if EITHER the object was frequently on the move (like the school bus) OR if the object’s purpose required it to be moved (e.g. a motorcycle, which might only be in motion for 2 hours a week).
Not trying to drop huge hints with this. I just found it a bit amusing that there was back and forth on how “common” might be an easily confusing question, immediately followed by asking what something “typically” does.
