The entity Activity has two properties: "was motivation for (motivated): Conceptual Object", "motivated the creation of (was created for): Conceptual Object".
Either use one property "was motivation for (motivated): Man-Made Stuff" or change range of "was motivation for (motivated):" to "Man-Made Object".
P18 motivated the creation of (was created for) changes to motivated the creation of (was created because of) and has a range of E71 Man-Made Stuff.
This may be the case of a war memorial.
P17 "was motivation of (motivated)" changes its range to E71 Man-Made Stuff.
This may be the case of an written order.
