-				There is a relation between two resources when the former replaces or displaces the latter. The replacement is
-				the result of a "replace" Activity, which used a specialization of the replaced entity (<code>_:oldEntity</code>) and 
-				generated a specialization of the replacement (<code>_:newEntity</code>). Thus, <code>_:newEntity</code> was derived from 
-				<code>_:oldEntity</code>, as it could not have existed without it. However, the derivation relationship cannot always be applied between the original entities, because they 
-				could have existed before the replacement took place (for example, if a book replaces another in a catalog we cannot say that it was 
-				derived from it).
+				There is a relation between two resources when the former replaces or displaces the latter. 
+				However, we can't always assume the replacement is derived from the former resource, because the 
+				replacement could have existed and been generated independently from the original (for instance if a 
+				"Introduction to provenance" book replaces the "Provenance in a nutshell" book in a catalog). 
+				Therefore the "replace" Activity uses a specialization of the replaced entity (<code>_:oldEntity</code>) and generated 
+				a specialization of the replacement (<code>_:newEntity</code>). These specializations model the aspect of the resource 
+				which is the subject of replacement, thus, <code>_:newEntity</code> was derived from <code>_:oldEntity</code>.
