tedmc, it's exactly a question of semantics. It's a test of whether you know the meaning of words - what else would you call it?
Proving oneself smart isn't the point. People post these questions here because they want opinions. We all give opinions, and I'll continue to point out unfair or ambiguous questions if the OP asks.
Why would one consider the idea of extension of a rubber band which springs back to its original size? Or condensing a paragraph of words to make it shorter? Both of which would not lead you to any answer.
