How was that question worded?

How was that question worded?
I'm pretty sure it just said 'what is this reaction called?' or at least something very similar - I just put dehydration because sulphuric acid removes the water from substances but I could be wrong.

Dehydration

Was it addition or condensation polymerisation?
It was addition because it was an alkene that was polymerised, so no small molecules were created. What did you get for the empricial formula?
