A-Level energetics!

Hi,

I got this question and know how to carry out the calculation. However on the mark scheme there is a mark for drawing the Hess cycle - What indicates I need to draw the Hess cycle as majority of AQA bond enthalpy calculations you don't get a mark for drawing the cycle (this is the first question i've seen where you have to so maybe this is an old spec AQA question?)

How do I draw the Hess cycle for bond enthalpies correctly and is it any different to the Hess's cycle for formation/combustion calcs?

It's Q15 d on this: https://www.physicsandmathstutor.com/pdf-pages/?pdf=https%3A%2F%2Fpmt.physicsandmathstutor.com%2Fdownload%2FChemistry%2FA-level%2FTopic-Qs%2FAQA%2FPhysical-I%2F1.4-Energetics%2FSet-I%2FEnergetics%2520QP.pdf

Thanks
