EOI help required urgently please

Could anybody help clarify what is required in this question?  I don't know if I'm just having a stupid moment or if my brain is actually now definitely fried but it might make more sense to somebody out there....

E4:  Please indicate why your job is skilled.  Give a detailed reason to support your claim for your points.  We recommend that you first check our definition of skilled employment.
You should explain what is in your job description and explain how this is consistant with your occupational tasks for your occupation in ANZSCO.  Also explain how your recognised qualification and/or work experience is relevant to your job.  If you are claiming that your employment is skilled because it will enhance the quality of NZ's accomplishments and participation in that occupational field, explain
1. how your employment will achieve this: and
2. what evidence you can provide to show that you have an international reputation and record of excellence in your occupational field.


Now I've read all the relevant links and am still confused.
 
My husband is in Refrigeration and Aircons (although mainly industrial refrig) and has run his own business in South Africa but works for a major corporation here in the UK.

Please could somebody help?
