23.(i), 23.(ii), 23.(iv) are getting from system properties for each question so script need according to that

[Mark Manders]

If these are questions answered through an assessment, you can just get them from the question results. 

And your last remark about system properties doesn't really make sense, since they are answers to questions. How do they come from system properties? Do know that we don't have access to your instance, which makes it impossible to do anything for you, related to your data. We can only answer what we know and you are providing very little to go on.
