This is a diploma level assessment, academic writing is not necessary. No textbook need, all these simple questions can find the answers or solution on google.
Page 3 and page 4 of the assessment (Task 1 and Task 2)
I have also uploaded some support material that you can use for task 2 (instead of the link in task 2).
No words limit, as long as it can answer the question simply and clearly.
Thank you for your help.
