what technique is this?

[Glitter Muffin xox]

For my section 3 of paper 1. i was going to use this quote and i can't find the right technique for it.
"A lonely child who believed death was clean and final, not this obscene"  ,Barn owl  by Gwen Harwood

Also for paper two can i use a short flim (more by Mark Osbourne) as related text for module C exploring transitions? i analysed it in class so i think its fine but i am making sure since the hsc is different. the link is here  https://www.youtube.com/watch?v=cCeeTfsm8bk
