I'm not sure I understand why the 'yang' is included. I wrote, "Saya menarik syal merah itu'.
"Yang" is optional here, so your answer should be ok, please report it
Actually what does it mean?
Pulling a red scarf??
what does yang mean?
I know yang is optional but what is the purpose of it here?
I think "yang" means "that/which" so it's "I pull the scarf that is red"
Let me know if I'm wrong but maybe it gives the nuance that it was picked out of multiple scarfs.
