What what would you say " Render the text given below"
"Retell the text given below"
If both are accaptable, what option would you use?
In what sense do you mean render? If render is used to mean translate, it would havt to read render the text into English (or another language.)
In that case, I would say interpret or explain.
Please refer to the first thread in this forum posted by RonBee on 30 June 2008, titled "Look it up!" You can find there numerous resources which will help you clarify the definition of interpret.
