Chapter 3 $graphLookup: maxDepth and depthField

I’m sorry if I’m wrong, but I think the answer of the quiz related with maxDepth and depthField is different from the explanation from the video. Or am I misunderstanding things?
For example:

depthField determines a field, which contains value of the number of documents matched by the recursive lookup

this is the correct answer from the quiz

I think the correct answer should be:

depthField determines a field in the result document, which specifies the number of recursive lookups needed to reach that document

Hi @Hendry_Willy,

You are correct, but the exercise is to select which ones are incorrect.

Ah I see, I misread that part. Thank you for clarifying
