Accessing a nested collection value from an array

Hi. I have a collection in my quiz app:

ClearCollect(
    appQuestions,
    {
        ID:1, 
        Question: "This is question 1?", 
        Answers: ["Answer 1", "Answer 2", "Answer 3", "Answer 4"]
    },
    {
        ID:2, 
        Question: "This is question 2?",
        Answers: ["Answer 1", "Answer 2", "Answer 3", "Answer 4"]
    }
)

I am struggling with the First/FirstN/Last syntax to access an answer at an index value.

I can get to the question with LookUp(appQuestions,ID=1,Question) but how do I get a specific answer?
I have tried Last(FirstN(LookUp(appQuestions,ID=1,Answers),2)) but this doesn't work.

Hi @rwittels,

The Question is 

 LookUp(
   appQuestions,
   ID=1
).Question

If you are looking for Answer 2 as the answer

Last(
   FirstN(
      LookUp(
         appQuestions,
         ID = 1,
         Answers
      ),
      2
