I had to go back through the lessons but for question 3

All group 1 indicators consists of

If

When

Where

All

Every

Any

THE ONLY.*

GROUP 2 INDICATORS

only

only if

only when

only where

always

must

I thought it was group 2 indictor but the statement reads "THE ONLY" which is in group 1 indicator.

Hope this helps because I was confused until I went back through the lessons.
