@sevanb This is a super common area of confusion amongst ARE candidates, which is why we actually wrote a full article breaking down the key aspects of it! Check out this post and let me know if you have any further questions:

Also, for future reference - we prefer that you not simply copy & paste the practice exam content into the community. Please provide us with the 5-7 item ID number at the bottom right of your question screen so that we can reference the practice question on our end.
