re. Analyze each picture carefully. You have to type "Yes" for if you see something, "No" if you do not see anything, and "I don't know" if you are unsure. Despite the text box stating it is optional, DO NOT LEAVE THE TEXT BOX EMPTY. This quiz is to test what you see in an initial scan, so you will only be given 2 minutes to look at each image and to also type your answer before moving to the next question. DO NOT FORGET TO TYPE YOUR ANSWER.
