Describe the bug
A clear and concise description of what what you were trying to accomplish and what went wrong. Vague statements like X does not work are not helpful. Imagine if one of your students sent you an email that said, "My program doesn't work, whats wrong with it?" Could you help them with only that to go on?
I am a student. In the Gym Membership Discount( Activity: 3.15.1.1 Poll (most-common-pretest-gym)) and Lucky Number (Activity: 3.15.1.2 Poll (most-common-pretest-lucky)) questions the images of the code options for answers do not load properly and only show 2 little picture icons below the text "Select the correct code for this problem. Only the highlighted lines are different in each option." above the clickable multiple-choice options (1. A 2. B 3. C 4. D) I am using Chrome
