Workers first denote if the focus of the image is on the main object (core), or a separate or background object (spurious). They also mark their confidence on a scale of 1 to 5, and provide written explanations for their annotation.

Main Object	3	Red focus is on the mouth of lion.
Main Object	5	The main object is a lion, king of beasts, panthera leo. the focus of the red region on the highlighted visual attributes is on the mammals's (lion) head, showing its main parts. because of that, i choose that focus is on some part of the main object.
Main Object	4	Focus is on the face of the lion.
Main Object	5	Highlighted area is focused on the nose of the lion.
Main Object	5	All photos are of lions, and all photos have parts of lions highlighted red, and i'm confidant because the amplified photo highly resembles a lion.
