# Instructions

PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY BEFORE BEGINNING:

You are about to be shown a series of images. Please look closely at all parts of the image.

For each image there will also be a pair of description written in text boxes below the image. Your task is to pick which description best matches the image on a scale from 1 to 9. 1 means only the description on the left could describe the image. 9 means only the description on the right could describe the image. 5 means that both descriptions match the image equally well.

Please read the captions carefully and compare them with your image. Your performance will be recorded and analyzed. If you do not take the task seriously we will know and will have to reject your work.

Thank you!
