To compare without knowing which AI made which, ask someone else to save the pictures as A, B and C before you score them, and to tell you which is which afterwards.

Reference answer (open after you score)

A line passes only if every character matches, including capitals, the comma after Saturday, the middle dot and 'am' and 'pm' in lower case. Common failures: letters that look right at a glance but are malformed, a dropped middle dot, '2 PM', an invented subtitle or a fake web address at the bottom.
