This is very deceptive for perception. The hour hand is so close to the 4 that it is easy to get pulled into 4 o'clock. It looks solidly on the 4. On this problem you are checking perception,not whether or not the student understands the concept of telling time. Even having the hour hand a millimeter or less closer to the 3 would make a difference on perception. Do you have any stats on how many people miss this problem? Are there stats to back up my claim?
