Cultural bias 

A question in the Algebra I textbook:
The perimeter of a football field is 962 feet not including the endzones. How wide is the football field.
A simple enough question, assuming that the reader knows that a football field is 100 yards long. The illustration accompanying the question almost provides that information, but the yard line markers are not identified with units, so there's no way for the reader to know that they are yard markers and not, say foot markers. Just one of those little cultural things that we can easily be blind to.
