Sounds like these items may be known to adults but not to most children due to technology changes throughout society in recent decades. Some may say that age or generation, not culture per se, would be a factor in being familiar with these items? Possibly all children of today are equally disadvantaged regarding these items? While these items were familiar for many decades, possibly the tests are now outdated and need to be updated periodically?
