Everything listed below is part of special effects EXCEPT creating explosions on film
finding a location to film a scene
removing blemishes on an actor’s face
making it look like a character is flying?

The correct answer is - because it has been a part of the daily live of a culture.

The Aztec calendar is one of the most famous calendars in the world, though it is not a calendar that is practiced. It has a unique shape and is finely made, having its own unique way of keeping track of the time.

This calendar has been used on a daily basis by the people of the Nahuatl culture, with the Aztecs being the most famous ones. Their lives have been orientated around this calendar, their activities, the agriculture. So we can easily state that the Aztec calendar is a cultural trait of the Aztec civilization, thus having a cultural value as an object.
