To be considered a primary source, a source must be:

a- written or created by an educated expert.

b- written or created by a person who experienced an event.

c- written or created for use as historical evidence.

d- written or created by an object, unbiased person.

the correct answer is c. usually the language, and its emotional insight, that is how feelings and attitudes are expressed through language, are not quite present in film adaptations. despite that, it is a factor that a fan may either not notice or not care much about, especially compared to the other factors.
