Answer:
Flashback
Explanation:
The following sentence “ even after all these years” shows that this event happened in the past. “ This couldn’t possibly again” also shows proof that it is a flashback.
The correct answer to this open question is the following.
Although you forgot to include the name of the documentary or a link to it, we did some research to find what you are talking about.
You are referring to the documentary titled "It Takes a Child: Craig Kielburger's Story. A Journey into Child Labor," produced by Craig Kielburger.
After watching the documentary, I think it was important for Kielburger to make the documentary because it was a professional way to document this sad situation in south Asia countries and expose the problem to the world to create awareness of this terrible issue of exploiting children through labor in that region.
The result and acceptance of his documentary helped him to found the non-governmental organization called "Free the Children" that has thousands of members in 20 countries.
A direct comparison is a metaphor.
