When we look back in the past of Chilean literature, Manuel Rojas, started his writing career in between the naturalist movement. To understand more, we can relate realism and naturalism. First, naturalists' writing involved an extreme portrayal of realism which focused more on barbaric attributes of the human race. And then, the characters included in such stories belonged to the bottom of the society, with an unsavory description.
We notice a non-participant narrator in this tale of kindness. He's a third-person narrator who is limited to the visuals and physical activities of the characters but has no access to their thoughts. However, he describes the mentality of the young boy. This effect is created to focus more on the conditions and their impact, on the miserable life.
Through this, it is easy to infer that the third choice would get you the best marks.
=> The use of third-person limited point of view allows the reader to better understand the main character.
There are many kinds (can't name them all off the top of my head)
1. Telling someone you'll keep it a secret and then tell anyway...
2. Always being there for someone and then not
3. When you cheat on your husband/wife or someone you're in a relationship with
4. Using someone just to get some
Those are all I can think of (at the moment). But you can just pick whichever one you want.
I believe that the phrase from Mandela's speech that is an example of a metaphor is the first one - 'the children, [...] the greatest of our treasures."
A metaphor is a type of comparison, where two or more things are compared without using words such as <em>like </em>or <em>as. </em>Here, the children are the greatest of our treasures - they are compared to a treasure, something which is the most important thing of all.
