Demonstrating bravery huh? It doesn't seem too hard to explain. Say, for example your talking about a fictional story, right? Depending on what that said character does, depends on his/her bravery for he/she did. If you can implement something similar to that in whatever it was you had in mind, it might help.
I really hope this helps.
Answer:
C. Every time a certain church bell rings, something terrible happens to Guy
Explanation:
In english, we say that an element is supernatural when it cannot be explicable by scientific laws and therefore cannot be proven as real. Examples of supernatural things are: miracles, ghosts, angels, demons, ufos, superstitions.
Looking at the options we have, option C mentions that every time a certain church bell rings, something terrible happens to Guy. We can see that this is an example of superstition since something terrible is related to the fact that the bell rings or not. Thus, this is an example of a supernatural element.
Options A and D don't have supernatural elements (a haunted house is made by people so it's not supernatural). Option B has the luck element but it's just a thought the Dr has and not really a supernatural element.
