It’s a multiple choice that will not only affect what you choose, but also the other side that you didn’t choose. It can also be involved in what your morals choose.
Example:
A train goes into two tracks and you can only pick one.
On one track, there are two elderly women and a dog
On the other track, there is a criminal and a pregnant woman
Answer: there is no right or wrong choice, but no matter what answer you choose, someone will die.
