Question: What is her motive in killing her sister?
Answer: She was hoping that the guy would appear at the funeral again.
If you answered this correctly, you think like a psychopath.
This was a test by a famous American psychologist, used to see if one has the same mentality as a killer. Many arrested serial killers took part in the test, and answered the question correctly.
