Dear Sir,
Below is my opinion about Question No. 2. in Assignment 1
Question: Changing a habit is more effective when the process involves.
Answer should be "both of these" (Fun&Surprise).
"Any of these" is not an apt answer, because which means both does not work simultaneously.
Actually a Surprise can be a fun. So, My recommended answer is "Both of these".
Thanks,
Vignesh C
