The first part is a cross word puzzle therefore it’s hard for me to do that for you but the second part is words so, "The swimming pool in my town is 50 years old. The pool is 30 metres long and 10 metres wide. The water is 1 metre deep. It is quite big"
C............ glad to help
Intrinsic motivation is a motivation "from inside", with internal, rather than external awards.
Three of the things you mentioned have an external reward: the 500 Dollar prize( first option), the credit (third) and the hope of winning a blue ribbon (the last).
Only the second one has an intrinsic motivation: that you will be happy about performing this song (feeling proud of yourself, etc).
