This is my first time to attend such a contest. Thanks for giving such a nice contest. I am waiting to see what the answer will be. Hope my answer is correct.

1. (Repeat/Switch):
   It’s Repeat Sign but for this answer we can think is as Switch.

2.(Jar/Zar):
It’s a Jar sign but for this answer we can change it’s spelling as Zar.

1. (Iseland/Land):
   It’s Iseland sign. Switzerland is a winter country, with frequent blizzards and many areas covered in snow. So we can call Switzerland as an Iceland.

Switch+Zar+Land
