How to understand a YAML script to answer questions?

Question

I am going to learn YAML data serialization language, and I want to answer these questions based on a YAML script. What would be the right answers?

I have learned some JSON but to differentiate YAML with JSON & to get an idea of YAML I have found this script with these questions.

{% if country('ae') %}
