Create these 4 Test Scenarios for load testing 'get_question' GCF

1. We request first question from the questions_list and its 'thumbs_down' count is zero.
2. We request first question from the questions_list but only the last question from the list has 'thumbs_down' count zero.
3. We request last question from the questions_list and this last question is among the first 3 valid question ('thumbs_down' count is zero)
4. We request some question indexed > 3 from the questions_list while all of the first 3 questions has 'thumbs_down' count zero.

The length of the questions_list should be 10
