If you want to randomly display a statement (text or sentence) into a question, you can do this by placing the following code into your question at the place you want to insert the random text:
{if(rand(0,1) > .5,"Question Text 1","Question Text 2")}
Replace Question Text 1 and Question Text 2 with your own statements.
This code generates a random number between 0 and 1, and when it is larger than .5 it shows the first statement, and when less, it shows the 2nd statement.
