Show one of several blocks of text depending on the value of a question variable.
As well as a simple check for the value of a variable, the condition to display a block of text can be a complex expression in any of the question variables - in this example, depending on the discriminant of the generated quadratic.

- Statement
- "Unnamed part" - prompt
Gap-fill
Ask the student a question, and give any hints about how they should answer this part.
First, this question picks between three scenarios.
This is Scenario 1.
This is Scenario 2.
This is Scenario 3.
Now, consider the quadratic equation
{{a}x2+{b}x+{c}=0}
The discriminant of this equation is {{b}2−4{a}{c}}={b2−4ac}. This is greater than zero, so the equation has two real roots. As this is zero, the equation has one repeated root. This is less than zero, so the equation has no real roots.
Use this tab to check that this question works as expected.
There was an error which means the tests can't run:
