The correct response is:
It is always possible to find a rational number between any two rational numbers.
This is based on the property of rational numbers that states between any two distinct rational numbers, you can always find another rational number. For example, if you have two rational numbers \( a \) and \( b \) (with \( a < b \)), you can find a rational number between them by calculating \( \frac{a + b}{2} \), which will be a rational number that lies between \( a \) and \( b \).
