The correct response is:
It is always possible to find a rational number between any two rational numbers.
This is due to the density of rational numbers on the number line; no matter how close two rational numbers are, you can always find another rational number between them. For example, for any two rational numbers \(a\) and \(b\) (where \(a < b\)), the number \(\frac{a + b}{2}\) is a rational number that lies between \(a\) and \(b\).
