Answer
Sample answer:
they have the same mass, but different specific heats, or
they have the same specific heats, but different masses.
Work Step by Step
From the equation for specific heat,
$c=\displaystyle \frac{Q}{m\Delta T}$, we express $\displaystyle \Delta T=\frac{Q}{mc}.$
We read from here that if $\Delta T$ is to be the same, then, for both objects, $Q=mc.$
Two examples when this could happen are:
they have the same mass, but different specific heats, or
they have the same specific heats, but different masses.
In any case, the term $mc$ is equal for both objects.
