Is that the exact way the question is stated? It's confusing. What is meant by "supports"?

Here is exactly what my Prof. says:
a constant-volume thermometer at a certain temperature supports a certain column of mercury. At a different temperature, what would it support?

Have you come up with anything? What relates things like pressure, volume and temperature?

You mean like:
$$\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}$$?
