conductor

When the voltage across a certain conductor is doubled, the current is observed to increase by a factor of three. What can you conclude about the conductor?

I have no idea. Please help

Surely, you've covered normal conductors by this time? What's the definition of a conductor's resistance? Did it change when you changed the voltage?

TTFN,

This is a non Ohmic conductor. V = IR does not hold. It could be a forward biased diode or a giant magnetoresistance material or a small gap semiconductor. It is not metallic.
