It is a good conductor. It is a poor conductor. It is highly magnetic. It is nonmagnetic.
I gave my students this multiple choice question: Antonia is testing the properties of block A. • She puts block A on top of a hot metal block and then touches the block A with her finger. • She keeps her finger on the block A for several minutes, but block A still does not get hot. What can Antonia conclude about block A?

Only one answer is correct among these 4 choices:
- It is a good conductor.
- It is a poor conductor.
- It is highly magnetic.
- It is nonmagnetic.

Could you tell me which one is correct?

It is a poor conductor.
