An example of a paramagnetic material is
- silver.
- iron.
- glass.
- aluminium.
Explanation
Aluminium is paramagnetic, meaning it is weakly attracted by a magnetic field because of its unpaired electrons. Iron is ferromagnetic (strongly attracted and able to retain magnetism), while silver and glass are diamagnetic and weakly repelled, so aluminium is the only paramagnetic example listed.
obrien99 asking:
Surely this is incorrect too.
iron would fall into the ferromagnet group
silver would fall into the diamagnetic group
glass would fall into the paramagnetic group

This question is a little bit tricky.
First of all silver and glass are diamagnetics, so this two options are wrong answers in that question.
Sure, iron is ferromagnetic, but it becomes paramagnetic above Curie temperature.

Glass is paramagnetic, my mistake.

so the right answer is glass , because it is paramagnetic.
