a face mask plastic gloves a ventilator hood insulated gloves
I gave my students this multiple choice question: A student conducts an investigation testing a material's effectiveness as a heat insulator. Which tool will help the student conduct this investigation safely?

Only one answer is correct among these 4 choices:
- a face mask
- plastic gloves
- a ventilator hood
- insulated gloves

Could you tell me which one is correct?
