Someone help me with these questions 15 and 16. You can do 17 if you’d like

For question 15, we use cloths, heat-resistant gloves. (From what I know, I am just a 7th grader. Forgive me.)

For question 16, we use bowls to drink soup, metal cans which we use to drink soda from, we use lunch boxes which are insulated or thermos can be used for bringing to school to eat lunch and keeping food warm, we use aluminium foil containers to keep food warm.

For question 17, I think it's related to chart above question 15 and etc, if it isn't then I don't think I may be able to help.
