Answer:
1) Personal Protective Equipment (PPE)
2) Masks
3) True
Explanation:
I think those would be the right answers to your questions.
My reasoning:
- PPE is used in healthcare to protect people from diseases
- Mask is an example of PPE
- I'm not completely sure about the last question but I said it's true since question one said that PPE helps protect people from airborne and bloodborne disease.
Answer: That's a conspiracy theory, probably not true.
I would say it is most likely skills or information. It can be broadly interpreted in it's contest. It mostly likely co-insides with your required reading terms. I encourage you to use your best judgement.
I would have to say the answer is C.
A is incorrect since hydrogen is not an air pollutant.
B is incorrect because ozone is most definitely one of the top.
And D has cyanide which is a chemical for suicide during wars.
Hope this helps!
