According to my research on National Association of School Resource Officers, I can say that based on the information provided within the question calculations show around from 14,000 and 20,000 SROs providing protection in schools nationwide. SRO's are sworn law enforcement officers responsible for keeping schools and the people within them safe.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
I'm not so sure about the anwer for this one, since there are no options for the expected answer (evethough is a which question), BUT, I would say is: bordering countries, given that the United States of America shares borders with both of these two countries.
Another acceptable, yet less formal, term would be neighbour countries. But, I'd rather use the first one.
