Can you add the passages if possible in not familiar with the mwb
Nationality would be the country a person was born in. Ethnicity would be their ethnic or racial background.
Example:
A person could be born in Canada and be Canadian but their ethnicity could be something like Chinese or African.
I wouldn’t say you’d ask anything at the end. You should always say “It was a pleasure meeting you sir/m’am” or “Thank you for your time”. It’s always good to be polite and show a sign of respect
I would like to say the answer is "true"
