Hi, I wasn't sure if you wanted answers or corrections, so here are some suggestions to improve the questions: How satisfied do people seem with the amount of money they have? Do people have a good work-life balance? How happy are people with the education they receive? How confident are people that your country's health system will look after them? What kind of food do people eat? Is is healthy or not? How politically engaged are people? How often do people participate in cultural activities? Are people tolerant of different groups in society?

Hi, I recommend thinking about what you want to learn in English. 1. British or American films? 2. Workplace context, fiction, everyday life? 3. Are there particular topics that interest you? Good luck! Kathryn

Yes. I'd often write it in a single line if it's an informal email. Thank you, have a good day Kathryn

Could have sounds more natural to me

You could consider taking lessons from both British and American native speakers to help you get used to the difference. Good luck!

I would use the word "happiness", but check your spelling. Good luck!

Hi, these questions have the same meaning. It's your choice. This also applies in other contexts, for example : Do you want to go out for dinner tonight? Sure, what time? What/how about 7pm?
