I live in Canada, but my family came here from Algeria
Wow!  That is a long way away - did they live in the capital of Algiers?
Yes, they did!  But they decided that they wanted a change, and hence the move to Canada!
Yes.  Canada is a large country, but Algeria is no slouch - it is the 10th largest country in the world.
Wow, I didn't know that!  I bet it has a large population!
I am not sure, but tourism is a growing industry - people want to see the Sahara
