Some of the choices seem poorly selected. For example, on the question about what term I would use for roads meeting in a circle, both "roundabout" and "rotary" were choices, but I was only allowed to select just one. I use both terms, but it depends on the exact road configuration, and to some degree, the context of who I am speaking to. Other questions had similar issues.

I tend to code-switch when speaking if I can. If I'm talking to a New Yorker I'll say "truck" and "apartment", but to a Londoner I'd be more likely to say "lorry" and "flat".
