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".

At least a solid third of the questions I wanted to check multiple boxes and a lot of it is context dependent or some terms are more specific than other terms but both work.

Rotary/roundabout

Yard sale/tag sale/garage sale

semi/semi truck/semi trailer/tractor trailer

sneakers/gym shoes

I suspect they didn't have a large enough sample size to allow multiple selections while still having the desired accuracy so they force you to pick something.

What’s the difference for you?

In general...

rotary: tangential entry/exit, large diameter, high-speed, multi-lane

roundabout: deflected entry/exit, small diameter, low-speed, sometimes single-lane

Size and number of lanes, for me. I think roundabouts are the multi-lane ones, rotaries are much smaller and slower usually. At least this is what I realized on moving from Massachusetts where rotaries were common, to New Jersey where there were many "roundabouts" which required lane changes and no reduction of speed.
