English Evolution Test -- I FAILED! (even the easiest of the levels)

I consider myself a pretty decent speaker of my native language, English.  I even consider myself a pretty decent speaker of one other language, as well.  According to a recent Facebook post citing an article discussing at what point one might reasonably say that he "speaks" a language, I felt modestly proficient at both. 

--uh, well, until I took this test:

Evolving English: One Language, Many Voices

I didn't notice until after the test started that this test is apparently intended for native speakers of Brittish English. 

Well, that, or I'm not as sharp as I thought I was. 

  

As likely the latter as anything, I'm sure.
