Hi McHaynnes

Anna is a teacher.

No clarification necessary, this phrase is basic both for American and British English.

I would be intrigued to hear from the author why it is considered basic American English, and what the British English equivalent is?

cheers stew.t

Hello McHannyes,

The sentences in our Basic American English tests are not necessarily different from the BrE.
