He ________ aburrida toda la tarde.

Hola David T.

Great observation—and you're absolutely right to point out that this might feel a bit advanced for A1.

The correct form "he estado" comes from the verb estar in the present perfect tense ("I have been"), which is indeed used when talking about temporary conditions or emotions, like being bored.

While the concept of ser vs. estar is introduced early on, the specific use of estar + past participle (estado) to express how someone has been feeling over a period of time is usually covered more fully at A2 level.

So yes, the lesson it's linked to is A2, not A1, and this might be why it felt unfamiliar in your quiz.

Thanks for pointing that out—your attention to detail is spot on!
