How do we know it's a question? The speaker did not raise her pitch at the end of her spoken sentence, which would have indicated that it is a question. Her inflection was the same as a declarative sentence. I wrote the correct words for the sentence, but I was apparently missing the question marks.
That shouldn't count against you. DL ignores punctuation as far as I can tell.
They do seem to ignore most punctuation, however they marked my answer as wrong in this case. This is most likely because my word order was not correct for a question. I wrote "You are sad today". (I didn't reverse subject and verb, since the speaker didn't use a question inflection).
The robot lady has some issues with pitching questions correctly. You shouldn't rely on the audio alone.
Can someone explain why "estan" is used in this instance?
"están" is used here because it's the conjugated form of the verb "estar" , when used with "ustedes".
but this seems to be asking just one person?
Why is that ?
I'm not so sure that this question is being asked to one person.
If I look at the Spanish sentence, it tells me that the question is being asked to more than one person.
The other way around, looking at the English sentence, "Are you sad today" , the word "you" could be singular/plural.
Are you....? can be asking one person or two or more.
"Are you sad today?" can also be translated "¿Estás triste hoy?" or "¿Está usted triste hoy?" Dúo should accept all three.
The plural is clearly used here; that is what I hear. The speaker is obviously referring to two or more people; however, if you were translating from English to Spanish there might be more possiblilities, because then the "you"could refer to bothe the plural and thr singular.
I said, "Are you GLOOMY today?" and was told wrong, even though "gloomy" is one of the listed translations.
"Ye" hasn't been used in formal English in a long time (the OED says that using it as a subject started falling out of use in the 15th century), and I haven't heard anyone actually say it in real life. The Wiktionary tells me that it's still in use in some pockets on the British Isles, but it's not part of standard English anymore.
